Preface
The stratigraphic record is the major repository of information about the geological history of
Earth, a record stretching back for nearly 4 billion years. Stratigraphic studies ll out our
planet ’s plate-tectonic history with the details of paleogeography, past climates, and the record
of evolution, and stratigraphy is at the heart of the effort to nd and exploit fossil-fuel resources.
The exploration of this history has been underway since James Hutton rst established the
basic idea of uniformitarianism toward the end of the eighteenth century, and William Smith
developed the stratigraphic basis for geological mapping a few decades later. Modern strati-
graphic methods are now able to provide insights into past geological events and processes on
time scales with unprecedented accuracy and precision, and have added much to our under-
standing of global tectonic and climatic processes. But it has taken 200 years and a modern
revolution to bring all the necessary developments together to create the modern, dynamic
science that this book sets out to describe.
It has been a slow revolution, but stratigraphy now consists of a suite of integrated concepts
and methods, several of which have considerable predictive and interpretive power. It is
argued in Chap. 1 of this book that the new, integrated, dynamic science that stratigraphy has
become is now inseparable from what were its component parts, including sedimentology,
chronostratigraphy, and the broader aspects of basin analysis. In this chapter, the evolution of
this modern science is traced from its nineteenth-century beginnings, including the contri-
butions that such special elds as facies analysis, fluid hydraulics, plate tectonics, and the
reflection-seismic surveying method have made to its evolution.
The following are just some of the major features of the stratigraphy of the early
twenty-rst century: Sequence stratigraphy has become the standard methodology for docu-
mentation, mapping and interpretation, replacing the old descriptive practices of lithostratig-
raphy; reflection-seismic methods, including the use of 3-D seismic and the application of
seismic geomorphology, have become steadily more advanced tools for subsurface exploration
and development; the Geological Time Scale is being standardized with the universal adoption
of the system of Global Stratigraphic Sections and Points (GSSPs) and has become much more
precise, with the incorporation of several new methods for evaluating deep time.
The basic eld and subsurface observations on which stratigraphy is based are described in
Chap. 2. Facies analysis methods are detailed in Chap. 3, and the recognition of depositional
environments by facies methods is described in Chap. 4. Chapter 5 provides a succinct
summary of sequence models for siliciclastic and carbonate sediments, and Chap. 6 describes
modern mapping methods for use in surface and subsurface studies, including seismic
methods. The synthesis of all this material is detailed in Chap. 7, which includes a discussion
of the current attempts to standardize sequence-stratigraphic terminology and the Geological
Time Scale.
Chapter 8, the concluding chapter of the book, focuses on the new understanding we are
acquiring about the processes by which the stratigraphic record preserves elapsed geologic
time. Renements in chronostratigraphic methods are revealing the importance of breaks in
the sedimentary record and the ubiquity of missing time, and are revealing an important
disconnect between sedimentation rates and preservational processes operating at the present

day versus those we interpret from the rock record. This calls for a signicant modication in
the way that we apply the traditional principles of uniformitarianism to our reconstructions of
geologic history.
The new synthesis that is the subject of this book is offered for advanced undergraduate and
graduate training and for use by professionals, particularly those engaged in mapping and
subsurface exploration and development.

Revision History
My rst book, Principles of Sedimentary Basin Analysis, has gone through three editions,
published successively in 1984, 1990, and 1999. A year or so ago, I realized that it might be
time for a new edition. In reviewing the changes that have taken place in the whole broad eld
of sedimentary geology since that last edition, it became clear that stratigraphy is the area that
has undergone the most signicant changes in the last decades, and that is what I decided
would most usefully be treated at length in this book.
Stratigraphy has undergone a revolution that has brought together multiple developments
dealing with different themes and concepts in sedimentary geology and basin analysis.
Chapter 1 includes a new section in which I trace the evolution of these many themes, andattempt to show how they have come together during the last few decades (since about 1990).
The text of Chaps. 2 and 4 from Principles has been updated and becomes Chaps. 2–4 in
the present book. Chapter 3 of Principles, which dealt with dating and correlation, and the
formal methods for the denition and naming of units, has been substantially rewritten and
incorporates much of the material I wrote for “Sophisticated Stratigraphy,” a review prepared
at the invitation of the Geological Society of America (Miall 2013). It has been moved further
along in the present book, appearing as Chap. 7, the point being that stratigraphy should now
be seen as a science that synthesizes sedimentary geology, and which therefore requires that
the subject is best addressed once the work of sedimentological description and interpretation
is underway.
Chapters 5 and 6 of the present book are those that have undergone the most complete
rewriting, to reflect the major changes in the science since the previous edition. Sequence
stratigraphy (Chap. 5) has become the standard method for formal description and paleo-
geographic interpretation, and mapping methods (Chap. 6) are now dominated, at least in the
petroleum industry, by the techniques of the reflection-seismic method, including 3-D seismic
and the interpretive methods of seismic geomorphology.
The book culminates with Chap. 8, which is intended primarily as a review of current
research into the nature of deep time as preserved in the sedimentary record. It is partly based
on two research publications (Miall 2014b; Miall 2015) that focus on modern data dealing
with sedimentation and accommodation rates, and the implications of these data for strati-
graphic interpretation. The chapter concludes with a review of the current advanced research
into cyclostratigraphy and astrochronology.

1.1 The Importance of Stratigraphy
It could be argued that in some respects Stratigraphy is the
most important component of the science of Geology. Here’s
why:
McLaren (1978) provided nine reasons why the study of
Stratigraphy with, at its center, an accurate geological time
scale, is important:
[Stratigraphy supplies unique and essential information regard-
ing:] (1) rates of tectonic processes; (2) rates of sedimentation
and accurate basin history; (3) correlation of geophysical and
geological events; (4) correlation of tectonic and eustatic events;
(5) are epeirogenic movements worldwide [?]… (6) have there
been simultaneous extinctions of unrelated animal and plant
groups [?]; (7) what happened at era boundaries [?]; (8) have
there been catastrophes in earth history which have left a
simultaneous record over a wide region or worldwide [?]; and
(9) are there different kinds of boundaries in the geologic suc-
cession [?] (That is, “natural” boundaries marked by a world-
wide simultaneous event versus “
quiet ”
boundaries, man-madeby denition).[question marks added]
Doyle and Bennett (1998, p. 1) stated that “Stratigraphy
is the key to understand the Earth, its materials, structure and
past life. It encompasses everything that has happened in the
history of the planet ” In this statement is the recognition that
the stratigraphic history of layered sedimentary rocks pre-
served on the continents, and on the ocean floors constitutes
the documented record of Earth history. No other branch of
geology can provide this information.
Berggren et al. (1995, p. v) explained that the “essence of
Stratigraphy and its handmaiden Geochronology” is to
“understand the dynamic relationship which certainly existsbetween the evolution of ocean-continental geometries and
concomitant changes in the climate and ocean circulation
system and the evolution of life itself ” by situating “the
progression of events in this intricately related system in a
precise temporal framework.”
Torrens (2002, p. 251) pointed out a unique and essential
component of stratigraphy: “The science of geology is all
about time. … So stratigraphy must rst and foremost
concern questions of time. It is the only area of geology that

is truly unique, other branches of geology are too often
borrowed bits of physics, chemistry or biology.”
The world’s rst stratigrapher was William Smith, a canal
surveyor, who produced the rst regional geological map in
1815, covering England, Wales and part of Scotland. The
construction and renement of geological maps, and the
documentation of the subsurface for the purposes of petro-
leum and mineral exploration, have constituted two of theprimary activities of practicing stratigraphers worldwide for
the past 200 years. Dating and correlating the rocks have
formed an integral part of this work, and questions about the
nature of the time signal preserved in stratigraphic succes-
sions, and the developments of methods to investigate it
have constituted a large part of this activity. William Smith’s
principal theoretical contribution — which is what made
geological mapping possible — was the recognition of the
reliability of the fossil record: the same assemblages of
fossils always occur in the same order, and thus were born
both the method of relative age-dating and the rst reliable
method for correlation on the basis of time.
As I demonstrated in my review paper for the Geological
Society of America (“Sophisticated Stratigraphy”: Miall
2013), modern stratigraphic methods are now providing
extraordinary insights into the history of our Earth. Modern
methods of age-dating and modern analytical methods have
revolutionized the business of historical geology. In the
drive to develop and apply ever more precise laboratory
methods to geological samples, whether this be with the aim
of age dating or the reconstruction of past climates, it is all
too easy to lose sight of exactly where samples come from
and what was their eld context. How typical and how
representative are samples, relative to the variability of their
eld setting? How were they situated with respect to breaks
in sedimentation, the record of rare events, or disturbance
induced by bioturbation or syn-depositional tectonism?
Specialists in quantitative methods, particularly geophysi-
cists, and those using numerical and statistical methods,
including models and simulations, may be particularly sus-
ceptible to these hazards. One of the key elements of the
stratigraphic data base is therefore eld context . What is the
stratigraphic and sedimentologic setting of the rocks that we
are using to make these sophisticated interpretations? This is
one of the unique characteristics of the science of stratigra-
phy, of particular relevance to the reconstruction of events in
past time.
Until the 1960s, stratigraphy was largely a descriptive
science, concerned primarily with the documentation of the
lithologic and biostratigraphic successions of sedimentary
basins as a basis for locating and exploiting fossil fuel and
mineral deposits. Textbooks on petroleum geology, such as
Levorsen (1954), contain some of the most advanced and
detailed treatments of stratigraphy as actually practiced in
the eld. In many respects, William Smith’s focusing on
basic mapping survived as a central focus through several of
the revolutions that were took place in the earth sciences,
beginning in the 1960s. However, over the last fty years a
profound change in approach has taken place, initially under
the rubric of Sedimentology, which took sedimentary
geologists away from description and classication into a
focus on processes (Seibold and Seibold 2002, provided a
detailed history from a European perspective; see alsoMiddleton 2005). Only in recent years have Stratigraphy,
Sedimentology and Basin Analysis come together to pro-
vide a dynamic, unied approach to the study of sedimentary
basins. It would now be accurate to state that “Stratigraphy
IS Sedimentology and Sedimentology IS Stratigraphy.”
The evolution of modern methods can be understood as a
series of separate developments that partially overlapped in
time and which have gradually coalesced to create, in my
review written for the Geological Society of America (Miall
2013), what I called “Sophisticated Stratigraphy.” Middleton
(2005, p. 628) suggested that:
Only after 1950 was it common to nd specialists who studied
sedimentary rocks, but declined to be called stratigraphers, and
since 1977 an increasing number of specialists refuse to make a
hard distinction between sedimentology and at least some
aspects of paleontology and stratigraphy, which they include
together as “sedimentary geology.”
Some of the developments in the study of sedimentary
rocks were initiated many years ago, but it has only been
since sequence stratigraphy matured as a standard descrip-
tive and mapping method during the 1990s that it has
become apparent that it has drawn on, exploited, and pulled
together these earlier developments that commonly tended to
be considered and written about in isolation. The historical
evolution of these concepts is summarized in the next
section.
1.2 The Evolution of “SophisticatedStratigraphy”
The roots of modern, dynamic stratigraphy go back to the
recognition of the concept of facies in the early nineteenth
century, but it is argued here that the modern era began with
the increased understanding of fluid hydraulics and cyclic
sedimentation and the evolution of the facies model con-
cept in the 1960s. The evolution is broken down below into
fourteen steps. A critical fteenth strand of development
concerns the developments of concepts about geologic time
and the increasing accuracy and precision with which
geologist can now reconstruction the ages of events in the
distant geological past. This topic is addressed in Sect. 7.8.
These strands of development did not take place in isolation;
however, they represent separate concepts or areas of spe-
cialization, which took some time to come together into the

unied, integrated science that is now practiced. This sum-
mary is intended only to touch on the main highlights. A full
historical and analytical account remains to be written. Many
of the publications listed have become classics, with many
hundreds of citations.
1.2.1 Beginnings (Nineteenth Century)
Middleton (2005) divided the history of sedimentology into
six periods or stages. The rst stage ended about 1830 with
the publication of Lyell’s (1830) masterwork, that led to the
general acceptance of uniformitarianism, or actualism, as
the basis for geology. What follows in this section falls into
his second period. The subsequent discussion does not
adhere to his subdivision into “periods” because I focus on
specic themes which overlapped in time.
Two key early developments were the recognition of the
concept of facies (Gressly 1838), and the establishment of
Walther’s Law (Walther 1893–
1894). Teichert (1958),Middleton (1973) and Woodford (1973) reviewed the his-
tory and use of the concepts in light of contemporary ideas.
Note the dates of these papers (1958, 1973), in light of the
stages of development summarized below, because they help
to explain the chronological evolution of modern strati-
graphic thought and theory. Walther ’s law is discussed
further in Sect. 3.4.1.
Developments in biostratigraphy were enormously
important, in establishing some of the basic ideas about
stratal succession, relative ages, and correlation. The evo-
lution of the concepts of zone and stage are discussed in
detail elsewhere (Hancock 1977; Miall 2004), topics that are
not repeated here. Stratigraphic paleontology was a central
theme of stratigraphy until relatively recent times. In fact, the
rst professional society in the eld of sedimentary geology,
the Society of Economic Paleontologists and Mineralogists,
founded in Tulsa in 1931, emphasized this fact in the title of
the society. Paleontology and mineralogy were important
elements of petroleum geology and basin analysis until the
seismic revolution of the 1970s, mainly because of their use
in the identication and correlation of rock units in
petroleum-bearing basins.
1.2.2 Cyclic Sedimentation (1932–1968)
Implicit in the early work on facies and on Walther ’s Law is
the concept of recurrence of certain environments and their
deposits. The idea of cyclicity became explicit with the study
of the Carboniferous deposits of the US Midcontinent in the
early 1930s, which consist of repetitions of a coal-bearing
clastic-carbonate succession. These came to be
called cyclothems. Wanless and Weller (1932, p. 1003) are
credited with the original denition of this term:
The word “cyclothem” is therefore proposed to designate a
series of beds deposited during a single sedimentary cycle of the
type that prevailed during the Pennsylvanian period
Shepard and Wanless (1935) and Wanless and Shepard
(1936) subsequently attributed the cyclicity to cycles of sea-level change, an explanation that has never been
challenged.
The beginnings of an understanding of the signicance of
the lithofacies signatures of common environmental settings
is implicit in the paper by Nanz (1954), where coarsening-
and ning-upward trends extracted from some modern sed-
imentary environments in Texas are presented. There is no
discussion of repetitiveness or cyclicity in this paper, but the
work was clearly foundational for the very important papers
by Nanz’s Shell colleagues that followed less than a decade
later (see Sect. 1.2.6).
Duff and Walton (1962) demonstrated that the cyclothemconcept had become very popular by the early 1960s. For
example, Allen (1962, 1964), who is credited as one of the
two originators of the meandering-river point-bar model for
fluvial deposits, used the term cyclothem for cycles in the
Old Red Sandstone in his rst papers on these deposits. Duff
and Walton (1962) addressed the widespread use (and mis-
use) of the term cyclothem, and discussed such related
concepts as modal cycle, ideal cycle, idealized cycle, and
theoretical cycle, the differences between cyclicity, rhyth-
micity and repetition, and the possible value of statistical
methods for rening cyclic concepts. They speculated about
the possibility of repeated delta-lobe migration as a cause of cyclicity, in contrast to the prevailing interpretation of the
cycles as the product of sea-level change.
With Carboniferous coal-bearing deposits as the focus,
two edited compilations dealing with cyclic sedimentation
made essential contributions to the birth of modern sedi-
mentology at about this time. Merriam (1964), based in
Kansas, provided a focus on the US Midcontinent deposits,
while Duff et al. (1967) dealt at length with European
examples. The Kansas publication included a study of cyclic
mechanisms by Beerbower (1964) that introduced the con-
cepts of autocyclic and allocyclic processes. Autocyclic
processes refers to the processes that lead to the naturalredistribution of energy and sediment within a depositional
system (e.g., meander migration, shoreline progradation) —
the preference is now to use the term autogenic because they
are not always truly cyclic — whereas allocyclic (allogenic)
processes are those generated outside the sedimentary sys-
tem by changes in discharge, load, and slope. Beerbower
(1964) was dealing specically with alluvial deposits in this
paper, but his two terms have subsequently found universal

application for other environments and their deposits. The
term allogenic is now used to refer to processes external to a
sedimentary basin, including eustasy, tectonism and climate
change.
Another important contribution at this time was that by
Visher (1965). The purpose of his paper was to build on the
ideas contained in Walther ’s Law to highlight the impor-
tance of the vertical prole in environmental interpretation.He provided detailed descriptions of the proles for six
clastic environments, regressive marine, fluvial (channel or
valley-ll), lacustrine, deltaic, transgressive marine, and
bathyal-abyssal, drawing on both
