in uneven and patchy extinction of quartz grains. Feldspar grains commonly show

the beginings of core and mantle texture. "Cores" are large (strong) porphyroclastic

feldspar grains, possibly microfractured, while the "mantle" (also termed "mortar") is

composed of relatively finer grains of (typically) feldspar. The finer grained feldspar

mortar is derived from the porphyroclastic feldspar grains and has separated largely

through grain boundary migration recrystallision in attempts to recover from

dislocation tangles (these can be reduced through dislocation climb only at higher

temperature; >400°C). Between approximately 400-600°C, diffusion assisted-

dislocation processes in quartz are more prevalent and extensive quartz subgrain

development and subgrain rotation recrystallisation operates. Passive flattening of

quartz grains passes to wholesale recrystallision at higher strains and leads to very

continuous monomineralic ribbons of quartz. Feldspar grains develop extensive

augen/mantled porphyroclasts with finer grained feldspar also forming ribbons.

Above about 600°C, quartz and feldspar show somewhat similar textures; grain

boundaries may be cuspate/lobate, and diffusion creep processes (Nabarro-Herring,

or "volume diffusion" and Coble, or "boundary diffusion") are thought to play a

major role. Such finely-grained microtextures (e.g., 20-40µm) were not observed,

however, in any of the thin sections examined from NPHM.

5.9.3. Samples and thin sections from Nanga Parbat

5.9.3.1 Samples from Nanga Parbat

All samples that I collected in Nanga Parbat are detailed in three tables (5.2,

5.3, and 5.4) for 1995, 1996, and 1997, respectively. Nomeclature is straightforward:

In 1995, NE95/27-V indicates 1995, 27th (of August), 5th sample collected since

begining of day. NE95/8-V indicates 1995, 8th (of September), 5th sample collected

since begining of day. In 1996 and 1997, a longer field season necessitated using a

term for the month; E6/10/10-I indicates 1996, 10th (of October), 1st sample

268

collected since begining of day. E7/9/14-IV indicates 1997, 14th of September, 4th

sample collected since begining of day. Where a thin section accompanies a sample,

it is listed directly below the sample name, preceded by the batch number in bold.

For example, NE95/26-V T/S1 5/26E indicates batch number 1. All thin section names

are simple versions of the field name, truncated for chip labelling procedures.

Most samples remain housed in the Albany Geology Department archives.

Some samples have been given away or consumed in other labs however. These are

detailed with the recipient's initials and these are included in table 5.5 -

Abbreviations used in other tables.

A description of simple lithology, location and an outcrop number (or

distance to a nearby outcrop number) are given (outcrop numbers also appear on the

map (plate 2) and in the text). Where appropriate, elementary remarks relating to

structure are made for samples that have not been thin sectioned. GPS location

numbers are provided for 1996, where they exist).

5.9.3.2 Thin sections from Nanga Parbat

Approximately 75 thin sections were prepared from chips cut by me. Where

the sample bears marks to allow restoration of field orientation, the chip is

accordingly marked to preserve record of the orientation. Preservation in the thin

section of the original sample orientation from the field is essential for sense of shear

analyses. Thin sections accordingly are prepared from samples oriented in the field

and subsequently cut parallel with mineral lineation, perpendicular to main foliation

(see section 5.9.1 sense of shear analysis and (e.g.) figs 5.9 and 10.1 in Passchier and

Trouw, 1996). A cut is made in the upper (with respect to original field orientation)

part of the sample and either the top left or the top right will point towards the

plunging lineation. For example, from a 45°W dipping foliation, with 30°S plunging

lineation, the top left cut in the thin section will point towards 30°S perpendicular to

269

the 45°W dipping plane. Alternatively, if the lineation was 30°N plunging on the

same plane, the cut will be in the top right of the thin section and will point towards

30°N, again perpendicular to the 45°W dipping plane.

There are two situations where the scheme must be modified:

1. In cases where foliation is near or actually vertical, there is no "upper" part of

the sample (with respect to original field orientation), and I have employed a scheme

I term the "overhead rule"; whereby the top of the right hand edge (TR) of the chip

must point with the lineation plunge direction when the sample is viewed overhead in

original outcrop orientation. This scheme cannot be used in the unique situation

where foliation is truly vertical and lineation is truly horizontal, but this was not

encountered.

2. In cases where the lineation is horizontal, the top of the right hand edge (TR)

of the chip is kept as upper surface with respect to original dip in field (because cut is

always perpendicular to foliation). This scheme cannot be used in the unique

situation where foliation and lineation are both truly horizontal, but this was not

encountered. Three tables of thin sections are included. Each of the tables details a

particaular post-field season batch of thin sections, and in ths way is suited to be used

in conjuction with the box(es) containing a particular batch. Therefore, samples from

1995 appear in all three lists, samples from 1996 appear in two lists, and samples

from 1997 appear in only one list. Batches are numbered T/S1, T/S2, and T/S3.

Thin section names are a simple form of the parent sample name (with equivalents

listed in the samples tables). For example NE95/12-XII is abbreviated to 5/12L.

E6/10/10-I is abbreviated to 610/10A. E7/9/14-IV is abbreviated to 79/14D. Note

that NE95/8-XV is abbreviated to 5/8P (the letter P, obviously, has the 16th position

in the alphabet but "O" was ommitted for clarity).

All thin sections remain housed in the Albany Geology Department archives.

None have been given away.

270

In the thin sections tables, information from the samples tables is duplicated,

and additional general microstructural notes are made for thin sections that are of

interest to the specific investigations in this thesis.
