1. Welcome to the HSTG newsletter

Welcome to our new Newsletter! It is our pleasure to share with all of you the involvements

and activities of this Group with the aim that you get implicated with them as much as

possible. We hope to send this newsletter to you once a year and receive feedback from you in

order to improve it every issue!

The Newsletter will only be available electronically, sent to all HSTG members and available

for download at www.globalheritagestone.org .

2. An overview of the HSTG

HSTG is a Task Group, formally established by the International Union of Geological

Sciences (IUGS) in 2011, with an initial administrative Board of Management being

appointed at the 34th International Geological Congress in Brisbane for the period 2012-2016.

HSTG had earlier origins in 2008 as a project within Commission (C-10) - Building Stones

and Ornamental Rocks of the International Association for Engineering Geology and the

Environment (IAEG C-10) that was recognised at its meeting during the 33rd International

Geological Congress in Oslo, Norway.

The first board of the HSTG is made up of:

PRESIDENT

Dr Björn Schouenborg (Sweden)

SECRETARY GENERAL

Associate Prof. Barry J. Cooper (Australia)

VICE PRESIDENTS & BOARD

MEMBERS

Prof. Dolores Pereira (Spain)

Dr Sabina Kramar (Slovenia)

Prof. Jan Elsen (Belgium)

Dr Joseph T. Hannibal (USA)

Prof. Brian R. Pratt (Canada)

Dr Nelson R. Shaffer (USA)

Prof. Fabiano Cabañas Navarro (Brazil)

Prof. M.Jayananda (India)

Dr Hirokazu Kato (Japan)

Dr Phil Paige-Greene (South Africa)

Dr Brian R. Marker (UK)

HSTG Newsletter no.1 Page 3(15)

HSTG retains its link with IAEG C-10 with the HSTG President also being IAEG C-10 Chair

and several events are prepared and executed in collaboration.

The objectives of HSTG are:

To facilitate formal designation of natural stones that have achieved widespread

recognition in human culture (i.e. heritage stones).

To create the “Global Heritage Stone Resource” (GHSR) as an internationally

recognised heritage stone designation.

To promote the adoption and use of heritage stone designation by international and

national authorities.

At present, there are 222 HSTG correspondents from 50 countries.

3. Recent activities

Activities in 2013

HSTG had a very successful year. It continued in its formative phase with the

organisation of the first Heritage Stone Conference as a session at the General

Assembly of European Geoscience Union (EGU conference) in Vienna, Austria, 7-12

April 2013.

See Table 1 for EGU 2013 contributions. The success of the meeting allowed us to compile a

symposium volume on Heritage Stone, with most contributions presented at the EGU. This

Special Publication of the Geological Society of London has already been published on-line

and a hard copy will be available by mid-2015.

One important outreach activity during the Vienna conference was the interview of the HSTG

Secretary General by the British Broadcasting Commission (BBC) with details of the project

being available to be viewed and read at www.bbc.co.uk/news/science-environment-

22097403 and www.bbc.co.uk/news/science-environment-22102933 .

Our correspondent in Japan Hirokazu Kato proposed at the 48th CCOP Annual

Session that a CCOP Global Stone Heritage Book be compiled and published. The

proposal was warmly received and the meeting recommended Japan to give a proposal

of this issue and to publish a book as the third volume of CCOP Books. The Book

project was approved at the 60th CCOP Steering Committee Meeting in March 2013

in Ubon Ratchathani, Thailand. It was agreed that Dr. Hirokazu Kato, Dr. Yoshihiko

Shimazaki and Dr. Anthony Reedman will serve as Editors of the book. The title of

the book will be "Stone Heritage of East and Southeast Asia" and the content of the

book was tentatively agreed as follows:

A workshop took place the day after our session. 28 people joined the presentation and

following discussion, adding fruitful comments and suggestions for the HSTG management,

activities and other issues related to GHSR. An image of attendees is shown below.

Participants at the IAEG C-10/HSTG workshop in Turin.

Mid conference, a city tour of Turin was arranged to study the local use of building stone. For

this occasion an app had been developed: TOURinSTONES, and can be downloaded from

Google play or Appstore.

A heritage stone session was also organised, 24-25 April 2014, at the North Central

Section meeting of the Geological Society of America in Lincoln, Nebraska under the

title of “Cultural Geology: Capitol Buildings, Heritage Stone, Parks, and more”. There

were nine presentations with Joseph Hannibal and Nelson Shaffer presiding. (See

GSA 2014)

A field trip was also held in association viewing “Building and Ornamental Stones in the

Nebraska State Capital Building”.

The 5th Global Stone Congress was held in Antalya, Turkey, from 22-25 October

2014. Approximately ten papers featured heritage stone in their content. An interim

secretariat for future Global stone congresses was formed and it was decided to

postpone the next event until 2017 in order not to collide with the IGC congress in

Cape Town 2016.

5. Reports from our board members. Reports from everywhere

Lola Pereira in Oxford

In January 2014, Lola Pereira stayed a week in Oxford, while enjoying an Erasmus exchange

at the University of Birmingham. Staying in Oxford allowed her to visit the Natural History

Museum to see the superb collection of dimension stones and the Museum itself, which is

built using different natural stones that serve as an incredible catalogue. Here she wants to

acknowledge the great help of Professor Paul Smith, Director of the Oxford University

Museum of Natural History, and Monica T. Price, Head of Earth Collections at the Museum.

HSTG Newsletter no.1 Page 12(15)

Interior of Museum of Natural History. The court is surrounded by thirty columns, each made

of a different British natural stone.

In addition Lola visited as well the Department of Geography, where Dr Heather Viles

teaches and has a magnificent laboratory for testing industrial rocks. Heather is tutoring two

Marie Curie fellowships at present, both dealing with subjects that have a strong link to the

HSTG interests. At the moment a second visit by Lola Pereira is organized to identify

possible ways of collaboration and joint contributions.

During this same visit, Lola Pereira gave a seminar at the Department of Geography

University of Birmingham, hosted by Dr Mary Thornbush. Mary is a member of the

IAGeoethics, linked to the IUGS. Attendance to the seminar was important in number and in

the profile of participants: many retired members of the Department assisted and were

interested in following HSTG activities. In fact a Master´s student subsequently contacted

Lola Pereira asking for material to complete his Master´s thesis.

Contacts with India

Besides the fluent and friendly connection the HSTG has with India, a new strong link is

being developed with the Stone Technology Center in Ahmedabad. The Director of the Center

Vikram Rastogi has recently showed his interest in a proposal to study serpentinites by the

research group of Lola Pereira at the University of Salamanca. This proposal was sent to the

HSTG Newsletter no.1 Page 13(15)

Spanish Economy Ministry requesting funding and including an Expression-of-Interest letter

from Mr Rastogi, together with other research and institutional correspondence. Furthermore

a Memorandum of Understanding has been signed between the International Stone Research

Centre and the University of Salamanca.

Report from Luis Lopes, Portugal

Luis Lopes was in Mozambique during the Spring of 2014 where he had the chance of

discussing the work of HSTG. He has been promoting the Group during the past couple of

years not only in Mozambique, but also in USA (GSA meeting in Denver), Turkey (Global

Stone in Antalya) and Argentina, at the National Geological Congress where he had been

invited by the organization.

Report from Lidia Catarino, Portugal

The First Meeting European Quarry Landscapes took place, 30- 31 October 2014, in Gran

Hotel Botánicos, Teruel, Aragón, Spain, dedicated to the international cooperation of

recovering historic quarries and landscapes. The meeting was organized by the European

Quarry Landscapes Network. This meeting was part of the LIFE + Programme of the

European Commission, the financial instrument for the environment of the European Union.

European quarries are rich cultural landscapes which also enjoy special natural conditions and

habitats, and rich geological and fossil evidence. Stone use occurs from the beginning of

European art and architecture, and quarries are vital for the conservation of this heritage.

Some quarries have been worked since classical times, providing the stone for Europe’s

greatest buildings and urban settings. Examples of quarries from Austria, France, Germany,

Portugal, Spain (Madrid, Menorca, Salamanca) and UK were presented.

From the Teruel quarries came the clay to make the bricks and tiles to build the 12th century

Mudéjar art of Aragon, now a World Heritage site. Influenced by Islamic traditions and

European Gothic styles, this building tradition is characterized by an extremely refined and

inventive use of bricks and glazed tiles. The quarries of Teruel were visited by the participants

of the meeting guided by the organization and giving all the information about the works in

progress in order to recover the landscape and reuse the place for the citizens of the city.

The panel discussion about the TICCIH Thematic Report on the inscription of quarry

landscapes on the World Heritage List was very fruitful with different opinions. The term

“quarry” was discussed because, in some opinions, quarry landscapes must not be restrictive

to the quarry itself but include other mining aspects. The quarries must be preserved but in

HSTG Newsletter no.1 Page 14(15)

conditions to permit the exploitation if necessary. In some countries (for example Austria) it

is common sense to allow this. In others it is restrictive and there can be interference. Also

some of the quarries are still in operation and must remain operative thus providing people

with work and advantages to the local economy.

The Declaration of Participation and Commitment to the European Network of Quarry

Landscapes was signed by several of the participants with minimal revision.

Report from Hirokazu Kato, Japan

Our Japanese Board member reported on his new situation in retirement from the National

Institute of Advanced Industrial Science and Technology (AIST). He still maintains working

connections to the Institute and works as consultant for OYO corporation. Dr Kato is the

responsible coordinator of a Special Book on natural stones, elaborated after the 48th Annual

Session of CCOP that was held in Langkawi, Malaysia on 5-8 November 2012. It was

organized by the Minerals and Geoscience Department Malaysia (JMG), Ministry of Natural

Resources and Environment (NRE) Malaysia and the Technical Secretariat of CCOP (CCOP

TS) in cooperation with PETRONAS. There were 109 delegates attending the Session from

the following Member Countries - Cambodia, China, Indonesia, Japan, Republic of Korea,

Lao PDR, Malaysia, Papua New Guinea, Philippines, Singapore, Thailand, and Vietnam
