GeoCanada 2000
Calgary, Alberta, Canada
May 29 - June 2, 2000
Thematic Session 28

Title:
Recent Advances in Earth and Planetary Sciences by Isotope Ratio Mass
Spectrometry

Convenors:
I. E. Hutcheon (University of Calgary)
B. Mayer (University of Calgary)
C. Viau (Encal Energy Ltd., Calgary)


Dear colleagues:

This is a call for papers for a symposium to celebrate the contributions of
Professor H. Roy Krouse to earth and planetary sciences. We plan a session
featuring invited and contributed papers as well as poster presentations at
GeoCanada 2000 (see http://www.geocanada2000.com). This Millennium
Geoscience Summit, to be held from May 29 to June 2, 2000 in Calgary
(Canada), is the first joint meeting of the Geological Association of
Canada, the Mineralogical Association of Canada, the Canadian Society of
Petroleum Geologists, the Canadian Society of Exploration Geophysicists, the
Canadian Well Logging Society, and the Canadian Geophysical Union. The
philosophy of this meeting is to bridge the disciplines of these different
groups, and we can think of no better opportunity to recognize the many and
varied contributions of Professor H. Roy Krouse to earth and planetary
sciences. Working across disciplines, using isotopic measurements to solve
problems both scientific and technical, are the hallmark of stable isotope
research in Professor Krouse's laboratory at the University of Calgary. We
cordially invite you to submit an abstract for this symposium (a short
description of the session is given at the end of this message).

Abstracts can be up to four pages in length with embedded graphics.
Submissions will be accepted until January 7, 2000.  Further details on
preparation and submission of abstract can be found at:

If you submit an abstract for this session, send it to the organizers of
GeoCanada 2000 (instructions at address above), but don't forget to send a
copy to us, either as an attached file or by mail. If you have any further
questions or concerns, contact us at the address below, but do not reply to
the list!

Short Description of Thematic Session #28:

Isotope Ratio Mass Spectrometry (IRMS) is frequently used to study the earth
and the solar system. Stable isotope techniques have provided new insights
into the composition of the earth's interior, meteorites, and distant stars,
enhancing our knowledge of the history of the universe. They have also shed
light on the major biogeochemical cycles within the earth's fragile
envelope, comprised of the atmosphere, biosphere, hydrosphere, and
lithosphere. Isotope ratio mass spectrometry has facilitated many scientific
breakthroughs, which would have been impossible with other techniques, in
the study of all parts of the earth and solar system.

This session is organized in recognition of the contributions of H. R.
Krouse to earth and planetary science. As a physicist, Dr. Krouse has been
instrumental in the development and improvement of isotope ratio mass
spectrometers for more than three decades. More importantly, he has
successfully applied stable isotope measurements to the study of many
phenomena in economic geology, oil and gas exploration and processing,
geochemistry, hydrology, glaciology, environmental sciences, archaeology,
medicine, space science, and numerous other disciplines.

The intent of this session is to bring together a wide variety of scientists
from different disciplines with research interests in isotope ratio mass
spectrometry. We solicit papers describing significant advances or
breakthroughs in a field of earth or planetary sciences, which have been
facilitated by the use of stable isotope techniques. Interdisciplinary
topics are particularly welcome.
