Main Thrust, Fall 1999
The fall CTG Meeting and Field Trip is currently being planned for Late
October in the Thetford Mines area of Quebec, organized by Alain Tremblay
and Normand Goulet. Details to follow soon on the CTG web page.
Best MSc and PhD theses for 98-99: submission deadline is the end of August.
So far we have only one PhD thesis submitted. Best paper prizes: We currently
scan 7 major journals, and are looking for one or two volunteers to help
expand the number of journals and ease the load. Members are encouraged
to identify papers they think are worthy of consideration, and also to
submit their own work for consideration. (Papers in refereed journals only
please). The CTG would like to compile a list of Canadian papers - this
would be a useful list and would serve as the list of papers considered
for the prize (not every paper published). The CTG needs at least 2 new
councillors, preferably 3, to promote the CTG locally and to consult with
for best paper prize (each assigned a journal); John Waldron has volunteered
to do geology.
Three CTG Sponsorships for
GeoCanada are as follows:
1. Structural Controls on Resources: From Gold to Gas. Covenors: Shoufa
Lin (Waterloo), Sandy Cruden (Univ. of Toronto), Dennis Johnston (Petro-Canada
Oil and Gas) Structural geology is important for resource studies because
structures can control the location, geometry and productivity of both
petroleum and metallic resources. This session will provide a forum for
geologists from industry, academia and the government surveys to discuss
the role of structural geology in resource study and exploration. Emphasis
will be put on structural controls on resources, including structural controls
on emplacement as well as structural modification of the geometry and location
of hydrocarbons and metallic deposits. Both oral and poster presentations
will be considered.
2. Calibrating Earth Processes. Convenors: Kirk Osadetz (GSC), Lisel Currie
(GSC), Paul Renne (Berkeley Geochronology Center) and Sam Bowring (MIT).
The development of a wide range of high precision geochronological tools
gives geoscientists the ability to resolve not only the relative order
of earth processes, but also the rates at which they occur. This symposium
will provide a forum for the presentation of novel geochronological research
relating to the relative and absolute calibration of processes in various
geological environments and at all temperature regimes, as well as the
application of complementary isotope systems and methods for understanding
and enhancing temporal resolution. Researchers are encouraged to submit
results of studies on thermochronology, intercalibration of isotope systems,
high precision geochronology and integration of multiple geochronological
methods.
3. Fluids and Deformation: Processes and Products. Convenors: Glen Stockmal
(GSC), Lori Kennedy (Univ. of B.C.), William Jamison (Upper Crust Inc.).
The presence of fluids in rocks has long been recognized to significantly
affect the nature of deformation. This in turn can have economic significance,
for example transforming a tight carbonate into a potential hydrocarbon
reservoir, or forming conduits for mineralization. This session will focus
on the relationships between fluids and deformation at all crustal levels,
with emphasis on mechanisms and consequences. We welcome new and novel
contributions describing the mechanics of faults and shear zones in the
presence of fluids, the nature of faults and shear zones as seals or conduits,
the influence of fluids on the bulk mechanical properties of rocks, and
insights from geochemical studies, among others. Also the CTG approved
sponsorship of John Waldron and Glenn Stockmal's Port-o-Port fieldtrip
for St. John's 2001. Apparently sponsorship for a Rodinia session has also
been proposed. Send suggestions to Larry Lane and the organizational committee;
proposals will be entertained at the Fall CTG meeting.
A special issue of Tectonophysics on magnetic susceptibility fabrics has
been sponsored by this division (SGTD) of the GAC. The CTG is pleased to
make the following announcement about the "Price Symposium" at Geocanada
2000: IN HONOUR OF THE CAREER OF DR. RAY PRICE, A SYMPOSIUM FOCUSING ON
THE TECTONIC EVOLUTION OF THE CORDILLERA, AND A SEVEN-DAY FIELD TRIP THROUGH
