Special Sessions of GAC/MAC Annual Meetings

RFG 2018 logo

The Geological Association of Canada`s Volcanology and Igneous Petrology (VIP) Division is sponsoring the following Session at the upcoming GAC-MAC meeting in which will be held in Vancouver as part of the RFG meeting in June, 2018.

Sessions that might be of interest include:

EA36: Igneous Processes and Climate Change Over All of Earth History Volcanism and igneous activity have led to weather and climate change on time scales ranging from billions of years to hours. With recent climate change impacting the destiny of our planet, petrologists have important contributions to make in understanding how Earth's climate is evolving. This session welcomes presentations on how igneous activity created Earth's earliest environments through to how historical eruptions impacted weather and climate.

EA37: Minerals as Archives of P-T-X and Time This session brings together researchers working on the full breadth of methods used to reconstruct chemical and physical conditions from minerals and their timing, in nature, as well as in anthropogenic settings.

EA38: Current Concepts in Igneous and Metamorphic Petrology Petrology is the underpinning of earth science, and the application of current sophisticated technology to the study of igneous and metamorphic rocks has transformed our understanding of earth systems. This session welcomes contributions on any aspect of igneous and/or metamorphic petrology and their role in modern interpretations of local, regional, or global geology.

MIN24: Stable and Radiogenic Isotope Systems: Applications in Exploration and the Environment 
Modern analytical technology has substantially reduced the cost of isotopic analysis to the level of routine analysis, in addition new systems have become commercially viable and the knowledge base and understanding of a range of isotope systems is now well documented. This session will demystify the application of isotopes in exploration and the environment through solid case studies demonstrating their value add benefit integrated with other information in the decision process.

MIN10: The Middle and Lower Yangtze Valley Iron Oxide-Apatite-Porphyry-Skarn Province, China: Characteristics and Global Comparisons 
There is considerable research being undertaken on the origins of IOCG and Fe-deposits both in terms of understanding their formation and the possible paragenetic links between the two. This session will explore the nature of this style of mineralization in China. The deposits of the MLYB have recently been the subject of intense study and debate with considerable discussion as to their classification and origin, both topics that will be explored in this session as well as comparing these deposits to similar systems around the world, particularly those of Chile.

MIN11: Multi-Commodity, Multi-Scale Exploration Targeting Using the Large Igneous Province Record 
The Large Igneous Province (LIP) record is becoming important as a tool in exploration targeting for a wide range of commodities and at regional to local scales. Presentations are welcome on all aspects of LIPs (and associated silicic, carbonatite and kimberlite magmatism) that can contribute to exploration targeting.

MIN7: Magmatic Arc Fertility and the Genesis of Porphyry Cu-Mo-Au Deposits 
Porphyry Cu-Mo-Au deposits are large, low grade orebodies formed in the shallow crust by magmatic-hydrothermal processes mostly operating in convergent plate margin settings. Despite the relative abundance of magmatic arcs in the geological record, most are poorly endowed with porphyry deposits. This session will investigate processes that potentially increase the favourability of an arc for generating large porphyry deposits. Studies of arc evolution and related porphyry formation using a variety of field, analytical, and experimental methods on fluids, melts and rocks are invited.
