Supercontinent Cycles & Global Geodynamics
- 2015 AGU–GACMAC Joint Assembly, Montreal, Canada, 3-7 May 2015
Session Number and Title: PG22A: Precambrian Craton Reconstructions, Geodynamics, and Paleoenvironments
We will launch IGCP648 at this meeting.Joint Assembly Website
- IGCP 648 First Field Symposium: Supercontinent Cycles and Global Geodynamics, Hawaii, 10-12 December, 2015
We plan a two-day conference to cover all aspects of the project; with a large gathering of geodynamic modelers who will interact with the supercontinent community during the conference. There would be half-day group sessions on geodynamic modeling and database construction. This conference would be followed by a one-day field excursion to examine the active oceanic hotspot that is located above the Pacific Large Low Shear Velocity Provinces (LLSVPs). Members will be able to fly to San Francisco on 13 December to join the AGU Fall Meeting.
A small number of partial financial supports will be made available from the IGCP project fund to support the participation of students and members from less developed countries.
Rapid recent progress in supercontinent research indicates that Earth's history has been dominated by cycles of supercontinent assembly and breakup. New developments in geophysical imaging power and computer simulation have provided increasingly clearer views of the Earth's interior, and how the moving plates on the Earth's surface interact with the deep planetary interior. In this project, we will bring together a diverse range of geoscience expertise to harness these breakthroughs in order to explore the occurrence and evolution history of supercontinents through time, and the underlying geodynamic processes. As part of this project, we will establish/improve global databases of geotectonics, palaeomagnetism, mineral deposits, and the occurrences of past mantle plume events, and examine how the supercontinent cycles interacted with the deep mantle to produce episodic and unevenly distributed Earth resources. The project builds on the success of a series of previous IGCP projects. It will not only lead to major scientific breakthroughs, but also develop user-friendly GIS-based databases that can be used by anyone who wants to reconstruct palaeogeography, test geodynamic models, model major climatic events such as Snowball Earth events, and predict exploration targets for Earth resources. discovery of new Earth resources.
