Projet 648 - Supercontinent Cycles and Global Geodynamics


Projet du PICG - réunion en 2019

  • (1) 12 – 15 May 2019, GAC-MAC-IAH

IGCP 648 will be co-sponsoring special session Pannotia to Pangea: Paleozoic orogenic cycles in the circum-north Atlantic region: A celebration of the career of Damian Nance (SS-GH18).

More information can be found on the conference special session website.

  • (2) 22 June – 6 Jul. 2019, IGCP648 - Field Symposium

Madagascar has been the scene of much discussion and new research over the last two decades by a wide group of international authors. It is a spectacular country in terms of hospitable people, amazing scenery, flora and fauna and incredible geology. The symposium will include ten days of field trip followed by two days of conference.

The provisional program is:

-June 22, 2019, Arrival at Antananarivo.

-Jun. 23, – Jul. 2, 2019, Pre-conference field trip.

-Jul. 3, 2019, Networking and poster session.

-Jul. 4, 2019 – Jul. 5, 2019, Conference in Ifaty.

-Jul. 6, 2019, Bus back to Antananarivo.

  • (3) 9 – 13 Dec. 2019, AGU Fall Meeting 2019

IGCP 648 have a dedicated session (session 74486 - The tectonics and geodynamics of supercontinents) at the upcoming AGU Fall Meeting in San Francisco. More details can be found at https://www2.agu.org/Fall-Meeting

 

 

 

Bref résumé du projet

Rapid recent progress in supercontinent research indicates that Earth's history has beendominated 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.
