Project 648 - Supercontinent Cycles and Global Geodynamics

IGCP Project meeting in 2017

Rodinia 2017

  • 11-14 June 2017, Townsville, Queensland, Australia

Rodinia 2017 will bring together geoscience expertise to present and discuss the latest progress in the occurrence and evolution history of supercontinents through geological time, to highlight the latest developments in the geodynamics of supercontinents, and developments in the relationships between supercontinents and other geological phenomena including updates in the global databases of geotectonics, palaeomagnetism, mineral deposits, and the occurrences of past mantle plume events. We will examine the link between supercontinent cycles and the deep mantle.

Rodinia 2017 welcomes contributions from all geoscientific fields related to supercontinents from all geological eras. The meeting will be hosted in Townsville, Queensland, Australia and will be followed by a postconference field trip across the Mount Isa terrane, which is one of the most spectacularly preserved Paleoproterozoic terranes on Earth that holds clues about the configuration and evolution of supercontinents Nuna (Columbia) and Rodinia.

Brief outline of the project

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.
