EA10: Global Plate Models: The State of the Art and Future Developments
Dynamic, computer simulations of plate tectonics provide the context for exploring and visualizing Earth's history, focused on deep earth-time reconstructions and processes and on changing palaeoclimate. This session will consider what we have learned since the development of the plate tectonic paradigm 50 years ago; the state of the art; assessing similarities and differences between the various global plate models; key data sets; what we still don't know; and what we don't know we don't know.
EA11: Supercontinent Cyclicity with a Focus on Contributions from Circum-Pacific regions
The plate tectonic paradigm, developed last century, is now recognised to be part of a longer term process which has produced a series of supercratons and supercontinent since at least the Archaean. New research from regions currently situated around the Pacific provide significant contributions to understanding the interplay of major crustal blocks through several supercontinent cycles; contributing to better understanding of regional geology, whole-earth processes and associated mineralization. The session is sponsored by IGCP 648.
EA12: Recent Advances in the Study of Ultramafic Rocks: Anticipating Future Challenges
Ultramafic rocks offer glimpses into the Earth's ~2900 km-thick mantle. This session invites advances in understanding of terrestrial and extra-terrestrial ultramafic rocks including: orthomagmatic and low-T processes, planetary evolution, experimental petrology, mineralization, and geochronology.
EA13: High and Ultra-High Temperature Metamorphism: New Approaches to Kinetics, Models, Geochronology, and Interpretations
The study of high to ultra-high temperature metamorphic rocks has expanded considerably in the recent past, and the kinetics and driving forces for this type of metamorphism are not always well understood. Of particular interest in this session are the interactions and intersections between pressure and temperature in UHT metamorphism, and the implications for methods and approaches when dealing with metamorphism approaching UHT conditions, particularly with respect to thermodynamic modelling and geochronology in UHT terranes.
EA14: Geomicrobiology - Driving Force in Earth History
This session will examine the role of microbes in large-scale changes in the earth's atmosphere, oceans and land mass throughout history.
EA6: Archean Evolution and Ore Deposit Models: Is Plate Tectonics the Key to the Past: A Session to Honour the Career of John Percival
EA7: Proterozoic Crustal Evolution and Metallogeny
This session seeks contributions that shed light on how the Proterozoic tectonic or magmatic processes evolved through time and their links to metallogeny, and vice versa. Although metallogeny is a core theme, we will also consider non-metallogeny contributions of broad interest.
EA8: Resources in Paleozoic Orogenic Belts and Associated Sedimentary Basins: Challenges and Opportunities for Multidisciplinary Tectonics
Sophisticated technology is being increasingly applied to the study of the tectonics and resources of Paleozoic orogenic belts and associated sedimentary basins. This session will emphasize the importance of geological mapping and accurate field-based observations as the underpinning of the technology and as the basis for the interpretation of multidisciplinary geoscience datasets.
EA9: From Continental Shelf to Slope - Mapping the Oceanic Realm
This session will offer multidisciplinary R&D contributions on geology, geophysics, bathymetric and biologic aspects, towards data sampling and acquisition, data analysis and their results, and innovative ways of data access. It also aims to present the development of processes to harmonize and integrate marine data across EEZ boundaries. Digital data sets and maps facilitate international cross-boundary understanding of the Earth and provide the base for future applications such as mapping potential gas hydrate fields as a source for future expoloration or mapping of marine habitats for constructing coastal management systems to keep sustainable marine resources and environments for future generations.
