We are on the brink of a revolution in understanding orogenesis, the timing and trajectory of crustal growth and the nature of related lithospheric and deeper mantle processes. We have 21st century tools to apply to an Earth System approach to probe the workings of our planet through time. These include: advances in geochemical analysis technology, geochronology methodologies, and experimental capabilities that are yielding extensive new datasets; global and regional geophysical datasets; and computer modelling power to apply to tectonic and geodynamic modelling. Integrating these different datasets will enable unprecedented imaging and modelling of the effects of different orogenic processes from the Archean to the present day.

This session aims to: (1) explore the impact of such recent advances relevant to accretionary, collisional and intracratonic processes by big data analysis of geophysical properties, petrology, geochronology/isotope/element distribution geochemistry, and petrology, (2) explore possible differences in crustal formation, architecture and preservation between accretionary and collisional orogens; and (3) to better understand the role of orogenic provinces in shaping the surface and resource availability of our planet Earth.
