Session 8: Lithospheric architecture, deep earth material probing, and metallogenesis Co-Conveners: WANG Tao (SinoProbe Lab. and Institute of Geology, CAGS, China), HOU Zengqian (SinoProbe Lab., China), SELTMANN, Reimar (The Natural History Museum, UK), COLLINS William (Curtin University, Australia), KUSKY Timothy (China University of Geosciences, Wuhan, China)，SAFONOVA Inna (Southwest Jiaotong University, Chengdu, China) Description: One of the important tasks of solid-Earth science is to investigate deep crustal and whole lithosphere architecture, pathways and processes that create large-scale mineralization. Lithospheric (magmas and rock) probes and isotopic mapping (such as whole-rock Nd, zircon Hf) provide powerful datasets that can be used to interpret abundant geophysical data for these deep regions and to define their thermochemical structure that can inform energy-and mineral-exploration strategies. This session is focused on: (1) Continental growth and three-dimensional deep Lithospheric architecture from 3D to 4D; (2) Ore systems, their timing and location as related to lithospheric architecture and tectonic environment; and (3) Integration of petrology, geochemical, and geophysical datasets in constructing 3D-4D Lithospheric architecture and a predictive model for metallogenesis through time. Case studies on regional crustal and underlying mantle architecture, deep-lithosphere geochemical fingerprints, and regional metallogenesis are also welcome.
