Includes the following session:

Roles of mantle plumes/superplumes in supercontinent evolution

Convenors: Y. Xu (yigangxu@gig.ac.cn), K. Condie (kcondie@nmt.edu)

This session will focus on mantle plumes and large mantle upwellings and their role in the supercontinent cycle. Topics will include, but are not restricted to, 1) the role of descending slabs in generating mantle plumes in the D” layer; 2) geophysical models of mantle plume events through time and their relation to supercontinent formation and breakup; 3) the geologic record of mantle plume activity through time; 4) comparison of LIP and continental crust age spectra through time; 5) LIPs (including LIP-type greenstones) and their relation to mantle plumes through time; and 6) weak plumes and strong plumes: origin, source and possible role in supercontinent breakups. We encourage presentation of controversial papers that will generate lively discussion.
