Includes the following sessions:
T30. Geology and fluid dynamics of Cr, Ni-Cu-PGE, and PGE mineralized magmatic plumbing systems
Convenors: Edward Ripley (ripley@indiana.edu), Chusi Li (cli@indiana.edu), Hong Zhong
This session will focus on the geology, geometry, morphology, fluid dynamics, and genesis of mineralized magmatic plumbing systems, with special emphasis on those in the Mid-Continent Rift and Circum-Superior Belt.
T119. Extinction and survival across the Triassic-Jurassic boundary
Convenors: Shane Schoepfer (sschoepfer@wcu.edu), Thomas Algeo (thomas.algeo@uc.edu)
The Triassic-Jurassic boundary represents the first mass extinction experienced by the modern evolutionary fauna. This session will bring together paleontologists, geochemists, and other researchers who are interested in this important period of transition.
T158. Evolution of the Midcontinent Rift: a window into Proterozoic environments, a repository of minerals, and a lesson in rifting
Convenors: Nicholas Swanson-Hysell (swanson-hysell@berkeley.edu), Seth Stein (seth@earth.northwestern.edu), Tyrone Rooney (rooneyt@msu.edu)
The Midcontinent Rift hosts a remarkable record of tectonic, magmatic, and sedimentary processes. Geological, geochemical, geophysical, and geobiological research into the rift is expanding understanding of rift formation, Proterozoic earth history, and its economic deposits.
T174. Permian-Triassic biotic crisis: new insights through integrative studies of earth, ocean and atmosphere
Convenors: Christopher Fielding (cfielding2@unl.edu), Tracy Frank (tfrank2@unl.edu), Steve McLoughlin (steve.mcloughlin@nrm.se), Vivi Vajda (vivi.vajda@nrm.se), Arne Winguth (awinguth@uta.edu)
This session will feature new research on causes and consequences of the Permian-Triassic mass-extinction event, emphasizing work that integrates sedimentological, geochemical, paleontological, and modeling datasets from regions across the globe.
