Mesoproterozoic Belt Basin

Mesoproterozoic Belt Basin

The UM Geosciences program has continued important work in the world-renowned Mesoproterozoic Belt Basin of the Northern Rockies, with the upcoming publication of Special Paper 522 of the Geological Society of America. The book, "Belt Basin: Window to Mesoproterozoic Earth", edited by UM alum Dr. John MacLean, and UM Professor Jim Sears, features 14 chapters contributed by 36 geoscientists from around the world with research interests in the Belt Basin. The topics range from sedimentology and stratigraphy to structure, tectonics, and mineralogy.  The book evolved from "Belt Symposium V", a field conference held in Salmon, Idaho, in 2013. Belt symposia are held once every decade. We dedicated the book to long-time Belt sedimentologist and UM emeritus professor Don Winston, the only researcher to have presented at each of the five conferences.

 In conjunction with the publication, Sears, MacLean, and UM Geosciences alum Stuart Parker organized a Geological Society of America sponsored field trip across Glacier National Park to examine the eastern edge of the Belt Basin and the Lewis thrust fault. Sears and MacLean also chaired a Topical Session on the "Structure and Tectonics of Mesoproterozoic Basins" for the 2016 Annual Meeting of the Geological Society of America.
