Precambrian and Mesozoic Plate Margins: Montana, Idaho and Wyoming, with field guides for the 8th International Conference on Basement Tectonics
Sharon Lewis, Richard Berg 1988 Montana Bureau of Mines and Geology Special Publication 96
This volume describes the geology along the routes of two field trips. The papers in the first part of the volume take the reader from the Stillwater Complex across the Beartooth Plateau, to the northern border of Yellowstone National Park, on to the southern Madison Range, and finally to some of the westernmost (probable) Archean exposures in the Highland Mountains south of Butte. The papers in the second part of the volume examine a relatively recent collisional terrane in central Idaho and eastern Oregon. The volume focuses on portions of the Idaho batholith and its enigmatic and fascinating marginal rocks, as well as the heart of the suture zone in the Wallowa-Seven Devils terrane with its group of exotic intrusive, metavolcanic, and metasedimentary rocks.
