Butte Mining and Mineral Symposium 2018
I've just returned from another trip to my field area, Butte, America. I went to give a talk on a portion of my research on quartz vein formation, and also ended up meeting an awesome community of Montana geoscientists and rockhounds.
The Atlantic Cable Lode Gold deposit (Cable Mine, Deer Lodge, MT) is a skarn deposit created by the intrusion of a granodiorite into the marmorized Upper Cambrian Hasmark dolostone. Mineralization occurs as veins in a shear zone with replacement-type mineralization proximal to the fracture network.
