Comments on the geologic information

  • Geology (Copied from USDA FS Mine Plan of Operations, Environmental Assessment): The White Banks Mine is hosted in metamorphosed sedimentary rocks on the southwestern flank of Mt. Sopris. Mt. Sopris comprises Eocene-age intrusive igneous rocks (granodiorite) that were intruded into Paleozoic and Mesozoic sedimentary rocks in at least two separate pulses. The igneous rocks are flanked by Mesozoic and Paleozoic sedimentary rocks and unconsolidated Quaternary deposits (glacial, debris flows, colluvium, etc.). Heat from the nearby intrusive activity metamorphosed beds of gypsum, sandstone, shale, and limestone into alabaster, quartzite, hornfels, and marble within the Pennsylvanian-age Eagle Valley Evaporite and overlying Eagle Valley Formation. In the White Banks Mine area, beds of alabaster and marble trend roughly east-west, and dip 20 to 55 degrees to the north (Streufert 2008). The alabaster layer is reportedly 242 feet thick, quartzite is about 77 feet thick, and the marble is about 58 feet thick (Collins 1995). Reported thickness of the marble correlates well with recent measurements of 50 to 60 feet at the surface (R. Taylor, USFS Geologist, personal communication, April 19, 2011). Within the White Banks claims group, the alabaster is the lowermost (oldest) geologic unit mined while brown limestone overlies the alabaster, and black marble overlies the brown limestone (ibid.). Previous underground workings at the White Banks mine have reached the alabaster, but the black marble is not yet exposed.
