This fault has acted as the primary hydrothermal channel way for the rising copperbearing fluids that produced the deposits. Bleached sandstones of the Cretaceous Burro Canyon Formation host the typical Lisbon Valley copper ore body, with subsidiary mineralization in the overlying Dakota Sandstone.Golden Valley Formation (Eocene and Paleocene) at surface, covers 0.7 % of this area. Upper member: yellowish-brown micaceous sandstone, sand, silt, and clay; fluvial sediment; as thick as 60 metres (200 feet). Lower member: white or yellow clay, silt, and sand; a weathering zone developed on underlying unit; as thick as 20 metres (65 feet).The Dakota Sandstone rocks also contain coal, indicating that swamps were present. The contact between Dakota Sandstone and the Jurassic stratigraphic units is a clear change between the gray and brown Dakota rocks to the white and red Jurassic rocks, and a clear erosional surface separates the two.
