| 説明 | This small, abandoned copper mine is in Salina Canyon, Utah. The ceilings and walls are horizontal sedimentary rocks. The floor of the mine corresponds to an angular unconformity - vertically-oriented rocks occur below. Copper-rich fluids once moved along the erosion surface and patchily mineralized adjacent rocks. Green malachite and blue azurite can be seen in many places.Stratigraphy: Flagstaff Formation, mid-PaleoceneLocality: Salina Canyon, Sevier County, central Utah, USA |
