| Michelle_577 | Radon Mine is in Big Indian District of San Juan County, Utah. It is a former uranium mine with an occurrence of whewellite and celestite in vuggy openings along the "Radon" fault. At this fault, the Chinle is composed of interbedded lenses of medium-grained sandstone, fine-grained sandstone, mudstone, and claystone. The "carbonaceous trash" found in the lower part of the Chinle Formation likely provided the oxalic acid required for the formation of the whewellite. |

(1960) | AM45_1257 | Whewellite is associated with the "carbonaceous trash" found in the Triassic Chinle Formation. The author estimates the paragenesis from oldest to youngest is celestite, pyrite/marcasite, asphaltic material, whewellite, calcite, strontianite. Some of the asphaltic material is intergrown with the whewellite. | ||||||||||
