Mineral Evolution Database
Created and maintained by the Mineral Evolution Project in partnership with RRUFF and mindat.
Mineral locality data provided by mindat.org



The Mineral Evolution database is currently under development.

The goal of this page is to present localities at which the mineral is found, and estimates of the oldest possible geologic age of the minerals at these localities.

Michelle_577Radon 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.

Michelle_577252201Triassic Age of mineralization in the Chinle Formation    Calcite, Celestine, Marcasite, Pyrite, Strontianite, Whewellite 38512Radon Mine, Big Indian District (Big Indian Wash - Lisbon Valley Area), San Juan Co., Utah, USARadon MineGude et al. (1960) AM45_1257Whewellite 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.
