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.
This mineral is using an age reported as an element mineralization period.
O
This mineral is using an age calculated from all data at the locality.
R
The age displayed for this mineral originates from a different, non-child locality.
P
The age displayed for this mineral is the range of ages for this mineral at all of this locality's children.
This mineral's age has not yet been recorded.
This Mineral list contains entries from this locality, including sub-localities. Minerals in bold are reported by mindat.org as occurring directly at this locality, and do not occur at any children (sublocalities) of this locality.Elements at this locality, including sub-localities: AlAsBaCCaCdClCuFFeHKMgMoNaOPbSSeSiSrUVZnElements from minerals reported directly at this locality: Structural Groups for minerals in this locality:

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.

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.
Uranium ore is found in the bottom portion of the Moss Back member of the Triassic Chinle Formation. The Moss Back member belongs to the upper Late Carnian substage.
