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: AlAsAuBBaCCaCeCrCuFFeHKMgMoNaNbOPPbSSeSiTaThTiUVYZnZrElements from minerals reported directly at this locality: Structural Groups for minerals in this locality:
Economic ore deposits of the Maybell area are found in the uppermost sandstone unit of the Browns Park Formation. The uranium ore deposits are described as tabular, amoeba-shaped lenses of discontinuous bodies within limited stratigraphic intervals.
In the Maybell area, the Browns Park formation unconformably overlies truncated rocks ranging In age from Precambrian to Eocene, on the north flank of the Axial Basin anticline. The Browns Park formation is dated to be Miocene in age.
