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: AlBBaCCaClCrFeHKMgMnNaNiOPSSiTiElements from minerals reported directly at this locality: B C H Na O S Structural Groups for minerals in this locality:
This sample is from site 2d, moraine material. Saline minerals occur in four settings of two localities in the Lewis Cliff area.
Michelle_513
This sample is from site 2c. This sample was from the margin of a supraglacial pond. Saline minerals occur in four settings of two localities in the Lewis Cliff area.
Michelle_535
This sample is from site 1, large mounded deposits, englacially entrained in a moraine field. Saline minerals occur in four settings of two localities in the Lewis Cliff area.
Michelle_536
This sample is from site 2a, englacially entrained in dust band-like geometry. Saline minerals occur in four settings of two localities in the Lewis Cliff area.
Michelle_537
This sample is from site 2b, englacially entrained in dust band-like geometry. Saline minerals occur in four settings of two localities in the Lewis Cliff area.
Michelle_538
This sample is from site 2d, moraine material. Saline minerals occur in four settings of two localities in the Lewis Cliff area.
Age of nahcolite matrix from site 2d. Age of U series dating disagrees with C14 results. Author believes the ~150k to be a more reliable estimate of the nahcolite matrix. This age is older than what was found with englacially entrained samples.
