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: AgAlAsAuBBaBiCCaClCoCuFFeHHgKMgMnMoNNaNiOPPbPdPtReRhSSiSnTeTiZnElements from minerals reported directly at this locality: Al O Si Structural Groups for minerals in this locality:
Basal Ni-Cu sulfides in mafic-ultramafic intrusion

A guano and fossil rich cave in the dolomitic hills of Gcwihaba Valley. Fossils indicate heavy sedimentation at the Plio-Pleistocene boundary, with ongoing spleothem mineralization.

See Table. 1 Global resources of nickel metal and ages of the major nickel sulfide deposits of the world. Age can refer to the age of a specific nickel sulfide deposit, or the general age of the metallogenic province containing nickel deposits that are similar to a dated deposit (e.g. 2705 Ma Komatiite-hosted deposits in the Eastern Goldfields Province).
At the time of ancient cavern formation, the water table lay about 30 metres higher than the present datum in the floor of the Gcwihabadum. The fauna indicated an age for the sediments of about 2.5 million years. Thus considerable erosion can be postulated to have occurred in the region since the end of the Pliocene.
