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.

W/ 2 main episodes of mineralization "one in early Silurian time and another ending in early Carboniferous time. This suggests, in turn, that mercury was deposited both by the alkali basalt volcanic rocks and by later Hercynian metamorphism or magmatism. The early event remains poorly constrained, although it probably took place shortly after deposition of the ore-hosting Lower Silurian Criadero quartzite"
