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.

Giersdorf_00000855All of these pegmatites are hosted by high-grade sillimanite- and garnet-bearing mica schists belonging to the crystalline basement of the Southern Alps. The dikes consist of albite + quartz pegmatite with almandine, schorl, and muscovite as common accessories. These pegmatites can be classified as the beryl-columbite-phosphate subtype in the classification of Černý & Ercit (2005).
