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.

Age ID	Locality Notes
Michelle_372	Gollapalle (CC-4) is of the Chigicherla cluster in the Warjrakarur Kimberlite Field. Emplaced in basement granitoids, it is a circular body of hard melanocratic and greenish black material. Weathered, carbonated and clay rich variety occurs here as well.
Michelle_373	Gollapalle (CC-5) is of the Chigicherla cluster in the Warjrakarur Kimberlite Field. Narrow pear shaped body emplaced into basement granitoid rocks. Crustal granitoid xenoliths are common with an abundance of kimberlite melt in melt segregations that give the appearance of a conglomerate.
Michelle_374	Gollapalle (CC-5) is of the Chigicherla cluster in the Warjrakarur Kimberlite Field. Narrow pear shaped body emplaced into basement granitoid rocks. Crustal granitoid xenoliths are common with an abundance of kimberlite melt in melt segregations that give the appearance of a conglomerate.
