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
Jen_0000669	MAGMATIC STYLE: Radiating dykes up to 6 km in length but only 2-25 cm thick. Possible lapilli in central breccias. Also numerous carbonatitic and kimberlitic vents. ASSOCIATED SILICATE ROCKS: Central area of tuffs/microbreccias of rock and mineral fragments cemented by carbonate that have probably been fenitized. Vent of monticellite-nepheline peridotite and aillikite.
