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.

Locality Notes from all Ages at Locality:

Age ID	Locality Notes
Jen_0000616	MAGMATIC STYLE: Central, sub-volcanic sövite intrusion of about 1 km2, numerous alvikite dykes and lapillistone layers (at two localities) 1-1.5 m thick. Lapilli generally from 0.5 to 15 mm but small bombs reach a few centimetres. ASSOCIATED SILICATE ROCKS: Lavas and tuffs include limburgite, nephelinite, phonolite and leucite tephrite; dykes and larger intrusive bodies include shonkinite, bergalite, phonolite, monchiquite, essexite and theralite.
