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.

	CRG336_1255-001	39	36	39-36	?-?	age of hydrothermal mineralization					Yes				11294	La Gardette Mine, Le Bourg-d'Oisans, Isère, Auvergne-Rhône-Alpes, France	La Gardette	Feybesse et al. (2004)	10.1016/j.crte.2004.06.009	CRG336_1255	The age for this deposit was derived from the age of mineralization the nearby Bourg-d’Oisans area ~ 5km south of Allemont (Allemond). Specifically the age of hydrothermal mineralization at La Gardette. There is no scientific liturature on the Les Chalanches Mine in Allemont, or on mineralization in the Allemont. So, the age of the deposit at La Gardette ~ 5km south of Allemont will be used. 39-36 Ma. The mercury at Allemont is associated with silver.
