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_576	The oxalate minerals are found in lake bottom sediments layered in Miocene basalt flows along the Columbia River in Oregon. Calcium and oxalic acid originates from fish bones and/or organic sediment. Mineralization occurs in jasper nodules known as "Biggs Jasper." The locality is in the west-central part of the Columbia River Basalt Plateau.
