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.

Dating ofvo1canic rocks in central and southern Finland have also yielded U-Pb zircon ages of 1.87-1.90 Ga (Ah o 1979; Helovuori 1979; Patchett and Kouvo 1986; Welin 1987). This indicates that deposition of vo1canic rocks occurred over a time interval of about 30 M yrs in the central part of the Baltic Shield.
