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.

Michelle_564	Whewellite is found in association with Westphalian age freshwater sediments of the Kladno Coal Basin. Large whewellite crystals are found on dislocations of girdles or on cracks in basal breccia resting on Proterozoic basement. Whewellite has not been found directly in the coal beds.
