Important Update News
The RRUFF Project (rruff.info) is being updated to improve its interface and content. The beta version of the update is accessible to the public at RRUFF.net. New data is only being added to the beta site. Please note that it is in development, and some components are not functional.
We are grateful to NASA for the funding of this effort.

Name: Roscherite RRUFF ID: R070308 Ideal Chemistry: Ca2Mn2+5Be4(PO4)6(OH)4·6H2O Locality: Black Mountain Quarry, Rumford, Oxford County, Maine, USA Source: James Shigley [view label] Owner: RRUFF Description: Reddish brown prismatic crystals associated with white albite. The color is a thin coating of something. Based on cell parameters, we cannot exclude greifensteinite as the identification, without chemical analysis. Status: The identification of this mineral has been confirmed only by single crystal X-ray diffraction. |
