Important Update News
The RRUFF Project 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. Existing RRUFF.info links will resolve to the new site after RRUFF.net is officially released.
We are grateful to NASA for the funding of this effort.

Name: Fettelite RRUFF ID: R100083 Ideal Chemistry: [Ag6As2S7][Ag10HgAs2S8] Locality: Chanarcillo, Chile Source: William W Pinch [view label] Owner: RRUFF Description: Red platy crystals on acanthite. Cell parameters match those reported by Bindi et al (2009), indicating a fettelite polytype. Status: The identification of this mineral is confirmed by single-crystal X-ray diffraction and chemical analysis. |
