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: Pyroxene RRUFF ID: R110130 Ideal Chemistry: Locality: Little Deer Creek eclogite, Skagit County, Washington, USA Source: Bart Cannon [view label] Owner: RRUFF Description: Blocky transparent green crystals coating a surface of a rock. Single crystal X-ray diffraction shows that this sample is composed of exsolution lamellae of diopside and jadeite Status: The identification of this mineral has been confirmed only by single crystal X-ray diffraction. |
