Usually occurs in basaltic volcanics, metapyroxenite, also with augite in limburgite. |
Approved IMA 1998 (Dana # Added) |
Found in drill core from Haselborn, near Ilbeshausen, Vogelsberg, Hessen, Germany. Link to MinDat.org Location Data. |
Named after Barthelemy Faujas de Saint Fond (1741-1819), French geologist and writer on the origin of volcanoes. The Ca-dominant member of the faujasite series. |
