New data on rasvumite and djerfisherite

Electron microprobe analyses and X-ray diffraction studies have shown the identity of ras-vumite from a new occurrence at Coyote Peak, Humboldt County, California, and holotype material from the Khibina massi-f, Kola Peninsula, USSR.

Description
Summary:Electron microprobe analyses and X-ray diffraction studies have shown the identity of ras-vumite from a new occurrence at Coyote Peak, Humboldt County, California, and holotype material from the Khibina massi-f, Kola Peninsula, USSR. The electron microprobe analyses have established that the correct formula is KFe2S3 instead of K3FeeS,a, as originally pro-posed. We compare new electron microprobe analyses of djerfisherite from the two localities and show that these djerflsherites do not contain magneslum.
