Journal Article
Published: 01 February 1982
American Mineralogist (1982) 67 (1-2): 132–136.
...Akihiko Okada; Klaus Keil Abstract Caswellsilverite, NaCrS 2 , occurs in the Norton County enstatite achondrite as anhedral grains up to 1 mm in size. It is associated with daubréelite, titanoan troilite, ferromagnesian alabandite, oldhamite, kamacite, perryite, and a dark-gray phase, also a new Na...
