Abstract

Caswellsilverite is yellowish grey to light grey in reflected light and has strong bireflectance and anisotropism. Microprobe analysis gave NaCrS (sub 2) with minor Ti and Mn. The NaHF (sub 2) type of structure is R3m with a 3.55, c 19.5 A on a hexagonal unit cell. The strongest XRD lines are 2.60(10), 2.07(8), 1.910(8), 1.779(8), 6.49(7), 1.465(6), 1.134(6) A. It occurs associated with daubreelite, troilite, alabandite, oldhamite, kamacite, perryite and a new Na-Cr sulphide (with 13%H (sub 2) O) in the Norton County enstatite achondrite.
