It is a thiospinel, the Mn analog of daubr\u00e9elite (Fe2+Cr2S4), and a new member of the linnaeite group. Tiny grains of joegoldsteinite were also identified in the Indarch EH4 enstatite chondrite. The chemical composition of the Social Circle sample determined by electron microprobe is (wt%) S 44.3, Cr 36.2, Mn 15.8, Fe 4.5, Ni 0.09, Cu 0.08, total 101.0, giving rise to an empirical formula of (Mn0.82Fe0.23)Cr1.99S3.95. The crystal structure, determined by electron backscattered diffraction, is a Fd3m spinel-type structure with a = 10.11 \u00c5, V = 1033.4 \u00c53, and Z = 8.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Junko Isa, Chi Ma, Alan E.
