Oblique. Isomorphous with epidote. m 100, t ooi, u 012, / 103, o no, y 112. Fracture uneven. Opaque. Lustre vitreous. Dark brown, black. Streak grey. 11 = O’O. a = 3-805 (from Laach). Before the blowpipe melts with intumescence into a bright, black, magnetic slag, which, when the intumescence ceases,^ becomes very infusible. With Fluxes yields the reaction of iron. Is supposed to be Fe s S J + 2-FS. Is found in small crystals in the Neskiel mine at Arendal, in rhyacolite in volcanic rocks at the lake of Laach, and in granite at Werchoturje in Siberia. 174.
