Listvenit s výskytem minerálu gersdorffit-kobaltinové řady v lomu Dřínová u Tišnova (Morava)
Roč.31,č.1-2(2024)
Chromian illite-magnesite-dolomite-quartz rock (listvenite-like) containing Ni-Co mineralization was found in the Svratka orthogneisses from the Dřínová quarry. The main rock-forming minerals are Fe-rich magnesite, Fe-rich dolomite, Cr-illite and quartz, less frequently calcite. Accessory minerals include chromite (with 0.841–0.886 apfu Fe2+ and 1.642–1.742 apfu Cr), gersdorffite-cobaltite (Ni0.45-0.92Fe0.01-0.34Co0.01-0.34As0.83-1.02Sb0.00-0.03S1), sulfides (pyrite, sphalerite), and apatite. The illite from the Dřínová quarry contains up to 3 wt. % of Cr2O3. Presence of the Cr-illite, accesory chromite, and Ni-Co sulfoarsenides represents origin from ultrabasic protolith, reflecting transformation to phyllosilicatecarbonate-
quartz listvenite.
