| Abstract;Lindgrenite, Cu3(MoO4)2(OH)2, was found in a dump at the Sansei mine, Nara Prefecture, Japan. It occurred as aggregates of thin platy crystals up to 3mm wide in veinlets in quartz, and as a mono-mineral or in association with limonite, chrysocolla and malachite. It was yellowish green with a greasy luster in hand specimen. The Vickers microhardness was 351kg mm-2 (25g load) and the density was 4.24g cm-3. The empirical formula of the mineral was Cu2.98Mo2.01O8,05(OH)1.95 on the basis of O=10. The unit cell parameters were a=5.620(1), b=14.043(2), c=5.041(1) .ANGS., and .BETA.=98.49(1).DEG.. It is likely that lindgrenite at the Sansei mine was formed as a secondary mineral in solutions dissolved from bornite and molybdenite. (author abst.) |
