福島県水引鉱山産エリー石 <Bull. Natn. Sci. Mus., Tokyo>Elyite from the Mizuhiki Mine, Fukushima Prefecture, Japan

Abstract

Elyite from the Mizuhiki mine, Fukushima Prefecture, is found as fibrous crystal groups in tiny vugs of limonitic ore coposed of supergene galena and chalcopyrite. This is the first occurrence of this mineral in Japan. The averaged chemical analysis by EPMA gave PBO 80.49 CuO 6.71,SO_3 7.70,H_2O (by difference) 5.10wt%, yielding the empirical formula Pb_<3.99>Cu_<0.94> (SO_4)_<1.07> [O_<0.73>(OH)_<6.28>]_<7.01> on the basis of total cations=6 in anhydrous part. The X-ray single crystal study indicated elyite to be monoclinic P2_1/c with a=14.244(1), b=11.536(1), c=14.656(1)A, β=100.45(1)°.
