摘要

ullmanite - gersdorffite固溶体矿物是在捷克共和国波希米亚中部Příbram (Černojamské矿床)Lill矿的排土场材料中发现的。它形成直径达0.5毫米的灰色自形晶体群，在针勒石晶体上具有金属光泽。它具有强烈的化学分带性，从富砷的乌氏锰矿到含可变Sb含量的格氏锰矿。其单位胞参数为5.7728(13)Å和v192.37 (7) Å3，由单晶x射线数据得到。其中发现了长达4 mm的针状千闪石晶体群，分子式为(Ni0.97Co0.03)Σ1.00S1.01，以及非常罕见的长达80 μm，分子式为Co1.00(Ni1.66Co0.24Fe0.02)Σ1.92S4.09。

Minerály řady ullmannit - gersdorffit v asociaci s milleritem z haldy dolu Lill v Příbrami (Česká republika)

Minerals of the ullmannite–gersdorffite solid-solution was found at mine dump material from the Lill mine, the Černojamské ore deposit, Příbram, central Bohemia, Czech Republic. It forms grey groups of idiomorphic crystals up to 0.5 mm across with metallic luster on millerite crystals. It is strongly chemically zoned, from As-rich ullmannite to gersdorffite with variable Sb contents. Its unit-cell parameter, a 5.7728(13) Å and V 192.37(7) Å3, was refined from single-crystal X-ray data. Groups of acicular millerite crystals up to 4 mm in length and formula (Ni0.97Co0.03)Σ1.00S1.01 and very rare siegenite grains up to 80 μm and formula Co1.00(Ni1.66Co0.24Fe0.02)Σ1.92S4.09 were found in association.
