雄黄是马脑壳大型超微细金矿床中的重要载金矿物，本文对其地质产状、光学物理性质、化学成分及晶体结构等进行了初步研究。研究结果表明，本区雄黄属低温β－雄黄变体，具有亏Ａｓ、含Ｓｂ、Ｆｅ、Ｈｇ、Ａｕ、Ａｇ及晶胞参数较普通雄黄普遍增大等特点。晶胞参数：ａ０＝９．３５７（３）Ａ，ｂ０＝１３．５８１（４）Ａ，ｃ０＝６．６１３（３）Ａ，β＝１０６°３４′（２），Ｖ０＝８０５．５１（３７）Ａ３。据此，探讨了雄黄晶体中非主量元素的可能存在形式及其找矿意义。
Realgar is an important gold-bearing mineral in a large-scale superfine gold deposit in the horse’s head. In this paper, the geological properties, optical physical properties, chemical composition and crystal structure of realgar are studied. The results showed that the low-temperature β-androgens of realgar in this region had the characteristics of As, Sb, Fe, Hg, Au and Ag, and their unit cell parameters were generally higher than those of common realgar. The cell parameters are: a0 = 9.357 (3) A, b0 = 13.581 (4) A, c0 = 6.613 (3) A, β = 106 ° 34 ’(2), V0 = 805.51 ( 37) A3. Based on this, the possible forms of non-major elements in realgar crystals and the significance of their prospecting are discussed.
