“东北寨式”金矿床中雄黄的成因矿物学研究

本文较系统地探讨了“东北寨式”金矿床中雄黄的产状、化学成分、物理性质、晶胞参数、红外光谱与硫同位素组成等特征。雄黄富As亏S、含Sb和微量Au、Ag、Tl、Hg、Bi、Se、Te(Se/Te=29—58);晶胞体积>800;红外吸收340,370cm~(-1);显微硬度平均达57kg/mm~2,δ~(34)S≈-5‰。这些可作为研究区金矿化的标型特征。将其用于对比其它雄黄矿(床)点的研究,预测和评价深部金矿化已获得初步成效。

GENETIC MINERALOGICAL STUDY OF REALGAR FROM THE "DONGBEIZAI-TYPE" GOLD DEPOSITS

Systematically described in this paper is the genetic mineralogy of mineralogy of realgar from the "Dongbeizai-type" gold deposits,involving its natural occurrence, chemical composition, physical properties, unlt-cell parameters, infrared spectrum and sulfur isotopic composition, etc. It is suggested that the realgar high in S but low in As,and containing Sb and trace amounts of Au, Ag, T1, Hg, Bi, Se and Te, with V>800(?)~3, infrared absorption appearing at 340 and 370 cm~(-1),and microhardness=57 kg/mm~2(on average H_v) could be indicative of gold mineralization. Their typomorphic peculiarities have been successively applied to other realgar occurrences for predicting the potential gold mineralization at depth.
