摘　　要：作者通过野外和室内研究于 1991年首次提出荒沟山金矿床为典型岩溶矿床 .该矿床产于下元古界老岭群珍珠门组白云石大理岩与花山组片岩接触带大理岩一侧 .矿体呈穹状、管状、漏斗状等形态 .矿石由岩溶洞穴沉积物构成 ,具有洞穴堆积构造、角砾状构造、栉壳状构造 .氢氧同位素特征表明为大气水 ,硫碳同位素说明成矿物质来自围岩 .上述矿床地质特征较充分说明该矿床是典型岩溶矿床 .岩溶成矿新认识的提出为老岭地区找矿拓宽了思路 。Based on field and indoor study, the author proposed that the Huanggoushan gold deposit be a representative karst one for the first time in 1991. The deposit occurs in the contact zone between dolomite marble of Zhenzhumen formation and schist of Huashan formation, Laoling group, Lower Proterozoic.Orebodies exhibit domal, tubular and funnel shapes. The orebody is composed of karst speleothem, with speleothem structure, brecciform structure and pectinate structure.Meteorological water is proved by H and O isotopic characteristics. S and C isotopes show that metallogenic materials were derived from surrounding rocks. The above mentioned geological features of the deposit suggest that it belong to a representative karst gold deposit. The new cognition proposed in this paper is theoretically and practically significant for ore searching in the Laoling area.
