中文摘要:二号窿是石门雄黄矿区曾开采过的老窿。矿体主要在165 m、140 m、125 m三个标高段富集，从上至下呈现浸染状矿石-角砾状矿石的变化规律，矿石主要化学成分为As、S、SiO2、CaO、Al2O3、Fe2O3等；矿体元素的垂直分带明显，Ba、Hg在矿体上部富集，而Sb在矿体下部含量高。窿内岩溶角砾岩、晶洞与成矿关系密切。地层、古岩溶、构造对成矿具有控制作用。地质、地球化学、地球物理特征表明二号窿深部南西方向可能存在较大的富矿体。
Abstract:The Shimen deposit is a large-size and high-grade realgar deposit in Hunan Province. Characterized by a pipelike orebody and a typical three-layer structural model, the deposit consists of silicalites, karst breccias and brecciated ores in downward succession. The realgar orebody occurs at the contact zone between Lower Ordovician Nianjingguan Formation and Fengxiang Formation. The main country rocks arc composed of oolitie dolomitite, limestone, marl and claystone, and realgar is mainly concentrated at 165 m, 140 m and l25 m, controlled by stratigraphic, lithological characteristics, karst and structure. Systematically described in this paper are characteristics of the realgar deposit, including its natural mode of occurrence as well as geological, geophysical and geochemical anomalies. The ore-control role or the intersection between NE- and EW-trending faults is discussed in detail and, on such a basis, home ore-prospecting targets are indicated.
