【摘要】 湖南石门界牌峪地区雄黄矿床中伴有各类矿化角砾岩。从其岩石学、岩石化学、地球化学的特征来看，它是一种由热泉气体及部分物质在封闭还原条件下产生急剧爆发形成的特殊的角砾岩群。主要成因类型有“侵入状”角砾岩、爆破角砾岩、岩溶角砾岩和崩塌角砾岩。常见多种角砾岩叠加，它们是一种极好的控矿容矿载体，具有重要的找矿意义。更多还原

【Abstract】 There are various associated mineralizing breccias at the realgar deposit in Jiepaiyu, Shimeng county, Hunan. After analyzing the characteristics of petrology, petrochemistry and geochemistry, the author suggests that the special breccia rocks be formed by the hot spring gases with part of matters intensively exploding in the conditions of trapping and reduction. The major genesis types include ’intruse’ breccia, exploding breccia, karst breccia and slump breccia. And the breccias frequently overlapped, and the breccias are the excellent ore-bearing load bodies. It is very important for prospecting ore deposits.更多还原
