摘要
马头滩金矿床赋存于晚古生代中酸性火山岩中，受脆韧性剪切带控制，成矿年龄与控矿的糜棱岩带的形成时代相近，成矿物质主要来自围岩火山岩，成矿流体由变质水和大气降水溶液组成。这些特征说明该矿床与剪切带之间存在时－空和成因联系，是一个典型的韧性剪切带型金矿床。
The Matoutan gold deposit occurs in mid acid volcanic rocks The gold bodies was controlled by brittle ductile shear zone Ore forming age is the same as the forming of mylonite zone controlled ore bodies Ore forming matter comes from wall rocks volcanic rocks Ore forming fluid was composed of metamorphic water and meteoric water These characteristics show there are time space and genesis relationships between the gold bodies and shear zone Matoutan gold deposit is a ductile shear zone type gold deposit as well
