摘要
四道沟金矿是地质条件较为复杂的矿床，对其成因问题前人观点众说不一。比较典型的主要有岩浆热液成因和沉积变质成因，成因不同直接影响着找矿方向。根据矿床地质特征和工作实践认为：该矿床成因应为沉积变质－ 岩浆热液叠加改造型矿床。所以沉积变质和岩浆热液成矿的有利条件均应成为找矿的主要方向。据此开展的找矿工作已初步获得突破性进展。
Sidaogou gold deposit is complex in geological conditions.There are many different opinions on its genesis,in which magamatic hydrothermal genesis and sedimentary metamorphic genesis are the major typical ones.The genesis of a deposit directly influence the direction of ore prospecting. On the geological characteristics and ore prospecting practice of the author,the paper puts forward that the gold deposit is of sedimentary metamorphic magmatic hydrothermal superimposed reformed type. So, all the conditions which are favourable to sedimentary metamorphic and magmatic hy drothermal metallogenesis should be taken as the major directions of ore prospecting.
