-
摘要: 本文将猫岭金矿床划分为沉积变质、变质热液和交代重熔岩浆热液三个成矿期。由硫、氢、氧同位素,稀土元素特征及包裹体成分研究结果表明变质热液期为主成矿期,主要成矿物质来自围岩,矿床属变质热液成因。Abstract: The Maoling gold deposit in Gaixiancountry, Liaoning province, occurs in the second member of Gaixian Fm. of Liaohe Gr., Which consists of phyllite,chorite-sericite phyllite and sericite-quartz phyllite with sericite quart-zite. In the miner area there are two granite masses(i.e. Maoling granite an woeongquan granite), which are of proterozoic metasomatic-anatect type.
