中文摘要:乳山金矿床位于牟平-乳山金矿带中部，产于昆嵛山花岗岩体中部，是胶东近年来探明的重要金矿床之一。在地质和地球化学方法综合研究基础上提出乳山金矿床属于石英脉型金矿床，是由中生代壳源深熔花岗岩岩浆期后中温热液作用形成的；矿石中金以碲金银矿、银金矿、自然金等形式产在黄铁矿及裂隙中，其物质来源于太古界胶东群地层。
Abstract:The Rushan gold deposit, one of the recently-proven large gold deposits in east Shandong, lies in the central part of the Muping-Rushan gold metallogenic belt. Based on research work in such aspects as regional geology, ore deposit geology, wall rock alterations, ore types, ore minerals, ore-forming stages, thermometry and gas-liquid composition of inclusions in quartz, and hydrogen-oxygen isotopic geochemistry, the author has reached the following conclusions: 1. The Rushan gold deposit is a postmagmatic mesothermal pyrite quartz-vein type gold deposit related to Mesozoic Kunyushan granite. 2. The ore-control structure is a compound structure formed by two sets of faults trending respectively N 15°E and N 65°E. 3. From potassic alteration to the formation of siderite quartz veins, the ore-forming process experienced four stages, in which the formation of pyrite quartz veins and phyllic rock seemed to be the major stage whose formation temperature, pressure and oxygen fugacity(logfO2)being 295～311℃, 7.58×104～7.77×104 KPa and -33.3～-35 respectively. 4. The ore-forming substances were derived from Jiaodong Group, and the weak acid ore-forming hydrothermal solutions rich in Fe2+, SO4-2, HCO3- and CO2 evolved from postmagmatic weak alkaline hydrothermal solutions rich in K+, Na+ and Cl. 5. Gold occurs in pyrite and its cracks as micrograined native gold, electrum and petzite, associated with altaite and tellurobismuthite.
