引言自1912年到1982年底以来,麦克因蒂尔矿山采出的3269685吨矿石中提炼出329700公斤金,而珍珠湖斑岩容矿的脉型和浸染型Cu—Au—Ag—Mo矿化到1959年以前未被发现。后一种矿化由构成被金—黄铁矿—石英—Au脉系分隔的明显矿体组成。珍珠湖斑岩容矿的Cu—Au—Ag—Mo矿床的某些特征,如在伴生的侵入岩成分上、在绢云母化核心、在赤铁矿—硬石膏蚀变、金属组合和品位等方面,明显地与显生宙斑岩铜
Introduction Since 1912 to the end of 1982, a total of 327,700 kg of gold has been extracted from 3,269,685 tonnes of ore mined at the Magnatir Mine, while the vein type and disseminated Cu-Au-Ag-Mo mineralized in the Pearl Lake porphyry have been mineralized to Not discovered before 1959. The latter mineralization consists of overtly formed ore bodies that are separated by gold-pyrite-quartz-Au veins. Some of the characteristics of the Cu-Au-Ag-Mo ore bed hosted by the Pearl Lake porphyry include the associated intrusive rocks, the sericitization core, the hematite-anhydrite alteration, the metal assemblage and the grade In the aspect, it is obviously associated with the Phanerozoic porphyry copper
