摘　　要：吉林香炉碗子金矿位于华北地台北缘柳河地堑西侧太古宇鞍山群斜长角闪片麻岩、斜长角闪岩、变粒岩中。为一典型的隐爆角砾岩筒型中型金矿床。在空间和成因上受控于爱林东山、爱林西山隐爆角砾岩体。矿体呈脉状产于角砾岩内的蚀变破碎带中。流体包裹体以液相为主 ,盐度 5.7%～ 1 3.5% ,成矿温度 1 73～ 355℃ ,包裹体成分表明为 H2 O-CO2 -Na Cl体系。矿床成因属次火山岩隐爆期后成矿的蚀变岩型金矿。The Xiangluzi gold deposit is a middle sized deposit hosted in breccia pipes. It is located in plagioamphibole gneiss, plagioamphibole and metadolerite of Archean Anshan Group in western Liuhe graben on the north margin of North China platform. The gold deposit is spatially and originally controlled by Ailinxishan and Ailindongshan breccia pipes. The orebodies occur in the altered fracturing zone in the breccia pipes. The liquid phase dominated fluid inclusions are characterized by low salinity of 5.7%~13.5%wt NaCl, homogenization temperature of 73~355℃ and chemical composition system of H 2O CO 2 NaCl. The deposit belongs to alteration type of gold deposit mineralized after the cryptoexplosion of subvolcanic rocks.
