| 摘 要： | 马庄山金矿位于新(疆)甘(肃)边境。地质、地球化学研究表明,马庄山金矿床受马庄山古火山机构控制,与矿区内同期火山-次火山作用有直接的成因联系,成因类型为浅成中-低温热液型。次火山岩及含金石英脉年代学研究表明,马庄山火山机构形成时代与金矿成矿时代均为中-晚石炭世:次流纹斑岩和次英安斑岩全岩及含金石英细(网)脉石英流体包裹体Rb-Sr等时线年龄分别为301±21Ma、303Ma±26Ma和298Ma±28Ma(95%置信度)。

| Abstract: | Located geographically in the border of Xinjiang Uygur Autonomous Region and Gansu Province and geologically in the juncture of the Siberian, T arim, Kazakhstan and Sino Korean palaeoplate, the Mazhuangshan paleovolcanic apparatus is a typical ore-control one in eastern Xinjiang. Geological and geoche mical evidence indicates that the Manzhuangshan gold deposit, a volcanogenic one, shows direct genetic relationship with contemporary volcanic-subvolcanic activities and is controlled by the Manzhuangshan paleovolcanic apparatus. chronological study on subvolcanic rocks and gold bearing gold veins show that both the paleovolcanic apparatus and the gold deposit were formed during the Middle Carbo niferous with the Rb-Sr isochron ages of rhyolite porphyry, dacite porphyry and fluid inclusions of quartz from the gold-bearing quartz veins to be 301?21Ma, 303?26 Ma and 298?28 Ma (95% confidence), respectively. |
