西秦岭地区脉岩与金矿化的关系

脉岩与金矿化在时空上密切伴生是一个非常普遍的现象。西秦岭地区几乎所有金矿床矿区中都有大量各种类型的脉岩。文章从金矿密集区伴生脉岩主要特征、金矿床与花岗岩和脉岩的空间关系、金矿成矿与脉岩成岩时间相近、金矿成矿物质与脉岩和花岗岩同源等4个方面分析研究了脉岩与金矿化的密切关系。认为脉岩与金矿化是同一构造—岩浆活动旋回内区域地壳演化、壳—幔相互作用的系列产物,由此造成两者不仅在时空上密切伴生,而且物质成分上具有相同来源和继承演化的成因联系,岩浆侵入体和脉岩与成矿物质同源,时空密切相伴。

RELATION OF DIKE ROCK AND GOLD MINERALIZATION IN WEST QINLING REGION

It was an extraordinary universal phenomena that the dike rock and gold mineralization exist together spatially and have the nearly same age.The paper analyzed the close relations from 4 aspects as the features of dike rocks accompanied with gold mines in gold concentrated area,the spatial relation of granites and dike rocks,the close age of gold metallogensis and rock-forming,the same source for metallogenetic material of gold and granites.The author holds that both of dike rock and gold mineralization be ...
