| 摘 要： | 通过对小秦岭金矿成矿地质条件及成矿物质来源的讨论 ,认为区域变质、混合 (花岗 )岩化等促使基底岩系中金被多次活化析出 ,在变质核杂岩持续隆升背景下 ,成矿流体向控矿剪切带运移沉淀 ,燕山期构造—岩浆活动为金矿富集定位创造了热—构造环境。提出金矿分布与变质核杂岩构造具有对应性 ,本区金矿化具垂向构造分带性。

| Abstract: | Discussion on the metallogenetic geology and ore forming source of gold deposits in Xiaoqinling has revealed that regional metamorphism and migmatization (granite) separated gold out from basement rocks by mobilization many times. With uplift of metamorphosed complexes, metallogenetic fluid migrated and deposited in ore control shear zones. The Yanshanian structural migmatic lava movement created thermal structural settings for gold enrichment. This paper has revealed the correspondence of the gold distributions to the structures of metamorphosed complex and the vertically zoning features of gold mineralization. |
