| 摘 要： | 高松山金矿是在黑龙江省北部地区新发现的一个低硫型浅成低温热液矿床,位于天山—蒙古—兴安造山带和环太平洋构造带的重叠部位。区域地质背景、矿床地质特征和岩石地球化学数据综合分析认为高松山金矿产于岛弧或陆缘环境的中基性火山岩中,其成矿模式为中--晚白垩世太平洋--欧亚板块的相互作用由挤压转变为伸展的过程中,陆内碰撞晚期或碰撞后阶段形成的岩浆热液与中基性的钙碱性火山岩发生反复的水岩反应,最终在火山机构断裂和区域断裂的交汇部位沉淀并富集成矿。

| Abstract: | The Gaosongshan gold deposit is a newly discovered low sulfur type epithermal deposit in northeastern Heilongjiang,located in the overlapping part of the Tianshan-Mongolia-Xing＇an orogenic belt and the circum-Pacific tectonic belt.Combined with the comprehensive analysis of regional geological background,geological characteristics of deposits and petrological geochemical data,the authors considered the Gaosongshan gold deposit produced in the middle and basic volcanic rocks of island-arc or active continental margin environment.The metallogenic model is the water-rock reaction between middle and basic calc-alkaline volcanic rocks and magmatic hydrothermal formed in late continental collision or after collision,during the process of extrusion translates into extension between the Pacific and Eurasian plates in Middle and Late Cretaceous,and finally enriched and formed deposits at the intersect parts of volcanic mechanism and regional faults. |
