摘　　要：高松山金矿是与火山作用关系密切的大型浅成低温热液型金矿。矿石类型有含金石英脉、构造角砾岩和蚀变岩型3种。金矿体以零磁场、高电阻为特征,与赋矿围岩存在着明显的物性差异;矿石中Au、Ag、As、Sb、Cu有密切的相关关系;火山岩中金的丰度较高,绝对及相对离散程度较大,异常规模大,强度高,浓度分带明显,具备物化探找矿前提。矿石硫同位素组成具有深源硫特点,H、O同位素特征反映在成矿过程中有大气降水加入。矿床产于中生代下白垩统火山岩中,赋矿岩石的岩石化学特征反映了活动大陆边缘环境。根据地质、物探、化探和遥感等综合信息,确定矿区西部、1号矿体深部及乌云盆地东缘有进一步找矿远景。The Gaosongshan gold deposit is an epithermal deposit related to volcanic action.There are 3 types in the ore type including auriferous quartz vein,structural breccia and altering-rocks.The gold bodies,with no magnetic field and high resistivity,are distinguished with the wall rocks by physical feature.In the gold ore,such elements are closely correlative as Au,Ag,As,Sb and Cu.The abundance of Au in the volcanic rocks is high.Both absolute and relative departure degrees are large.The Au abnormalities are of large-scale,high-intensity and obvious zoning,which can provide important base for the geophysical and geochemical explorations.The S isotope in the ore is characterized by the deep-derived magma sulfur.Both H and O isotopes show that there happened the mixing of the meteoric water during the ore-forming process.The ore body is located in the Upper Cretaceous volcanic rocks whose petrologic geochemistry indicates they formed under the tectonic settings of the active continental margin.According to the data on geology,geophysics,geochemistry and remote sensing,in the west of deposit area,both the depth of ore body No.1 and the east of the Wuyun Basin of Heilongjiang are estimated as metallogenic predication areas.
