| 摘 要： | 以火山-次火山岩发育为特征的柳树河子金铜矿(化)区,受晚侏罗-早白垩世火山机构控制.土壤地球化学测量结果表明,Au元素异常与主火山口周围呈环形分布的寄生火山口中次火山岩株(闪长玢岩)分布位置相吻合,Cu元素异常与火山机构中心相酸性次火山岩(花岗斑岩)小岩株空间位置相吻合.结合矿区地质背景分析并进一步对土壤测量数据处理,确定出本区金矿主要控矿构造主要为北西向,北东向和南北向次之,受火山构造和闪长玢岩小岩株联合控制;铜矿主要受花岗斑岩岩株控制. |

| Abstract: | With volcanic-subvolcanic rock as characteristic,Liushuhezi gold-copper deposit field is controlled by Jura-early Cretaceous volcano organization.The result of the pedogeochemical survey indicates that Au abnormality distribution fits with the ringwise distributed subvolcanic laccolith(diorite-porphyrite) around the main crater,and Cu abnormality distribution fits with the acid granite-porphyrite laccolith in the main crater.Combining with the geology background and data processing,it is concluded that the primary direction of Au ore-controlling structure is NW,and then NS and NE,controlled by volcano structure and diorite-porphyrite laccolith,and Cu ore body is controlled by granite-porphyrite laccolith. |
| Keywords: | volcanic terrain pedogeochemical survey measured data ore finding Liushuhezi gold-copper deposit field |
