摘　　要：高家店杂岩体位于冀东幔枝构造核部岩浆-变质杂岩金矿集区内,该矿集区内分布着多个大中型金矿床。通过岩石学和矿物学研究,确定了高家店杂岩体是多期次侵入的复式岩体,主要岩石类型为正长岩、花岗岩和闪长岩。通过元素含量特征分析,确定了Au为研究区成矿有利元素。通过单元素及组合元素异常特征分析,确定了找矿靶区。通过勘探工程对1、10、13号组合异常进行验证,发现了Au-N1、Au2、(17)、(19)四条金矿体和多条金矿化带,表明本区土壤地球化学找矿的有效性,也证明了本区具有较好的找金前景。The Gaojiadian complex is located in the magmatic-metamorphic complex gold deposit area in the mantle branch structural of Eastern Hebei Province,where there are several large and medium-sized gold deposits.Through petrology and mineralogy research,it is determined that the Gaojiadian complex is a multiple-intrusive complex rock mass,and the main rock types are syenite,granite and diorite.Through the analysis of element content characteristics,Au was determined to be the favorable element for mineralization in the research area.Through the analysis of anomaly characteristics of single element and combined element,the prospecting target area was determined.Through exploration engineering,four gold orebodies of Au-N1,Au2,(17),(19)and several gold mineralization zones were discovered by verifying the anomaly of No.1,10 and 13 assemblages,which shows the effectiveness of soil geochemical prospecting in this area,and also proves that this area has a good prospect of gold prospecting.
