中文摘要:
      为扩大夏家店金矿规模，对夏家店金矿外围刘家峡测区进行了1:10000土壤地球化学测量。利用数理统计方法，对Au及其伴生元素Ag、Cu、Pb、Zn、As、Sb、Hg、Mo及Bi等10种元素进行了相关性分析及R型因子分析，划分出F1[Au、Ag、As、Hg、Sb]、F2[Ag、Cu、Pb]、F3[Zn]、F4[Mo]及F5[Bi]共5个因子分组；并将其单元素异常及组合元素异常处理成图，分析了Au及其伴生元素的空间分布规律。结合数理统计分析结果、元素异常图及研究区地质情况，对夏家店金矿进行成矿预测，圈定出6个预测区。通过探槽及钻探工程验证，最终于3个预测区内发现了4条金矿体，成功实现金矿边部找矿突破，验证了土壤地球化学测量方法在研究区的适用性，同时发现新的赋矿层位泥盆系西河岔组，为夏家店金矿下一步找矿工作提供了有效的找矿方法及新的方向。
英文摘要:
      In order to expand the scale of the Xiajiadian gold deposit, a 1:10,000 soil geochemical survey was carried out on the Liujiaxia survey area outside the Xiajiadian gold deposit.The author uses the correlation analysis and R-factor analysis to analyze Au and its associated elements Ag, Cu, Pb, Zn, As, Sb, Hg, Mo and Bi,as well as divide F1 [Au, Ag, As, Hg, Sb], F2 [Ag, Cu, Pb], F3 [Zn], F4 [Mo] and F5 [Bi] a total of 5 factor groups;The single element anomaly map and the combined element anomaly map were made，to analyze the spatial distribution of Au and its associated elements.Combining mathematical statistics analysis results,elemental anomaly maps and geological conditions of the study area, the metallogenic prediction of the Xiajiadian gold deposit is carried out and 6 metallogenic prediction area were delineated.Through the exploration of trench and drilling engineering,four gold ore bodies were discovered in three prediction areas,and the prospecting of gold ore exploration outside the Xiajiadian deposit was successfully realized. The applicability of soil geochemical measurement methods in the study area was verified, and new The ore-bearing layer of the Devonian Xihecha Formation provides an effective prospecting method and a new direction for the next prospecting work of the Xiajiadian Gold Mine.
