| 摘 要： | 山东大尹格庄金矿埋深距地表距离大于200 m,属典型的隐伏矿床。选择大尹格庄金矿开展金属活动态测量、地球气测量、地电化学测量、土壤全量测量的方法,以检验深穿透地球化学方法勘查隐伏矿的有效性。试验结果显示:在埋深达300 m的隐伏金矿体上方发现了较明显的地球气、水提取与地电化学Au异常,异常与已知金矿体位置吻合程度较高,而土壤全量测量只在蚀变带头部有所反映,显示了深穿透地球化学方法在隐伏矿勘查中的良好应用前景。

| Abstract: | The deep-penetrating geochemical method is a new tool of exploration for hidden deposits. A comparative survey was conducted in the Dayingezhuang Gold Ore Deposit, a typical hidden ore deposit with a buried depth of 200 m, by using selective leaching of mobile forms of metals in overburden (MOMEO), geogas method (GEOGAS), geoelectro-chemical method (CHIM) and total soil survey, so as to prove the effectiveness of the deep-penetrating geochemical methodology. The result shows that considerable anomalies of GEOGAS, aqueous extract and CHIM due to a hidden ore body of 300 m deep were successfully detected, whereas a weak anomaly of total soil survey was only detected at the top of alteration zone, indicating that the deep-penetrating geochemical method has good prospects of exploration for hidden deposits. |
