在风成土或厚岩层覆盖区,采用常规化探方法难以开展找矿工作。为解决此类地区寻找掩埋矿体或深部盲矿体问题,我们利用自制的仪器,于77年6～8月,与黑龙江冶勘706队协作,在八八一铜(钼)矿区进行了壤中气汞量测量试验。在已知掩埋铜矿上方的风积物覆盖层中,获得清晰的汞气异常;并在未知地段圈定矿化富集地段9处,经钻探验证,其中5处异常已见矿或矿化体。随
In the area of aeolian or thick rock cover, it is difficult to carry out prospecting work by conventional geochemical exploration methods. In order to solve the problem of finding buried or deep blind orebodies in such areas, we made use of self-made instruments and, from June to August in 1977, we collaborate with Heilongjiang Metallurgical Group 706 to carry out soil Gas mercury measurement test. Clearly known mercury gas anomalies were obtained in the aeolian overburden over the known burial copper deposit; 9 locations of mineralized enrichment were delineated in the unknown area, verified by drilling, of which 5 were anomalous mineral or mineralized .
