| 摘 要： | 本文根据我国六个大型或特大型金矿床(田)的伴生金属矿物特征与围岩蚀变作用,分析了应用激电法间接找金的物性前提。并通过吉林夹皮沟、胶东焦家、云南哀牢山、河南等几个金矿床的找矿实例简述了激电找金的应用效果与不利因素。指出尽管有局限性,在有利的地质—地球物理条件下,激电方法仍不失为一种比较有效的找金物探方法。为提高找金命中率,特别是找寻盲矿、隐伏矿,在查证化探异常与已知矿区外围普查中应积极采用激电方法。

A BRIEF DISCUSSION ON THE APPLICATION OF IP METHOD TO GOLD PROSPECTING |

| Abstract: | Based on characteristics of accompanying metallic minerals and wall lock alterations in six large-sized or gigantic gold deposits (fields), this paper analyses the physical prerequisite for indirect gold prospecting by using IPmethod. With the ore-prospecting work conducted in such gold deposits as Jiapigou of Jilin, Jiaojia of eastern Shandong, and Ailaoshan of Yunnan as examples, the author describes briefly the effectiveness of IPmethod in gold prospecting as well as the unfavorable factors affecting its application. It is pointed out that, though of some limitations, the IPmethod remains a fairly effective geophysical prospecting method in search for gold deposits under favorable geological-geophysical conditions. In order to raise the rate of conect detection in gold prospecting, the IPmethod should be actively used in such aspects as the search for concealed and blind deposits, the inspection of geochemical anomalies and the 1:50000 integrated geophysical-geochemical prospecting in metallogenic provinces. |
