| 摘 要： | 在湖南坪宝铅锌多金属矿田外围柳塘预测找矿靶区,采用高精度磁测、高精度重力、高灵敏度土壤、岩石测量、碳氧同位素测定等综合方法普查、详查,以“磁场跃变区”及Pb、Zn、Ag、Sb、As等弱异常为主要标志,在地表无任何矿化蚀变显示的柳塘预测区,发现400m以下的全隐伏铅锌银矿床,这阐明了新方法新技术是成矿远景区(带)矿产资源调查评价中提取深部找矿信息标志的最佳方法,总结了找矿预测的基本思路。通过该矿床的发现,说明“预测—普查一致性”原则是成功的。

| Abstract: | In the Liutang ore-prospecting target area on the outskirts of the Hunan lead-zinc polymetallic orefield which has been investigated in great detail,the authors used integrated methods,such as high-precision magnetic survey,high-precision gravity survey,high-sensitivity soil and rock survey,and carbon-oxygen isotope determination, to conduct reconnaissance and detailed investigation.In the Liutang prognostic area which shows no mineralization and alteration at surface,the utilization of the"magnetic field sudden change area"and weak Pb,Zn,Ag,Sb and As anomalies as the main indicators led to the discovery of a concealed lead-zinc-silver deposit at the depth of greater than 400 m.It seems that the utilization of new methods and new techniques is the best means for extracting deep ore-prospecting information in the investigation and evaluation of mineral resources in ore prospect areas (belts).This paper has summed up the basic train of thought for ore prospecting and prediction,and illustrated the successfulness of using the "prediction-reconnaissance consistency" principle. |
