辽宁红透山式铜锌矿床地球化学异常特征及找矿评价指标

本文根据红透山矿区的岩石、矿石的微量元素和某些常量元素的特征,以及矿床中硫同位素的分布,对矿床的原生异常和次生异常的特征进行了研究,并提出了普查和详查的化探方法。认为1:5万比例尺的水系沉积物测量方法可有效圈定有希望的远景区,进一步的详查可用1:1万或1:5千比例尺的土壤测量(配合自然电场法)能直接圈定矿体或矿化带。对于找盲矿体可投入原生晕方法,并与地电化学、壤中汞气测量等方法配合可获得明显效果。

GEOCHEMICAL ANOMALIES OF THE HONGTOUSHANTYPE COPPER-ZINC DEPOSIT IN LIAONING PROVINCEAND THE CRITERIA FOR ORE PROSPECTINGAND EVALUATION

Based on characteristics of minor elements and some major elements inrocks. and ores of the Hongtoushan ore district as well as sulfur isotope distri-bution in the ore deposit, this paper studies the features of primary and sec -ndary anomalies in the ore deposit and puts forward methods for geochemicalreconnaissance and detailed investigation. It is held that the 1:50,000 streamsediment survey can delineate effectively promising prospect areas, and thatthe further detailed investigation can directly delineate orebodies or minerali-zed zones by means of 1:20, 000 or 1:5, 000 soil survey in cooperation with theself-potential method. In prospecting for blind orebodies, the primary halomethod can be used in combination with such techniques as geoelectric che-mistry and soil mercury survey, which might produce obvious effects.
