| 中文摘要: |
| 宁镇中段铜多金属矿床主要为接触交代型矿床。文章以地质环境和成矿规律研究为基础,采用逻辑信息法综合提取地质、遥感、地球物理和地球化学多层次成矿预测信息,构建逻辑信息法成矿预测要素组合。并以此为指导,按照地质成矿条件有利程度、物化探异常强度与规模、环形构造发育程度、遥感解译蚀变显现强度与规模,进行综合判别确定成矿有利位置,圈定区内夕卡岩型矿床重点找矿靶区。 |
| 英文摘要: |
| In the middle segment of Nanjing-Zhenjiang Mesozoic magmatic belt,the copper polymetallic deposits are dominated by contact metasomatic type.Based on the geological environment and metallogenic regularity the logical-information method is used to extract multi-metallogenic prediction(geological,remote-sensing,geophysical and geochemical) information of skarn-type cooper polymetallic ores.With this method and comprehensively analyzing the favorable degree of geological metallogenetic conditions,intensity and scale of geophysical-geochemical anomalies,development degree of circular structure,intensity and scale of RS-interpretation alteration,the favorable positions of mineralization are determined,and the key prospecting target area of skarn-type copper deposits in the study area are also delineated.Finally,the potential of the key prospecting target area is discussed in detail. |
