| [摘 要]经过对西藏班-怒成矿带多龙矿集区的研究，提出了含矿花岗闪长斑岩特征、构造与铜矿化体关系、矿体围岩蚀变特征及找矿意义、矿体风氧化带特征、地层接触带与铜矿化的规律、铜矿化的物探异常特征、铜矿化的化探异常特征等8个成矿—找矿模型标志信息，组成找矿靶区定量预测数学模型的8个统计变量。针对区内地质工作基础较差的现实情况，将加权特征分析方法的应用到多龙矿集区找矿靶区预测中，优选出10个具代表性的见矿钻孔，作为模型单元，对7个未知预测单元进行了定量预测，优选了找矿靶区。 |

| Abstract: Through the long-term studies of the Duolong mining area in the Bangonghu-Nujiang metallogenic belt of Tibet, this study proposed 8 pieces of ore-prospecting indicatory information: ore-bearing granitic porphyries, relationship between structure and copper ores, altered characteristics of wall rock and significance of ore prospecting, oxidation zone of ore body characteristics, regularities of strata contact and copper mineralization, characteristics of geophysical copper mineralization and the characteristics of geochemical copper mineralization, and these 8 pieces of information comprise the 8 statistical parameters of a mathematical model. Considering the poor previous geological work in the study area, we apply a weighted analysis method to prospecting in the Duolong ore district, and select 10 representative drill holes with seen ores. Then we utilize them as model units to do quantitative prediction on 7 unknown units, and thus optimize the prospecting target zones. |
