城门山铜矿地质特征及深部三维成矿预测

结合城门山铜矿地质勘查成果，对矿区成矿地质背景进行了详细分析，并分别从矿体特征、矿体地球化学特征2个方面对矿床地质特征进行了详细探讨。在此基础上，为进一步探究矿区深部矿体分布规律，结合MapGIS-TDE三维可视化系统，提取了矿区328个钻孔的数据资料，建立了城门山矿区三维地质成矿模型。基于该模型，对区内资源潜力和深部成矿条件进行了预测，结果表明：矿区深部及边缘有较大的找矿潜力，矿体整体呈柱状展布，受岩体就位空间控制，略向NW倾，向深部仍有较大延深，最大见矿厚度达269.10 m（仍未揭穿），预测结果与实地勘查资料基本一致，对于区内进一步开展深部找矿工作有一定的参考价值。

Geological Characteristics and Deep Three-dimensional Metallogenic Prediction of Chengmengshan Copper Mine

Combing with the geological prospecting achievements of Chengmengshan copper mine,the ore-forming geolog-ical background of Chengmengshan copper mine is analyzed in detail,the ore deposit characteristics is discussed in depth from the two aspects of the geological characteristics and geochemical characteristics of the ore-bodies. Based on the above analysis results,in order to analyze the distribution regularity of the deep ore-bodies,based on the MapGIS-TDE three-dimensional visu-alization system,the data of 328 drillings is obtained and the three-dimensional geological metallogenic model of Chengmengs-han mining area are established. Based on the three-dimensional geological metallogenic model, the resources potential and deep metallogenic conditions are predicted effectively. The results show that the prospecting potential of the deep and margin of Chengmengshan mining area is huge,the ore-bodies are distributed with column shape on the whole and they are controlled by the rock mass occurrence space,slightly NW tendency,the ore-bodies extension in the deep is still large,the maximum thick-ness of the ore-bodies is 269. 10 m(the ore-bodies are still exposed thoroughly),the above prospecting prediction results is consistent to the geological prospecting achievements basically,therefore,the research results in this paper has some reference for the further deep prospecting work in Chengmengshan mining area.
