中文摘要:
      云南省龙陵县杨梅田铜矿为中温热液型铜矿床,铜矿体的分布宏观上受上奥陶统第2层底部层位的控制,主要产于构造破碎带中。在系统研究赋矿地层和矿床的元素组合、成矿成晕的轴向分带及叠加特征基础上,总结了深部盲矿预测的构造叠加晕标志;根据矿床成矿规律和探矿构造圈定有利成矿空间,结合构造叠加晕原理,在有利成矿空间上方坑道或钻孔中的前缘晕叠加部位圈定盲矿体预测靶区,并对定位预测的靶区进行工程验证。验证结果证明了构造叠加晕找盲矿法在热液型铜矿深部盲矿体定位预测的有效性。
英文摘要:
      Yang Meitian copper deposit in the Longling county of Yunnan province is a medium-temperature hydrothermal deposit. Macroscopically the Cu ore bodies are controlled by strata at bottom of the second layer of Upper Ordovician Series occurring mainly in the structurally fractural zone. This paper systematically studies the elements combination of ore-bearing strata and the ore deposits, the ore-forming and halo-forming axial zoning and their superposition and summarizes the structural superimposed halo signs for the prediction of deep blind ore. Targets are delineated on basis of metallogenic law and principle of the structural superposition theory workings designed and ore encountered and the structural superimposed halo prospecting method is first proved effective in the hydrothermal Cu ore prospecting.
