摘要
应用美国"三部式"资源评价方法原理,对中国大陆斑岩铜矿成矿地质背景、时空分布规律、矿床模型等方面研究,圈出46个远景区;以中国1999年金属储量数据库和区划矿产地数据为基础,建立了铜矿数据库共984个,分不同类型进行品位吨位的研究,以此为基础构造出数字找矿模型和开发出矿产资源定量评价模型程序,并计算了每个远景区的概率资源量,为评估中国斑岩铜矿资源潜力提供了参照。
Using the method and principle of the "three-part" mode of mineral resource assessment,we have studied the geological setting,and temporal-spatial distribution rule and models of the porphyry copper deposits in China.In our assessment we have also included 46 prospective areas.Based on the metal reserves database in 1999 and data from currently producing deposits,we have constructed a database of 984 deposits.We have studied grade-tonnage models according to the different types of mineralization,constructed...
