西藏多不杂斑岩铜矿资源储量数据集

西藏多不杂铜矿是班公湖−怒江成矿带近年来发现的第一个大型斑岩铜矿床。该矿床位于班公湖−怒江缝合带北缘多不杂构造岩浆弧中，形成于早白垩世班公湖−怒江多岛弧−盆系演化时期，成矿年龄为120 Ma，成矿与侵位于早白垩统美日切错组地层中的石英闪长玢岩、花岗闪长斑岩有关。目前已探明铜、金资源量分别为230万吨，92吨，平均品位分别为0.51%、0.2 g/t，已达超大型矿床规模，是国家矿产资源战略储备基地。本数据集是在2005—2010年对该矿区矿产勘查所取得的宝贵数据基础上，开展的数据库建设的成果，采用10个数据表，重点汇集了多不杂铜矿单工程工业矿体和低品位矿体的品位数据及其计算结果，并对与储量计算有关的所有细节性数据做了系统性的归并整理。

The Duobuzha Copper Deposit in Tibet is the first large-scale porphyry copper deposit discovered in recent years within the Bangong Co-Nujiang Metallogenic Belt. This deposit is located in the Duobuzha tectonic-magmatic arc on the northern margin of the Bangong Co-Nujiang Suture Zone, and formed during the evolutionary period of the Bangong Co-Nujiang multi-island arc-basin system in the Early Cretaceous, with a metallogenic age of 120 Ma. Mineralization is associated with quartz diorite porphyry and granodiorite porphyry intruded into the strata of the Early Cretaceous Meiriqiecuo Formation. Currently, the proven copper and gold resource reserves are 2.3 million tonnes and 92 tonnes respectively, with average grades of 0.51% and 0.2 g/t respectively. It has reached the scale of a super-large deposit and serves as a national strategic mineral resource reserve base. This dataset is the outcome of database construction based on valuable data acquired from mineral exploration in this mining area between 2005 and 2010. It utilizes 10 data tables, focusing on compiling grade data and their calculation results for industrial ore bodies and low-grade ore bodies from single drill holes of the Duobuzha Copper Deposit, and systematically consolidates all detailed data related to reserve calculation.
