摘　　要：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。Duobuza Copper Deposit in Tibet, the first large-scale porphyry copper deposit discovered along Pangong Lake-Nujiang River metallogenic belt in recent years, is situated in Duobuza tectonic magmatic arc in the northern margin of Pangong Lake-Nujiang River suture zone. It was formed during the evolution period of archipelagic arc-basin system of Pangong Lake-Nujiang River of Early Cretaceous with metallogenic age of 120 Ma. The deposit is related to quartz diorite porphyrite and granodiorite-porphyry intrusions in the strata of Meiriqiecuo Formation of Early Cretaceous. Boasting of present measured resources of Cu and Au of 2.30 million tonnes and 92 tonnes with average grade of 0.51% and 0.2 g/t respectively, Duobuza Copper Deposit ranks as one of the super large-scale deposits and one of the national strategic reserve bases of mineral resources. The dataset of resource reserves in Duobuza Porphyry Copper Deposit of Tibet is built based on the valuable data obtained in the mineral survey during 2005-2010. It contains 10 data tables, in which the grades and relevant calculated results of single-engineering industrial ore bodies and low-grade ore bodies in Duobuza Copper Deposit are mainly included. Furthermore, all detailed data related to reserve calculation are summarized and collated systematically in the dataset.
