西藏甲玛铜多金属矿床随着勘探工作的深入取得重大成果,已成为冈底斯斑岩铜矿带内最重要的大型矿床之一。通过对世界级铜矿含义的解析,与北美、南美、环太平洋西南部及其他主要产区的世界级铜矿进行对比,认为甲玛铜多金属矿床以矽卡岩型、斑岩型和角岩型三位一体、形成于晚第三纪青藏高原隆升阶段为显著特点,具有成为世界级铜、金、银、钼多金属矿床的潜力。在下一步的勘查过程中,需要进一步加强对矽卡岩型铜矿石成矿机制的研究和勘探,加强隐伏岩体含矿性的研究与评价,加强铜、金、银、钼多种金属物质大规模聚集的成矿机制的研究,并需要打破“热液矿床大不了”的潜意识,建立起新的资源评价体系。
With the great achievements of exploration work, the Jiama copper polymetallic deposit in Tibet has become one of the most important large deposits in the Gangdese porphyry copper belt. Through the analysis of the meaning of world-class copper mine and comparison with world-class copper mines in North America, South America, southwestern Pacific Ocean and other major producing areas, it is concluded that the Jiama copper polymetallic deposit is characterized by skarn type, porphyry type and angle The trinity was formed in the late stage of the Qinghai-Tibet Plateau uplift. It has the potential to become a world-class copper, gold, silver and molybdenum polymetallic deposit. In the next exploration process, we need to further strengthen the study and exploration of the skarn-type copper ore mineralization mechanism, strengthen the study and evaluation of the concealed rock mass mineralization, strengthen the large variety of metallic substances of copper, gold, silver and molybdenum Scale accumulation of mineralization mechanism of research, and the need to break the “hydrothermal deposit ” subconscious, to establish a new resource evaluation system.
