中文摘要: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。
Abstract:The Jiama copper polymetallic deposit in Tibet has expanded its resources successfully through recent exploration and thus become one of the most significant large-size porphyry copper deposits in Gangdese. Based on an analysis of the definition of worldclass copper deposit and a comparison with worldclass copper deposits in North America, South America, southwest Circum-Pacific region and other areas, the authors hold that the Jiama copper polymetallic deposit has the potential of a worldclass copper, gold, silver, molybdenum polymetallic deposit in that it is characterized by three ore types (skarn, porphyry and hornfels) in one deposit which were formed at the uplifting stage of Qinghai-Tibet Plateau in Late Tertiary. In the future exploration, three aspects are worthy of especial attention: research and exploration of metallogenic mechanism of the skarn type copper ore; research and assessment of ore-bearing potential of buried rock bodies; research on metallogenic mechanism of large-scale concentration of copper, gold, silver, molybdenum and other metals. The subconscious of “no large-size hydrothermal ore deposit is existent” must be broken and a new assessment system for mineral resources should be estabished.
