| 摘 要： | 西藏班公湖-怒江板块结合带地质构造复杂,成矿条件优越,具备形成金矿的地质背景条件,是西藏最具潜力和规模巨大的贵金属成矿带.但由于该区地质工作程度较低和对成矿规律认识不清,至今没有一个可供开发的岩金矿产地.通过班公湖-怒江板块结合带砂金、岩金矿(化)点,地球化学异常和重砂异常的分布并进行控矿因子分析,建立了该带两种岩金遥感找矿模式,通过验证发现该区具有大型远景规模的岩金矿产地,并认为蚀变岩型金矿和穆龙套型金矿是该带最重要的两种矿床类型,具有巨大的找矿潜力.

| Abstract: | The Bangong Co-Nujiang River Plate Juncture in Tibet has complicated geological structure and favorable metallogenic conditions, and serves as a large potential ore-forming belt of precious metal resources. However, due to very insufficient geological exploration work and low level of metallogenic regularity study, no valuable primary gold deposits have yet been found. Based on a study of placer and primary gold ore spots, geochemical anomalies and placer mineral anomalies in the belt, in combination with an analysis of the ore-control factors, the authors advanced two remote sensing prospecting models for primary gold ore deposits, whose verification led to the discovery of a gold area with great reserves. The alteration rock type and the Mulongtao type recognized by the authors are two most important types of primary gold ore deposits in the belt, which show great potentials in the prospecting for gold deposits. |
