| 摘 要： | 查拉普岩金矿床是藏南著名的北喜马拉雅构造带中新发现的第一个也是最大一个岩金矿床, 是西藏境内迄今为止报道的首个卡林型金矿床.但它的发现只是藏南岩金找矿突破的前奏, 随着勘查研究工作的深入, 北喜马拉雅构造带在岩金或以岩金为主的金锑找矿方面将会取得重大突破.首次系统介绍查拉普岩金矿床成矿环境、成矿特征的同时, 对其成矿时代提出约束, 得出该类型金矿最终成矿作用与藏南大规模拆离系的形成和演化密切相关, 也显示北喜马拉雅与冈底斯斑岩铜矿带在晚新生代成矿方面具有某种成因联系, 为该区进一步的岩金找矿提供了参考和借鉴, 具有重要的理论及现实意义.

| Abstract: | Chalapu gold deposit, situated in the northern Himalayas, is the largest hardrock gold deposit which happens to be the very first one found in southern Tibet. It is also the first Carlin-type gold deposit reported so far. Its discovery is the beginning of finding hardrock gold deposit in southern Tibet, and there will be many breakthroughs in hardrock gold and antimony deposits prospecting in the northern Himalayas with further work. This paper introduces the metallogenic background and mineralization characteristics, ages restriction of the gold deposit. We conclude the mineralization of the gold deposit is related to the southern Tibet detachment forming and evolvement, and the ore-forming is related between the northern Himalayas and the Gangdise porphyry copper belt in Late Cenozoic. This discovery is of great significance both in theory and practice for finding hardrock gold deposits in the region. |
