钦杭成矿带是由扬子、华夏两大古陆块于晋宁期发生碰撞拼贴形成的巨型板块结合部,西起广西钦州湾、经粤西、湘东北、赣中延伸到杭州湾。在区域地质上,钦杭成矿带西南段的岩石类型主要为中酸性岩浆岩和碳酸盐岩,为夕卡岩型矿床的形成提供了重要的背景,这也得到了诸多实例的证实。综合前人多年研究,本文试图概述部分夕卡岩型矿床找矿标志,并将之与钦杭成矿
The Qinhang metallogenic belt is a giant plate junction formed by collision and collage of two ancient terraces of Yangtze and Huaxia in the Jinning Period. It extends from Qinzhou Bay in Guangxi to the west of Guangxi in Guangxi and extends to the west of Hangzhou in western Guangdong, eastern Hunan and Jiangxi. In regional geology, the rock types in the southwestern part of Qinhang metallogenic belt are mainly acidic magmatic rocks and carbonate rocks, which provide an important background for the formation of skarn deposits. This has been confirmed by many examples. Based on the research of predecessors for many years, this paper attempts to outline some prospecting signs of skarn deposits and compare them with Qinhang formation
