钦杭结合带是扬子板块与华夏古板块经晋宁—加里东多期板块俯冲、碰撞拼贴的产物(胡肇荣,2009)。其中汇聚了20个特大型矿床和百余处大中型矿床,现已被正式列入国家资源保障工程规划的重点研究区域(顾明光,2011),命名为“钦杭成矿带”。该带于中晚侏罗世复活,沿其发育一系列铁、铜多金属和钨锡多金属矿产,成矿主要与燕山期中酸性-酸性岩浆作用有关,是华
The Qin-Hang combination zone is a product of subduction and collision collage between the Yangtze plate and the Huaxia old plate via the Jinning-Caledonian plate (Hu Zhaorong, 2009). Among them, there are 20 super-large-scale deposits and over a hundred large and medium-sized deposits. Now it has been formally included in the key research area of National Resource Security Project Planning (Gu Mingguang, 2011) and named as “Qinhang Metallogenic Belt”. The belt revived in the middle-late Jurassic and developed a series of iron, copper polymetallic and tungsten-tin polymetallic deposits along its course. The metallogenesis was mainly related to the acid-acid magmatic activity in the Yanshan Period,
