前言本区分布有广泛的花岗岩类及铁、铜、稀有金属矿床和矿化,是我国重要的铁、铜矿产区域之一,大冶式铁矿就产于此。多年来,不同的作者将本区铁铜矿床归之为接触交代成矿和热液成矿、火山同生沉积成矿、矿浆成矿、层控成矿、板块成矿。作者根据近些年来各单位在这一地区所获得的岩石学、地球化学及同位素地质学资料的综合研究,认为这些花岗岩类及与其有关的金属矿床和矿化可能是在燕山旋回时,扬子准地台板块与大别板块(古板块)相撞,大别
Preface This area is divided into a wide range of granite and iron, copper, rare metal deposits and mineralization, is one of China’s major iron and copper mineral area, Daye iron ore is produced here. Over the years, different authors have classified the iron-copper deposits in this area as contact metasomatism and hydrothermal mineralization, volcanogenic sedimentary mineralization, ore-forming, stratiform-controlled mineralization and plate mineralization. Based on a comprehensive study of petrology, geochemistry and isotopic geology data obtained by various units in this area in recent years, the authors believe that these granites and related metallogenic deposits and mineralization may be due to the Yanshanian cycle Platform blocks and the Dabie plate (old plate) collision, Dabie
