摘要
东秦岭钼矿带是中国著名的钼多金属成矿带,也是中国最大的钼矿基地与重要的矿集区之一。本文根据矿床成因、控矿构造、矿石成分及结构构造等,把东秦岭钼矿床分为两组八大类:斑岩-接触带型矿床、矽卡岩型矿床、斑岩-矽卡岩型矿床、斑岩-爆破角砾岩型矿床;破碎带型矿床、石英脉型矿床、韧性剪切带型钼矿床和碳酸盐脉型矿床,丰富了河南省内钼矿的类型。并选取有代表性的矿床进行了成矿地质特征和成矿时代研究,认为东秦岭钼矿的成矿年龄从1884±210M a^106.89±2.14 M a,把成矿时代空间从中生代扩展到了早元古代。
Molybdenum mineralization belt in east Qinling is one of the famous Mo polymetallic ore belt in China. It is also one of the largest Mo deposit bases and important ore fields. According to deposit genesis, ore-controlling structure, ore composition and texture, the Mo deposits in east Qinling are divided into two groups and eight types. They are porphyry-contact strip type, skarn type, porphyry-skarn type, porphyrybreccia type, fragment belt type, quartz vein type and tenacity shear type. This project enriches Mo deposit types in Henan province. Based on the study of the geological and mineralization features and date of representative deposits, it is proposed that the mineralization date is from 1884± 210Ma to 106. 89±2. 14 Ma. The mineralization age period extends from Mesozoic to early Proterozoic.
