虹螺山—五指山地区钼矿床成矿地质条件与成矿规律
|
摘要
虹螺山—五指山地区的八家子—杨家杖子成矿带是华北地台北缘一条重要的多金属成矿带,也是我国第二大钼成矿带。本区钼矿床类型包括斑岩型、斑岩—矽卡岩型、矽卡岩型和石英脉型。本文在前人研究成果的基础上,以典型矿床为切入点,应用岩石学、矿床学、稀土元素地球化学的基本原理,对区内钼成矿带区域地质背景、矿床地质特征和控矿因素进行了系统全面的研究,指出岩浆活动和断裂构造是钼成矿的主要控矿因素。在此基础上,根据对区内岩石矿化和蚀变类型的研究,结合对室内图件的编制和数据处理结果的综合分析,总结出钼矿床的产出总体受北东向构造岩浆岩带控制且有水平或垂直分布的成矿规律,为今后区内的找矿工作起到了指导作用。
Hongluoshan-Wuzhishan area is an important metallogenic belt for Mo on the northern margin of the North China Block and is also the second largest Mo metallogenic belt in China. The deposit types mainly include porphyry tapes, porphyry–skarn tapes, skarn tapes and quartz vein tapes. Base on the results of the previous researchs, it selects the typical deposits as an entry point, then with the application of the basic principles of petrology, mineral deposits and REE geochemistry. It has a detail study to the regional geological setting of the molybdenum metallogenic belt, geological characteristics and ore-controlling factors, pointing out that the magmatic activity and fault structures are the main controlling factors. On this basis,according to the research of the rock mineralization and alteration types, combined with the comprehensive analysis to the establishment of indoor maps and the results of data-processing, summing up the regularity that the molybdenum deposit is controlled by the NE tectono-magmatic belt and it has a trending of horizontal or vertical distribution , this will play a guiding role in the future exploration work .
