【摘要】 集 2 0多个铜、多金属矿床的区域、矿带 (田 )、矿床不同比例尺的地质、地球化学勘查资料 ,研制了定量评价大矿异常的地球化学方法。在系统研究不同规模多种勘查尺度地球化学异常特征的基础上 ,初步总结了评价大型矿床的地球化学量化评价预测指标。更多还原

【Abstract】 Based on geological and geochemical exploration data of more than twenty copper and polymetallic deposits,including data of regional geology,ore belts(orefields)and ore deposits on different scales,the authors put forward the geochemical method for quantified appraisal of anomalies in large deposits.Through the systematic study of geochemical anomalies of different sizes,this paper has tentatively summed up geochemical quantified evaluation and predictin indices for appraisal of larg size ore deposits.更多还原
