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。
A geochemical method for quantitative evaluation of large-scale ore anomalies was developed based on geologic and geochemical exploration data of more than 20 copper and polymetallic deposits, ore belts (fields) and different scales of mineral deposits. Based on the systematical study on the characteristics of geochemical anomalies at various exploration scales in different scales, the prediction indexes of geochemical quantitative evaluation of large-scale deposits are summarized.
