摘要
利用地球化学块体的理论和方法,在矿产勘查中能达到“迅速掌握全局,逐步缩小靶区,靶区能在全局之中相互比较”的目的;江西省在10km×10km的窗口上发育鄣公山—德兴、进贤、宜春、银坑4个Au地球化学块体,每个块体具有不同特点的地球化学模式谱系;在分析块体成矿地质特征的基础上,利用地球化学成矿率对块体的资源潜力进行了预测。
Employing the theory and method of geochemical block,it is possible to attain the purpose of“to quickly have an overall view of the whole study region,to diminish gradually the area of maximum interest where the targets are to be localized,and to compare between the various targets of the whole region”.Based on a10km (10km window method,four Au geochemical blocks have been delineated in Jiangxi namely the Zhang-gongshan-Dexing,the Jinxian,the Yichun and the Yinkeng Blocks,each of which has different characteristics and geochemical model hierarchy from the others.Based on an analysis of the metallogenic geologic characteris-tics of the blocks,a prediction of the resource potential has been made using a geochemical mineralization index.
