摘　　要：利用区域化探扫面 (水系沉积物测量 )资料 ,使用区域浓度克拉克值及变化系数两个参数 ,对福建省 32种元素的资源潜力进行了排序 ,认为在目前国家的导向矿种中 ,福建省的资源潜力依次为锌 -银 -铅 -锡 -金 -铜 -钼。同时根据谢学锦院士提出的地球化学块体的理论和方法 ,预测了政和 Au地球化学块体、龙岩中甲 Cu地球化学块体、大田 Pb地球化学块体的资源潜力 ,分别为金 430吨、铜 62 5万吨、铅 40 8万吨。初步探讨了成矿系统的元素分带及地球化学模式研究的意义和方法 ,认为这项研究对上述地区的找矿突破具有重要作用。Based on the data of regional geochemical stream sediment survey and the two geochemical parameters(the regional concentration Clarke values and their variation coefficients),the resource potential of 32 elements in Fujian Province has been collated and fell into place.It is considered that at present the potential mineral resources in Fujian Province are in the order of zinc→silver→lead→tin→gold→copper→molybdenum among the national oriented kinds of commodities.And according to the theory and method of geochemical block areas put forward by Xie Xuejin who is an academician of Chinese Academy of Sciences,it is deduced that the potential mineral resources of three geochemical block areas(the gold geochemical block area in the Zhenghe area,the copper geochemical block area in the Longyan area,the lead geochemical block area in the Datain area)are 430 tons of gold,625 tons of copper and 408 tons of lead,respectively.Finally the author made the discussion of the zoning of geochemical elements in the metallogenic system and the significance and method of studying the geochemical model,which is of importance to hunting for ores in the above mentioned area.
