摘　　要：通过对长江中下游地区1∶20万金元素不同尺度数据的地球化学特征响应的研究,认为长江中下游存在地球化学巨省,这个地球化学巨省为长江中下游地区提供源源不断的矿源。同时,讨论了低密度地球化学方法能够用于全国或全球地球化学填图的可行性。Based on a study of the geochemical characteristics response of different scales of gold element data from 1∶200000 geochemical survey in the middle-lower reaches of the Yangtze River,the authors hold that there exists a giant geochemical province in the middle-lower reaches of the Yangtze River,which has continuously provided ore sources for the middle and lower Yangtze River areas.The feasibility of applying the low-density geochemical method to whole China or the whole world is also discussed in this paper.
