摘　　要：应用分量化探法对粤北长排地区进行了找矿前景预测评价，圈定出贯穿测区南北的3条铀分量异常带。3条异常带在测区北部连成一片面积较大的异常区，并在该异常区内钻探到多个工业铀矿体，取得了较好的研究成果。建立了4条分量化探法勘查花岗岩型铀矿的地球化学找矿标志。分量化探法将在“攻深找盲”、寻找“第二找矿空间”等铀矿勘查方面发挥更大的作用。Partial extraction geochemical prospecting method was used to evaluate the uranium minerali-zation prospect and three uranium abnormal zones was outlined from north to south and joining together in the north of Guangdong.Satisfied prospecting results and several industrial uranium drilling holes have been obtained in the big uranium abnormal area by drilling.4 geochemical prospecting indicaters were de-veloped for the exploration of granite type uranium deposit by partial extraction geochemical prospecting method,which will play a more important role in the uranium exploration of deep buried ore and second prospecting space.
