摘　　要：开展江西田村圩地区遥感地质解译,提取区域地质构造、侵入岩体、地层及蚀变信息,初步剖析测区典型矿床矿化遥感蚀变信息特征;提取研究区遥感成矿、控矿条件,开展区域成矿远景研究。依据离子吸附性稀土矿的成矿规律,综合遥感地貌解译和风化特征矿物异常信息提取结果,圈定5处稀土矿遥感找矿预测区。尝试建立石英脉型钨矿的遥感找矿预测模型,圈定钨矿找矿远景区4处,为区域地质调查工作提供找矿线索。This paper develops geological interpretation with remote sensing,extracts the information of regional geological structure,intrusive rocks,strata and alteration in Tiancunxu area of Jiangxi Province,and analyzes remote sensing and alternation features of typical deposits and mineralization of the study area. It also extracts metallogenic and ore-controlling conditions with remote sensing in the survey area,and carries out regional metallogenic prospecting study. Based on the metallogenic regulation of ions adsorption rare earth deposit,and considering the extracting results of remote sensing geomorphic interpretation and weathering mineral abnormal information,it delineates 5 rare earth mine predicting areas with remote sensing. It also tries to establish a remote sensing mineral predicting model of quartz-vein-type tungsten deposit,and has delineated 4 prospecting areas of tungsten ores,which provides clues of ore prospecting for regional geological survey.
