摘　　要：本文重点总结赣西北地区修水县联测图１∶５万区调取得的主要进展与区调方法上的创新。其中，在中元古界双桥山群浅变质岩系中所识别、填绘出的近东西向紧闭同斜倒转褶皱，叠加近南北向开阔圆滑褶皱，在中小型陆相红盆中探索出的运用数理统计与沉积学研究相结合确定冲积扇体，并用扇体与岩性段双重方法予以图面表达以及第四纪研究成果等取得的重要进展。此外，就有关提高区调质量等问题浅谈其体会。This paper summarizes mainly the major progress of the combined mapping group in 1:50 000 regional geological survey in Xiushui County of Northwest Jiangxi and the innovations made in regional geological survey method, including the nearly E-W trending closed homoclinal overturned folds superposed by N-S trending open smooth folds established in the Mid-Proterozoic Shuangqiaoshan Group epimetamorphic rock system, the alluvial fans in medium-sized and small-sized red basins determined by mathematical statistics in combination with the sedimentological methods, the expression of the fans in the map by both fan geometry and lithologies, and also some research results on Quaternary geology. This paper also discusses how to improve the quality of regional geological surveying.
