摘　　要：班公湖—怒江结合带是青藏高原上几条主要的NW走向缝合带之一,对区域构造演化与成矿均具有重要的控制作用。本文选择结合带中段的西藏那曲地区,利用ETM遥感数据,结合重点地段的雷达影像资料及野外调查结果,解译确定了各次级构造单元的分界深大断裂,并将该区划分为5个次级构造单元,较系统地分析研究了各次级构造单元的遥感地质特征、成矿地质环境和找矿有利条件,为该区基础地质研究与找矿勘查提供参考和依据。The Bangong lake-Nujiang suture zone is one of the main NW strike suture zones on the Tibetan Plateau,it plays an important role in controlling regional tectonic evolution and ore-forming.This paper selectes the Naqu region of Tibet in the middle suture zone,using ETM remote sensing data,combined with Radar image data and field survey results of key sections,determines boundary deep-large faults of each secondary structural unit by interpreting,divides the region into 5 secondary structural units,and systematically analyzes and studies the remote sensing geological characteristics,ore-forming geological environment and favorable conditions for prospecting of each secondary tectonic unit,provides reference and basis for basic geology research and prospecting exploration in this region.

关 键 词：分界深大断裂 构造单元分区 遥感地质特征 那曲地区
