摘　　要：自2000年以来,在提高了区域重力调查技术要求,更新了区域化探方法技术后,极大地提高了东北地区基础地质工作程度,发现了众多重力异常,圈定和推断了隐伏岩体、盆地和断裂构造.特别是区域化探,获得的地球化学异常更加丰富,真实地反映了地质规律,提供了较多的成矿远景区和找矿靶区,发现了众多矿产地.首次开展的多目标区域地球化学调查,查明了松辽平原土壤元素区域地球化学分布特征,证实了松辽平原土壤环境质量是优良的.这些成果为东北地区的地质工作提供了丰富的地球物理和地球化学基础信息.Since 2000, with increased requirements for regional gravity survey technique and renewed regional geochemical exploration methods and technology, the level of basic geological work in Northeast China has greatly improved and many gravity anomalies have been found. Concealed rocks, basins and faults have been delineated and inferred. Especially through the regional geochemical exploration, abundant geochemical anomalies have been recognized, which reflect the true geological rules, provide more metallogenic prospective areas and target areas and find many mineral deposits. With the first round of multi-purpose regional geochemical survey, the regional geochemical distributions of soil elements are ascertained.The soil environment in Songliao Plain is confirmed as good quality. These results provide abundant geophysical and geochemical information for the geological work in Northeast China.
