| 摘 要： | 通过对以往重磁数据重新处理，对以往不被人们关注，至少是少为人们关注的东北地区北西向构造有了新的认识.研究认为：东北地区北西向构造不仅大规模存在，而且还对东北地区的地质构造格架、东北地区的矿产资源的产出与分布都有着不可忽视的作用.讨论了北西向构造在重磁场上证据以及北西向构造的地质应力条件，证明北西向构造晚于北东向、北北东向构造，是一组独立的构造体系.

| Abstract: | By reprocessing the previous gravity and magnetic data, the paper gains a new understanding about the NW structures in Northeast China, which was ignored or less attended before. It is thought that such structures not only exist in large numbers, but also play important roles in the geotectonic framework and mineral resources distribution in the region. Based on the discussion of the NW-trending characteristics of gravity magnetic field and geological stress conditions, the structures prove to be a set of independent tectonic system later than NE and NNE structures. |
