| 摘 要： | 将羌塘盆地的航空磁场按不同的异常面貌特征分成八大区进行了详述描述。羌塘盆地航空磁场的展布总体以东西向或近东西向为主，其次为北东向和北西向，随着向上延拓高度的增加，该特征更加明显，磁异常具有鲜明的分区性和分带性，且从北向南异常由平稳到复杂逐渐变化，这些特征是羌塘盆地特有的地质构造和磁性岩石空间组合状态的综合反映。

| Abstract: | In Qiangtang Basin,the major spreading direction of aeromagnetic anomaly is EWor approximately EW,while the minors are NW and NE.The inverse height added up,this tendency appears clearer than measured height.The anomalies change slowly southward from simple to complex.Whereas the planar shapes of the anomaly seem to be zonal or lumpish.These characteristics reflect composite state among the tectonic fabric and subsurface magnetic rocks.Hence,this paper presents the aeromagnetic anomaly characteristics in detail by dividing the aeromagnetic field of the basin into 8 districts according to different anomaly characteristics. |
