吉林省地质局物探大队自八十年代初以来,对吉林省及邻区的六十万km~2247339个数据的国家重力及航磁测资料,在M-160Ⅱ电子计算机上进行了计算处理.利用压缩质面法计算出相应的莫霍面深度,与已知的地壳厚度进行拟合优度计算.最后选取了拟合优度较高、信息又较丰富的60公里X60公里的富口圆滑布伽重力异常,并对松辽平原地 Geophysical Brigade of Geological Bureau of Jilin Province has computed and processed the national gravity and aeromagnetic data of 600,000 km ~ 2,247,339 data of Jilin Province and its neighboring areas since the early 1980s on M-160Ⅱ computer. Compressive mass spectrometry method to calculate the corresponding Moho depth, and the known crustal thickness for goodness of fit.Finally, the selection of a higher goodness of fit, the information is rich in 60 km X60 km rich mouth smooth cloth Gravitation anomalies, and Songliao plain
