Discussion on the crustal density distribution and deep crustal structure of the super-long profile from Mandula (Inner Mongolia) to Kachujia (Russia)

Using the gravity anomaly dataset of the 1320 km long profile from Mandula (Inner Mongolia) in the south, through Mongolia to the Kachujia (Russia) in the north of Baikal, the 2D crustal density structure model has been constructed in this study. We have analyzed the deep structural features along with the Moho interface of the profile including the gravity anomaly, the crustal density structure, the interface undulation and fault distribution for each tectonic unit. This result can provide the proof of gravity field for the further understanding of the crustal structure of the area across the profile, the boundaries and correlations of tectonic units, and the related continental dynamics.
