详细研究了七段、约130km长的近垂直反射地震剖面所揭示的松辽盆地下的壳幔结构。松辽盆地之下壳幔之间为相对厚的Moho过渡带。可分为薄Moho和透镜状Moho以及过渡型Moho,与之对应的壳幔结构也有差异。松辽盆地的发育阶段明显地可分为断陷期、拗陷期以及夭折期,不同的壳幔结构可能与松辽盆地不同的发育期存在密切联系。此外,通过对比,认为裂谷盆地区具有类似的特殊壳幔结构。在裂谷区,壳幔之间强烈相互作用,不同的地壳组成和裂谷形成的不同阶段是形成不同壳幔结构的主要原因,而且它们之间具有成因上的联系,并与裂谷的形成阶段相一致。
The structure of crust and mantle beneath the Songliao Basin as revealed by the Seismic Profile of the nearly vertical section of about 7 km and about 130 km long has been studied in detail. The relatively thick Moho transitional zone between crust and mantle beneath the Songliao Basin. It can be divided into thin Moho and lenticular Moho and transitional Moho, corresponding to the crust structure. The developmental stages of the Songliao Basin are clearly divided into faulting, depression and ablation. Different crust-mantle structures may be closely related to the different developmental stages of the Songliao Basin. In addition, by contrast, the rift basin region is considered to have similar special crust-mantle structure. In the rift area, strong interaction between crust and mantle, different crustal composition and different stages of rift formation are the main reasons for forming different crust-mantle structures, and they are genetically connected with formation of rift The same phase.
