松辽盆地北部深部地质特征研究
|
摘要
应用松辽盆地深部地震剖面信息探讨盆地深部地壳的组成、特性及盆地形成的地球动力学过程。在地震剖面上将盆地地壳划分出四个圈层构造。探讨了盆地内深部的软流圈上隆、壳—幔相互作用、拖网结构、地壳减薄、拆离带等地质作用对浅部断陷和坳陷的形成和演化的控制机理。深化了对松辽盆地深部地质结构和深层断陷盆地形成演化机制的认识。为深层可燃矿产资源进一步勘探提供了较为系统的理论依据。
Seismic data is applied to investigate the deep crust structure,geological features and the formation kinematics of the Songliao Basin.The crust within the basin is divided into four lithosphere types based on seismic sections.This paper discusses the effect of tectonics such as uplifting of the asthenosphere in the deep basin,the interaction between the crust and the mantle,the net structure,crust thinning and the detaching zone on the forming and evolving mechanism of the shallow rift and faults,providing a clear view at the deep geologic structures of Songliao Basin and at the forming and evolving mechanism of deep rifted basins.At the same time,the results help establish a systematic theoretical model for further deep exploration for hydrocarbons.
