【摘要】 在松南及南部邻区岩石圈中存在电性高导层,分布在壳内和幔内。高导层反应出岩石圈中拆离面、滑脱面以及流变塑性带的特性,也揭示出本区大陆壳幔结构。壳幔结构在本区不同地点的差异反映出深部软流圈、岩石圈和地壳的运动、演变过程。这一深部过程是本区中、新生代盆地形成的直接动力。更多还原

【Abstract】 High electrical conductivity layer distributed in crust and mantle exists in lithosphere in Southern Songliao Basin and its southern neighboring area. High electrical conductivity layer reflects characteristics of decoupling plane, detachment plane and rheological plasticity zone in lithosphere and reveals the structure of crust and mantle in the local continent. The differences of the crust and mantle structures in the different spots of this area show the movement and evolution process of deep asthenosphere, lithosphere and earth crust. This deep process is the direct dynamic power for formation of Ceno-Mesozoic Basins in this area.更多还原
