苏鲁造山带深部构造的接收函数图象
|
摘要
宽频地震探测获得横切苏鲁造山带的滨州-日照剖面和蓬莱-青岛剖面的接收函数图象。在图中识别出一系列密度界面和断裂面。新Moho面深度35～41km,形态清晰连续完整,表明苏鲁造山带形成以来的壳幔相互作用已经相当彻底。苏鲁造山带和胶辽朝地块的岩石圈底面深度105km,靠近郯庐断裂逐渐抬升到90km。在苏鲁造山带内部识别出了造山过程中形成的构造界面。它们所勾画出的深部构造图案支持扬子板块拖带北中国板块边缘深俯冲剥蚀模型,并且指示苏鲁超高压变质带的北界位于莱西一线的胶莱盆地之下。
We use broadband seismic exploration to get the receiver function image along the array from Bingzhou to Rizhao and the array from Penglai to Qingdao, which transversely cut Sulu orogenic belt. A series of density interfaces and Faults are identified in the image. The depth of new Moho is 35～41km. The new Moho is clear, continuous and whole, that indicates the crust-mantle action has been quite thorough since Sulu orogen forming. At Sulu and JLKB, the underside of lithosphere is 110km depth, and near TLF, it uplifts to 90km depth. In Sulu Orogen, some structural interfaces formed in orogeny are identified. The deep structure pattern outlined by these interfaces supports the deep subduction erosion model, that the edge of the North China Plate is dragged downward by YZP, and instructs that the north bound of Sulu UHPM is under Jiaolai basin at Laixi.
