| 摘 要： | 横穿诸城凹陷的南北向反射地震剖面揭示,苏鲁造山带北侧边界的中上地壳中存在着三层结构,即上部的胶莱盆地沉积盖层、中部的苏鲁楔状地体和下部代表华北板块的胶北地体;诸城凹陷边缘和内部断裂均显示同沉积正断层性质,苏鲁楔状地体中发育一组向北仰起的叠瓦状逆冲断层,而胶北地体显示了向南俯冲的态势.由此而论,可能存在着华北板块与扬子板块相向俯冲于苏鲁地体之下的陆陆碰撞机制,苏鲁地体可能具有与大别地体相似的花状造山带结构.

| Abstract: | Three layers are present in the middle and upper crusts in the northern border of Sulu orogenic belt, as revealed by the S-N-strike reflecting seismic profiles that cross the Zhucheng sag. These three layers are the uppermost sedimentary cover of Jiaolai basin, the Sulu sphenoid terrane in the middle layer and the Jiaobei terrane representing North China plate at the bottom. The fringe of Zhucheng sag and the interior fault are characterized by the syndeposit normal fault. A group of imbricated reverse thrust facing upward to the north has developed in Sulu sphenoid terrane, but the Jiaobei terrane has the trend of subducting to the south. As a result, a collision mechanism is perhaps present between continents where North China plate and Yangtze plate subducted to each other below the Sulu terrene which has the same flower-shape orogenic structure as that of Dabie terrane. |
