洋壳活动断层特征和动力作用

对洋壳活动断层特征进行分析，认识到洋壳活动断层内存在洋壳生长，内部存在对称、褶皱和火山构造。洋壳生长不仅会形成新洋壳，而且会释放热量，产生推挤力，并在洋壳地形上留下演化痕迹。断层内部洋壳生长会促进断层两侧洋壳发生相对运动，众多洋壳断层活动的综合影响造成洋壳块体的相对运动。洋中脊是洋壳生长的产物，转换断层区域是洋壳块体现今相对运动的分界区带。

Characteristics and Dynamics of Active Oceanic Faults

Based on the characteristics analysis of active oceanic faults, we find oceanic crust growth, symmetrical structure, fold structure and volcanic structure in active oceanic crust fault. Oceanic crust faults not only release heat, but also create pushing forces that grow new oceanic crust and leave traces of evolution on the oceanic crust topography. The growth of oceanic crust inside the fault promotes the relative movement of oceanic crust on both sides of the fault, and the comprehensive influence of the activities of many oceanic crust faults causes the relative movement of oceanic crust blocks. The mid-oceanic ridge is the product of oceanic crust growth and the transform fault region is the boundary zone of current relative movement of oceanic crust blocks.
