中文摘要
洋底是由岩浆注入裂谷或沿洋中脊扩散中心形成的,这一过程已经持续了数百万年。在某些地方,洋中脊被转换断层所抵消。扩展中心的几何形状随着时间缓慢变化,这是由于人们对裂缝传播过程知之甚少。该提案要求基金将最近关于传播裂缝运动学的工作扩展到更一般的非变换偏移情况,以试图获得山脊行为的描述。PI建议通过重复跳跃来扩展失效裂谷尖端的非稳态行为模型,以将重叠几何结构中两个裂谷尖端的可能非稳态行为纳入其中。目前的模型不能描述通常被称为重叠扩散中心(OSC’s)的偏移,其中两个尖端似乎都跳跃。
英文摘要
The floor of the ocean is formed by the injection of magma into rifts or spreading centers along the mid-ocean ridges in a process that has been continually occurring for millions of years. In places the mid-ocean ridges are offset by transform faults. The geometry of spreading centers changes slowly with time through poorly understood processes of rift propagation. This proposal requests funds to extend recent work on the kinematics of propagating rifts to the more general case of nontransform offsets to try to obtain a description of ridge behavior. The PI's propose to expand a model of the nonsteady behavior of a failing rift tip by repeated jumps to incorporate possible nonsteady behavior by both rift tips in an overlapping geometry. present model cannot describe the offsets commonly known as overlapping spreading centers (OSC's) where both tips seem to jump.
