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.

洋底是由岩浆注入沿大洋中脊的裂隙或扩张中心形成的，这一过程已持续发生了数百万年。在一些地方，大洋中脊被转换断层抵消了。通过鲜为人知的裂缝传播过程，扩张中心的几何形状随着时间的推移而缓慢变化。这项建议要求资金将最近关于传播裂缝的运动学的工作扩展到更一般的非变换偏移量的情况，以试图获得对山脊行为的描述。PI建议通过重复跳跃来扩展失败裂隙尖端的非稳定行为的模型，以包括重叠几何中的两个裂隙尖端可能的非稳定行为。目前的模型不能描述通常被称为重叠扩展中心(OSC)的偏移量，其中两个尖端似乎跳跃。
