LIN 9300708 The object of this study is to understand the specific mechanisms in which the 3-D mid-ocean topography is controlled by various loading forces arising from ridge segmentation. In the first phase of the study, a new 3-D ridge thermal model will be developed that will include heat input associated with along-axis variations in crustal emplacement, crustal hydrothermal cooling, and lateral heat transfer across the steep walls of rift valleys and transform troughs. In the second phase, the hypothesis that the observed ridge morphology is generated from the 3-D lithospheric deformation will be tested. And in the third phase, the results of the theoretical models will be compared with data from four well surveyed areas of the mid-ocean ridge.

LIN 9300708这项研究的目的是了解3-D中部地形受到脊分割产生的各种载荷力控制的特定机制。在研究的第一阶段，将开发出一种新的3D脊热模型，其中包括与轴轴相连的轴轴变化相关的热输入，地壳水热冷却以及横向穿过裂谷谷的陡峭壁的侧向热传递和转化槽。在第二阶段，将测试从3D岩石圈变形产生观察到的脊形态的假设。在第三阶段，将将理论模型的结果与来自海洋中部山脊的四个经过良好调查区域的数据进行比较。
