CHEN 9300512 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.

陈9300512，这项研究的目的是了解大洋中部三维地形受海脊分段产生的各种载荷力控制的具体机制。在研究的第一阶段，将开发一个新的三维山脊热模型，其中将包括与地壳定位沿轴变化有关的热输入、地壳热液冷却以及跨裂谷和转换槽陡峭墙壁的横向热传递。在第二阶段，将检验所观察到的隆起形态是由三维岩石圈变形产生的假设。在第三阶段，理论模型的结果将与大洋中脊四个勘测区域的数据进行比较。
