洋中脊正断层的几何形状Ｔ．Ａ．Ｍｉｎｓｈｕｌ等正断层在缓慢扩张的洋中脊轴部地形中有重要意义，也是确定深海丘陵形态的主要因素。微震和远震的证据表示存在延伸到地壳和上地幔中中等倾角（３０°～６０°）的洋中脊断层（Ｔｏｏｍｅｙ等，１９８５）。从潜水器中已发... Mid-ocean ridge normal fault geometry. A. The normal faults such as Minshul are of great significance in the slowly expanding mid-ocean ridge axis topography and are also the main factors for determining the morphology of deep-sea hills. Microseismic and teleseismic evidence suggests that there are mid-ocean ridge ridges extending to the mid-dip (30 ° to 60 °) in the crust and the upper mantle (Toomey et al., 1985). Has been sent from the submersible ...
