按照大洋钻探计划,第147航次是在太平洋东部东太平洋海隆赤道部分的范围内进行的。 本航次的主要目的是在自然对象中核实洋中脊地壳的各种形成和成层模式,以及恢复在上地幔和地幔一地壳过渡区中进行的地质过程。解决这些问题不仅对弄清具有不同扩张速度(据地球物理资料,推测沿扩张轴存在着不同形态和埋藏深度的孤立岩浆层,它影响了海
In accordance with the Ocean Drilling Program, voyage 147 was carried out within the equatorial part of the eastern part of the Pacific Rim of the Pacific Ocean. The main purpose of this voyage is to verify in various natural formations various forms and stratigraphic patterns of the mid-oceanic ridge crust and to restore the geological processes that took place in the transitional region of the upper mantle and the mantle-crust. Solving these problems not only makes it clear that there are different rates of expansion (based on geophysical data, it is presumed that there are different magma formations with different morphologies and burial depths along the axis of expansion that affect the sea
