北大西洋Mohns洋中脊扩张地壳构造特征的研究

Study on the characteristics of crustal structure in Mohns ridge expansion in the North Atlantic

北大西洋Mohns洋中脊是很重要的扩张带。中国第五次北极科学考察的重点之一就是获取Mohns洋中脊的磁力数据。通过获得的磁力和以往的重力与地震资料,研究洋中脊的扩张、地壳构造特征及厚度。这些研究有助于更好地理解地球上重要的地质过程、海底扩张和壳幔相互作用。

Mohns ridge in the north of Atlantic Ocean is a very important expansive band.One of the key for the Fifth Chinese National Arctic Research Expedition is to acquire the magnetic data on Mohns ridge.According to the magnetic,gravity and seismic data,the Mohns ridge expansion,characteristics of crustal structure and thickness are researched.These studies contribute to better understanding of the earth＇s geological process,seafloor spreading and crust mantle.
