海洋地质是当代地球科学发展的重要前沿学科,海洋地质的研究对发展地球科学具有重要理论意义和实用价值。长期以来,地球科学研究的重点是陆地,这是因为受到当时技术条件的限制难以开展海洋方面的工作,也因为过去人们对海洋研究的重要性估计不足。大家知道,海洋占地球总面积的2/3以上。因此,要全面地揭露地球内在的规律及其演化历史,不能不重视海洋科学的研究。自从60年代板块学说兴起之后,新的地球观、构造观应 Marine geology is an important frontier discipline in contemporary earth science development. The study of marine geology has important theoretical and practical values ​​for the development of earth science. For a long time, the focus of geosciences research has been on the land. This is because it was hard to carry out the ocean work due to the limitations of the prevailing technical conditions at that time. In the past, the importance of marine research was underestimated. As we all know, oceans account for more than two-thirds of the Earth’s total area. Therefore, to fully reveal the inherent law of the Earth and its evolution history, we can not but pay attention to the study of marine science. Since the rise of plate theory in the 1960s, a new outlook on earth has been constructed
