板块理论不是根据大陆地质(大陆只代表地球历史早期活动幕的残余碎块)的研究结果发展起来的,而是对大洋下地球表面3/2的,正在进行的板块构造基本作用过程的观察结果发展起来的。可以认为,海洋地质学和地球物理研究正处于广泛活动、迅速发展和普及时期。这种形势促成立了联合海洋学机构 JOI,由美国十个海洋研究部门组成和领导的非盈利合作机构,委派一个积极从事海洋地质学和地 Plate theory was developed not based on the findings of continental geology (the continent represents only the remnants of the Earth’s early curtain of activity), but rather the observations of the fundamental process of ongoing plate tectonics, 3/2 of the earth’s surface beneath the oceans Developed It can be argued that marine geology and geophysical research are in widespread activity, rapid development and popularity. This situation led to the establishment of a joint oceanographic institution JOI, a non-profit cooperation organization comprising and led by the United States’ 10 marine research institutes, which has assigned a delegation to actively engage in marine geology and geology
