一、古海洋学的内容古海洋学即海洋古地理学,是七十年代中期发展起来的一门边缘科学.它研究海洋古环境和海洋地质历史,目的是要重建2亿年(侏罗纪)以来海洋古环境的变化历史.古海洋学的研究不但有巨大的理论价值,而且有重的经济意义.海洋面积占地球表面积的70%以上,很明显,没有古海洋学的深入研究,要了解地面的古地理演变是不可能的.而且海洋轮廓及洋流的变化极大地影响大陆的气候,例如,第三纪古特提斯海
1. The Content of Paleoceanography Paleo-oceanography, or marine paleography, is an edge science developed in the mid-1970s and aims to study the history of marine paleoenvironment and marine geology in order to reconstruct 200 million years (Jurassic ) Since the ancient oceanographic changes in the history of paleo-oceanography is not only of great theoretical value, but also has a heavy economic significance.Ocean area accounts for more than 70% of the Earth’s surface area, it is clear that no in-depth study of paleo-oceanography It is impossible to understand the paleogeographic evolution of the earth’s surface, and the changes in the ocean’s contours and currents greatly affect the continental climate, for example, the Tertiary
