自从在阿尔卑斯山脉发现了海洋贝壳化石,人们便推测:阿尔卑斯山脉原先是一片浩瀚的海洋。随着在喀尔巴阡山脉、高加索、帕米尔、喜马拉雅山类似化石的发现,科学家们认为:整个阿尔卑斯——喜马拉雅山地带就是古地中海所在地。进一步研究结果证实了这种假设,最有力的证据就是现代岩石地台地质结构理论。根据这种理论,地壳由11块巨大地台构成,其变化速度极慢,每年仅几厘米,正是这种微弱变化导致了古地中海的变迁,从而产生了如今陆地上最大的山脉地带。 1982~1985年,苏联和法国科学家对
Since the discovery of marine shell fossils in the Alps, one has speculated that the Alps was originally a vast ocean. With the discovery of similar fossils in the Carpathians, Caucasus, Pamir, and Himalayas, scientists believe the entire Alps-Himalayas are the ancient Mediterranean. Further research confirms this hypothesis. The strongest evidence is the geological structure theory of modern rock platforms. According to this theory, the earth’s crust, made up of 11 huge platforms, whose rate of change is extremely slow, is only a few centimeters a year. It is this small change that has led to the vicissitudes of the ancient Mediterranean Sea, thus creating the largest mountain range on land today. From 1982 to 1985, the Soviet Union and the French scientists were right
