对海洋年龄的探讨,科学家们曾作出过多次的尝试。现在仅选择其中有代表性的而又曾一度为学者所赞赏的方法概述于下。 1.沉积物法海滨的拍岸浪,不断地、猛烈地拍击着崖岸,起着破坏的作用,把大批的碎裂物质卷入海洋中。注入大海的江河,每年也把大量的泥砂运往海里去。这样就不断地增加着海洋沉积的厚度。海底的沉积物受了强大压力的作用,渐渐转变为致密而坚硬的岩层,这种岩层叫做沉积岩。观测指出,在 The age of the ocean, scientists have made many attempts. Now only a selection of representative and once appreciated by scholars for the method outlined below. 1. Sediment Law Beach shore waves, constantly, violently slapped the cliffs, playing a destructive role, a large number of fragmented material involved in the ocean. Into the rivers of the sea, each year also put a lot of silt transported to the sea. This continues to increase the thickness of marine deposits. Submarine sediments under the strong pressure of the role, and gradually transformed into a dense and hard rock, this rock is called sedimentary rock. Observations indicate that at
