概述 J.C.Maxwell(得克萨斯州大学地质系) 过去的20年是历史上一个光芒四射的探测时代。人们进入了两个巨大而实际上未知的领域,这就是占地表70％的大洋底部和宇宙空间。这些探测计划的发现,重新确定了地质学的思维方向。相对平静的地球观已为水平运动达数千公里的“板块构造”的动态地球观所代替。 Overview J.C. Maxwell (Department of Geology, University of Texas) The past two decades have been a glorious history of exploration. People have entered two huge and virtually unknown areas, which are the bottom of the oceans and the cosmos that account for 70% of the Earth’s surface. The discovery of these exploration plans has redefined the thinking direction of geology. The relatively calm view of the Earth has been replaced by a dynamic Earth view of “plate tectonics” that moves horizontally for thousands of kilometers.
