六十年代发源于海洋构造研究的板块学说,把地球构造研究引进一个新的境界:建立了崭新的动态地球观。但在科学发展的思维长河中,人们又充分意识到解决大地构造问题的关键在于全面深入地探索大陆构造,意识到地质构造的多样式、多层次、多尺度、多成因的复杂属性。在转向大陆、多途径的探索中,微板块构造和相应的地体分析,又成为地学界瞩目的课题。北美西部是这种新思潮的主要发源地。本文以流畅的文笔描绘的带有科普性的“北美洲西部的增长”回答了我们思索中的一些问题,给我们以新的启示。
The plate theory originated in the study of ocean structure in the 1960s introduced the study of the earth structure into a new realm: the establishment of a completely new dynamic concept of the Earth. However, in the long process of scientific development, people are fully aware that the key to solving the problem of tectonics is to explore the continental tectonics in an all-round, in-depth and in-depth understanding of the multiform, multi-level, multi-scale and multi-generative complex features of geological structure. In the turn to the mainland, many ways of exploration, micro-plate structure and the corresponding terrane analysis, has become a subject of academic attention. Western North America is the main source of this new trend of thought. The well-documented “Growth in Western North America” portrayed in this essay as a fluent writer answers some of the questions in our thinking and gives us new insights.
