从板块构造到地体

From Plate Tectonics to Terrane Concept

从板块构造的发生、发展到地体概念的提出 ,论述了地体解析和拼贴构造 ,并根据中国东部的地体研究 ,特别是中国东北那丹哈达地体和日本美浓地体的对比研究 ,论述了亚洲东部中生代构造发展史 ,认为在侏罗纪时 ,亚洲大陆边缘的地体拼贴活动已经开始 ,形成了拼贴沉积的复合地体 ;白垩纪时由于大陆边缘的侧向挤压和离散作用 ,这些地体产生左行运动和变形 ;早第三纪晚期由于日本海的扩张 ,形成了弧形的日本列岛。

This paper discusses the terrane parse and matching tectonics form the occurrence, development of plate tectonics to the emergence of terrane concept. Based on the research on east China terranes, especially on the comparative study between Nadanhada terrane and Mino terrane in Japan, it also discusses the Mesozoic tectonic history of east Asia. It is believed in the paper that the terrane of Asia continental margin had begun to mathch in Jurassic, and formed the match-deposit composed terrane; Because of the lateral compression and divergence near continental margin in Cretaceous period, these terranes moved sinistrally and deformed; In the late eogene, because of the expansion of Japan sea, the arcual Japanese Archipelago formed.
