摘要
东北亚地区，地理跨度大约于北纬３０－４５°范围内的中国东部与朝鲜之间，地学领域中存在着大地构造单元重建问题。其区域背景正处于亚洲大陆边缘变动带，涉及中朝，下扬子和华南三大块体的构造演化和发展。近年来，胶东地块及其邻域的大地构造相（Ｔｅｃｔｏｎｉｃｆａｃｉｅｓ）分析，包括造山碰撞作用、混杂岩（Ｍｅｌａｎｇｅ）形成机制以及地块属性等作了深入的研究，取得了突破性进展。在此基础上，开展区域连接对比，提出了厘定本地区大地构造对应划分的意见。
Northeast Asia geographically covers eastern China(3O-45N)and Korea,and fromthe view point of geology ,it is very necessary to reconstruct the geotectonic units.Northeast Asia is situated in the Asian continental marginal mobile zone,involving Sino-Korean Platform,Lower Yangtze Platform and South China Platform,its structural evo-lution is considerable complicated.In recent years,investigations and studies have been made carefully on tectonic fa-cies of Jiaodong Massif and the adjacent areas,mainly on orogenic collision,the forma-tion mechanism of melange,the massif attribution and the Late Paleozoic fossils. Strikingprogress has been made in the study.This paper will discuss the following four subjects on the basis of the knowledge ofthe melange evolution history.
