新编亚洲大地构造区划图

摘要:
提要:在大量综合亚洲地质、地球化学与地球物理资料的基础上,笔者新编了亚洲大地构造区划图,确定了划分原则,将亚洲大陆划分为六大构造域,以及67个板块(或地块)、碰撞带或增生碰撞带,并以此为基础进行了图件的编制。组成亚洲大陆的板块或地块主要形成于1800 Ma、800 Ma、 500 Ma 和400 Ma前后,上述时期即各地块形成统一结晶基底的时期。碰撞带或增生碰撞带形成时期较多,为800 Ma、397 Ma、345~260 Ma、200 Ma、135 Ma、52 Ma和23 Ma等,还有23 Ma以来形成俯冲带。对于资料比较充实的、古生代以后的板块运移、板内变形与碰撞带的形成过程进行了概略的讨论。本文还关注了在地块形成之后的板内变形。正是板内变形阶段,可能对成矿作用及其类型、过程与赋存部位产生重要的影响。

Abstract:
Abstract:Based on abundant geological, geochemical and geophysical data of Asian continent, the author compiled a new Asian tectonic unit map, determined the principle of division, and divided Asian continent into six tectonic domains as well as sixty-seven plates (or blocks) and accretion collision zones (or collision zones), and then compiled the tectonic unit map. The plates or blocks of Asian continent were mainly formed at about 1800 Ma, 800 Ma, 500 Ma and 400 Ma,which were the periods to form the unified crystallization basement. There existed quite a few formation periods of collision zones or collision accretion zones, which occurred in 800 Ma, 397 Ma, 345~260 Ma, 200 Ma, 135 Ma, 52 Ma and 23 Ma respectively;in addition, subduction zones have been formed since 23 Ma. With abundant data on geological activities since Paleozoic, this paper discusses roughly the plate migration as well as the formation of intraplate deformation and collision zones during that period. The author has paid special attention to the intraplate deformations of that period, which made many great influences on types, processes and occurrence positions of metallization.
