【摘要】 <正> 很多学者对本文所讨论的地区的构造,从各种不同观点进行过论述。作者谨按板块构造说再次进行讨论。讨论以1975年8月出版的中国地质科学院编1:500万亚洲地质图和1979年1月出版的黑龙江省区域地层表编写组所编东北地区区域地层表黑龙江省分册为基础,以K.C.Condie(1976)著 Plate tectonics and Crustal evolution 和 J.B.Wright 编辑的 Mineral deposits,Continental drift and Plate tectonics(Benchmark papersin Geology/44)(1977)为主要工具书。但若干较新资料和上述图、表的有关部份不同,现摘要罗列如下:更多还原

【Abstract】 The Palaeozoic orogeny belt in Heilongjiang river basin can be interpreted in terms of the following simplified platetectonic history: (a)perfect epicon-tinental sea during the Early Cambrian, Middle Cambrian opening of ocean between Siberian and North China, (b) development of eastward-dipping subduction system during the Early Ordovician, (c) the Taconic Orogeny of activation - type in the Late Ordovican, (d) start of a continent - continent collision (Siberian - Nor th China) in the Late Silurian, occurrence of the Acadian Orogeny in the west of the region, (e) an activation - type and arc-arc collision orogeny (the Antler Orogeny) and suture zone occurred in the Early Carboniferous involving principally eastward directed thrusting, (f) development of rift system and the Appalachian Orogeny from the Late Carboniferous to Late Permian.The paper also discusses the relationship mineral zone and tectonics.更多还原
