二连盆地早燕山期构造体制及原型盆地推测
|
摘要
本文在已有区域地质调查成果的基础上,通过钻井资料分析和三维地震资料的构造解析,确定二连盆地区及周缘侏罗系的分布存在两种型式:"叠合型"和"非叠合型",其中前者分布在二连盆地区内;后者分布在盆地北部区域(以乌里雅思太凹陷为代表)和盆地周缘的露头区,并受"三纵四横"构造格架的控制。二连盆地区早燕山期处在南北向挤压和滨太平洋弧后构造体制的转折期,其中弧后构造体制起主要作用,南北向挤压构造体制主要以先存构造的方式发生作用。早燕山期存在两类盆地,"叠合型"侏罗系组成的"内二连盆地"具有裂陷盆地性质;"非叠合型"侏罗系组成的"外二连盆地"推测是具有弧后背景的类克拉通盆地。
Based on regional geological surveys,drilling data and structural analysis of 3D seismic data,two distribution modes of the Jurassic has been identified in and around Erlian basin area: "superimposed type" and "non-superimposed type".The former is distributed mainly within the Erlian basin area,while the latter is mainly in the north(represented by Wuliyasitai sag) and around the Erlian basin,and is subject to the constraint of" three vertical and four horizontal " tectonic frameworks.The Erlian basin was in a transition between N-S compression and back-arc tectonic regime of the western Pacific during the Early Yanshanian period,in which the back-arc tectonic regime played a leading role and the compression set up a spatial preparation for mineralization.There were two types of basins in Early Yanshan Era: internal Erlian basin composed of "superimposed type" Jurassic is characterized by nature of rifting basins,and external Erlian basin composed of "non-superimposed type" Jurassic is presumably atypical cratonic basin formed in the backarc setting.
