辽宁北部早古生代弧-陆碰撞作用的发现及其构造意义

DISCOVERY OF THE EARLY PALEOZOIC ARC-CONTINENT COLLISION IN NORTHERN LIAONING PROVINCE:Tectonic Implication

自然资源部中国地质调查局沈阳地质调查中心基础地质室构造研究团队在辽宁北部法库地区地质调查过程中,初步识别出了一次弧-陆碰撞作用.根据地质年代学研究,其主要发生在早古生代.该发现为华北板块北缘东段松辽盆地覆盖区的早古生代的构造演化史研究提供重要依据.

The research team from Shenyang Center of China Geological Survey,Ministry of Natural Resources,initially identified an arc-continent collision during the geological survey in Faku area of northern Liaoning Province.According to geochronology study,it is considered the collision occurred mainly in the Early Paleozoic.The discovery provides a significant basis for the study of Early Paleozoic tectonic evolutionary history of Songliao Basin coverage area in the northern margin of North China Plate.
