| 摘 要： | 京津晋冀地区是华北板块的主体,该区寒武系第三统以鲕粒灰岩的广泛发育为特点。通过野外露头剖面和室内薄片观察,对研究区鲕粒灰岩空间展布和鲕粒类型进行了详细研究。鲕粒灰岩从东到西出现的层位逐渐抬高,具有明显的穿时性。大型鲕滩呈向西凸出的弧形带状分布,鲕滩带主体由同心鲕鲕粒灰岩组成,鲕滩带西侧鲕粒灰岩厚度迅速减小,鲕粒以放射鲕...

| Abstract: | The study area,geographically including Beijing,Tianjin,Shanxi and Hebei Provinces,is the main part of the North China Plate.Based on the study of outcrop and thin section observation,the distribution pattern of oolitic limestone and its ooid characteristics are presented.Olitic limestones were widely distributed in the area during the Third Series of Cambrian.Generally,the oolitic limestone elevates in strata gradually from east to west,which indicates that the oolitic limestone is diachronous.Huge oolitic... |
