Proterozoic Paleozoic sequence stratigraphy of the Jianping Kazuo district, western Liaoning province

摘要: 通过１∶５万区域地质调查工作，对建平—喀左地区元古宙—古生代地层做了岩石地层、生物地层、不整合界线地层和层序地层的多重划分与对比。进行了基本层序、沉积相和沉积环境的调查研究，将元古宙—古生代地层划分为１０个层序，归并为２个超层序，初步建立了岩石地层和年代地层格架。
Abstract: Through 1:50 000 regional geological mapping in the Jianping Kazuo district, western Liaoning province, an attempt has been made to perform multiple stratigraphic division and correlation of the Proterozoic Paleozoic strata, i.e. the lithostratigraphic, chronostratigraphic, biostratigraphic, unconformity bounded stratigraphic and sequence stratigraphic division and correlation. Their essential sequences and sedimentary facies and environments have been investigated and studied in detail. The Proterozoic and Paleozoic strata of the region may be divided into ten sequences and incorporated into two supersequences, namely the Jianping supersequence （Proterozoic） and the Kazuo supersequence （Paleozoic）. Based upon these studies, the lithostratigraphic framework and chronostratigraphic framework have been established.
