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.
