Abstract

Based on pioneer studies of lithostratigraphy, biostratigraphy and chronostratigraphy, authors analysed sequence stratigraphy and sedimentary microfacies of the Lower Middle Ordovician. Two sorts of sequence surfaces are discerned exposing sequence unconformities and drowing sequence unconformities. Three kinds of parasequence moulds are summaried as the tidal flat parasequences, the shoal parasequences and the shelf parasequences. Two main types of system tracts are formed by stacking patterns of parasequences transgressive systems tract and highstand systems tract. Based on these studies, Lower Middle Ordovician strata can be divided into 7 three grade sequences. Among these, The Sq1 2 three grade sequences are comparable with Penglaiba formation, the Sq3 6 three grade sequences are comparable with Yingshan formation and the Sq7 three grade sequence are comparable with Dwangou formation. The Sq1 2 three grade sequences are composed of penecontemporeous dolostones and carbonates tidal flat cycles, and the Sq3 6 three grade sequences are composed of tidal flat cycles and shoal cycles and the Sq7three grade sequences are composed of shelf facies carbonates.
