A large number of dawsonite-bearing sandstones has been found in Dongying Sag of Bohai Bay basin. The petrological characteristics of these sandstones, such as the framework clastic composition, cements, authigenic minerals and diagenetic paragenesis succession are investigated by polarizing microscope, SEM, and Alizarin Red-S staining etc. The results show that these kinds of dawsonite-bearing sandstone are feldspathic sandstone or debris-feldspar sandstone with mainly fine or fine to medium particle size, poor to mediocre sorting features, poor psephicity and dot-line contact. The cements and authigenic minerals are dominated by overgrowth quartz, dawsonite, calcite, ferrocalcite, ankerite and clay minerals. The amount of dawsonite accounts for 15% by volume. The paragenesis sequence are illite/montmorillonite mixing layer, kaolinite, overgrowth quartz-calcite, ferrocalcite, dawsonite and ankerite.
