Abstract The ooids have the trends to be much smaller in individual and core diameters, much rounder in shape and higher sparry cementation among ooids from bottom to top in the oolitic limestones of the Cambrian Series 3 in Dengfeng area, western Henan Province. These characteristics display the evolution from unstable oolitic limestones of deep continental shelf to much shallower high construction bank shoals. Three stages of oolitic limestones can be distinguished as follow.(1)The oolitic limestones occurred in deep platform slope are dominated by radial and tangential-radial ooids. The ooids have the big size and the higher diversity in their shapes. The filling arounding them is mostly consisted of mud.(2)The oolitic limestones occurred in oolitic shoal front of gentle platform slope contain tangential-radial and tangential ooids and have the variable oolitic content and size. The porosity among ooids occupied by microsparry and sparry calcites.(3)The high construction oolitic shoals of the platform margins are characterized by dolomitic tangential and micritic ooids and have the much higher oolitic content and much smaller size. The porosity among ooids occupied by sparry calcite. The relative water depth become much shallower, the construction environment of oolitic shoals become much perfect and stable, the thickness and distribution of oolitic shoals gradually expand the scales from Member A to Member
