Well preserved radial calcitic ooid grains that accumulated on higher energy shoals. Initial rim cements may be after marine rims. Later these rimmed cements have undergone alteration to calcite with freshwater driven diagenesis. The final void fill cementation was by low magnesian calcite spar. The carbonate of the cement was probably derived from earlier aragonitic material. Pressure solution at grain contacts; note how sometimes the radial fabric penetrates grain boundaries at these contacts.
