| Lithology description: "[M[ainly biomicrite and microspar limestone, interbedded with greenish-gray calcareous shale along the axis of the aulacogen. The type section in the southwestern Arbuckles is 71 m thick, with much greenish-gray calcareous shale, and probably represents an area close to the Pooleville depocenter. In most of the Arbuckle Mountains, the upper 5 m of Pooleville is a massive burrowed micrite or calcilutite of the intertidal facies. In the Criner Hills, the Pooleville is about 40 m thick and is mainly a thin-bedded to medium-bedded mudstone or microspar limestone, deposited along the southern margin of the aulacogen. In the northeastern adn northern Arbuckles, the Pooleville is less than 21 m thick, with some birdseye micrite in the upper part." Lithology from R, O. Fay and A. A. Graffman. 1982.
