Swope Interval

Isopach map of Swope Limestone exhibits thickening along southern reaches of Kansas shelf bordering the Anadarko and Arkoma Basins. Lithofacies are predominately limestone except for minor clastics deposited along southeastern edge of carbonate shelf.

Swope Oolites

Isopach map of Swope Limestone with porosity greater than 8% Porous carbonate is mainly oolitic lithologies dominated by oomoldic pores. Whereas the large-scale lobes in the map resemble in form modern oolite shoals, these lobes are interpreted to represent composites of temporally distinct shoals similar in scale to shoals deposited in the present-day Joulter’s Cays region.
