Bronte and Fulshear soils have sola more than 40 inches thick. Katemcy soils have a lithic content of schist at a depth of 20 to 40 inches. Bexar and Scullin soils have a mollic epipedon. Bonti soils are more acid in the argillic horizon and are 20 to 40 inches thick over sandstone bedrock. Lindale soils have secondary carbonates with 28 inches of the soil surface and lack a lithic contact of limestone.
Rowden soils have a mollic epipedon.
The regolith is loamy and clayey and is over thick beds of strongly cemented or indurated limestone. The underlying limestone is generally of lower Cretaceous age but some areas are over Pennsylvanian or Permian limestone. The climate in the area of occurrence is dry subhumid with a mean annual precipitation range of 24 to 34 inches. Bexar soils are on positions similar to Lindy soils. Hensley soils have sola less than 20 inches thick.
