This terrace gravel contains exotic quartzite derived from the west.GRAVEL COMPOSITION High-terrace and hilltop gravel deposits are composed almost entirely of crudely bedded chert derived from lower Permian bedrock of the Flint Hills. Milky quartz and siliceous fossils, also derived from the same bedrock sources as chert, are another component of these gravels. Chert is a sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO 2). It occurs as nodules, concretionary masses, and as layered deposits. Chert breaks with a conchoidal fracture, often producing very sharp edges.

The 2Bt horizons contain 5 to 30 percent chert gravel and 0 to 25 percent fragments larger than 3 inches. About 20 percent are less than 1/4 inch in size. Some pedons are stony on the surface. The particle size control section averages from 60 to 85 percent clay. then the gravel will be classified as a clayey gravel (GC). Once the determination has been made whether the fines are silt or clay, the classification can be further refined by estimating the percentage of sand size particles present in the sample.
