Gray chert in tan limestone in Chase County. Commonly called flint, chert is a fine-grained, noncrystalline sedimentary rock made up of silicon dioxide (SiO 2 ). (The mineral quartz has the same chemical formula.) Chert layers are commonly found in eastern Kansas, occurring as irregular beds or rounded nodules within limestone formations. Slopes range from 0 to 2 percent. They formed in loamy alluvium washed from soils formed in material weathered from cherty limestone, or interbedded cherty limestone, shale, and sandstone . Near the type location the average annual temperature is about 60.5 degrees F., and the average annual precipitation is about 56.9 inchesThe cherty limestone has also yielded a fairly good number of radiolaria in addition to planktonic foraminifera.
