Usually found as rounded nodules in limestone and dolomite or, less often, an extensive layered deposit, chert is harder and more resistant to erosion than limestone.Feb 2, 1998 · Chert, also known as flint, is one of the most abundant rocks in Missouri, and is composed of one of the most common minerals on earth. In fact, in much of Missouri you could say that chert is "common as dirt." Chert is a hard, fine-grained rock made up mostly of the mineral silica (SiO2). Silica itself contains the elements silicon and oxygen ... Limestone mining and utilization in Missouri began in the mid 1800s. The amount mined prior to 1920 is not known for certain.
