Abstract. It is proposed that many nodular cherts in limestone have formed in the ground water of mixed meteoric-marine coastal systems where dissolution of biogenic opal and mixing of marine and fresh waters can produce waters highly supersaturated with respect to quartz and undersaturated with respect to calcite and aragonite. 11) A cherty limestone would contain which major constituents?

Chert Limestone AAPG geologic province: AppalachCite as: Deep Sea Drilling Project (1989): Archive of Core and S 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. 1974 Characteristics, Interpretations, and Uses of Pennsylvania Soils Developed from Cherty Limestone Material. Ciolkosz, et al. Penn State Agr. Expt. Sta. Prog. Rept. 341. 1974 Characteristics, Interpretations, and Uses of Pennsylvania Soils Developed from Colluvial Materials. Flint is a compact microcrystalline quartz. · Nodules of chert in limestone are easily recognizable because of their characteristic shape, hardness (around 7, harder than metal on scratch) and conchoidal fracture. The color of chert nodules is highly variable depending on the trace elements and minerals present. Chert is more resistant to erosion than limestone. 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).
