What is a chert rock

Chert is made up of microscopic silica (silicon dioxide) crystals and is usually formed from the accumulation of the shells of microscopic sea creatures. Jasper, on the other hand, is composed of compacted and cemented sedimentary rock that contains impurities such as iron or other minerals, giving it a wide range of colors and patterns.

Chert is widespread, but not widely known by the public as a distinct rock type. Chert has four diagnostic features: the waxy luster, a conchoidal (shell-shaped) fracture of the silica mineral chalcedony that composes it, a hardness of seven on the Mohs scale, and a smooth (non-clastic) sedimentary texture.

Sedimentary rock - Iron-Rich, Clastic, Chemical: Almost all sedimentary rocks are iron-bearing in the sense that mudrocks, sandstones, and carbonates typically have an iron content of several percent. Nevertheless, sedimentary rocks in which the proportion of iron exceeds 15 percent are separately categorized as iron-rich. Two major types of iron-rich sedimentary rocks are recognized: (1) iron ...Chert: Clastic Sedimentary Rocks. How Clastic Sedimentary Rocks are Formed: Pre‑existing rock undergoes chemical and mechanical weathering by roots, acid rainwater, gravity, wind, and water. The broken particles are carried through water or air until they settle out in a lower area when the current wasn’t fast enough to carry the particles.Chert, on the other hand, is considered a hard or fine-grained sedimentary rock that is made of microcrystalline quartz which is a mineral form of what is known as silicon dioxide. It is usually found in layer deposits or nodules as well as consecration masses. FLINT - A cryptocrystalline rock that falls under the chert group.

This type of sedimentary rock can form in parts of the deep sea where the tiny shells of siliceous organisms are concentrated, or elsewhere where underground fluids replace sediments with silica. Chert is a hard, aphanitic, non-clastic rock composed entirely of microcrystalline quartz.
