Chert is a fine-grained and hard sedimentary rock that usually has a biological origin. Chert can also exist inorganically as a chemical precipitate or diagenetic replacement in petrified wood. Chert can be of various colors due to trace elements in the rock.19 May 2020 ...

Chert is a fine-grained, sedimentary rock consisting largely of silica but also containing other minerals. An attractive banded variety, called ribbon stone, is found in Western Australia and the Northern Territory.

This is also the way the flint has been crafted into arrow heads, axes, and knives in the stone age or by American Indians in historic times. Flint, Jasper, Radiolarite, Mozarkite, and Onyx are some the most common varieties of chert. 9. Dolostone. Dolostone is a name given to a type of sedimentary rock which is primarily composed of dolomite, a carbonate mineral.

The Formation of Chert. Chert will form in carbonate type rocks, whish is a type of sedimentary rock, as nodules or larger masses. As the sediment that can make up greensand, chalk, dolomite, and limestone get buried deep within the earth over time, these pockets of chert will form as well in the immense pressure and heat.13 Nov 2013 ...

What is Chert? 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.

It commonly occurs in the form of nodules, layered deposits and concretionary masses. Chert rock is composed of remains of siliceous ooze, the sediment which covers the major portion of the deep ocean floor.

Such a mass may consist of sediments and particles (sand, gravel, clay, or volcanic ash, for example) as well as solid material (limestone, sandstone, granite, etc.). A rock generally is composed of one or more minerals. Rocks occur in three main types, each of which was formed in a different way.
