Chert. Chert is a sedimentary rock consisting almost entirely of silica (SiO 2 ), and can form in a variety of ways. Biochemical chert is formed when the siliceous skeletons of marine plankton are dissolved during diagenesis, with silica being precipitated from the resulting solution. Replacement chert forms when other material is replaced by ...These released elements form authigenic quartz, chert, calcite, dolomite, ankerite, hematite and albite, all trace to minor (except quartz) minerals found in shales and other mudrocks. Organic matter. Very important component carbonaceous material in the shale rocks.Chert (/ ˈ tʃ ɜːr t /) is a hard, fine-grained sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO 2). Chert is characteristically of biological origin, but may also occur inorganically as a chemical precipitate or a diagenetic replacement, as in petrified wood .

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 …The stone is made up of spherical stones of red jasper, black chert, and white quartzite that have been “cemented together” by quartz. Pudding stones may be found on Drummond Island and along Michigan’s eastern coast. ... with trace quantities of mica, amphiboles, and other minerals.

Complex magnetic mineral mixtures in red chert have long been a barrier for making detailed paleomagnetic and environmental magnetic interpretations. Using a combination of IRM acquisition curve unmixing, FORC-PCA unmixing and M rh PCA, we describe an improved approach for discriminating hematite and magnetite in red chert.
