“Chert” is the proper term for cryptocrystalline quartzose sedimentary rock. “Flint”does appear to be used (grudgingly) as a valid academic geology term when referring to the chert beds of Flint Ridge, Ohio. Flint Ridge is an ~east-west trending ridge in southeastern Licking County and western Muskingum County in east-central Ohio, USA.Chert occurs as oval to irregular nodules in greensand, limestone, chalk, and dolostone formations as a replacement mineral, where it is formed as a result of some type of diagenesis. Where it occurs in chalk, it is usually called flint. It also occurs in thin beds, when it is a primary deposit (such as with many jaspers and radiolarites). Some limestone contains chert, which is very, very hard silica (like flint). It typically weathers to brown on the surface and occurs in nodules and occasionally replaces fossil shells. It typically weathers to brown on the surface and occurs in nodules and occasionally replaces fossil shells.The single most important and widely used stone in nearly every part of the world was chert, also known as flint. It was widely available, easily worked, and capable of being broken in a controlled manner to create sharp and durable edges.The density may reflect heat-induced changes in flint/chert material as it tends to drop along with the formation of microcracks (Hanckel 1985) or calcination of the material from 400 °C, and especially 500 °C onwards (Weymouth and Williamson 1951; Richter et al. 2011). These changes, however, are already destructive for such lithologies …

Petrographi- cally cherts and flints are structureless forms of chalcedony, both of which are aggregates of cryptocrystalline silica." Chert is generally.

The terms "flint" and "chert" overlap and are sometimes used interchangeably. Both occur as nodules or layers within formations of limestone, dolomite or chalk. Flint is generally considered a finer-grained, more homogenous, and somewhat harder type of chert. It also exhibits a better-defined conchoidal fracture that lends itself to ...

This is the common variety of chert, a term which also includes other, more spectacular varieties such as flint (by definition, the variety found in chalk), agate and jasper. Chert is much harder than limestone or dolomite, and tends to break with a conchoidal fracture , leaving sharp edges - hence its use for making tools and weapons.From $20.00. Show options.

Both - chert and flint - can have the same origin (usually remobilization from sponge spikules of silica gel), both are a rock. Usually chert has less silica (in %) even in central part than flint.The neat thing about looking for flint on a modern gravel bar is that all of the varieties of flint within the upstream drainage basin are present in the downstream gravel bars. In addition, the river does a good job of breaking up the fractured materials, leaving intact only the strongest and most durable cobbles of flint and chert. Chert Nodules Chert nodules are not concretions, but in Devonian rocks of central New York they can frequently have bizarre shapes that are similar to those of concretions. Chert is micro- or cryptocrystalline silica (SiO₂; also known as chalcedony or flint) which forms under particular chemical conditions inside soft sediments.The source of the silica is mainly biogenic with the opaline silica of diatoms, radiolarian and siliceous sponges being redistributed. Chert formed in this way occurs as nodules within a rock, such as the dark flint nodules that are common within the Cretaceous Chalk, and as nodules and irregular layers within other limestones and mudstones.

It is a form of microcrystalline quartz that is typically called "chert" by geologists. Flint often forms as nodules in sedimentary rocks such as chalk and marine limestones. The nodules can be dispersed randomly throughout the rock unit but are often concentrated in distinct layers.The best rocks for flint-knapping are chert, flint, chalcedony, quartzite, jasper, and obsidian. Chert and flint are silica-rich rocks found throughout the Midwest in limestone and dolomite deposits.
