A flint-like tool made from chert

A very fine grained rock formed in ancient ocean sediments It often has a semi_glassy finish and is usually white, pinkish, brown, gray, or blue_gray in color It can be shaped into arrowheads by chipping It has often been called flint, but true flint is found in chalk deposits and is a distinctive blackish color

variety of silica containing microcrystalline quartz

a sedimentary rock made of microcrystalline quartz, it forms from the skeletons of microscopic marine organisms

a flint-like stone formed throught the replacement of limestone by silica contained in mineral-rich ground water

A fine-grained crystalline aggregate of silica, with excellent fracturing properties, producing good cutting edges on stone tools Similar to flint, agate, chalcedony and jasper

A hard sedimentary rock made of quartz (usually called flint)

A hard variety of sedimentary rock, similar to flint It breaks in a predictable fashion which made it highly desirable for prehistoric toolmakers

Hard sedimentary rock composed of microcrystalline quartz, usually light in color, common in the Springfield Plateau in gravel deposits Resistance to chemical decay enables it to survive rough treatment from streams and other erosive forces

An impure, massive, flintlike quartz or hornstone, of a dull color

A type of fine-grained, silica-rich rock often found in limestone Native Americans shaped chert by carefully striking it with stone or bone hammers

{i} type of rock

A mainly opaque, fairly granular, silicate rock with a dull shiny luster and a great range of colours, used as raw material for the manufacture of chipped stone artifacts Varieties include jasper and flint

A compact cryptocrystalline or microcrystalline variety of quartz originating from a sedimentary context

A fine-grained silica-rich rock occurring within sedimentary and volcanic rocks

Cryptocrystalline silica Composed of extremely fine (submicroscopic) silica crystals

A rock resembling flint and consisting essentially of cryptocrystalline quartz or amorphous silica

A flintlike rock composed of chalcedony with variable amounts of clay and other impurities; commonly selected as a raw material for flaked-stone tools (Moratto 1984: 587)

a fine grained sedimentary rock that is white, pinkish, brown, gray or blue-gray in color It is often shaped into stone artifacts by chipping
