chert
English
Noun
(geology, uncountable) Massive, usually dull-colored and opaque, quartzite, hornstone, impure chalcedony, or other flint-like mineral.
(countable) A flint-like tool made from chert.
Usage notes
Generally, in mineralogy and geology, a chert does not have a conchoidal fracture. In North American archeology the term chert occasionally is still used for various siliceous minerals (including flint) that have a conchoidal fracture; this leads to confusion between the terms flint and chert in some archeology texts.
