different between chert vs quartz

English

Etymology

Unknown.

Noun

chert (countable and uncountable, plural cherts)

1. (geology, uncountable) Massive, usually dull-colored and opaque, quartzite, hornstone, impure chalcedony, or other flint-like mineral.

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.
