chert
[ tสษหrt ]
informal term
The term 'chert' refers to a type of sedimentary rock that is composed mainly of silicon dioxide. It can appear in various colors, often gray, black, or brown, and has a glassy texture. Chert is commonly found in marine deposits and can form through the accumulation of microscopic silica organisms over millions of years. In archaeology, chert is significant as it has been used by humans for tool-making throughout history. The properties of chert make it a valuable material for various industrial applications, including the production of glass.
Synonyms
flint, hornstone, silica rock.
Examples of usage
- The ancient tools were made of chert.
- Geologists often study chert formations.
- Chert can be used to create sharp edges.
- This chert bed has fossils inside.

Etymology
The term 'chert' is derived from the Old French word 'cherte' and possibly linked to the German word 'Kies', which means gravel. Its use dates back to the 17th century, where it began to be used in geological contexts to categorize certain types of siliceous rocks. Historically, chert has played a significant role in human development; early humans utilized it to make sharp tools and weapons, as its hardness allowed for easy flaking. The study of chert has expanded over the years from merely geological descriptions to encompassing its archaeological significance, particularly in understanding early human technology and prehistoric cultures. Its formations are often of particular interest to geologists because they can indicate past environmental conditions.
