An archaeological industry, normally just "industry", is the name given in the study of prehistory to a consistent range of assemblages connected with a single product, such as the Langdale axe industry. Where the assemblages contain evidence of a variety of items and behaviours, the more correct term is "archaeological culture", although both terms are often used to describe the same assemblage by different sources. They may also be referred to as "lithic industries" where the products are stone tools or weapons.
