In geology and archaeology, dark earth is a substratum, up to 1 metre (3 ft 3 in) thick, that indicates settlement over long periods of time. The material is high in organic matter, including charcoal, which gives it its characteristic dark colour; it may also contain fragments of pottery, tile, animal bone and other artefacts.
