[edit] Material Provenance

Geoarchaeology has a long history in provenacing studies (reference). Mineralogical and geochemical study of archaeological artefacts and deposits can help to reveal their source, and hence provide information on resource management and trade in past societies.

Artefacts: Many mineraological and metallurgical resources have regionally unique chemical or isotopic signatures that enable them to be traced back to their area of origin. Many artefacts are small and may be traded over large distances, identifying the original source area in these instances can provide information about regional and even global trade links. In other cases materials may be sourced and used locally this too can provide archaeological insight into local land resource management.
Construction materials: Because construction materials tend to be bulky and heavy they are often (though not always) sourced locally. Understanding where, however, can provide valuable insights into the management of local resources, particularly where such sources are rare or otherwise under pressure (references).
Sediments and soil: Identifying source areas for wind (aeolian) or water-lain (alluvial) sediments can provide information on regional patterns of erosion. In some cases this erosion may linked to past human activity, such as agriculture, hence studies to source alluvial deposits have tried to reconstruct past spatial and temporal patterns of land use in river catchment areas.
