Postexcavation

Postexcavation is the phase of archaeological project work that follows field excavation. It encompasses the processing, analysis, interpretation, and reporting of materials recovered during excavation, as well as the preservation and management of data and collections for future study.

Core activities include cleaning, cataloging, and conserving artifacts; recording provenience and contextual information; and organizing objects and records in accessible repositories. Laboratory analyses may cover typology, dating (absolute and relative methods such as radiocarbon, dendrochronology, and luminescence), and analysis of ecofacts (pollen, seeds, charcoal) and faunal remains. Feature and soil analyses help reconstruct site formation processes and occupation history.

Data management is central, with database entry, metadata standards, photography, and digitization of records. Spatial analysis and reconstruction using GIS, CAD, and 3D modeling support interpretation. Archived site reports, diaries, photographs, and casts are prepared for long-term storage.

Interpretation synthesizes results into a site chronology and regional context, leading to publication in reports, journals, and online databases. Public dissemination and outreach may be included, along with the preparation of summaries for stakeholders and descendant communities.

Ethical and governance considerations govern postexcavation work, including data sharing, open access when possible, repatriation of materials where required, and adherence to legal and professional guidelines.
