Formation Process Analysis

Formation process analysis is the framework for identifying the cultural and natural processes that transform materials from their living, systemic context into the archaeological record we excavate. Developed by Michael Schiffer within behavioral archaeology and codified in his 1987 Formation Processes of the Archaeological Record, it insists that the archaeological record is not a fossilized snapshot of past life but the cumulative product of how things were discarded, lost, reused, and disturbed (cultural or C-transforms) and how they then decayed, moved, and mixed in the ground (natural or N-transforms). Because every deposit has been filtered and rearranged by these processes, sound inference about past behavior requires first reconstructing the formation history of the record and correcting for it. Formation process analysis is therefore foundational to interpretation, linking excavation, geoarchaeology, and taphonomy.
