Mudbrick architecture, destruction layers and settlement sediments as a record of an Iron Age urban context in the southern Levant.
Key findings
What the study foundElevated potassium proved a useful proxy for mudbrick, helping distinguish intact and degraded earthen architecture.
Why it mattersParts of a settlement plan can be reconstructed even where erosion and decay have removed clear wall boundaries.
What the study foundHigh P and K, low Ca, luminescence signals and the near absence of lipids together support a thermally altered destruction horizon.
Why it mattersSeveral independent measurements can reveal an event that is no longer macroscopically obvious in the field.
What the study foundpOSL supports the stratigraphic integrity of the profile, while spatial variability demonstrates differential preservation of layers.
Why it mattersResearch can distinguish a real absence of past activity from areas where evidence was later removed or transformed.
Tel Burna is located in the Shephelah of Israel. Area G includes the gate complex and fortification zone, where mudbrick, floors and destruction deposits form a complex stratigraphic record.
The site is a model case for contexts where visible stratigraphy is unclear, but the archaeological record remains preserved in chemical and physical signals.
Potassium helps identify mudbrick architecture and collapsed earthen material, while high calcium reflects chalk and carbonate-rich floors.
pOSL, lipids and DNA help evaluate stratigraphic integrity, erosion, preservation and organic degradation with depth.
Phosphorus indicates occupation horizons, waste, burning, activity surfaces and destruction sediments.
Calcium marks chalk and carbonate-rich floors, especially in Strata II and III.
Potassium is the main proxy for mudbrick and collapsed earthen architecture.
Luminescence and biomolecular data help assess burial, mixing, preservation and degradation of organic residues.
In Area G, erosion and post-depositional processes obscure parts of the stratigraphic sequence. Some archaeological boundaries are difficult to define macroscopically.
The question is whether the buried sequence can still be reconstructed from independent material signals.
The study combines elemental chemistry, luminescence and biomolecular data to distinguish floors, mudbrick, destruction horizons and post-depositional change.
Large-scale sampling from an Iron Age urban context in the southern Levant
The study integrates pXRF, pOSL, organic residue analysis and DNA to reconstruct Area G, where visible layers are partly ambiguous due to erosion and post-depositional processes.
Tel Burna shows that settlement layers do not always need to be visually distinct to remain archaeologically readable. Their signal can be preserved in soil chemistry, luminescence and biomolecular traces.
The site therefore serves as a reference case for studying mudbrick architecture, destruction deposits and hidden stratigraphy in tell environments.
