Stratigraphic sequences exposed in the Main (DCM) and East (DCE) Chambers of Denisova Cave. (a) Southeast profile in DCM after excavations in 1984 and (b), Locations of sediment block samples collected in 2014. The concavities on either side of deformed lighter yellow layer 22 (which contains the lowermost artefacts) are infilled with sediments (layers 21–14) that are, in turn, overlain by sub-horizontal layers 13 to 9. (c) Southeast profile in DCE after excavations in 2013 and (d) Locations of sediment block samples collected in 2014. The Pleistocene sequence of hominin occupation spans layers 15 to 9. Layers 17–11 sag towards the centre, above the choke point, and are overlain by sub-horizontal layer 9. Black boxes in panels (b,d) indicate the positions of the micromorphology samples, and the corresponding sample numbers are inset in white; each sample produced 2–3 thin sections, labelled alphabetically from top to bottom. DCM micromorphology samples 4 and 6 were collected from the adjacent east profile.
