Abstract

A new borehole was drilled at the end of the Cartagena Bay. The twofold aim of this operation was to obtain insights into the ancient Roman city seafront, and to establish its cronostratigra-phy and paleoenvironmental evolution. A continuous 30 m long core (E3) was drilled and sampled with high resolution. The se-diments of the lower part (30-11.3 m) with predominant brown colour indicating oxydizing conditions, the brackish-water fauna (Cerastoderma glaucum/Cyprideis torosa) and mud/sand domi-nance, allow to interpret the sedimentary environment as formed in a coastal mud flat linked to an alluvial fan. Consistent AAR da-ting ages reveal that the whole MIS5 record is included. The upper part of the record (11.3-3.0 m), which belongs to MIS 1, is made of black muddy sand and gravel. It appears a high diversity of ma-rine mollusk species mostly in juvenile stage of development. This represents a complex environment: a “cul-d-sac” at the protected end of the bay where plant debris accumulated, being intruded by alluvial inputs. A growing continental influence likely occurred at the top.
