“…Anzidei et al (2011) have evaluated at different archaeological sites of Punic-Roman age the change in sea level since about 2000 years ago along the coasts of Tunisia and Libya. These results, which are consistent with those of Oueslati (1995) and Slim et al (2004), show significant variability in the rise in the sea level at different sites. Their estimation of the sea level rise over the last 2000 years is between 0.2 and 0.5 m on these coasts.…”

“…This sedimentary thickness would thus have buried the paleochannels responsible for the infilling of this ancient arm of the sea and of the northern compartment. This appears to be confirmed by the fact that the sea level in the Punic-Roman period was lower by several decimeters than the present LMSL (Figure 3; Oueslati, 1995;Slim et al, 2004;Anzidei et al, 2011). This appears to be confirmed by the fact that the sea level in the Punic-Roman period was lower by several decimeters than the present LMSL (Figure 3; Oueslati, 1995;Slim et al, 2004;Anzidei et al, 2011).…”

International audienceAlthough the ancient site of Utica has been studied since the 19th century, the location of its harbors remains unresolved as they were buried under sediments as the Mejerda delta prograded and left Utica 10 km inland. Using relief data and a coring survey with sedimentological analysis, we identify the dynamics of the delta's progradation, which produced a double system of alluvial fans. These show that the ancient bay of Utica silted up faster and earlier than was thought, probably before the end of the Punic period. Combined with the radiocarbon dates from coring, this suggests that the harbor lay on the northwestern side of the Utica promontory, communicating with the sea by a marine corridor west of the northern compartment of the delta. As the infilling of the ancient bay progressed, this corridor narrowed until it disappeared completely in the early 5th/mid-6th century A.D., when a peat bog developed on the northern side of the promontory, sealing the fate of Utica as a port. This relative environmental stability ended in the 9th–10th century A.D. when about 4 m of sediment, probably of fluvial origin, covered the peat bog, leaving the site more than 4.5 m above the local sea level.

“…Progradation of Tunisia's eastern coast occurred at a rapid rate, creating large alluvial coastal plains at the mouths of rivers during Punic and Roman occupation (Oueslati, 1995). Many Roman structures are found beneath sediments, where alluviation has pushed the shoreline many kilometres seaward.…”

“…There has been a continuous rise in sea level over the past 2000 years, which, together with the progressive subsidence of the Sahel, has caused a retreat of the Tunisian coastline submerging many Roman buildings (Oueslati, 1995). The intrusion of sea water has caused the development of salt pans (chotts) and supratidal saline lakes (sebkhas) throughout the Sahel, which are banked by crescent-shaped dunes (lunettes), composed of very fine, carbonate aeolian sediment (Martin, 1967).…”

The source of raw materials for Roman pottery from Leptiminus, Tunisia

et al. 2002

Leptiminus, a Roman port city on the west coast of Tunisia, North Africa, exported olive oil and a garum fish paste to Rome. Excavations have uncovered many facilities including kilns and a potter's workshop, indicating an extensive ceramic industry. The vessels, manufactured at Leptiminus, included African red‐slip fineware, coarseware, and amphorae. A petrographic study of pottery sherds showed them to contain very similar temper, rounded aeolian sand grains and limestone, but varying in proportions to produce different textures. An investigation of the source of raw materials for the pottery found three distinct types of clay within a 50 km radius of Leptiminus: grey Miocene, brown Pliocene, and green Late Pliocene clay. Statistical analysis of trace element compositions, using induced neutron activation, of clays and sherds showed that the Pliocene brown clay was used to create all types of pottery. The specific clay horizon, used in Roman times, has apparently been removed by quarrying. However, a lateral continuation of this bed was found 7 m beneath the Leptiminus site 290. © 2002 Wiley Periodicals, Inc.
