The Geomorphologycal map of the continental shelf northeaster sector Sardinian coast has allowed recognition several seafloor features. These have been related to geology and climate history area from Last Glacial Maximum (LGM) early Holocene. During LGM sea level was about 130 below present cuspate deltas fed by rivers crossing formed. post rise caused submersion exposed changed dominant sedimentary processes. not continuous but punctuated stillstands during which suites beach ridges...
Abstract A multi‐proxy record is presented for approximately the last 4500 cal a BP from Lake Shkodra, Albania/Montenegro. Lithological analyses, C/N ratio and δ 13 C of organic inorganic carbon component suggest that matter bulk carbonate are predominantly authigenic. The 18 O indicates presence two prominent wet periods: one at ca. 4300 2500–2000 BP. latter phase also found in southern Spain Central Italy, represents event western central Mediterranean. In 2000 years, four relatively...
Loess deposits in southern Britain contain a record of dust, climate and landscape dynamics over the last glacial, yet their age accumulation rate remain poorly known. Furthermore, environmental controls on loess-soil stratigraphy shown thickest southeast England are still debated. Here we apply first high sampling resolution quartz optically stimulated luminescence study dust loess formation at Pegwell Bay site east Kent. We couple this to mineral magnetic, particle size geochemical...
Transgressive dunes develop frequently along strandplain coastlines; however, they may also form rocky coasts dominated by cliffs and embayments. Two lithified transgressive dune systems developed the cliffed Alghero coast (NW Sardinia, Italy) have been investigated. One aeolian system forms a cliff-front anchored accumulation; other is valley-head sand-ramp system. Optically stimulated luminescence ages indicate that both formed around 75 ka. This period, which corresponds to beginning of...
Mapping of coralligenous banks was carried out along the continental shelf northern and western margin Sardinia Island (Italy, Mediterranean Sea) in context European Marine Strategy Framework Directive (MSFD, 2008/56/EC). Coralligenous are bioconstructions produced by calcareous coralline algae. Seafloor mapping through multibeam echosounder surveys video transects, using a Remote Operating Vehicles (ROV), areas not formerly explored. A high-resolution digital model seabed (DTM) obtained...
Abstract Sediments at Pias (Galicia) provide evidence of Upper Pleistocene glacial activities a valley junction in the north-western mountains Spain. The sedimentary sequence consists lower, predominately fine-grained lacustrine deposits with few lonestones, overlain by poorly sorted, sandy gravels interstratified massive diamicton deposited during mid-Weichselian times (MIS 3) (marine isotope stage 3). sediments were temporarily dammed confluent glacier. presence active ice is suggested...
We performed a morpho-stratigraphic study of the Tirso River incised valley (Sardinia Island, western Mediterranean Sea), an erosional feature crossing Sinis fault, major normal fault bordering Campidano basin between Gulf Oristano and Sardinia shelf. High-resolution seismic reflection profiles multibeam echosounder data, integrated by age-constrained stratigraphic logs derived from 9 sediment cores enabled us to reconstruct evolution during Holocene. found that is result single event...
Coralligenous reefs are the main biogenic constructions of Mediterranean Sea and they considered indicators ecological quality coastal systems "seafloor integrity" by Marine Strategy Framework Directive. The two coralligenous morphologies cliffs platforms, former developing in shallow waters (about 20–50 m) on vertical/subvertical rocky substrate latter built over horizontal substrates below 50 m depth also detritic bottoms. present study aims at assessing whether patterns spatial...
Abstract A multi‐disciplinary approach was followed to investigate two thick palaeosol strata that alternate with wind‐blown dominated deposits developed along the Alghero coast (North‐west Sardinia, Italy). Optically stimulated luminescence ages reveal both palaeosols were during cooler drier periods: first one at around 70 ka Marine Isotope Stage 4 and latter 50 (Marine 3). In contrast, pedological features indicate underwent heavy weathering processes under warm humid sub‐humid...
Abstract The Quaternary deposits of tectonically stable areas are a powerful tool to investigate high‐frequency climate variations (<10 ka) and distinguish allogenic autogenic factors controlling deposition. Therefore, an Upper Pleistocene–Holocene coastal apron‐fan system in north–western Sardinia (Porto Palmas, Italy) was studied the relations between changes, sea‐level fluctuations sediment source‐supply that controlled its development. sedimentary sequence records strong influence...
The islet of Scoglio d'Affrica (Tuscany Archipelago, northern Tyrrhenian Sea) is an emerging segment the Elba-Pianosa Ridge. This ridge a major tectonic-structural high formed by Eocene-Early Miocene clastic succession which separates Tuscany shelf from Corsica Basin. distinctive structural setting region result crustal fragmentation during extensional tectonic regime Northern Sea. Along Elba Pianosa Ridge, complex interplay between magmatism, active submarine gas emissions and mud volcanism...
The Sydney Basin covers a large offshore area south of Newfoundland, with well-exposed outcrop belt on Cape Breton Island. geological history the poorly known is interpreted using an industry seismic grid and Lithoprobe line 86-5, tied to outcrops two wells. mid-Devonian Upper Carboniferous - Permian basin fill 6-7 km thick represents three extensional phases intervening succeeding compressive phases. McAdams Lake Formation was deposited in local half-graben during early post-Acadian...
Abstract Precise dating of the activity Late Pleistocene to Holocene neo‐tectonic structures is crucial quantify rate deformation in low‐seismicity regions. Sardinia a relatively stable continental fragment set middle tectonically active Western Mediterranean belt. This paper provides evidences significant uplift northwest that support an ongoing tectonic since Marine Isotopic Stage 7 (MIS 7; ca. 220 ka). In particular, it documents for first time tectonics based on luminescence travertine...
