On November 1, 1755, the city of Lisbon was completely devastated by combined effect a tremendous earthquake, tsunami waves, and fire. The 1755 earthquake most destructive cataclysm recorded in western Europe since Roman Republic, with an estimated magnitude M w ∼8.5 [ Martins Mendes Victor , 1990] t = 8.5. felt as far away Great Britain Finland. hit many coastal cities along southwest Iberia North Africa, causing heavy destruction Tanger Casablanca.
ABSTRACT Previous palaeomagnetic results from Tertiary volcanic rocks of Sardinia suggest that the island underwent a quick counterclockwise rotation between 20.5 and 19 Ma. In order to test this hypothesis, new study was carried out on sediments with well‐controlled biostratigraphic or radiometric ages younger than suggested age for end rotation. Unrotated directions obtained Upper Ignimbrites (radiometric age: 18.5–19.7 Myr) Aquitanian tuffs collected in Anglona region (N Sardinia) would...
Planktic and benthic foraminifera assemblages from a set of sediment cores, collected on the Adriatic shelf Southern deep basin, provide compelling evidence submillennial-scale environmental changes during last 6000 years. Repeated peaks in Globigerinoides sacculifer represent warm-dry intervals, including `Mediaeval Warm Period', `Roman Age', late `Bronze Age' `Copper Age'. The Last Occurrence (LO) G. (550 years BP) approximates base `Little Ice (LIA). Significant turnovers structure water...
Abstract Holocene cooling events have been reconstructed for the southern Adriatic Sea (central Mediterranean) by means of analyses organic walled dinoflagellate cysts, planktonic foraminifera, oxygen isotopes, calcareous nanoplankton, alkenones and pollen from a sediment core. Two detected, during which sea‐surface temperatures (SSTs) were ca. 2°C lower. Unravelling SST signal into dominant seasonal components suggests maximum winter at around 6.0 ka, whereas 3.0 ka might be result spring...
A multiproxy integrated chronological framework, based on oxygen and carbon stable isotope stratigraphy, biostratigraphy (foraminifera nannoplankton bioevents foraminifer assemblage‐based climate cyclicity), magnetostratigraphy, sapropel 14 C AMS radiometric dates, has been achieved for borehole PRAD1‐2, collected in 185.5 m water depth the central Adriatic. This work was carried out within European Community project Profiles across Mediterranean Sedimentary Systems (PROMESS1). The 71.2 long...
International Continental Scientific Drilling Program (ICDP) drilled a complete succession of the lacustrine sediment sequence deposited during last ~500,000 years in Lake Van, Eastern Anatolia (Turkey). Based on detailed seismic site survey, two sites at water depth up to 360 m were summer 2010, and cores retrieved from sub-lake-floor depths 140 (Northern Basin) 220 (Ahlat Ridge). To obtain sedimentary section, multiple-cored order investigate paleoclimate history sensitive semi-arid region...
Abstract It has long been speculated that biological evolution was influenced by ultraviolet radiation (UVR) reaching the Earth's surface, despite imprecise knowledge of timing both UVR flux and evolutionary events. The past strength dipole field provides a proxy for because its role in maintaining stratospheric ozone. Quaternary events become better constrained fossil finds, improved radiometric dating, use dung fungi as proxies herbivore populations, ages nodes human phylogeny from...
In the last years, paleomagnetism has been increasingly used to provide emplacement ages of loosely dated volcanics. Dating is achieved by comparison paleomagnetic directions with a given reference curve paleosecular variation (PSV) geomagnetic field. Recently, debate developed on achievable precision (the α 95 value) and hence accuracy that “paleomagnetic dating” can yield. At 39 different sites from Etna we paleomagnetically investigated 13 flows (four “test flows” known age, nine flows),...
The uptake ability toward arsenic(V), chromium(VI), and boron(III) ions of ad hoc functionalized magnetic nanostructured devices has been investigated. To this purpose, ligands based on meglumine have synthesized used to coat magnetite nanoparticles (Fe3O4) obtained by the co-precipitation methodology. as-prepared hybrid material was characterized infrared spectroscopy (IR), X-ray diffraction, thermogravimetric analysis, scanning electron microscopy combined with energy-dispersive analysis....
SUMMARY The palaeosecular variation of the geomagnetic field during Holocene has been investigated in marine and lacustrine cores from Italian region. U-channel measurements were carried out on two low-resolution Tyrrhenian Sea (Core ET91-18 ET95-4) Ionian ET99-M11 ET99-M63) representing Late Early–Middle Holocene, respectively. Discrete samples measured Adriatic (PAL94-8 Pal 94-9) maar lake Nemi PNemi 94-1B) containing an expanded section whole Holocene. Temporal variations inclinations...
Abstract Several studies of the rock magnetic properties sediments deposited in suboxicanoxic environments show that bacterial degradation organic matter leads to selective dissolution magnetite with a decrease mineral concentration and an increase grain size. This study upper Quaternary from both marine lacustrine shows many similarities, although diagnetic processes appear be enhanced sediments. When remanence is controlled by fine-grained materials, susceptibility can considered leading...
Many salt-marsh systems worldwide are currently threatened by drowning and lateral erosion that not counteracted sufficient sediment supply. Here we analyze the response of a system to changes in availability show that, contrary what would have been expected, marsh dynamics vertical plane can be insensitive large We integrate sedimentological, geochronological, paleoecological, geophysical, chemical analyses sediments accumulated over past six centuries Southern Venice Lagoon (Italy),...
