So far, the Pleistocene Series is not subdivided into formal units (i. The Holocene is a Geological epoch which began approximately 10000 years ago (about 8000 BC In the 8th millennium BC, Agriculture becomes widely practiced in the Fertile Crescent and Anatolia. In Paleoclimatology of the Holocene, the Boreal was the first of the Blytt-Sernander sequence of North European climatic phases that were originally The Atlantic in palaeoclimatology was the warmest and most moist Blytt-Sernander period Pollen zone and chronozone of Holocene north Europe. The Pleistocene ('plaɪstəsin is the epoch from 18 million to 10000 years BP covering the world's recent period e. , Stages). Several solutions were proposed, and dedicated working groups are presently pursuing an agreed solution. Since the base of the Pleistocene is already pinned down at Vrica (Calabria, Southern Italy), only Middle and Upper Pleistocene are to be formally defined yet. Calabria ( Latin: Brutium) is a region in southern Italy, south of Naples, located at the "toe" of The Late Pleistocene (also known as Upper Pleistocene or the Tarantian) is a stage of the Pleistocene Epoch. Concerning the Middle Pleistocene, an agreement has been achieved by proposing the so-called “Ionian” Stage. Upon international agreement, the base of the Ionian Stage should be located close to the bottom of the Brunhes Chron, while its top would coincide with the base of the Upper Pleistocene, which in turn spans from the beginning of the last interglacial (i. The Brunhes-Matuyama Reversal was a geologic event approximately 780000 years ago when the Earth's magnetic field last underwent reversal. The Late Pleistocene (also known as Upper Pleistocene or the Tarantian) is a stage of the Pleistocene Epoch. e. Marine isotopic stage 5) to the base of the Holocene (~10. Marine isotopic stage s (MIS are alternating warm and cool periods in the Earth's paleoclimate, deduced from oxygen isotope data reflecting temperature curves derived The Holocene is a Geological epoch which began approximately 10000 years ago (about 8000 BC 5 Ka). Especially suitable sections for defining the base of the Ionian stage are located in Southern Italy. In fact, during Lower and Middle Pleistocene the Adriatic-Ionian margin was characterized by high sedimentation rates, in response to intense differential tectonic subsidence and massive sedimentary yield. The Ionian Sea is an arm of the Mediterranean Sea, south of the Adriatic Sea. Specifically, candidate sections are the “Montalbano Jonico” Section (Bradanic Trough, Basilicata Region) and the “Valle di Manche Nord” Section (San Mauro Marchesato, Crotone Basin, Calabria Region). Montalbano Jonico is a town and Comune in the Province of Matera, in the Southern Italian region of Basilicata. Basilicata is a region in the south of Italy, bordering on Campania to the west Apulia ( Puglia) to the east Calabria to San Mauro Marchesato is a Comune and Town with a population of 2002 people in the Province of Crotone, in Calabria, Italy. Calabria ( Latin: Brutium) is a region in southern Italy, south of Naples, located at the "toe" of In the former, a spectacular succession of marls laid in the Apennine foredeep is exposed which, however, are unfortunately unsuitable for magnetostratigraphic analyses. Stratigraphy, a branch of Geology, studies rock layers and layering ( stratification) The latter, which is represented by a shallowing-upward succession that developed in an outer-shelf environment, has the bonus of a sharp biomagnetostratigraphic record, which provides tighter age control. Besides these exposures, a number of ODP cores drilled either in the Ionian Sea (Site 964) and in the Sicily Channel-Capo Rossello area (Site 963) are available, which correlate well with the on-land sections mentioned above based on a significant number of criteria (magnetostratigraphy, biostratigraphy, sapropel stratigraphy, stable isotopes, Tephrochronology). The Ocean Drilling Program ( ODP) was an international cooperative effort to explore and study the composition and structure of the earth's ocean basins Biostratigraphy is the branch of Stratigraphy which focuses on correlating and assigning relative ages of rock strata by using the Fossil assemblages contained Sapropel (a contraction of ancient Greek words sapros and pelos, meaning Putrefaction and mud respectively is a term used in Marine geology Tephrochronology is a geochronological technique that utilises discrete layers of Tephra &mdashvolcanic ash from a single eruption&mdashto create a chronological The interval corresponding to the Ionian Stage is especially well represented in Site 963, where no turbidites and/or hiatuses are recognized. Presently, the Montalbano Ionico section is possibly the main candidate for defining the Lower - Middle Pleistocene boundary, once a reliable magnetostratigraphic record is found. Early Pleistocene (also known as Lower Pleistocene, or Calabrian) is a subdivision of the Pleistocene Epoch of the Geologic time scale
