The term Anthropocene, proposed and increasingly employed to denote the current interval of anthropogenic global environmental change, may be discussed on stratigraphic grounds.A case can made for its consideration as a formal epoch in that, since start Industrial Revolution, Earth has endured changes sufficient leave signature distinct from that Holocene or previous Pleistocene interglacial phases, encompassing novel biotic, sedimentary, geochemical change.These changes, although likely...
Abstract In June 2009, the Executive Committee of International Union Geological Sciences (IUGS) formally ratified a proposal by Commission on Stratigraphy to lower base Quaternary System/Period Global Stratotype Section and Point (GSSP) Gelasian Stage/Age at Monte San Nicola, Sicily, Italy. The until then had been uppermost stage Pliocene Series/Epoch. corresponds Marine Isotope Stage 103, has an astronomically tuned age 2.58 Ma. A that Pleistocene Series/Epoch be lowered coincide with (the...
Abstract Our understanding of how global climatic changes are translated into ice-sheet fluctuations and sea-level change is currently limited by a lack knowledge the configuration ice sheets prior to Last Glacial Maximum (LGM). Here, we compile synthesis empirical data numerical modelling results related pre-LGM produce new hypotheses regarding their extent in Northern Hemisphere (NH) at 17 time-slices that span Quaternary. reconstructions illustrate pronounced asymmetry within last glacial...
Abstract The term Anthropocene initially emerged from the Earth System science community in early 2000s, denoting a concept that Holocene Epoch has terminated as consequence of human activities. First associated with onset Industrial Revolution, it was then more closely linked Great Acceleration industrialization and globalization 1950s fundamentally modified physical, chemical, biological signals geological archives. Since 2009, been evaluated by Working Group, tasked examining for...
ABSTRACT Over the course of last decade concept Anthropocene has become widely established within and beyond geoscientific literature but its boundaries remain undefined. Formal definition as a chronostratigraphical series geochronological epoch following Holocene, at fixed horizon with precise global start date, been proposed, fails to account for diachronic nature human impacts on environmental systems during late Quaternary. By contrast, defining an ongoing geological event more closely...
This paper is based on a review of the histories Rivers Elbe, Saale, Weser, Rhine, Meuse, Scheldt, Thames, Somme and Seine. Two further rivers no longer in existence, Baltic Channel rivers, are also included. The these illustrate how interplay tectonics climate have influenced northwest European drainage system through late Cainozoic. foundations modern were laid Miocene when earth movements associated with Alpine orogenesis opening North Atlantic at their height. In general, early occupied...
Abstract The Early-Middle Pleistocene transition ( c. 1.2–0.5 Ma), sometimes known as the ‘mid-Pleistocene revolution’, represents a major episode in Earth history. Low-amplitude 41-ka obliquity-forced climate cycles of earlier were replaced progressively later by high-amplitude 100-ka cycles. These are indicative slow ice build-up and subsequent rapid melting, imply to strongly non-linear forced system. Changes accompanied substantially increased global volume at 940 ka. transformations,...
Glacial and periglacial landforms are widespread in the mountains of Mediterranean region. The evidence for glacial activity has been studied over 120 years it is possible to identify three phases development this area research. First, a pioneer phase characterized by initial descriptive observations landforms; second, mapping whereby detailed distribution sediments have depicted on geomorphological maps; and, third, an advanced understanding geochronology sequences using radiometric dating...

Sedimentological and palynological investigations of Great Songkhla Lakes, east coast the Malay-Thai Peninsula, Southeast Asia, reveal sedimentary sequences rich in palynomorph assemblages dominated by pollen mangroves freshwater swamps. Compared with other regions Asia are relatively low diversity. Geochronological data indicate that Lakes record one earliest mangrove environments (8420-8190 cal. yr BP), which subsequently replaced a swamp at 7880-7680 BP owing to decline marine influence....
SUMMARY The use of sodium pyrophosphate as an effective deflocculant for the removal clay from sediment samples is described. Tests on action chemical a number geographically and chronologically separated localities has shown almost complete clay. No evidence tests suggests that pollen attacked, preferentially destroyed or lost by this treatment.
competing proposals had been advanced: a 'Neogene' proposal advocated by the ICS Subcommission on Neogene Stratigraphy, and 'Quaternary' championed Quaternary Stratigraphy.The status quo
