Wolstonian Stage
The Wolstonian Stage is a middle Pleistocene stage of the geological history of Earth from approximately 374,000 until 130,000 years ago. It precedes the Last Interglacial (also called the Eemian Stage) and follows the Hoxnian Stage in the British Isles. It is also approximately analogous to the Warthe and Saalian stages in northern Europe; the Riss glaciation in the Alps; and the Illinoian Stage in North America. The colder last part from around 194,000 years ago is called the Penultimate Glacial Period. It is equivalent to Marine isotope stages (MIS) 10 through 6. MIS 10, 8 and 6 were glacial periods and 9 and 7 were interglacials. It is named after Wolston in the English county of Warwickshire. Description The Wolstonian Stage is a middle Pleistocene stage of the geological history of Earth that precedes the Ipswichian Stage (Eemian Stage in Europe) and follows the Hoxnian Stage in the British Isles. The Wolstonian Stage apparently includes three periods of glac ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Hoxnian Stage
__NOTOC__ The Hoxnian Stage was a middle Pleistocene stage of the geological history of the British Isles. It was an interglacial which preceded the Wolstonian Stage and followed the Anglian Stage. It is equivalent to Marine Isotope Stage 11 (MIS 11). Marine Isotope Stage 11 started 424,000 years ago and ended 374,000 years ago. Lisiecki, L. E. (2005)Ages of MIS boundaries.http://www.lorraine-lisiecki.com/stack.html LR04 Benthic Stack] Boston University, Boston, MA The Hoxnian is divided into sub-stages Ho I to Ho IV. It is likely equivalent to the Holstein Interglacial in Central Europe. History The Hoxnian Stage is named after Hoxne in the English county of Suffolk where some of the deposits created were first found. It was identified and dated with palynology or pollen evidence in the biostratigraphy and later updated with aminostratigraphic techniques. Based on stratigraphic information the Hoxnian happened after the Anglian glacial as Anglian soil is frequently found und ...

Europe
Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and Asia to the east. Europe shares the landmass of Eurasia with Asia, and of Afro-Eurasia with both Africa and Asia. Europe is commonly considered to be Boundaries between the continents#Asia and Europe, separated from Asia by the Drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea, and the waterway of the Bosporus, Bosporus Strait. "Europe" (pp. 68–69); "Asia" (pp. 90–91): "A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Black Sea with its outlets, the Bosporus and Dardanelles."

Anglian Stage
The Anglian Stage is the name used in the British Isles for a middle Pleistocene glaciation. It precedes the Hoxnian Stage and follows the Cromerian Stage in the British Isles. It correlates to Marine Isotope Stage 12 (MIS 12), which started about 478,000 years ago and ended about 424,000 years ago. Lisiecki, L.E. (2005Ages of MIS boundaries.

Saalian
The Saale glaciation or Saale Glaciation, sometimes referred to as the Saalian glaciation, Saale cold period (), Saale complex (''Saale-Komplex'') or Saale glacial stage (called the Wolstonian Stage in Britain), covers the middle of the three large glaciations in Northern Europe and the northern parts of Eastern Europe, Central Europe and Western Europe by the Scandinavian Inland Ice Sheet. It follows the Holstein interglacial (Hoxnian Stage in Britain) and precedes the Eemian interglacial (globally known as the Last Interglacial and the Ipswichian in Britain), spanning from around 400,000 years ago to 130,000 years ago. The Saalian covers multiple glacial cycles punctuated by interglacial periods. In its latter part it is coeval with the global Penultimate Glacial Period. Age and definitions The Saalian succeeded the Holstein interglacial and was followed by the Eemian interglacial (which began around 130,000 years ago) Though the start date of the Saalian was historically co ...

Elsterian
The Elster glaciation (, ''Elster-Glazial'' or ''Elster-Zeit'') or, less commonly, the Elsterian glaciation, in the older and popular scientific literature also called the Elster Ice Age (''Elster-Eiszeit''), is the oldest known ice age that resulted in the large-scale glaciation of North Germany and other parts of Europe. It took place approximately 500,000–400,000 years ago. It succeeded a long period of rather warmer average temperatures, the Cromerian Complex. The Elster was followed by the Holstein interglacial, which was followed Saale glaciation. The glacial period is named after the White Elster, a right tributary of the Saale. Controversial correlations Traditionally, Elster was correlated with the Mindel glaciation of the Alps and the Anglian glaciation of Great Britain and Ireland. Analysis in the 1950s of oxygen isotopes in deep sea core samples introduced a global glacial history, with warm and cold phases identified by marine isotope stages (MIS). This ident ...

Eburonian
The Eburonian ( or ''Eburonium''), or, much less commonly, the Eburonian Stage, is a glacial complex in the Calabrian age of the Pleistocene epoch and lies between the Tegelen and the Waalian interglacial. The transition from the Tegelen to the Eburonian started about 1.78 million years ago, lasted 480,000 years (to 1.3 million years ago). In geologic strata, at its base, from its startpoint, the Neogene underlies different Gelasian deposits starkly in much of the Netherlands.Hey, R. W. ''The Plio-Pleistocene of England and Iceland'' in Van Couvering, John A. (editor), (1997) ''The Pleistocene Boundary and the Beginning of the Quaternary'', Cambridge, Cambridge University Press, p. 183. . Discovery As early as the 1920s, the names of the three well known glaciations - the Elster, the Saale and the Weichselian - had become established at the recommendation of Konrad Keilhack and Paul Woldstedt.

Würm Glaciation
The Würm glaciation or Würm stage ( or ''Würm-Glazial'', colloquially often also ''Würmeiszeit'' or ''Würmzeit''; cf. ice age), usually referred to in the literature as the Würm (often spelled "Wurm"), was the last glacial period in the Alpine region. It is the youngest of the major glaciations of the region that extended beyond the Alps themselves. Like most of the other ice ages of the Pleistocene epoch, it is named after a river, in this case the Würm in Bavaria, a tributary of the Amper. The Würm ice age can be dated to about 115,000 to 11,700 years ago. Sources differ about the dates, depending on whether the long transition phases between the glacials and interglacials (warmer periods) are allocated to one or other of those periods. The average annual temperatures during the Würm ice age in the Alpine Foreland were below −3 °C (today +7 °C). That has been determined from changes in the vegetation ( pollen analysis), as well as differences in the ...

Mindel Glaciation
The Mindel glaciation (, also ''Mindel-Glazial'', ''Mindel-Komplex'' or, colloquially, ''Mindel-Eiszeit'') is the third youngest glacial stage in the Alps. Its name was coined by Albrecht Penck and Eduard Brückner, who named it after the Swabian river, the Mindel. The Mindel glacial occurred in the Middle Pleistocene; it was preceded by the Haslach-Mindel interglacial (often regarded as part of Günz) and succeeded by the Mindel-Riss interglacial ( Holstein interglacial). The Mindel glaciation is commonly correlated with the Elster glaciation of northern Europe. The more precise timing is controversial since Mindel is commonly correlated to two different marine isotope stages, MIS 12 (478–424 thousand years ago ) and MIS 10 (374–337 thousand years ago). This ambiguity is much related to the correlation problem described in more detail in the article ' Elster glaciation'.

Gunz Glaciation
Gunz, Günz or Gunz Complex is a timespan in the glacial history of the Alps. It started approximately one million years ago and ended about 370 000 years ago. Some sources put the end at 480 000 years ago. Deep sea core samples have identified approximately 5 glacial cycles of varying intensity during Gunz. History of the term The name Gunz glaciation, Gunzian glaciation or Günz glacial stage (, also ''Günz-Glazial'', ''Günz-Komplex'' and ''Günz-Eiszeit'') goes back to Albrecht Penck and Eduard Brückner, who named this ice age after the River Günz in their multi-volume work, ''Die Alpen im Eiszeitalter'' ("The Alps in the Ice Age Period") which was published between 1901 and 1909. Its type region is the Iller-Lech Plateau. It is the oldest glaciation of the Pleistocene in the traditional, quadripartite glacial classification of the Alps. The Günz was thought to follow the Danube-Günz interglacial and was ended by the Günz-Haslach interglacial. The 2016 version of t ...
