A. Penck

A. Penck  

(1858–1945)A German mineralogist from the University of Berlin, Penck's main interest was in Quaternary glacial land-forms, which he classified according to shape. Some of his work was done in ...
Anglian

Anglian  

1 A glacial stage of the middle Pleistocene in Britain.2 A middle Pleistocene, cold-climate series of deposits. There were a number of glacial advances in East Anglia (England), which are difficult ...
bevelled cliff

bevelled cliff  

A sea cliff whose upper part has been trimmed to a relatively low angle by Quaternary periglacial processes, while the lower part is still steep as a result of recent marine activity. Such cliffs are ...
BP

BP  

Initials which stand for ‘before present’ and relate to dates before the present day (taken conventionally to be 1950). The term should not be confused with ‘bc’, which relates to dates prior to the ...
Brunhes

Brunhes  

A palaeomagnetic chron, characterized by normal magnetization, in which we are living at present. It began about 780 000 years ago.
Caenozoic Era

Caenozoic Era  

Reference type:
Overview Page
Subject:
Archaeology
[CP]The latest era of the earth's geological history, from about 2 million years ago back to about 65 million years ago, which includes the Tertiary and Quaternary periods. Preceded by the Mesozoic.
Calabrian

Calabrian  

An early Pleistocene marine stage, about 1.806–0.781 Ma ago; it is noted for major evolutionary changes in mammalian faunas, which are split between two land-mammal stages (Upper Villafranchian and ...
Castlecliffian

Castlecliffian  

A series (0.01143–1.1 Ma ago) in the Quaternary of New Zealand, underlain by the Nukumaruan, overlain by the Holocene, and roughly contemporaneous with the uppermost Calabrian and Emilian Stages, and ...
Cenozoic

Cenozoic  

The most recent era of earth's history stretching approximately from 65 million years bp to the present day.http://www.ucmp.berkeley.edu/cenozoic/cenozoic.html An overview of the Cenozoic period.
Climate/Long-range Investigation Mapping and Predictions Project

Climate/Long-range Investigation Mapping and Predictions Project  

(CLIMAP)An international research project during the 1970s and 1980s that reconstructed the Earth's climate over the last million years and produced maps of sea‐surface temperature at various ...
climatostratigraphy

climatostratigraphy  

The study of geologic–climatic units, which are climatic episodes defined in Quaternary rocks. They are similar to chronostratigraphic units (i.e. they are inferential), but their boundaries are ...
cotectic surface

cotectic surface  

Curved surface in a quaternary system which defines the temperature range over which two or more solid phases crystallize simultaneously from a liquid. Analagous to a cotectic line in a ternary ...
Cromerian

Cromerian  

1 A northern European interglacial stage dating from about 0.6–0.55 Ma ago. It coincides approximately with the Günz/Mindel interglacial of the Alps.2 Temperate deposits of Middle Pleistocene age ...
Dansgaard–Oeschger (D–O) cycles

Dansgaard–Oeschger (D–O) cycles  

Very rapid climate changes—up to 7 °C in some fifty years—during the Quaternary period, especially during the most recent glacial cycle. The cause of D–O cycles has yet to be comprehensively ...
deep-sea core

deep-sea core  

Reference type:
Overview Page
Subject:
Archaeology
[Ge]A narrow column of sediments taken by drilling into the sea‐bed with a piston‐corer. Such cores can provide a more or less complete record of climatic changes through the Quaternary. The ...
denudation chronology

denudation chronology  

Branch of land-form studies that deals with the historical development of landscapes by denudation, especially during pre-Quaternary time. Evidence for developmental stages is provided by studies of ...
Devensian Stage

Devensian Stage  

Reference type:
Overview Page
Subject:
Archaeology
[Ge]A group of deposits representing a geostratigraphic stage within the Pleistocene series of the British Quaternary System, dating to the period betwen 120 000 and 10 000 years ago. The Devensian ...
epoch

epoch  

An interval of geological time; several epochs form a period, several periods an era. An epoch is ranked as a third-order time unit (M. Allaby2006).
Flandrian

Flandrian  

The present interglacial, during which there has been a global rise in sea level—the Flandrian transgression, caused by the melting of ice sheets and glaciers (Smith et al. (2006) ESPL 8, 5). The ...
Holocene

Holocene  

The most recent geological epoch, stretching from 12 000 years ago to the present day. See Fisch in H. von Stoch et al., eds (2004).
