abandonment facies association

abandonment facies association  

A facies association formed under conditions of rising sea level, when clastic deposition has ceased and sediment is deposited very slowly.
albite–epidote–amphibolite facies

albite–epidote–amphibolite facies  

A set of metamorphic mineral assemblages that is produced by the metamorphism of a wide range of initial rock types under the same metamorphic conditions, and is typically characterized by the ...
biofacies

biofacies  

A rock unit, or an association of rock units, that is characterized by the presence of a fossil assemblage restricted to that particular facies and typical of a specific environment.
chronostratigraphic correlation chart

chronostratigraphic correlation chart  

A graphic display summarizing the stratigraphy of a particular area. The vertical scale represents geologic time, the horizontal scale represents distance, and the time-range and geographic extent of ...
coarsening-upward succession

coarsening-upward succession  

A vertical change in a facies in which the grain size increases with height above the base. Compare fining-upward succession.
cyclic sedimentation

cyclic sedimentation  

A style of sedimentation where the sequence of sedimentary facies develops in a regular and repeated manner. The cycle of sediments may consist of two or more facies, and the cycles may be ...
Danian

Danian  

The oldest of the Cenozoic stages, about 65.5–61.7 Ma ago, which in Denmark is characterized by chalky limestone rich in reef-dwelling organisms. It is a problematic stage, once referred to the ...
depositional system

depositional system  

An assemblage of lithofacies (see also facies; facies association) formed within a particular depositional environment (e.g. fluvial).
Devonian

Devonian  

A period of Palaeozoic time stretching approximately from 395 to 345 million years bp.http://www.ucmp.berkeley.edu/devonian/devonian.html. An overview of the Devonian period.
elfin wood

elfin wood  

A facies of tropical upper montane or subalpine forest, with dwarfed and gnarled trees, that grows on extreme or exposed sites. The term is sometimes applied outside the tropics, although in this ...

facies association

facies association  

A group of sedimentary facies used to define a particular sedimentary environment. For example, all the facies found in a fluviatile environment may be grouped together to define a fluvial facies ...
facies sequence

facies sequence  

A vertical succession of facies; such sequences often fine or coarsen upwards, and may be repeated many times in a cyclic manner due to the migration of the facies through time and space.
fining-upward succession

fining-upward succession  

A vertical change in a facies in which the grain size decreases with height above the base. Compare coarsening-upward succession.
flysch

flysch  

A soft, easily erodable, series of alternating clays, shales, and sandstones. The Carpathian flysch have been intensively studied: see Margielewski (2006) Geomorph. 77, 1–2.
Friedrich Johann Karl Becke

Friedrich Johann Karl Becke  

(1855–1931)A Czechoslovakian mineralogist and petrologist from the University of Prague, Becke developed a method for determining the relative refraction of light in microscopy, later named for him. ...
genetic stratigraphic unit

genetic stratigraphic unit  

A large-scale set of facies sequences, which were formed by slow deposition and are bounded by breaks in sedimentation, which can be related to one another for purposes of analysis and interpretation.
glaucony

glaucony  

A green-coloured, marine sedimentary facies characterized by the presence of grains of the glauconite mineral family, which develop on continental margins and on ocean highs. Glaucony is of variable ...
glaucophane-schist facies

glaucophane-schist facies  

A set of metamorphic mineral assemblages produced by metamorphism of a wide range of starting rock types under the same high-pressure/low-temperature metamorphic conditions and typically ...
interdigitating

interdigitating  

Applied to a facies boundary where the line of lithological change between one sedimentary rock type and the next laterally adjacent rock type is itself broken down into a series of wedge-shaped ...
