Geological unit — A geological unit is a volume of rock or ice of identifiable origin and age range that is defined by the distinctive and dominant, easily mapped and recognizable petrographic, lithologic or paleontologic features (facies) that characterize it.… … Wikipedia
Lithostratigraphy — is a sub dicipline of stratigraphy, the geological science associated with the study of strata or rock layers. Major focuses include geochronology, comparative geology, and petrology. In general a stratum will be primarily igneous or sedimentary… … Wikipedia

Series (stratigraphy) — Series are subdivisions of rock layers made based on the age of the rock. A series is therefore a chronostratigraphic unit, unrelated to lithostratigraphy, which divides rock layers on their lithology. Series are subdivisions of systems and are… … Wikipedia
bed — [ stratigraphy ] The layer of sediments or sedimentary rocks bounded above and below by more or less well defined bedding surfaces. The smallest, formal lithostratigraphic unit of sedimentary rocks. The designation of a bed or a unit of… … Glossary of landform and geologic terms
Chalk Group — The Needles, part of the extensive Southern England Chalk Formation. The Chalk Group (often just called the Chalk) is a lithostratigraphic unit (a certain number of rock strata) in the northwestern part of Europe. It is characterised by thick… … Wikipedia
Stage (stratigraphy) — In chronostratigraphy, a stage is a succession of rock strata laid down in an single age on the geologic timescale, which usually represents millions of years of deposition. A given stage of rock and the corresponding age of time will by… … Wikipedia
Lias Group — The Lias Group or Lias is a lithostratigraphic unit (a sequence of rock strata) found in a large area of western Europe, including the British Isles, the North Sea, the low countries and the north of Germany. It consists of marine limestones,… … Wikipedia
Flysch — is a sequence of sedimentary rocks that is deposited in a deep marine facies in the foreland basin of a developing orogen. Flysch is typically deposited during an early stage of the orogenesis, when the orogen evolves the foreland basin will… … Wikipedia
Bed (geology) — In geology a bed is the smallest division of a geologic formation or stratigraphic rock series marked by well defined divisional planes (bedding planes) separating it from layers above and below. A bed is the smallest lithostratigraphic unit,… … Wikipedia
Group (stratigraphy) — A group is in stratigraphy a lithostratigraphic unit, a part of the geologic record or rock column that consists of defined rock strata. Groups are divided into formations (and sometimes into subgroups ) and are sometimes themselves grouped into… … Wikipedia
