Sedimentary Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics (lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob Werne ...

Landen Group
The Landen Group is a lithostratigraphic unit (a "group" of rock strata) in the Belgian subsurface. The group consists of two formations of Thanetian (late Paleocene The Paleocene, ( ) or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), E ...) to Ypresian (early Eocene) age. The Landen Group is named after the town of Landen in Flemish Brabant. Subdivision The Landen Group is subdivided into two formations: * The Hannut Formation, an alternation of marine (ocean), marine clays, sands and limestones; * The Tienen Formation, a lagoonal-continental alternation of clay, sand and lignite. This formation is known for its fossils. Both formations can be found in the subsurface of all northern Belgium. They outcrop, crop out in the Hainaut (province), province of Hainaut.

Voort Formation
The Voort Formation or Voort Member ( nl, Formatie van Voort or ; abbreviation in Belgium: Vo or in the Netherlands: VEVO) is a stratigraphic unit in the subsurface of north Belgium and the south of the Netherlands. The unit has the status of a formation in Belgium but is seen as a member of the Veldhoven Formation in the Netherlands. The Voort Formation consists of shallow marine sands with a late Oligocene age ( Chattian stage, about 25 million years old). Stratigraphy In Belgian lithostratigraphy the Voort Formation is part of the Rupel Group, though other formations in this group are slightly older (of the early Oligocene Rupelian stage). In the Netherlands the Voort Member is part of the Veldhoven Formation. In Belgium, a clayey subunit is treated as a member of the Voort Formation ( Veldhoven Member). In Dutch lithostratigraphy, this unit is classified as another member of the Veldhoven Formation and called the Wintelre Member. In Belgium the Voort Formation is stratigra ...

Tongeren Group
The Tongeren Group is a lithostratigraphic unit (a sequence of rock strata) in the subsurface of Belgium. It consists of shallow marine, epicontinental and/or continental clays and sands from the late Eocene to early Oligocene epochs (between 37 and 30 million years old). The Belgian Tongeren Group correlates with the Dutch Tongeren Formation. The name was introduced by André Hubert Dumont in 1849. Subdivision The Tongeren Group is subdivided into three formations. From top to bottom these are: *the Borgloon Formation, lagunal or fluvial shell rich sand and clay; *the Sint Huibrechts-Hern Formation, marine shell bearing sand and clay; *the Zelzate Formation, shallow marine glauconiferous sand with thin clay layers. Stratigraphic relations In northwest Belgium the Tongeren Group (represented in that area mostly by the Zelzate Formation) is stratigraphically lying on top of the Maldegem Formation (middle Eocene clay and sand). This formation is lacking in the east of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tielt Formation
The Tielt Formation ( nl, Formatie van Tielt; french: Formation de Tielt; abbreviation: Tt; named after the town of Tielt in West Flanders) is a geologic formation in the subsurface of Belgium. The formation crops out in the north of Hainaut, in the southern and central parts of West- and East Flanders and in Walloon and Flemish Brabant. It consists of marine very fine sand and silt, deposited in the shallow sea that covered Belgium during the middle and late Ypresian age (early Eocene, about 53 million years ago).Steurbaut, 2006, p.76Tielt Formation - National Commission on the Stratigraphy of Belgium Description The Tielt Formation is thick at most.

Tienen Formation
The Tienen Formation ( nl, Formatie van Tienen; french: Formation de Tienen; abbreviation: Ti) is a geologic formation in the subsurface of northern Belgium. The formation crops out in the province of Hainaut and the Hesbaye region in the province of Limburg. It has a late Thanetian (Paleocene) to early Ypresian (Eocene) age. The Tienen Formation consists of clay with thin lignite layers and lithified wood, sand (sometimes with shells) and marl. It has a continental to lagoonal sedimentary facies. The formation is a lagerstätte for fossils of vertebrate animals. The Tienen Formation forms together with the older marine clays and sands of the Hannut Formation the Landen Group The Landen Group is a lithostratigraphic unit (a "group" of rock strata) in the Belgian subsurface.

Oligocene
The Oligocene ( ) is a geologic epoch of the Paleogene Period and extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from the Ancient Greek (''olígos'', "few") and (''kainós'', "new"), and refers to the sparsity of extant forms of molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major changes during the Oligocene included a global expansion o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rupel Group
The Rupel Group is a stratigraphic group of rock strata in the subsurface of Belgium. It is subdivided into three formations that are all marine deposits (sands and clays) of Oligocene age. Name The Rupel Group was first named by Belgian geologist André Hubert Dumont in 1849. It shares its name with the Rupelian age (34 to 28 million years ago) of the geological timescale. Both group and age are named after the Belgian river Rupel. The Rupel Group corresponds with the Rupel Formation in the Netherlands. Facies and lithologies The Rupel Group can be 250 meters thick at maximum. During the Rupelian age Belgium was covered by a shallow sea. The formations of the Rupel Group therefore have a shallow marine to near coastal facies. Stratigraphy The group is subdivided into three formations: the Bilzen Formation (yellow-white glauconiferous fine sand, containing fossils), the Boom Formation (a thick clay deposit, containing loam layers and septaria) and the Eigenbilzen Formation ...

Opglabbeek Formation
The Opglabbeek Formation is a geologic formation in the subsurface of the eastern part of Belgian Limburg. The heterogeneous formation consists of clay and sand that was deposited lagoonally and fluvially during the early Selandian (Middle Paleocene, about 60 million years old). The formation is named after the town of Opglabbeek in Limburg. The Opglabbeek Formation is subdivided into two members: the Opoeteren Member (red clay with layers of lignite) and the Eisden Member (fine sand with crags). The Opglabbeek Formation's thickness ranges between and , reaching its greatest thickness as it abuts the Roer Valley Graben. It lies stratigraphically on top of the Houthem Formation (early Paleocene calcareous sandstone). It is the lateral equivalent of the Hainin Formation. On top of it lies the Heers Formation (Middle Paleocene sands and marls). The Opglabbeek Formation is part of the Hesbaye Group and can be correlated with parts of the Landen Formation of adjacent areas i ...

Lede Formation
The Lede Formation ( nl, Formatie van Lede; abbreviation: Ld) is a geologic formation in the subsurface of Belgium. The formation is named after the town of Lede in East Flanders. It consists of shallow-marine limestone and sandstone, deposited in the former sea that covered Belgium during the Eocene. The Lede Formation crops out in East Flanders, Flemish Brabant, Antwerp and parts of Hainaut, Walloon Brabant and West Flanders. It forms a laterally continuous unit of calcareous and glauconiferous sandstone, sandy limestone and calcareous sandstone, which reaches a thickness of up to 15 metres. The formation is characterised by fossils of the nummulite '' Nummulites variolarius''. It is not subdivided into members. The age of the Lede Formation is middle Lutetian (about 44 million years old) and it is part of the Zenne Group.
