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 ...

Group (stratigraphy)
In geology, a group is a lithostratigraphic unit consisting of a series of related formations that have been classified together to form a group. Formations are the fundamental unit of stratigraphy. Groups may sometimes be combined into supergroups. Groups are useful for showing relationships between formations, and they are also useful for small-scale mapping or for studying the stratigraphy of large regions. Geologists exploring a new area have sometimes defined groups when they believe the strata within the groups can be divided into formations during subsequent investigations of the area. It is possible for only some of the strata making up a group to be divided into formations. An example of a group is the Glen Canyon Group, which includes (in ascending order) the Wingate Sandstone, the Moenave Formation, the Kayenta Formation, and the Navajo Sandstone. Each of the formations can be distinguished from its neighbor by its lithology, but all were deposited in the same vast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loam
Loam (in geology and soil science) is soil composed mostly of sand (particle size > ), silt (particle size > ), and a smaller amount of clay (particle size < ). By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay, respectively. These proportions can vary to a degree, however, and result in different types of loam soils: sandy loam, silty loam, clay loam, sandy clay loam, silty clay loam, and loam. In the , textural classification triangle, the only soil that is not predominantly sand, silt, or clay is called "loam". Loam soils generally contain more nutrients, moisture, and |
Kattendijk Formation
The Kattendijk Formation (also known as the Kattendijk Sands) is a five million years old marine geological formation north of Antwerp, Belgium. including the north-western parts of the Campine region. The area was named by De Heuter and Laga in 1976. The sands range from medium fine to coarse and contain a large proportion of shell grit. Geology The clay of the Rupelian era developed to a depth of approximately beneath a deposit of Neogene sand. The formation has a Miocene Era aquifer, while the clay level dates to the Pliocene. Palaeontology A Pliocene species of auk (''Alca stewarti'') was found in 2000. A small oceanic dolphin Oceanic dolphins or Delphinidae are a widely distributed family of dolphins that live in the sea. Close to forty extant species are recognised. They include several big species whose common names contain "whale" rather than "dolphin", such as the ..., '' Pliodelphis'', is also known from the formation.

Bolderberg Formation
Heusden-Zolder (; li, Heuze-Zolder ) is a municipality located in the Belgian province of Limburg near Hasselt. On 1 January 2006 Heusden-Zolder had a total population of 30,769. The total area is 53.23 km² which gives a population density of 578 inhabitants per km². Heusden-Zolder was the result of the merger on 1 January 1977 of the two former municipalities of Heusden and Zolder, and currently consists of the former Heusden parishes of Heusden centre, Berkenbos and Eversel, and the former Zolder parishes of Zolder centre, Boekt, Viversel, Bolderberg and Lindeman. Heusden-Zolder is home to almost 2,000 immigrants from all over the world. This is due to the (now closed) coal mine of Zolder. During the 1960s Belgian coal mines faced an enormous shortage of employees. To address this problem, foreigner labourers were encouraged to immigrate and work near the mines. After their closure (the mine in Zolder was the last one in Belgium, the Netherlands and Luxemburg to clos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berchem Formation
Berchem () is a southern district of the municipality and city of Antwerp in the Flemish Region of Belgium. Berchem is located along the old ''Grote Steenweg'' (Dutch for 'Big Paved Road') that has connected Brussels to Antwerp for several centuries; the town borders the districts of Deurne, Borgerhout, Wilrijk and Antwerp and the municipality of Mortsel. Berchem itself consists of three quarters, ''Oud Berchem'', ''Groenenhoek'' and ''Nieuw Kwartier''. The 'Ring', Antwerp's circular motorway which follows the track of the former city defense walls, cuts Berchem in two parts, separating the urban inner city area of Oud-Berchem (''intra muros'') from the more residential and suburban areas Groenenhoek, Pulhof and Nieuw Kwartier (''extra muros''). Political structure After the decentralization of Antwerp in 2000, Berchem became a semi-independent district with its own legislative body, the so-called Districtsraad (''District Council''), and its own executive college.

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.

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 ...

Maldegem Formation
The Maldegem Formation ( nl, Formatie van Maldegem; old name: Kallo Complex) is a geologic formation in the Belgian subsurface. The formation consists of alternating marine clay and sand strata, deposited during the late Eocene. The Maldegem Formation crops out in the provinces of East Flanders and West Flanders and in the area between the Zenne and Dender rivers. In the northern parts of Flanders it forms an up to 50 meters thick sequence in the subsurface. Further south and to the east (in the Campine of the province of Antwerp) the formation pinches out and can be only a few meters in thickness. Lithology The Maldegem Formation is an alternating sequence of grey glauconiferous fine sands and greyish blue glauconiferous heavy clay. It was deposited during the late Lutetian and Bartonian ages (between 42 and 37 million years old). Stratigraphy Seven members can be recognized within the Maldegem Formation: Wemmel Member, Asse Member, Ursel Member, Onderdale Member, Zome ...

Sint Huibrechts-Hern Formation
''Sint'' (released on DVD as ''Saint'' in Europe and ''Saint Nick'' in the United States) is a 2010 Dutch dark comedy horror film about Sinterklaas, the character on which the Anglo-Saxon Santa Claus is based. The film was directed by Dick Maas and marked his return to the horror genre, in which he gained acclaim with his debut ''De Lift'' (1983) and ''Amsterdamned'' (1988). The story distorts the popular traditions of Sinterklaas and portrays him as a ghost who murders large numbers of people when his annual celebration night coincides with a full moon. Plot On December 5th 1492, a gang led by former bishop Niklas is killed by villagers who refuse to put up with the gang's looting and killing any longer. In years in which the gang's death date coincides with a full moon, they return as murderous ghosts. The public is unaware of this and annually celebrates the Sinterklaas tradition on December 5th, with adults not believing that Sinterklaas exists but making little children ...

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] |
