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 ...

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. During the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roer Valley Graben
The Rur or Roer (german: Rur ; Dutch and li, Roer, , ; french: Rour) is a major river that flows through portions of Belgium, Germany and the Netherlands. It is a right (eastern) tributary to the Meuse ( nl, links=no, Maas). About 90 percent of the river's course is in Germany. It is not to be confused with the rivers Ruhr and Röhr, which are tributaries of the Rhine in North Rhine-Westphalia. Geography The Rur rises in the High Fens, near the high Signal de Botrange in Belgium at an elevation of above sea level. South of Monschau it flows into Germany, through North Rhine-Westphalia. It flows first through the northern part of the Eifel mountains. After it reaches the Rur Reservoir, the second-largest artificial lake in Germany. After approximately it flows into the Netherlands, and at its mark it flows into the river Meuse in the town of Roermond. Major tributaries of the Rur include the Inde and the Wurm. The towns along the Rur are Monschau, Heimbach, Nideg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrite
The mineral pyrite (), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula Iron, FeSulfur, S2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral. Pyrite's metallic Luster (mineralogy), luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of ''fool's gold''. The color has also led to the nicknames ''brass'', ''brazzle'', and ''Brazil'', primarily used to refer to pyrite found in coal. The name ''pyrite'' is derived from the Greek language, Greek (), 'stone or mineral which strikes fire', in turn from (), 'fire'. In ancient Roman times, this name was applied to several types of stone that would create sparks when struck against steel; Pliny the Elder described one of them as being brassy, almost certainly a reference to what we now call pyrite. By Georgius Agricola's time, , the term had become a generic term for all of the pyrite group, sulfide minerals. Pyrite is usua ...

Cliff
In geography and geology, a cliff is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs. An escarpment (or scarp) is a type of cliff formed by the movement of a geologic fault, a landslide, or sometimes by rock slides or falling rocks which change the differential erosion of the rock layers. Most cliffs have some form of scree slope at their base. In arid areas or under high cliffs, they are generally exposed jumbles of fallen rock. In areas of higher moisture, a soil slope may obscure the talus. Many cliffs also fea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glauconite
Glauconite is an iron potassium phyllosilicate ( mica group) mineral of characteristic green color which is very friable and has very low weathering resistance. It crystallizes with a monoclinic geometry. Its name is derived from the Greek () meaning 'bluish green', referring to the common blue-green color of the mineral; its sheen ( mica glimmer) and blue-green color. Its color ranges from olive green, black green to bluish green, and yellowish on exposed surfaces due to oxidation. In the Mohs scale it has hardness of 2. The relative specific gravity range is 2.4 - 2.95. It is normally found in dark green rounded brittle pellets, and with the dimension of a sand grain size. It can be confused with chlorite (also of green color) or with a clay mineral. Glauconite has the chemical formula . Glauconite particles are one of the main components of greensand, glauconitic siltstone and glauconitic sandstone. Glauconite has been called a marl in an old and broad sense of that word. ...

Mica
Micas ( ) are a group of silicate minerals whose outstanding physical characteristic is that individual mica crystals can easily be split into extremely thin elastic plates. This characteristic is described as perfect basal cleavage. Mica is common in igneous and metamorphic rock and is occasionally found as small flakes in sedimentary rock. It is particularly prominent in many granites, pegmatites, and schists, and "books" (large individual crystals) of mica several feet across have been found in some pegmatites. Micas are used in products such as drywalls, paints, fillers, especially in parts for automobiles, roofing and shingles, as well as in electronics. The mineral is used in cosmetics and food to add "shimmer" or "frost." Properties and structure The mica group is composed of 37 phyllosilicate minerals. All crystallize in the monoclinic system, with a tendency towards pseudohexagonal crystals, and are similar in structure but vary in chemical composition. Micas are ...

Rupel Formation
The Rupel Formation (abbreviation: RU) is a geologic formation in the subsurface of the Netherlands that consists of Oligocene marine sands and clays. The Rupel Formation is part of the Middle North Sea Group and correlates exactly with the Belgian Rupel Group. Name The Rupel Formation was first described by André Hubert Dumont in 1849. The formation is taken from Belgian lithostratigraphy, although it is considered a group in Belgium. The age in which the formation formed is the Rupelian (34 to 28 million years ago), a subdivision of the Oligocene epoch. The age and the formation are both named after the Belgian river Rupel. Facies and lithologies The Rupel Formation can be 250 meters thick at maximum. During the Rupelian age the Netherlands (and Belgium) were covered by a shallow sea, which became deeper towards the northwest. In the northwest, the sedimentary facies can be more than 500 m deep marine, while in southeastern parts of the Netherlands the formation has a nea ...

Eigenbilzen Formation
Eigenbilzen is a village and former municipality in the Bilzen municipality of the Limburg province in the Flemish Community of Belgium. Eigenbilzen was an independent municipality until 1977 when it merged into Bilzen. History The village was first mentioned in 1096 as Eigenbilesen. Prehistoric and Roman remains have been discovered in the area. In 1871 a tumulus was discovered at the Kannesberg which dated from 400 B.C. Furthermore three Roman villas, and a Roman cemetery were discovered. The Roman road connecting Tongeren to Maastricht used to pass through the village. was built in 1423. In 1680, the family of de Heusch de Zangerye became manor of the village, and resided in the castle. The castle was torn down in the early 19th century.

Limburg (Belgium)
Limburg ( nl, Limburg, ; li, Limburg or ''Wes-Limburg'' ; french: Limbourg, ) is a province in Belgium. It is the easternmost of the five Dutch-speaking provinces that together form the Region of Flanders, one of the three main political and cultural sub-divisions of modern-day Belgium. Limburg is located west of the Meuse ( nl, Maas), which separates it from the similarly-named Dutch province of Limburg. To the south it shares a border with the French-speaking province of Liège, with which it also has historical ties. To the north and west are the old territories of the Duchy of Brabant. Today these are the Flemish provinces of Flemish Brabant and Antwerp to the west, and the Dutch province of North Brabant to the north. The province of Limburg has an area of which comprises three arrondissements (''arrondissementen'' in Dutch) containing 44 municipalities.
