Geology Of Hungary
Hungary is in the Pannonian Basin in Central Europe, is surrounded by the Carpathians, Alps and Dinarides, but for the most part dominated by lowlands. Sixty-eight percent of the country is lowlands below 200 meters altitude. Hilly terrain covers 30% of the country, while mountains cover only 2%. The entire Pannonian Basin is in the Danube watershed. Tectonics and bedrock geology Hungary is mostly defined by Late Cenozoic geologic evolution. Large back-arc basins formed due to anomalous crust thinning and a high geothermal gradient. The Pannonian Basin is actually a system of basins, including the Great Plain Basin, the Vienna Basin, the Drava Basin and the Transylvanian Basin. The different sub-basins are separated by inselberg ranges, made of Paleozoic, Mesozoic, and Paleogene sedimentary rocks and Cenozoic igneous and sedimentary rocks. The Eastern Alps extend into the northwest of Hungary as the Sopron and Kőszeg mountains, near the Austrian border and are made up of metamo ...

Mecsek
Mecsek (; ; Serbian language, Serbian: ''Meček'' or Мечек; ) is a mountain range in southern Hungary. It is situated in the Baranya (region), Baranya region, in the north of the city of Pécs. Etymology The Hungarian toponym "Mecsek" derives from the sobriquet version of the name Mihály (Michael). Originally applied only to the hills adjacent to Pécs, the name Mecsek was first mentioned in 16th century. Geography The mountains cover an area of approximately 500 km2. The highest peak in the mountain range is Zengő (literally translates to 'resonant'), which has an elevation of 682 metres (2,238 feet). The Mecsek Hills consist of plateau-like block mountains of a broken, folded structure. Its basis is crystalline rock of Variscan origin surmounted by Triassic and Jurassic limestone and dolomite and Tertiary formations that form the main block. The mountains are divided by a structural fault running NW to SE. The eastern part consists mainly of high ridges of sedi ...

Early Cretaceous
The Early Cretaceous (geochronology, geochronological name) or the Lower Cretaceous (chronostratigraphy, chronostratigraphic name) is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 143.1 Megaannum#SI prefix multipliers, Ma to 100.5 Ma. Geology Proposals for the exact age of the Barremian–Aptian boundary ranged from 126 to 117 Ma until recently (as of 2019), but based on drillholes in Svalbard the defining Anoxic event#Cretaceous, early Aptian Oceanic Anoxic Event 1a (OAE1a) was dated to 123.1±0.3 Ma, limiting the possible range for the boundary to c. 122–121 Ma. There is a possible link between this anoxic event and a series of Early Cretaceous large igneous provinces (LIP). The Ontong Java Plateau, Ontong Java-Manihiki Plateau, Manihiki-Hikurangi Plateau, Hikurangi large igneous province, emplaced in the South Pacific at c. 120 Ma, is by far the largest LIP in Earth's history.

Barremian
The Barremian is an age in the geologic timescale (or a chronostratigraphic stage) between 125.77 Ma (million years ago) and 121.4 ± 1.0 Ma (Historically, this stage was placed at 129.4 million to approximately 125 million years ago) It is a subdivision of the Early Cretaceous Epoch (or Lower Cretaceous Series). It is preceded by the Hauterivian and followed by the Aptian Stage.See Gradstein ''et al.'' (2004) or the online geowhen database (link below) Stratigraphic definitions The original type locality for the Barremian Stage is in the vicinity of the village of Barrême, Alpes-de-Haute-Provence, France. Henri Coquand defined the stage and named it in 1873. The base of the Barremian is determined by the first appearance of the ammonites '' Spitidiscus hugii'' and ''Spitidiscus vandeckii''. The end of the Barremian is determined by the geomagnetic reversal at the start of the M0r chronozone, which is biologically near the first appearance of the ammonite '' Paradesh ...

Lignite
Lignite (derived from Latin ''lignum'' meaning 'wood'), often referred to as brown coal, is a soft, brown, combustible sedimentary rock formed from naturally compressed peat. It has a carbon content around 25–35% and is considered the lowest rank of coal due to its relatively low heat content. When removed from the ground, it contains a very high amount of moisture, which partially explains its low carbon content. Lignite is mined all around the world and is used almost exclusively as a fuel for steam-electric power generation. Lignite combustion produces less heat for the amount of carbon dioxide and sulfur released than other ranks of coal. As a result, lignite is the most harmful coal to human health. Depending on the source, various toxic heavy metals, including naturally occurring radioactive materials, may be present in lignite and left over in the coal fly ash produced from its combustion, further increasing health risks. Characteristics Lignite is brownish-bl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bauxite
Bauxite () is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (), boehmite (γ-AlO(OH)), and diaspore (α-AlO(OH)), Mixture, mixed with the two iron oxides goethite (FeO(OH)) and haematite (), the aluminium Clay minerals, clay mineral kaolinite () and small amounts of anatase () and ilmenite ( or ). Bauxite appears dull in Lustre (mineralogy), luster and is reddish-brown, white, or tan. In 1821, the French people, French geologist Pierre Berthier discovered bauxite near the village of Les Baux-de-Provence, Les Baux in Provence, southern France. Formation Numerous classification schemes have been proposed for bauxite but, , there was no consensus. Vadász (1951) distinguished Laterite, lateritic bauxites (silicate bauxites) from karst bauxite ores (carbonate bauxites): * The carbonate bauxites occur predominantly in Europe, Guyana, Suriname, and ...

Treaty Of Trianon
The Treaty of Trianon (; ; ; ), often referred to in Hungary as the Peace Dictate of Trianon or Dictate of Trianon, was prepared at the Paris Peace Conference (1919–1920), Paris Peace Conference. It was signed on the one side by Hungary and, on the other, by the Allied and Associated Powers, in the Grand Trianon château in Versailles on 4 June 1920. It formally terminated the state of war issued from World War I between most of the Allies of World War I and the Kingdom of Hungary. The treaty is famous primarily due to the territorial changes imposed on Hungary and recognition of its new international borders after the First World War. As part of the Austria-Hungary, Austro-Hungarian Empire, Hungary had been involved in the First World War since August 1914. After its allies – Bulgaria and later Turkey – Armistice of Salonica, signed armistices with the Entente, the political elite in Budapest also opted to end the war.

Loránd Eötvös
Baron Loránd Eötvös de Vásárosnamény (or simply Loránd Eötvös ; ; ; 27 July 1848 – 8 April 1919), also called Baron Roland von Eötvös in English literature, was a Hungarian physicist. He is remembered today largely for his work on gravitation and surface tension, and the invention of the torsion pendulum. In addition to Eötvös Loránd University and the Eötvös Loránd Institute of Geophysics in Hungary, the Eötvös crater on the Moon, the asteroid 12301 Eötvös and the mineral lorándite also bear his name, as well as a peak (Cima Eotvos) in the Dolomites. Life Born in 1848, the year of the Hungarian revolution, Eötvös was the son of the Baron József Eötvös de Vásárosnamény (1813–1871), a well-known poet, writer, and liberal politician, who was cabinet minister at the time, and played an important part in 19th century Hungarian intellectual and political life.

Austro-Hungarian Empire
Austria-Hungary, also referred to as the Austro-Hungarian Empire, the Dual Monarchy or the Habsburg Monarchy, was a multi-national constitutional monarchy in Central Europe between 1867 and 1918. A military and diplomatic alliance, it consisted of two sovereign states with a single monarch who was titled both the Emperor of Austria and the King of Hungary. Austria-Hungary constituted the last phase in the constitutional evolution of the Habsburg monarchy: it was formed with the Austro-Hungarian Compromise of 1867 in the aftermath of the Austro-Prussian War, following wars of independence by Hungary in opposition to Habsburg rule. It was dissolved shortly after Hungary terminated the union with Austria in 1918 at the end of World War 1. One of Europe's major powers, Austria-Hungary was geographically the second-largest country in Europe (after Russia) and the third-most populous (after Russia and the German Empire), while being among the 10 most populous countries worldwide.
