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 metamorp ...

Pannonian Basin
The Pannonian Basin, or Carpathian Basin, is a large Sedimentary basin, basin situated in south-east Central Europe. The Geomorphology, geomorphological term Pannonian Plain is more widely used for roughly the same region though with a somewhat different sense, with only the Upland and lowland, lowlands, the plain that remained when the Pliocene Epoch ''Pannonian Sea'' dried out. It is a geomorphological subsystem of the Alpide belt, Alps-Himalaya system, specifically a sediment-filled back-arc basin which divergent boundary, spread apart during the Miocene. The plain or basin is diagonally bisected by the Transdanubian Mountains, separating the larger Great Hungarian Plain (including the Eastern Slovak Lowland) from the Little Hungarian Plain. It forms a topographically discrete unit set in the European landscape, surrounded by imposing geographic boundaries—the Carpathian Mountains and the Alps. The Rivers Danube and Tisza divide the basin roughly in half. It extends rough ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early Cretaceous
The Early Cretaceous ( geochronological name) or the Lower Cretaceous (chronostratigraphic name), is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 145 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 early Aptian Oceanic Anoxic Event 1a (OAE1a) was carbon isotope 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-Manihiki-Hikurangi large igneous province, emplaced in the South Pacific at c. 120 Ma, is by far the largest LIP in Earth's history. The Ontong Java Plateau today covers an area of 1,860,000 km2. In the Indian Ocean another LIP began to form at c. 120 Ma, the Kerguelen P ...

Barremian
The Barremian is an age in the geologic timescale (or a chronostratigraphic stage) between 129.4 ± 1.5 Ma (million years ago) and 121.4 ± 1.0 Ma). 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 '' Paradeshayesites oglanlensis''. Regional equivalents The Barremian falls in the Gallic epoch, a su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lignite
Lignite, 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. The combustion of lignite produces less heat for the amount of carbon dioxide and sulfur released than other ranks of coal. As a result, environmental advocates have characterized lignite as 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 which are left over in the coal fly ash produced from its combustion, further increasing health risks. Characteristics Lignite is brow ... [...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 (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe2O3), the aluminium clay mineral kaolinite (Al2Si2O5(OH)4) and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2). Bauxite appears dull in luster and is reddish-brown, white, or tan. In 1821, the French geologist Pierre Berthier discovered bauxite near the village of Les Baux in Provence, southern France. Formation Numerous classification schemes have been proposed for bauxite but, , there was no consensus. Vadász (1951) distinguished lateritic bauxites (silicate bauxites) from karst bauxite ores (carbonate bauxites): * The carbonate bauxites occur predominantly in Europe, Guyana, Suriname, and Jamaica above carbonate rocks (limestone and do ...

Apuseni Mountains
The Apuseni Mountains ( ro, Munții Apuseni, hu, Erdélyi-középhegység) is a mountain range in Transylvania, Romania, which belongs to the Western Romanian Carpathians, also called ''Occidentali'' in Romanian. Their name translates from Romanian as Mountains "of the sunset", i.e., "western". The highest peak is the Bihor Peak at . The Apuseni Mountains have about 400 caves. Geography The Apuseni Mountains do not present an uninterrupted chain of mountains, but possess many low and easy passes towards the Crișana and the Pannonian Plain. Going from south to north the principal groups are: the Munții Metaliferi ("Ore Mountains") with the basaltic masses of the Detunata () near Abrud; the Bihor Mountains, with numerous caverns, with the highest peak the Bihorul (); to the east of this group are the Muntele Mare (highest peak ), to the southwest of Cluj-Napoca; the northernmost chain is the Seș and Meseș Mountains.

Slovak Ore Mountains
The Slovak Ore Mountains ( sk, Slovenské rudohorie , hu, Gömör–Szepesi-érchegység, german: Slowakisches Erzgebirge or Zips-Gemer-Erzgebirge) are an extensive mountain range within the Carpathian Mountains, located mostly in Slovakia's Spiš and Gemer region, with a small part in northern Hungary. It is the largest mountain range in Slovakia. Geomorphologically, the Slovak Ore Mountains belong to the Inner Western Carpathians. The mountains are bordered by Zvolen in the west, Košice in the east, the rivers Hron and Hornád in the north, and the ''Juhoslovenská kotlina'' and Košice Basin (''Košická kotlina'') in the south. The region includes the Domica Cave (jaskyňa Domica), one of the largest caves in Europe, Zádiel canyon and Krásna Hôrka Castle. Subdivision Geomorphologically, the Slovak Ore Mountains are grouped within the Inner Western Carpathians. The mountains do not have a central ridge - they consist of several independent sections, geomorphological r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Treaty Of Trianon
The Treaty of Trianon (french: Traité de Trianon, hu, Trianoni békeszerződés, it, Trattato del Trianon) was prepared at the Paris Peace Conference (1919–1920), Paris Peace Conference and was signed in the Grand Trianon château in Versailles on 4 June 1920. It formally ended World War I between most of the Allies of World War I and the Kingdom of Hungary. French diplomats played the major role in designing the treaty, with a view to establishing a French-led coalition of the newly formed states. It regulated the status of the Kingdom of Hungary and defined its borders generally within the #Borders of Hungary, ceasefire lines established in November–December 1918 and left Hungary as a Landlocked country, landlocked state that included , 28% of the that had constituted the pre-war Lands of the Crown of Saint Stephen, Kingdom of Hungary (the Hungarian half of the Austria-Hungary, Austro-Hungarian monarchy). The truncated kingdom had a population of 7.6 million, 36% ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loránd Eötvös
Baron Loránd Eötvös de Vásárosnamény (or Loránd Eötvös, , '' hu, vásárosnaményi báró Eötvös Loránd Ágoston''; 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 peak (Cime 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. His mother was the Hungarian noble lad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austro-Hungarian Empire
Austria-Hungary, often referred to as the Austro-Hungarian Empire,, the Dual Monarchy, or Austria, was a constitutional monarchy and great power in Central Europe between 1867 and 1918. It was formed with the Austro-Hungarian Compromise of 1867 in the aftermath of the Austro-Prussian War and was dissolved shortly after its defeat in the First World War. Austria-Hungary was ruled by the House of Habsburg and constituted the last phase in the constitutional evolution of the Habsburg monarchy. It was a multinational state and one of Europe's major powers at the time. Austria-Hungary was geographically the second-largest country in Europe after the Russian Empire, at and the third-most populous (after Russia and the German Empire). The Empire built up the fourth-largest machine building industry in the world, after the United States, Germany and the United Kingdom. Austria-Hungary also became the world's third-largest manufacturer and exporter of electric home appliances, el ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
