Reinout Willem Van Bemmelen
Reinout Willem van Bemmelen, also known as Rein van Bemmelen, (14 April 1904 Batavia, Dutch East Indies – 19 November 1983 Unterpirkach, Austria) was a Dutch geologist whose interests were structural geology, economic geology and volcanology. He is known for his work on these subjects and the geology of Indonesia. Biography Rein van Bemmelen was born in Batavia and spent his youth in the Dutch East Indies, where his father Willem van Bemmelen was the director of the Magnetic, Meteorological and Seismological Observatory. From 1920 to 1927 he studied mining engineering at Delft University in the Netherlands. Among his teachers were H.A. Brouwer and G.A.F. Molengraaff. Van Bemmelen became PhD in 1927 with a study on the geology of the Cordillera Bética. He took courses in volcanology at Naples and then worked with the geological survey in the Dutch East Indies, where he mapped parts of Java and Sumatra. From 1933 to 1935 he studied pedology at the Technical University of Vi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Batavia, Dutch East Indies
Batavia was the capital of the Dutch East Indies. The area corresponds to present-day Jakarta, Indonesia. Batavia can refer to the city proper or its suburbs and hinterland, the Ommelanden, which included the much-larger area of the Residency of Batavia in the present-day Indonesian provinces of Jakarta, Banten and West Java. The founding of Batavia by the Dutch in 1619, on the site of the ruins of Jayakarta, led to the establishment of a Dutch colony; Batavia became the center of the Dutch East India Company's trading network in Asia. Monopolies on local produce were augmented by non-indigenous cash crops. To safeguard their commercial interests, the company and the colonial administration absorbed surrounding territory. Batavia is on the north coast of Java, in a sheltered bay, on a land of marshland and hills crisscrossed with canals. The city had two centers: Oud Batavia (the oldest part of the city) and the relatively-newer city, on higher ground to the south. It was ...

Cordillera Bética
The Baetic System or Betic System ( es, Sistema Bético) is one of the main systems of mountain ranges in Spain. Located in the southern and eastern Iberian Peninsula, it is also known as the Cordilleras Béticas (Baetic Mountain Ranges) or Baetic Mountains. The name of the mountain system derives from the ancient Roman region of Baetica, one of the Imperial Roman provinces of ancient Hispania. Geography The Baetic System is made up of multiple mountain ranges that reach from western Andalusia to the Region of Murcia, southern Castile-La Mancha and the Land of Valencia. To the north, the Baetic Ranges are separated from the Meseta Central and the Sierra Morena by the basin of the Guadalquivir. The Iberian System rises north of the eastern part of the Prebaetic System, the northernmost prolongation of the Baetic System. Generally the mountain ranges that are part of this system are aligned in a southwest-northeast direction. The most well-known range of the Baetic System is the ...

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] |

Mount Merapi
Mount Merapi, ''Gunung Merapi'' (literally Fire Mountain in Indonesian and Javanese), is an active stratovolcano located on the border between the province of Central Java and the Special Region of Yogyakarta, Indonesia. It is the most active volcano in Indonesia and has erupted regularly since 1548. It is located approximately north of Yogyakarta city which has a population of 2.4 million, and thousands of people live on the flanks of the volcano, with villages as high as above sea level. Smoke can often be seen emerging from the mountaintop, and several eruptions have caused fatalities. A pyroclastic flow from a large explosion killed 27 people on 22 November 1994, mostly in the town of Muntilan, west of the volcano. Another large eruption occurred in 2006, shortly before the Yogyakarta earthquake. In light of the hazards that Merapi poses to populated areas, it was designated as one of the Decade Volcanoes. On the afternoon of 25 October 2010, Merapi erupted on its sout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tectonics
Tectonics (; ) are the processes that control the structure and properties of the Earth's crust and its evolution through time. These include the processes of mountain building, the growth and behavior of the strong, old cores of continents known as cratons, and the ways in which the relatively rigid plates that constitute the Earth's outer shell interact with each other. Tectonics also provide a framework for understanding the earthquake and volcanic belts that directly affect much of the global population. Tectonic studies are important as guides for economic geologists searching for fossil fuels and ore deposits of metallic and nonmetallic resources. An understanding of tectonic principles is essential to geomorphologists to explain erosion patterns and other Earth surface features. Main types of tectonic regime Extensional tectonics Extensional tectonics is associated with the stretching and thinning of the crust or the lithosphere. This type of tectonics is found ...

Pyroclastic Rock
Pyroclastic rocks (derived from the el, πῦρ, links=no, meaning fire; and , meaning broken) are clastic rocks composed of rock fragments produced and ejected by explosive volcanic eruptions. The individual rock fragments are known as pyroclasts. Pyroclastic rocks are a type of volcaniclastic deposit, which are deposits made predominantly of volcanic particles. 'Phreatic' pyroclastic deposits are a variety of pyroclastic rock that forms from volcanic steam explosions and they are entirely made of accidental clasts. 'Phreatomagmatic' pyroclastic deposits are formed from explosive interaction of magma with groundwater. Unconsolidated accumulations of pyroclasts are described as tephra. Tephra may become lithified to a pyroclastic rock by cementation or chemical reactions as the result of the passage of hot gases (fumarolic alteration) or groundwater (e.g. hydrothermal alteration and diagenesis) and burial, or, if it is emplaced at temperatures so hot that the soft glassy pyrocl ...

Magma
Magma () is the molten or semi-molten natural material from which all igneous rocks are formed. Magma is found beneath the surface of the Earth, and evidence of magmatism has also been discovered on other terrestrial planets and some natural satellites. Besides molten rock, magma may also contain suspended crystals and gas bubbles. Magma is produced by melting of the mantle or the crust in various tectonic settings, which on Earth include subduction zones, continental rift zones, mid-ocean ridges and hotspots. Mantle and crustal melts migrate upwards through the crust where they are thought to be stored in magma chambers or trans-crustal crystal-rich mush zones. During magma's storage in the crust, its composition may be modified by fractional crystallization, contamination with crustal melts, magma mixing, and degassing. Following its ascent through the crust, magma may feed a volcano and be extruded as lava, or it may solidify underground to form an intrusion, such as a ...

Pedology (soil Study)
Pedology (from Greek: πέδον, ''pedon'', "soil"; and λόγος, ''logos'', "study") is a discipline within soil science which focuses on understanding and characterizing soil formation, evolution, and the theoretical frameworks for modeling soil bodies, often in the context of the natural environment. Pedology is often seen as one of two main branches of soil inquiry, the other being edaphology which is traditionally more agronomically oriented and focuses on how soil properties influence plant communities (natural or cultivated). In studying the fundamental phenomenology of soils, e.g. soil formation (aka pedogenesis), pedologists pay particular attention to observing soil morphology and the geographic distributions of soils, and the placement of soil bodies into larger temporal and spatial contexts. In so doing, pedologists develop systems of soil classification, soil maps, and theories for characterizing temporal and spatial interrelations among soils . There are a few note ...
