Gorham's Cave
Gorham's Cave ( es, Cueva de Gorham, ) is a sea-level cave in the British overseas territory of Gibraltar. Though not a sea cave, it is often mistaken for one. Considered to be one of the last known habitations of the Neanderthals in Europe, the cave gives its name to the Gorham's Cave complex, which is a combination of four distinct caves of such importance that they are combined into a UNESCO World Heritage Site, the only one in Gibraltar. The three other caves are Vanguard Cave, Hyaena Cave, and Bennett's Cave.Gorham's Cave Complex, UNESCO tentative sites list Retrieved 4 August 2014 It is located at Governor's Beach on the southeastern face of the |
Alboran Sea
The Alboran Sea (from Arabic , ''al-Baḥrān'') is the westernmost portion of the Mediterranean Sea, lying between the Iberian Peninsula and the north of Africa (Spain on the north and Morocco and Algeria on the south). The Strait of Gibraltar, which lies at the west end of the Alboran Sea, connects the Mediterranean with the Atlantic Ocean. Geography Its average depth is and maximum depth is . The International Hydrographic Organization defines the limits of the Alboran Sea as follows: ''On the West.'' The Eastern limit of the Strait of Gibraltar: A line joining from tip ( Europa Point) of '' Cap Gibraltar'' in Europe to the tip of the '' Península de Almina'' of Ceuta in Africa (). ''On the East.'' A line joining from ''Cabo de Gata'' in Andalusia in Europe to ''Cap Fegalo'', near Oran, Algeria in Africa (). Several small islands dot the sea, including the eponymous Isla de Alborán. Most, even those close to the African shore, belong to Spain. Geology The Alboran doma ...

Royal Engineers
The Corps of Royal Engineers, usually called the Royal Engineers (RE), and commonly known as the ''Sappers'', is a corps of the British Army. It provides military engineering and other technical support to the British Armed Forces and is headed by the Chief Royal Engineer. The Regimental Headquarters and the Royal School of Military Engineering are in Chatham in Kent, England. The corps is divided into several regiments, barracked at various places in the United Kingdom and around the world. History The Royal Engineers trace their origins back to the military engineers brought to England by William the Conqueror, specifically Bishop Gundulf of Rochester Cathedral, and claim over 900 years of unbroken service to the crown. Engineers have always served in the armies of the Crown; however, the origins of the modern corps, along with those of the Royal Artillery, lie in the Board of Ordnance established in the 15th century. In Woolwich in 1716, the Board formed the Royal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Overburden
In mining, overburden (also called waste or spoil) is the material that lies above an area that lends itself to economical exploitation, such as the rock, soil, and ecosystem that lies above a coal seam or ore body. Overburden is distinct from tailings, the material that remains after economically valuable components have been extracted from the generally finely milled ore. Overburden is removed during surface mining, but is typically not contaminated with toxic components. Overburden may also be used to restore an exhausted mining site during reclamation. Interburden is material that lies between two areas of economic interest, such as the material separating coal seams within strata.Peng, Syd S. (1986) ''Coal Mine Ground Control'' (2nd edition), Wiley, New York, page 303, Analogous uses Overburden is also used for all soil and ancillary material above the bedrock horizon in a given area. By analogy, overburden is also used to describe the soil and other material that lies abo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archaeology
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes over 99% of the human past, from the Paleolithic unt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for lim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gibraltar Museum
The Gibraltar National Museum is a national museum of the history, culture and natural history of Gibraltar located within the city centre of the British overseas territory of Gibraltar. Founded in 1930 by the then Governor of Gibraltar, General Sir Alexander Godley, the museum houses an array of displays portraying The Rock's millennia-old history and the unique culture of its people. The museum also incorporates the remains of a 14th-century Moorish bathhouse. Its director since 1991 is Prof. Clive Finlayson. History Background There were several unsuccessful attempts to establish a museum in Gibraltar during the 19th century. Significant local finds could not be kept on The Rock because there was no museum, resulting in the first known adult Neanderthal skull (the so-called Gibraltar skull) went to the Natural History Museum in London. This was the second Neanderthal fossil to be found and was excavated in 1848 at Forbes' Quarry on the north face of the Rock of Gibra ...

George Palao
George L. Palao BEM (4 October 1940, Kensington, United Kingdom - 2009, Gibraltar) was a Gibraltarian historian and potholer and illustrator. He was particularly known for his excavations and finds in many caves of Gibraltar. Early years Born in Kensington, London on 4 October 1940, George Palao became part of an entire generation of Gibraltarians who were born away from the Rock after their parents were evacuated from Gibraltar along with most of the civilian population during World War II. When the war ended he and his family were repatriated to Gibraltar where he attended the Gibraltar Technical School and the Gibraltar Dockyard School. In 1958 Palao took up employment as a draghtsman for the Government of Gibraltar at their Public Works Department Drawing Office. He returned to London in 1970 to further his studies, enrolling on a two-year course at the South East London Technical College where he attended their Department of Building and Structural Engineering. He r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caving
Caving – also known as spelunking in the United States and Canada and potholing in the United Kingdom and Ireland – is the recreational pastime of exploring wild cave systems (as distinguished from show caves). In contrast, speleology is the scientific study of caves and the cave environment.Caving in New Zealand (from Te Ara: The Encyclopedia of New Zealand, Accessed 2012-11.) The challenges involved in caving vary according to the cave being visited; in addition to the total absence of light beyond the entrance, negotiating pitches, squeezes, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Historian
A historian is a person who studies and writes about the past and is regarded as an authority on it. Historians are concerned with the continuous, methodical narrative and research of past events as relating to the human race; as well as the study of all history in time. Some historians are recognized by publications or training and experience.Herman, A. M. (1998). Occupational outlook handbook: 1998–99 edition. Indianapolis: JIST Works. Page 525. "Historian" became a professional occupation in the late nineteenth century as research universities were emerging in Germany and elsewhere. Objectivity During the '' Irving v Penguin Books and Lipstadt'' trial, people became aware that the court needed to identify what was an "objective historian" in the same vein as the reasonable person, and reminiscent of the standard traditionally used in English law of " the man on the Clapham omnibus". This was necessary so that there would be a legal benchmark to compare and contrast the sch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gibraltarian People
The Gibraltarians (Spanish: ''gibraltareños'', colloquially: '' llanitos'') are an ethnic group native to Gibraltar, a British overseas territory located near the southernmost tip of the Iberian Peninsula at the entrance to the Mediterranean Sea. Origins Some Gibraltarians are a racial and cultural mixture of the many immigrants who came to the Rock of Gibraltar over 300 years. Following its capture by an Anglo-Dutch force in 1704, all but 70 of the existing inhabitants of Gibraltar elected to leave with many settling nearby. Since then, immigrants from Britain, Italy, Malta, Portugal, Morocco, Menorca, and India have settled at Gibraltar, as have Sephardic Jews from North Africa. Most Gibraltarian surnames are of Mediterranean or British extraction. The exact breakdown (including non-Gibraltarian British residents) according to the 1995 Census was as follows: Genoese and Catalans (who arrived in the fleet with Prince George of Hesse-Darmstadt) became the core of G ...

Lamp-black
Carbon black (subtypes are acetylene black, channel black, furnace black, lamp black and thermal black) is a material produced by the incomplete combustion of coal and coal tar, vegetable matter, or petroleum products, including fuel oil, fluid catalytic cracking tar, and ethylene cracking. Carbon black is a form of paracrystalline carbon that has a high surface-area-to-volume ratio, albeit lower than that of activated carbon. It is dissimilar to soot in its much higher surface-area-to-volume ratio and significantly lower (negligible and non-bioavailable) polycyclic aromatic hydrocarbon (PAH) content. However, carbon black can be used as a model compound for diesel soot to better understand how diesel soot behaves under various reaction conditions as carbon black and diesel soot have some similar properties such as particle sizes, densities, and copolymer adsorption abilities that contribute to them having similar behaviours under various reactions such as oxidation experiments ...
