Wolf Cave
Susiluola (, 'Wolf Cave') is a crack in the mountain () at the border of and municipalities in Finland. The upper part of the crack has been packed with soil, forming a cave. In 1996, some objects were found in the cave that brought about speculations that it could have been inhabited in the Paleolithic, between 120,000 and 130,000 years ago. These objects, if authentic, would be the only known Neanderthal artifacts in the Nordic countries. Excavation history In 1996, plans were made to empty the cave of soil and turn it into a tourist attraction, but during the process, stone objects that might have been created by humans were found and the work to empty the cave was halted. In 1997, an excavation of the cave was begun as a collaboration between the National Board of Antiquities, the Geological Survey of Finland, the Department of Geology of the University of Helsinki, and the Finnish Museum of Natural History. This excavation lasted until 2000, and was focused on determi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quartz
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The Atom, atoms are linked in a continuous framework of SiO4 silicon–oxygen Tetrahedral molecular geometry, tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of Silicon dioxide, SiO2. Quartz is, therefore, classified structurally as a Silicate mineral#Tectosilicates, framework silicate mineral and compositionally as an oxide mineral. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation from α-quartz to β-quartz takes place abruptly at . Since the transformation is accompanied by a significant change in volume, it can easily induce microfracturing of ceramics or rocks passing through this temperature threshold. There are many different varieties of quartz, several of which are classifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History Of Ostrobothnia (administrative Region)
Ostrobothnia (; ) is a historical province comprising a large portion of western and northern Finland. Before the Treaty of Fredrikshamn in 1809, Ostrobothnia was part of Sweden. It is bounded by Karelia, Savonia (historical province), Savo, Tavastia (historical province), Tavastia (Häme) and Satakunta in the south, the Bothnian Sea, Bothnian Bay and Swedish Norrbotten in the west, Lapland in the north and Russia in the east. Etymology The word ''botten'' derives from Old Norse ''botn'', meaning 'bay'. It is Latinized as ''Bothnia''. The Finnish word ''pohja'' means either "north" or "bottom", and ''maa'' is "land". There are two possible explanations for the dual meaning of ''pohja''. The first is based on the ancient Scandinavian belief that the north was the bottom of the world, where the Sun disappeared each night. The second explanation points to the fact that houses were constructed with their backs to the north, the coldest direction, which may have given rise to ...

Landforms Of Ostrobothnia (administrative Region)
A landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great oceanic basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type. Gross physical features or landforms include intuitive elements such as berms, cliffs, hills, mounds, peninsulas, ridges, rivers, valleys, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodi ...

Archaeological Sites In Finland
Archaeology or archeology is the 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. The discipline involves surveying, excavation, and eventually analysis of data collected, to learn more about the past. In broad scope, archaeology relies on cross-disciplinary research. 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 learnin ...

Caves Of Finland
Caves or caverns are natural voids under the Earth's surface. Caves often form by the weathering of rock and often extend deep underground. Exogene caves are smaller openings that extend a relatively short distance underground (such as rock shelters). Caves which extend further underground than the opening is wide are called endogene caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorganisms, pressure, and atmospheric influences. Isotopic dating techniques can be applied to cave sediments, to determine the time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turun Sanomat
is the leading regional newspaper of the region of Southwest Finland. It is published in the region's capital, Turku and the third most widely read morning newspaper in Finland after ''Helsingin Sanomat'' and ''Aamulehti''. History and profile ''Turun Sanomat'' was launched in 1905 as supporter of the liberal Young Finnish Party. The founder of the paper was Antti Mikkola, a politician and a journalist. It was subsequently owned and managed by Arvo Ketonen and, following his death in 1948, by his widow Irja Ketonen. ''Turun Sanomat'' was one of the conservative papers in the Cold War period. During this period it was one of the Finnish newspapers which were accused by the Soviet Union of being the instrument of US propaganda, and the Soviet Embassy in Helsinki frequently protested the editors of the paper. The paper has been officially politically independent and non-aligned since 1961. It is owned by TS Group. The paper is headquartered in Turku. It is published by TS-Yh ...

Ice Age
An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages, and greenhouse periods during which there are no glaciers on the planet. Earth is currently in the ice age called Quaternary glaciation. Individual pulses of cold climate within an ice age are termed '' glacial periods'' (''glacials, glaciations, glacial stages, stadials, stades'', or colloquially, ''ice ages''), and intermittent warm periods within an ice age are called '' interglacials'' or ''interstadials''. In glaciology, the term ''ice age'' is defined by the presence of extensive ice sheets in the northern and southern hemispheres. By this definition, the current Holocene epoch is an interglacial period of an ice age. The accumulation of anthropogenic greenhouse gases is projected to delay the next glacial period.

Clactonian
The Clactonian is the name given by archaeologists to an industry of European flint tool manufacture that dates to the early part of the Hoxnian Interglacial (corresponding to the global Marine Isotope Stage 11 and the continental Holstein Interglacial) around 424–415,000 years ago. Clactonian tools were made by ''Homo heidelbergensis''. The Clactonian is primarily distinguished from the (globally) contemporaneous Acheulean industry by its lack of use of handaxe tools. It is named after finds made by Samuel Hazzledine Warren in a palaeochannel at Clacton-on-Sea in the English county of Essex in 1911. The artefacts found there included flint chopping tools, flint flakes and the tip of a worked wooden shaft, the Clacton Spear. Further examples of the tools have been found at sites including Barnfield Pit and Rickson's Pit, near Swanscombe in Kent and Barnham in Suffolk; similar industries have been identified across Northern Europe. The Clactonian industry involved stri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middle Paleolithic
The Middle Paleolithic (or Middle Palaeolithic) is the second subdivision of the Paleolithic or Old Stone Age as it is understood in Europe, Africa and Asia. The term Middle Stone Age is used as an equivalent or a synonym for the Middle Paleolithic in African archeology. The Middle Paleolithic broadly spanned from 300,000 to 50,000 years ago. There are considerable dating differences between regions. The Middle Paleolithic was succeeded by the Upper Paleolithic subdivision which first began between 50,000 and 40,000 years ago. Pettit and White date the Early Middle Paleolithic in Great Britain to about 325,000 to 180,000 years ago (late Marine Isotope Stage 9 to late Marine Isotope Stage 7), and the Late Middle Paleolithic as about 60,000 to 35,000 years ago. The Middle Paleolithic was in the geological Chibanian (Middle Pleistocene) and Late Pleistocene ages. According to the theory of the recent African origin of modern humans, anatomically modern humans began migrat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sandstone
Sandstone is a Clastic rock#Sedimentary clastic rocks, clastic sedimentary rock composed mainly of grain size, sand-sized (0.0625 to 2 mm) silicate mineral, silicate grains, Cementation (geology), cemented together by another mineral. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar, because they are the most resistant minerals to the weathering processes at the Earth's surface. Like uncemented sand, sandstone may be imparted any color by impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Because sandstone beds can form highly visible cliffs and other topography, topographic features, certain colors of sandstone have become strongly identified with certain regions, such as the red rock deserts of Arches National Park and other areas of the Southwestern United States, American Southwest. Rock formations composed of sandstone usually allow the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
