Ganj Par
Ganj Par () is a Lower Paleolithic site located in the Gilan province in northern Iran. Located on an old western terrace of the Sefīd-Rūd River, the site was discovered by a team of archaeologists from the Center for Paleolithic Research of the National Museum of Iran in 2002. The Lower Paleolithic cave site of Darband Cave is located east of Ganj Par. Artefacts About 150 stone artifacts — handaxes, cleavers, a pick, choppers, and smaller flake tools — made of limestone, igneous rocks, and sandstone have been found at the site. There are some similarities between these Acheulian stone tools with those found in Caucasus region. The Discovery of Ganj Par thus indicates that Iran Iran, officially the Islamic Republic of Iran (IRI) and also known as Persia, is a country in West Asia. It borders Iraq to the west, Turkey, Azerbaijan, and Armenia to the northwest, the Caspian Sea to the north, Turkmenistan to the nort ... is part of the Acheulian terr ...

Lithic Flake
In archaeology, a lithic flake is a "portion of rock (geology), rock removed from an objective piece by percussion or pressure,"Andrefsky, W. (2005) ''Lithics: Macroscopic Approaches to Analysis''. 2d Ed. Cambridge, Cambridge University Press and may also be referred to as simply a ''flake'', or collectively as debitage. The objective piece, or the rock being reduced by the removal of flakes, is known as a lithic core, core.Andrefsky, W. (2005) ''Lithics: Macroscopic Approaches to Analysis''. 2d Ed. Cambridge, Cambridge University Press Once the proper tool stone has been selected, a percussor or pressure flaker (e.g., an antler Tine (structural), tine) is used to direct a sharp blow, or apply sufficient force, respectively, to the surface of the stone, often on the edge of the piece. The energy of this blow propagates through the material, often (termination type, but not always) producing a Hertzian cone of force which causes the rock to fracture in a controllable fashion.

Caucasus
The Caucasus () or Caucasia (), is a region spanning Eastern Europe and Western Asia. It is situated between the Black Sea and the Caspian Sea, comprising parts of Southern Russia, Georgia, Armenia, and Azerbaijan. The Caucasus Mountains, including the Greater Caucasus range, have conventionally been considered as a natural barrier between Europe and Asia, bisecting the Eurasian landmass. Mount Elbrus, Europe's highest mountain, is situated in the Western Caucasus area of Russia. On the southern side, the Lesser Caucasus includes the Javakheti Plateau and the Armenian highlands. The Caucasus is divided into the North Caucasus and South Caucasus, although the Western Caucasus also exists as a distinct geographic space within the North Caucasus. The Greater Caucasus mountain range in the north is mostly shared by Russia and Georgia as well as the northernmost parts of Azerbaijan. The Lesser Caucasus mountain range in the south is mostly located on the territory of sout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acheulian
Acheulean (; also Acheulian and Mode II), from the French after the type site of Saint-Acheul, is an archaeological industry of stone tool manufacture characterized by the distinctive oval and pear-shaped "hand axes" associated with ''Homo erectus'' and derived species such as ''Homo heidelbergensis''. Acheulean tools were produced during the Lower Palaeolithic era across Africa and much of West Asia, South Asia, East Asia and Europe, and are typically found with ''Homo erectus'' remains. It is thought that Acheulean technologies first developed about 2 million years ago, derived from the more primitive Oldowan technology associated with ''Homo habilis''. The Acheulean includes at least the early part of the Middle Paleolithic. Its end is not well defined; if Sangoan (also known as Epi-Acheulean) is included, it may be taken to last until as late as 130,000 years ago. In Europe and Western Asia, early Neanderthals adopted Acheulean technology, transitioning to Moust ... [...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] |
Igneous Rock
Igneous rock ( ), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rocks are formed through the cooling and solidification of magma or lava. The magma can be derived from partial melts of existing rocks in either a planet's mantle or crust. Typically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Solidification into rock occurs either below the surface as intrusive rocks or on the surface as extrusive rocks. Igneous rock may form with crystallization to form granular, crystalline rocks, or without crystallization to form natural glasses. Igneous rocks occur in a wide range of geological settings: shields, platforms, orogens, basins, large igneous provinces, extended crust and oceanic crust. Geological significance Igneous and metamorphic rocks make up 90–95% of the top of the Earth's crust by volume. Igneous rock ...

Limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science), crystal forms of calcium carbonate . Limestone forms when these minerals Precipitation (chemistry), 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 (rock), dolomite, a closely related rock, which contains a high percentage of the mineral Dolomite (mine ...

Cleaver
A cleaver is a large knife that varies in its shape but usually resembles a rectangular-bladed tomahawk. It is largely used as a kitchen knife, kitchen or butcher knife and is mostly intended for splitting up large pieces of soft bones and slashing through thick pieces of meat. The knife's broad side can also be used for crushing in outline of food preparation, food preparation (such as garlic) and can also be used to scoop up chopped items. Cleaver (tool), Tools described as cleavers have been in use since the Acheulean period. "Cleaver" was commonly spelled ''clever'' in the late 17th century. Design In contrast to other kitchen knives, the cleaver has an especially toughness, tough edge meant to withstand repeated blows directly into thick meat, dense cartilage, bone, and the cutting board below. This resilience is accomplished by using a softer, tougher steel and a thicker blade, because a harder steel or thinner blade might fracture or Buckling, buckle under hard use. I ...

Lower Paleolithic
The Lower Paleolithic (or Lower Palaeolithic) is the earliest subdivision of the Paleolithic or Old Stone Age. It spans the time from around 3.3 million years ago when the first evidence for stone tool production and use by hominins appears in the current archaeological record, until around 300,000 years ago, spanning the Oldowan ("mode 1") and Acheulean ("mode 2") lithics industries. In African archaeology, the time period roughly corresponds to the Early Stone Age, the earliest finds dating back to 3.3 million years ago, with Lomekwian stone tool technology, spanning Mode 1 stone tool technology, which begins roughly 2.6 million years ago and ends between 400,000 and 250,000 years ago, with Mode 2 technology. The Middle Paleolithic followed the Lower Paleolithic and recorded the appearance of the more advanced prepared-core tool-making technologies such as the Mousterian. Whether the earliest control of fire by hominins dates to the Lower or to the Middle Paleolithic rem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handaxe
A hand axe (or handaxe or Acheulean hand axe) is a prehistoric stone tool with two faces that is the longest-used tool in human history. It is made from stone, usually flint or chert that has been "reduced" and shaped from a larger piece by knapping, or hitting against another stone. They are characteristic of the lower Acheulean and middle Palaeolithic (Mousterian) periods, roughly 1.6 million years ago to about 100,000 years ago, and used by ''Homo erectus'' and other early humans, but rarely by ''Homo sapiens''. Their technical name (biface) comes from the fact that the archetypical model is a generally bifacial (with two wide sides or faces) and almond-shaped (amygdaloidal) lithic flake. Hand axes tend to be symmetrical along their longitudinal axis and formed by pressure or percussion. The most common hand axes have a pointed end and rounded base, which gives them their characteristic almond shape, and both faces have been knapped to remove the natural cortex, at least pa ...

Darband Cave
Darband Cave is a Lower Paleolithic site in the Gilan Province in northern Iran, located on the north side of a deep tributary canyon of the Siahrud River, a tributary of the Sefīd-Rūd River that flows into the Caspian Sea. The cave contains evidence of the earliest prehistoric human cave occupation during the Lower Paleolithic in Iran. Stone artifacts and animal fossils were discovered by a group of Iranian archaeologists of the ''Department of Paleolithic'' of the National Museum of Iran and ICHTO of Gilan. The site dates back to the late Middle Pleistocene period. The site was excavated by a team under the direction of Fereidoun Biglari in 2012 Biglari, F., V. Jahani, M. Mashkour, and S.
