Semna (Nubia) , Semna
The region of Semna is 15 miles south of Wadi Halfa and is situated where rocks cross the Nile narrowing its flow—the Semna Cataract. Semna was a fortified area established in the reign of Senusret I (1965–1920 BC) on the west bank of the Nile at the southern end of a series of Middle Kingdom fortresses founded during the Twelfth Dynasty of Egypt (1985–1795 BC) in the Second-Cataract area of Lower Nubia. There are three forts at Semna: Semna West (Semna Gharb), Semna East (Semna Sherq, also called Kummeh or Kumma), and Semna South (Semna Gubli). The forts to the east and west of the Semna Cataract are Semna East and West, respectively; Semna South is approximately one kilometer south of Semna West on the west bank of the Nile. The Semna gorge, at the southern edge of ancient Egypt, was the narrowest part of the Nile valley. It was here, at this strategic location, that the 12th Dynasty pharaohs built a cluster of four mud-brick fortresses: Semna, Kumma, Semna South an ...

Alluvial Soil
Alluvium (from Latin ''alluvius'', from ''alluere'' 'to wash against') is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings. Alluvium is also sometimes called alluvial deposit. Alluvium is typically geologically young and is not consolidated into solid rock. Sediments deposited underwater, in seas, estuaries, lakes, or ponds, are not described as alluvium. Floodplain alluvium can be highly fertile, and supported some of the earliest human civilizations. Definitions The present consensus is that "alluvium" refers to loose sediments of all types deposited by running water in floodplains or in alluvial fans or related landforms. However, the meaning of the term has varied considerably since it was first defined in the French dictionary of Antoine Furetière, posthumously published in 1690. Drawing upon concepts from Roman law, Furetière defined ''alluvion'' (the Fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Igneous Rock
Igneous rock (derived from the Latin word ''ignis'' meaning fire), or magmatic rock, is one of the three main The three types of rocks, rock types, the others being Sedimentary rock, sedimentary and metamorphic rock, metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava. The magma can be derived from Partial melting, partial melts of existing rocks in either a Terrestrial planet, planet's mantle (geology), mantle or crust (geology), 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 (geology), extrusive rocks. Igneous rock may form with crystallization to form granular, crystalline rocks, or without crystallization to form Volcanic glass, natural glasses. Igneous rocks occur in a wide range of geological settings: shields, platforms ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedimentary Rock
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus (organic matter). The geological detritus originated from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or mass movement, which are called agents of denudation. Biological detritus was formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur as dissolved minerals precipitate from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precambrian
The Precambrian (or Pre-Cambrian, sometimes abbreviated pꞒ, or Cryptozoic) is the earliest part of Earth's history, set before the current Phanerozoic Eon. The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic Eon, which is named after Cambria, the Latinised name for Wales, where rocks from this age were first studied. The Precambrian accounts for 88% of the Earth's geologic time. The Precambrian is an informal unit of geologic time, subdivided into three eons ( Hadean, Archean, Proterozoic) of the geologic time scale. It spans from the formation of Earth about 4.6 billion years ago ( Ga) to the beginning of the Cambrian Period, about million years ago ( Ma), when hard-shelled creatures first appeared in abundance. Overview Relatively little is known about the Precambrian, despite it making up roughly seven-eighths of the Earth's history, and what is known has largely been discovered from the 1960s onwards. The Precambrian fossil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Batn-El-Hajar
Batn-El-Hajar or ''Belly of Stones'' is a reach of approximately 160 km in length stretching from the Dal Cataract of the Nile downriver to the now under Lake Nubia submerged Second Cataract in present-day Sudan. History ''Batn-El-Hajar'' is a barren and granite-rich landscape limiting arable soil and, thus, sparsely inhabited. It was the traditional border between Upper Nubia and Lower Nubia. In this area are a number of important A-Group The A-Group culture was an ancient culture that flourished between the First and Second Cataracts of the Nile in Nubia.

University Of Chicago Oriental Institute
The Oriental Institute (OI), established in 1919, is the University of Chicago's interdisciplinary research center for ancient Near Eastern ("Orient") studies and archaeology museum. It was founded for the university by professor James Henry Breasted with funds donated by John D. Rockefeller, Jr. It conducts research on ancient civilizations throughout the Near East, including at its facility, Chicago House, in Luxor, Egypt. The institute publicly exhibits an extensive collection of artifacts related to ancient civilizations at its on-campus building in Hyde Park, Chicago. According to anthropologist William Parkinson of the Field Museum, the OI's highly focused "near Eastern, or southwest Asian and Egyptian" collection is one of the finest in the world. History In the early 20th century, James Henry Breasted built up the collection of the university's Haskell Oriental Museum, which he oversaw along with his field work, and teaching duties. He dreamed, however, of establishi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
