Sindh
Sindh (; ; ur, , ; historically romanized as Sind) is one of the four provinces of Pakistan. Located in the southeastern region of the country, Sindh is the third-largest province of Pakistan by land area and the second-largest province by population after Punjab. It shares land borders with the Pakistani provinces of Balochistan to the west and north-west and Punjab to the north. It shares International border with the Indian states of Gujarat and Rajasthan to the east; it is also bounded by the Arabian Sea to the south. Sindh's landscape consists mostly of alluvial plains flanking the Indus River, the Thar Desert in the eastern portion of the province along the international border with India, and the Kirthar Mountains in the western portion of the province. The economy of Sindh is the second-largest in Pakistan after the province of Punjab; its provincial capital of Karachi is the most populous city in the country as well as its main financial hub. Sindh is home ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sedimentary
Sedimentary rocks are types of rock (geology), rock that are formed by the accumulation or deposition of mineral or organic matter, organic particles at Earth#Surface, Earth's surface, followed by cementation (geology), 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 detritus (geology), geological detritus (minerals) or detritus, 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 wasting, 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 ...

Middle Eocene
The Eocene ( ) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope 13C in the atmosphere was exceptionally low in comparison with the more common isotope 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and end of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early Oligocene
The Rupelian is, in the geologic timescale, the older of two ages or the lower of two stages of the Oligocene Epoch/Series. It spans the time between . It is preceded by the Priabonian Stage (part of the Eocene) and is followed by the Chattian Stage. Name The stage is named after the small river Rupel in Belgium, a tributary to the Scheldt. The Belgian Rupel Group derives its name from the same source. The name Rupelian was introduced in scientific literature by Belgian geologist André Hubert Dumont in 1850. The separation between the group and the stage was made in the second half of the 20th century, when stratigraphers saw the need to distinguish between lithostratigraphic and chronostratigraphic names. Stratigraphic definition The base of the Rupelian Stage (which is also the base of the Oligocene Series) is at the extinction of the foraminiferan genus ''Hantkenina''. An official GSSP for the base of the Rupelian has been assigned in 1992 (Massignano, Italy). The transi ... [...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 limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rohri
Rohri ( Sindhi: روهڙي; ur, ) is a city of Sukkur District, Sindh province, Pakistan. It is located on the east bank of the Indus River, located directly across from Sukkur, the third largest city in Sindh. Rohri town is the administrative headquarters of Rohri Taluka, a tehsil of Sukkur District with which it forms a metropolitan area. History Rohri is west of the ancient city of Aror. Roruka, as capital of the Sauvira Kingdom, is mentioned as an important trading center in early Buddhist literature. Little is known about the city's history prior to the Arab invasion in the eighth century, but Aror was the capital of the A-Ror Dynasty, which was followed by Rai Dynasty and then the Brahman Dynasty that once ruled northern Sindh. In 711 CE, Aror was captured by the army of Muslim general Muhammad bin Qasim. In 962 CE, a massive earthquake struck the region, causing the course of the Indus River to shift. Aror was re-founded as Rohri afterwards. Rohri served as a busy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indus River
The Indus ( ) is a transboundary river of Asia and a trans-Himalayan river of South and Central Asia. The river rises in mountain springs northeast of Mount Kailash in Western Tibet, flows northwest through the disputed region of Kashmir, Quote: "Kashmir, region of the northwestern Indian subcontinent. It is bounded by the Uygur Autonomous Region of Xinjiang to the northeast and the Tibet Autonomous Region to the east (both parts of China), by the Indian states of Himachal Pradesh and Punjab to the south, by Pakistan to the west, and by Afghanistan to the northwest. The northern and western portions are administered by Pakistan and comprise three areas: Azad Kashmir, Gilgit, and Baltistan, ... The southern and southeastern portions constitute the Indian state of Jammu and Kashmir. The Indian- and Pakistani-administered portions are divided by a "line of control" agreed to in 1972, although neither country recognizes it as an international boundary. In addition, China became ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nara Canal
The Nara Canal is a deepened delta channel of the Indus River in Sindh province, Pakistan. It was built as an excavated channel stemming off the left bank of the Indus River to join the course of the old Nara River, a tributary c.q. paleochannel of the Indus which received water from the Ghaggar-Hakra until the Hakra dried-up, early 2nd millennium BCE. Geography The canal runs from above the Sukkur Barrage through the districts of Khairpur, Sanghar, Mirpurkhas and Tharparkar to the Jamrao Canal. The Nara is the longest canal in Pakistan, running for about . It has a designed capacity of , but actually discharges . About of land are irrigated by this canal. Within the Khairpur District, the canal and its associated wetlands were made into the Nara Game Reserve in 1972. Construction of the canal Before the construction of the Nara canal, the Indus River used to overflow in Bahawalpur and Sind Province above Rohri and the spillovers used to enter the Nara River. Bunds were constr ... [...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 until the adven ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flint
Flint, occasionally flintstone, is a sedimentary cryptocrystalline form of the mineral quartz, categorized as the variety of chert that occurs in chalk or marly limestone. Flint was widely used historically to make stone tools and start fires. It occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones.''The Flints from Portsdown Hill'' Inside the nodule, flint is usually dark grey, black, green, white or brown in colour, and often has a glassy or waxy appearance. A thin layer on the outside of the nodules is usually different in colour, typically white and rough in texture. The nodules can often be found along s and |
Paleolithic
The Paleolithic or Palaeolithic (), also called the Old Stone Age (from Greek: παλαιός ''palaios'', "old" and λίθος ''lithos'', "stone"), is a period in human prehistory that is distinguished by the original development of stone tools, and which represents almost the entire period of human prehistoric technology. It extends from the earliest known use of stone tools by hominins, 3.3 million years ago, to the end of the Pleistocene, 11,650 cal BP. The Paleolithic Age in Europe preceded the Mesolithic Age, although the date of the transition varies geographically by several thousand years. During the Paleolithic Age, hominins grouped together in small societies such as bands and subsisted by gathering plants, fishing, and hunting or scavenging wild animals. The Paleolithic Age is characterized by the use of knapped stone tools, although at the time humans also used wood and bone tools. Other organic commodities were adapted for use as tools, includ ...
