Quri Qala Cave
Quri Qala Cave or QuraQala (Kurdish languages, Kurdish: Şikefta QureQela, ئەشکەوتی قوڕەقەڵا Persian: غار قوری قلعه) is a cave located northwest of Ravansar, Iran, and is one of the longest caves in western Asia. First explored in the 1950s, in 1989 it was further opened by an Iranian team. It contains three main chambers, with calcite crystals, stalactites and waterfalls. It is known for its colony of Mouse-eared bat,Iranian Students' News Agency (ISNA): ''Glorious Quri Qal-e Cave'', published on 7 August 2018 visited on 30 June 2023. and for a number of archaeological finds, including silver vessels dating to the late Sassanian period. These silver vessels are related to the late Sasanian period and decorated with a hawk catching a bird, birds, l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cave Of Ghori Ghal
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] |
Kurdish Languages
Kurdish (, , ) is a Northwestern Iranian language or group of languages spoken by Kurds in the region of Kurdistan, namely in southeast Turkey, northern Iraq, northwest Iran, and northern Syria. It is also spoken in northeast Iran, as well as in certain areas of Armenia and Azerbaijan. Kurdish varieties constitute a dialect continuum, with some mutually unintelligible varieties, and collectively have 26 million native speakers. The main varieties of Kurdish are Kurmanji, Sorani, and Southern Kurdish (). The majority of the Kurds speak Kurmanji, and most Kurdish texts are written in Kurmanji and Sorani. Kurmanji is written in the Hawar alphabet, a derivation of the Latin script, and Sorani is written in the Sorani alphabet, a derivation of the Arabic script. A separate group of non-Kurdish Northwestern Iranian languages, the Zaza–Gorani languages, are also spoken by several million ethnic Kurds.Kaya, Mehmet.

Ravansar
Ravansar () is a city in the Central District of Ravansar County, Kermanshah province, Iran, serving as capital of both the county and the district. Archaeology and history Archaeology Ravansar has important prehistoric and historical sites, and in this respect, it has a special place in the archaeology of the west of Iran. The earliest evidence of human habitation around Ravansar extends back to the Middle Paleolithic that continues to the end of the glacial period (at least from about 50,000 years to 12,000 years ago), whose remains were found in the caves of the Kulian and Jawri, as well as the Garab River (Awi Kher). Another important discovery in the region is an elephant molar tooth that dates back to the Pleistocene era and has been discovered near Ravansar. Other important archaeological site is the Musaei mound and its two nearby smaller mounds, it has been inhabited since the end of the Neolithic period (about 8,000 years ago). In the course of the Assyrian camp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calcite
Calcite is a Carbonate minerals, carbonate mineral and the most stable Polymorphism (materials science), polymorph of calcium carbonate (CaCO3). It is a very common mineral, particularly as a component of limestone. Calcite defines hardness 3 on the Mohs scale of mineral hardness, based on Scratch hardness, scratch hardness comparison. Large calcite crystals are used in optical equipment, and limestone composed mostly of calcite has numerous uses. Other polymorphs of calcium carbonate are the minerals aragonite and vaterite. Aragonite will change to calcite over timescales of days or less at temperatures exceeding 300 °C, and vaterite is even less stable. Etymology Calcite is derived from the German , a term from the 19th century that came from the Latin word for Lime (material), lime, (genitive ) with the suffix ''-ite'' used to name minerals. It is thus a Doublet (linguistics), doublet of the word ''wikt:chalk, chalk''. When applied by archaeology, archaeologists and ...

Stalactite
A stalactite (, ; , ) is a mineral formation that hangs from the ceiling of caves, hot springs, or man-made structures such as bridges and mines. Any material that is soluble and that can be deposited as a colloid, or is in suspension (chemistry), suspension, or is capable of being melting, melted, may form a stalactite. Stalactites may be composed of lava, minerals, mud, peat, pitch (resin), pitch, sand, Geyserite, sinter, and amberat (crystallized urine of pack rats). A stalactite is not necessarily a speleothem, though speleothems are the most common form of stalactite because of the abundance of limestone caves. The corresponding formation on the floor of the cave is known as a stalagmite. Formation and type Limestone stalactites The most common stalactites are speleothems, which occur in limestone caves. They form through Deposition (geology), deposition of calcium carbonate and other minerals, which is precipitated from mineralized water Solution (chemistry), solutio ...

Mouse-eared Bat
The mouse-eared bats or myotises are a diverse and widespread genus (''Myotis'') of bats within the family Vespertilionidae. The noun "''myotis''" itself is a Neo-Latin construction, from the Greek language, Greek "''muós'' (meaning "mouse") and "''oûs''" (meaning ear), literally translating to "mouse-eared". Relationships ''Myotis'' has historically been included in the subfamily Vespertilioninae, but was classified in its own subfamily, Myotinae, by Nancy Simmons in 1998. In her 2005 classification in ''Mammal Species of the World'', Simmons listed the genera ''Cistugo'' and ''Lasionycteris'' in the Myotinae in addition to ''Myotis'' itself.Simmons, 2005, p. 499 However, molecular data indicate that ''Cistugo'' is distantly related to all other Vespertilionidae, so it was reclassified into its own family, the Cistugidae, and that ''Lasionycteris'' belongs in the Vespertilioninae.Roehrs et al., 2010 The genus ''Submyotodon'' has since been added to the subfamily, making it an ...

Sassanian Period
The Sasanian Empire (), officially Eranshahr ( , "Empire of the Iranians"), was an Iranian empire that was founded and ruled by the House of Sasan from 224 to 651. Enduring for over four centuries, the length of the Sasanian dynasty's reign over ancient Iran was second only to the directly preceding Arsacid dynasty of Parthia. Founded by Ardashir I, whose rise coincided with the decline of Arsacid influence in the face of both internal and external strife, the House of Sasan was highly determined to restore the legacy of the Achaemenid Empire by expanding and consolidating the Iranian nation's dominions. Most notably, after defeating Artabanus IV of Parthia during the Battle of Hormozdgan in 224, it began competing far more zealously with the neighbouring Roman Empire than the Arsacids had, thus sparking a new phase of the Roman–Iranian Wars. This effort by Ardashir's dynasty ultimately re-established Iran as a major power of late antiquity.Norman A. Stillman ''The Jews of ...
