The Drina Formation ("Drina Formacija") is a stratigraphic unit in Bosnia and Herzegovina and Serbia. [2] It was deposited between the Cambrian and the Carboniferous onto Neoproterozoic basement. [3] It is composed of clastic sediments, limestone and volcanic rocks. [1] The Drina Formation is conformably overlain by the Golja Formation. [3]

The formation is part of the Drina Ivanjica Unit and was overprinted by the Variscan and Alpine Orogeny. [3]

The oldest fossils are acritarch phytoplancton and spores, which indicate a Cambrian to Ordovician age. The youngest fossils are conodonts which indicate Viséan to Namurian age. [3]

<span class="mw-page-title-main">Geologic time scale</span> System that relates geologic strata to time

The geologic time scale or geological time scale (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy and geochronology. It is used primarily by Earth scientists to describe the timing and relationships of events in geologic history. The time scale has been developed through the study of rock layers and the observation of their relationships and identifying features such as lithologies, paleomagnetic properties, and fossils. The definition of standardised international units of geological time is the responsibility of the International Commission on Stratigraphy (ICS), a constituent body of the International Union of Geological Sciences (IUGS), whose primary objective is to precisely define global chronostratigraphic units of the International Chronostratigraphic Chart (ICC) that are used to define divisions of geological time. The chronostratigraphic divisions are in turn used to define geochronologic units.

The Army of Republika Srpska, commonly referred to in English as the Bosnian Serb Army, was the military of Republika Srpska, the self-proclaimed Serb secessionist republic, a territory within the newly independent Bosnia and Herzegovina, which it defied and fought against. Active during the Bosnian War from 1992 to 1995, it continued to exist as the armed forces of RS, one of two entities making up Bosnia and Herzegovina, until 2006 when it was integrated into the Armed Forces of Bosnia and Herzegovina. Forces of the VRS engaged in several campaigns, including Operation Corridor 92, Operation Vrbas '92, Operation Bura, and Operation Spider; they were also involved in the siege of Sarajevo, as well as the Srebrenica massacre.

<i>The Bridge on the Drina</i> Historical novel by the writer Ivo Andrić

The Bridge on the Drina is a historical novel by the Yugoslav writer Ivo Andrić. It revolves around the Mehmed Paša Sokolović Bridge in Višegrad, which spans the Drina River and stands as a silent witness to history from its construction by the Ottomans in the mid-16th century until its partial destruction during World War I. The story spans about four centuries and covers the Ottoman and Austro-Hungarian occupations of the region, with a particular emphasis on the lives, destinies, and relations of the local inhabitants, especially Serbs and Bosnian Muslims.

Podrinje is the Slavic name of the Drina river basin, known in English as the Drina Valley. The Drina basin is shared between Bosnia and Herzegovina and Serbia, with majority of its territory being located in Eastern Bosnia, entire Upper Drina course and majority of the Middle course, while the Lower Drina course is shared between two countries, with the river representing border. The part of the Drina basin located in Bosnia and Herzegovina is also called Eastern Bosnia.

<span class="mw-page-title-main">Stephen Formation</span>

The Stephen Formation is a geologic formation exposed in the Canadian Rockies of British Columbia and Alberta, on the western edge of the Western Canada Sedimentary Basin. It consists of shale, thin-bedded limestone, and siltstone that was deposited during Middle Cambrian time. It is famous for the exceptional preservation of soft-bodied fossils: the Burgess Shale biota. The formation overlies the Cathedral escarpment, a submarine cliff; consequently it is divided into two quite separate parts, the 'thin' sequence deposited in the shallower waters atop the escarpment, and the 'thick' sequence deposited in the deeper waters beyond the cliff. Because the 'thick' Stephen Formation represents a distinct lithofacies, some authors suggest it warrants its own name, and dub it the Burgess Shale Formation. The stratigraphy of the Thin Stephen Formation has not been subject to extensive study, so except where explicitly mentioned this article applies mainly to the Thick Stephen Formation.

The Cathedral Formation is a stratigraphic unit in the southern Canadian Rockies of Alberta and British Columbia, on the western edge of the Western Canada Sedimentary Basin.

<span class="mw-page-title-main">Tonto Group</span> Cambrian geologic unit in the Grand Canyon region, Arizona

The Tonto Group is a name for an assemblage of related sedimentary strata, collectively known by geologists as a Group, that comprises the basal sequence Paleozoic strata exposed in the sides of the Grand Canyon. As currently defined, the Tonto groups consists of the Sixtymile Formation, Tapeats Sandstone, Bright Angel Shale, Muav Limestone, and Frenchman Mountain Dolostone. Historically, it included only the Tapeats Sandstone, Bright Angel Shale, and Muav Limestone. Because these units are defined by lithology and three of them interfinger and intergrade laterally, they lack the simple layer cake geology as they are typically portrayed as having and geological mapping of them is complicated.

The Neoproterozoic Nankoweap Formation, is a thin sequence of distinctive red beds that consist of reddish brown and tan sandstones and subordinate siltstones and mudrocks that unconformably overlie basaltic lava flows of the Cardenas Basalt of the Unkar Group and underlie the sedimentary strata of the Galeros Formation of the Chuar Group. The Nankoweap Formation is slightly more than 100 m in thickness. It is informally subdivided into informal lower and upper members that are separated and enclosed by unconformities. Its lower (ferruginous) member is 0 to 15 m thick. The Grand Canyon Supergroup, of which the Nankoweap Formation is part, unconformably overlies deeply eroded granites, gneisses, pegmatites, and schists that comprise Vishnu Basement Rocks.

<span class="mw-page-title-main">Shackleton Limestone</span>

The Shackleton Limestone is a Cambrian limestone formation of the Byrd Group of Antarctica. The age of the formation is established to be Cambrian Stage 3, dated at ranging from 520 to 516 Ma. This period correlates with the End-Botomian mass extinction. Fossils of trilobites and Marocella mira and Dailyatia have been found in the formation, named after Ernest Shackleton, who led a failed expedition into Antarctica. At time of deposition, the Antarctic Plate has been established to be just south of the equator as part of the supercontinent Pannotia, contrasting with its present position at 82 degrees southern latitude.

One of the major depositional strata in the Himalaya is the Lesser Himalayan Strata from the Paleozoic to Mesozoic eras. It had a quite different marine succession during the Paleozoic, as most parts of it are sparsely fossiliferous or even devoid of any well-defined fossils. Moreover, it consists of many varied lithofacies, making correlation work more difficult. This article describes the major formations of the Paleozoic – Mesozoic Lesser Himalayan Strata, including the Tal Formation, Gondwana Strata, Singtali Formation and Subathu Formation.

<i>Zemlja</i> (feudal Bosnia) Unit of territory in medieval Bosnia

Zemlja, was a term used in the Balkans during much of the Middle Ages as a unit in political-territorial state division, based on feudal social hierarchy, local administrative control and the feudal distribution of land. It was the largest unit of administration, which constituted a feudal state among South Slavic peoples of the Balkans at the time, Bosnia, Croatia, Montenegro (Zeta) and Serbia. The same term is known to be used among other Slavic nations of medieval Europe, namely Poles and Russians, who called it Zemlya, Ziemlia, or Ziemia, and although it has a similar meaning and significance it is not the same.
