Murindó Fault
The Murindó Fault ( es, Falla Murindó) is a strike-slip fault in the department of Antioquia and Chocó in northwestern Colombia. The fault has a total length of and runs along an average north-northwest to south-southeast strike of 347.4 ± 6 in the Chocó Basin along the western edge of the Western Ranges of the Colombian Andes. Etymology The fault is named after Murindó.Paris et al., 2000, p.14 Description The fault in the Chocó Basin extends along the western slope of the Western Ranges of the Colombian Andes, from the Arquia River in the south to the Río Sucio and the basin of the Atrato River in the north. The Murindó Fault places Cretaceous volcanic (basic) rocks against Tertiary turbidites, and crosscuts Tertiary quartz-diorite and granodiorite. The Murindó River flows along the Murindó Fault near Murindó.Plancha 113, 2007 The fault underlies the municipalities of Dabeiba and Frontino.Plancha 128, 2002 To the south, the fault runs parallel to the ...

Colombia
Colombia (, ; ), officially the Republic of Colombia, is a country in South America with insular regions in North America—near Nicaragua's Caribbean coast—as well as in the Pacific Ocean. The Colombian mainland is bordered by the Caribbean Sea to the north, Venezuela to the east and northeast, Brazil to the southeast, Ecuador and Peru to the south and southwest, the Pacific Ocean to the west, and Panama to the northwest. Colombia is divided into 32 departments and the Capital District of Bogotá, the country's largest city. It covers an area of 1,141,748 square kilometers (440,831 sq mi), and has a population of 52 million. Colombia's cultural heritage—including language, religion, cuisine, and art—reflects its history as a Spanish colony, fusing cultural elements brought by immigration from Europe and the Middle East, with those brought by enslaved Africans, as well as with those of the various Amerindian civilizations that predate colonization.

Mutatá Fault
The Mutatá Fault ( es, Falla Mutatá) is a strike-slip fault in the department of Antioquia in northern Colombia. The fault has a total length of and runs along an average northwest to southeast strike of 326.4 ± 11 in the Urabá Basin. The fault is active and produced the 2016 Mutatá earthquake with a moment magnitude of 6.0. Etymology The fault is named after Mutatá.Paris et al., 2000, p.14 Description The Mutatá Fault is located in northwestern Colombia, between the Penderisco River and the Caribbean Sea. To the south, near the town of Mutatá, the Mutatá Fault approaches the Murrí Fault and the two fault zones practically merge. In this area, the Mutatá Fault places Cretaceous intrusive rocks and greenstones (to the east) in contact with sedimentary Tertiary rocks (to the west). Farther north, the fault cuts Tertiary and Quaternary deposits, with uplift of the eastern block. The Mutatá Fault is located near the junction of the Malpelo, Caribbean, and Nor ...

Municipalities Of Colombia
The Municipalities of Colombia are decentralized subdivisions of the Republic of Colombia. Municipalities make up most of the departments of Colombia with 1,122 municipalities (''municipios''). Each one of them is led by a mayor (''alcalde'') elected by popular vote and represents the maximum executive government official at a municipality level under the mandate of the governor of their department which is a representative of all municipalities in the department; municipalities are grouped to form departments. The municipalities of Colombia are also grouped in an association called the ''Federación Colombiana de Municipios'' (Colombian Federation of Municipalities), which functions as a union under the private law and under the constitutional right to free association to defend their common interests.

Granodiorite
Granodiorite () is a coarse-grained (phaneritic) intrusive igneous rock similar to granite, but containing more plagioclase feldspar than orthoclase feldspar. The term banatite is sometimes used informally for various rocks ranging from granite to diorite, including granodiorite. Composition According to the QAPF diagram, granodiorite has a greater than 20% quartz by volume, and between 65% and 90% of the feldspar is plagioclase. A greater amount of plagioclase would designate the rock as tonalite. Granodiorite is felsic to intermediate in composition. It is the intrusive igneous equivalent of the extrusive igneous dacite. It contains a large amount of sodium (Na) and calcium (Ca) rich plagioclase, potassium feldspar, quartz, and minor amounts of muscovite mica as the lighter colored mineral components. Biotite and amphiboles often in the form of hornblende are more abundant in granodiorite than in granite, giving it a more distinct two-toned or overall darker appearan ...

Diorite
Diorite ( ) is an intrusive igneous rock formed by the slow cooling underground of magma (molten rock) that has a moderate content of silica and a relatively low content of alkali metals. It is intermediate in composition between low-silica (mafic) gabbro and high-silica ( felsic) granite. Diorite is found in mountain-building belts (''orogens'') on the margins of continents. It has the same composition as the fine-grained volcanic rock, andesite, which is also common in orogens. Diorite has been used since prehistoric times as decorative stone. It was used by the Akkadian Empire of Sargon of Akkad for funerary sculptures, and by many later civilizations for sculptures and building stone. Description Diorite is an intrusive igneous rock composed principally of the silicate minerals plagioclase feldspar (typically andesine), biotite, hornblende, and sometimes pyroxene. The chemical composition of diorite is intermediate, between that of mafic gabbro and felsic grani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quartz
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The atoms are linked in a continuous framework of SiO4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation from α-quartz to β-quartz takes place abruptly at . Since the transformation is accompanied by a significant change in volume, it can easily induce microfracturing of ceramics or rocks passing through this temperature threshold. There are many different varieties of quartz, several of which are classified as gemstones. Since antiquity, varieties of quartz have been the most commonly used minerals in the making of jewelry and hardstone carvings, especially in Eurasia. Quartz is the mineral defining the val ...

Turbidite
A turbidite is the geologic deposit of a turbidity current, which is a type of amalgamation of fluidal and sediment gravity flow responsible for distributing vast amounts of clastic sediment into the deep ocean. Sequencing Turbidites were first properly described by Arnold H. Bouma (1962), who studied deepwater sediments and recognized particular "fining-up intervals" within deep water, fine-grained shales, which were anomalous because they started at pebble conglomerates and terminated in shales. This was anomalous because within the deep ocean it had historically been assumed that there was no mechanism by which tractional flow could carry and deposit coarse-grained sediments into the abyssal depths. Bouma cycles begin with an erosional contact of a coarse lower bed of pebble to granule conglomerate in a sandy matrix, and grade up through coarse then medium plane parallel sandstone; through cross-bedded sandstone; rippled cross-bedded sand/silty sand, and finally lami ...

Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth b ...

Atrato River
The Atrato River () is a river of northwestern Colombia. It rises in the slopes of the Western Cordillera and flows almost due north to the Gulf of Urabá (or Gulf of Darién), where it forms a large, swampy delta. Its course crosses the Chocó Department, forming that department's border with neighboring Antioquia in two places. Its total length is about , and it is navigable as far as Quibdó (400 km / 250 mi), the capital of the department. Watershed of the Atrato River The river’s total length is about , and it is navigable as far as Quibdó (400 km / 250 mi), the capital of the department. The basin occupies an area of and has an average annual precipitation of >5,000 mm/year that reaches up to 12,000 mm/year in the upper basin. Flowing through a narrow valley between the Cordillera and coastal range, it has only short tributaries, the principal ones being the Truandó, the Sucio, and the Murrí rivers.
