Vargeão Dome
Vargeão Dome is a meteorite impact crater, crater in Santa Catarina (state), Santa Catarina State, Brazil, straddling the municipalities of Vargeão, Faxinal dos Guedes, and Passos Maia. The crater is an almost perfectly circular depression with steep walls, in diameter and up to deep, relative to its rim. It is of Early Cretaceous age, or about 123 ± 2 Ma. The meteorite impacted on the basaltic rocks of the Serra Geral Formation (Jurassic/Cretaceous). The crater displays several concentric rings and radial faults, and an eroded central bulge. The latter consists of impact breccias and sandstones from the Botucatu Formation, Botucatu/Pirambóia Formation (Cretaceous/Triassic), which have been displaced about above their mean depth in the surrounding area. At least four post-impact lava flows have been identified between the rim and core. The impact origin of the structure is attested by the presence of shatter cones and shocked quartz grains.

Paraná Basin
The Paraná Basin (, ) is a large cratonic sedimentary basin situated in the central-eastern part of South America. About 75% of its areal distribution occurs in Brazil, from Mato Grosso to Rio Grande do Sul states. The remainder area is distributed in eastern Paraguay, northeastern Argentina and northern Uruguay. The shape of the depression is roughly Ellipse, elliptical and covers an area of about . The Paraná River, from which the Paraná Basin derived its name, flows along the central axis of the Paraná Basin and drains it. Description The Paraná Basin stretches from the Brazilian state of Mato Grosso in the north to northern Argentina and Uruguay in the south. The southern portion in Uruguay is locally known as Norte Basin.De Santa Ana et al., 2004, p.88Daners et al., 2006, p.148 Pioneer studies The first study on the Brazilian side of the Paraná Basin dates from 1841, when a Brazilian Empire, Brazilian Imperial Government Mission prospected for coal.

Cretaceous Impact Craters
The Cretaceous ( ) is a geological period that lasted from about 143.1 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 77.1 million years, it is the ninth and longest geological period of the entire Phanerozoic. The name is derived from the Latin , 'chalk', which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation . 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 largely ice-free, although there is some evidence of brief periods of glaciation during the cooler first half, and forests extended to the poles. Many of the dominant taxonomic groups present in modern times can be ultimately traced back to origins in the C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vista Alegre Crater
The Vista Alegre crater is a meteorite crater in Coronel Vivida, Paraná State, Brazil. On the surface it appears as a circular, relatively flat plain within otherwise hilly terrain. Description It is in diameter and the age is estimated to be less than 65 million years (Paleocene or younger). More recently, a date of about 115 Ma has been givenA. Crósta, M. Vasconcelos (2013)Update On The Current Knowledge Of The Brazilian Impact Craters 44th Lunar and Planetary Science Conference (2013) and closer to the age of Vargeão Dome. Considering the proximity of location, age, and stratigraphic similarities of Vista Alegre and Vargeão, it has been proposed that it was a double impact.A. Crósta, C. Kazzuo-Vieira and A.

City Hall
In local government, a city hall, town hall, civic centre (in the UK or Australia), guildhall, or municipal hall (in the Philippines) is the chief administrative building of a city, town, or other municipality. It usually houses the city or town council and at least some other arms of the local government. It also often functions as the office of the mayor (or other executive), if the relevant municipality has such an officer. In large cities, the local government is often administratively expansive, and the city hall may bear more resemblance to a municipal capitol building. By convention, until the middle of the 19th century, a single large open chamber (or "hall") formed an integral part of the building housing the council and such other organs of government as supported it. The hall may be used for council meetings and other significant events. This large chamber, the "town hall" (and its later variant "city hall") became synonymous with the whole building, and, synec ...

Maskelynite
Maskelynite is a glassy material found in some meteorites and meteorite impact craters. Typical samples are similar in composition to plagioclase feldspar, and revert to that mineral when melted and recrystallized. It was named after British people, British geologist Nevil Story Maskelyne, M.H.N. Story-Maskelyne. Since maskelynite (like the volcano, volcanic glass obsidian) lacks an orderly arrangement of atoms, it is not considered a "mineral" by geologists, and is not listed as such by the Mineralogical Society of America. History The phase was first identified in the Shergotty meteorite by Gustav Tschermak von Seysenegg, G. Tschermak (1872) as an isotropic glass of an unknown origin with near labradorite composition. Similar phases were found in chondrites and Mars meteorite, Martian meteorites. In 1963, D. J. Milton and P. S. de Carli produced a maskelynite-like glass by subjecting gabbro to an explosive shock wave. In 1967, T. E. Bunch and others identified maskelynite in the ...

Tectonic
Tectonics ( via Latin ) are the processes that result in the structure and properties of the Earth's crust and its evolution through time. The field of ''planetary tectonics'' extends the concept to other planets and moons. These processes include those of mountain-building, the growth and behavior of the strong, old cores of continents known as cratons, and the ways in which the relatively rigid plates that constitute the Earth's outer shell interact with each other. Principles of tectonics also provide a framework for understanding the earthquake and volcanic belts that directly affect much of the global population. Tectonic studies are important as guides for economic geologists searching for fossil fuels and ore deposits of metallic and nonmetallic resources. An understanding of tectonic principles can help geomorphologists to explain erosion patterns and other Earth-surface features.
