Uranius Group Of Volcanoes
The Uranius group of volcanoes is located on planet Mars in the northeast part of Tharsis and includes Uranius Mons, Ceraunius Tholus, and Uranius Tholus. Along with the Tharsis Montes to the southwest, they form part of a linear chain of volcanoes in the Tharsis region. They are dated to the Late Hesperian The Hesperian is a system (stratigraphy), geologic system and geologic timescale, time period on the planet Mars characterized by widespread Volcanology of Mars, volcanic activity and catastrophic flooding that carved immense outflow channels acr ... Epoch and are part of earliest phases of volcanism in the Tharsis province. All three volcanoes are interpreted as basaltic shields. The volcanoes of the Uranius group were active for short periods of time (10 000–100 000 years) and are significantly older than the major Tharsis volcanoes.Lunar and Planetary Science XXX, GEOLOGY OF URANIUS PATERA, MARS.

Uranius Group
Uranius is the name of two possible Roman usurpers of the third century. The first Uranius is mentioned only by Zosimus, and was briefly active during the latter part of the reign of Alexander Severus. He was chosen by dissatisfied soldiers along the Danube and from a lowly background. There is little confirmatory evidence of his existence. A second, and better attested usurper was Lucius Julius Aurelius Sulpicius Severus Uranius Antoninus, who appears to have been active in Syria in the early 250s. Coins minted in Emesa have been found bearing his name, and invoking the local deity Sol Invictus. Some scholars have connected him to an Emesan priest active in this period, known as Sampsiceramus. It is not clear whether the coins that were struck in Syria belong to the same man (or men) spoken about in the texts. If the later date is correct Uranius might have helped defend the Roman Empire against Shapur I, the Sassanid king of Persia Iran, officially the Islamic ...

Tharsis
Tharsis () is a vast volcanic plateau centered near the equator in the western hemisphere of Mars. The region is home to the largest volcanoes in the Solar System, including the three enormous shield volcanoes Arsia Mons, Pavonis Mons, and Ascraeus Mons, which are collectively known as the Tharsis Montes. The tallest volcano on the planet, Olympus Mons, is often associated with the Tharsis region but is actually located off the western edge of the plateau. The name Tharsis is the Greco-Latin transliteration of the biblical Tarshish, the land at the western extremity of the known world. Location and size Tharsis can have many meanings depending on historical and scientific context. The name is commonly used in a broad sense to represent a continent-sized region of anomalously elevated terrain centered just south of the equator around longitude 265°E.Carr, M.H. (2006).

Uranius Mons
Uranius Mons, formerly Uranius Patera, is a volcano on Mars located in the Tharsis quadrangle, named after a classical albedo feature. The name "Uranius Patera" now refers only to the volcano's central caldera. It is high and has shallow slopes. It belongs to the Uranius group of volcanoes in the Tharsis area. The sides of Uranius Mons consist of radial lava flows; the large caldera (90×65 km) is elongated in the southwestern direction. The surrounding plains are younger and part of the Tharsis Montes Formation of the Amazonian epoch The geology of Mars is the scientific study of the surface, crust (geology), crust, and interior of the planet Mars. It emphasizes the composition, structure, history, and physical processes that shape the planet. It is analogous to the field of ....Lunar and Planetary Science XXX, Geology of Uranius Patera, Mars.

Ceraunius Tholus
Ceraunius Tholus is a volcano on Mars located in the Tharsis quadrangle at 24.25° north latitude and 262.75° east longitude, part of the Uranius group of volcanoes. It is across, approximately high and is named after a classical albedo feature name. It is generally believed to be a basaltic shield with the lower part buried beneath plain forming lavas. Earlier interpretations suggested that it is a stratovolcano. The slopes on Ceraunius Tholus are quite steep with an average slope of 8° with many radial erosion channels and pitted valleys extending from just below the rim of the caldera toward the base of the volcano. The current view is that the valleys were eroded by water. Interesting features on Ceraunius Tholus are three large canyons at the northwest flank of Ceraunius Tholus which are up to 2.5 km wide and 300 m deep. The biggest of these three also appears to be the youngest and protrude from the lowest point of the volcanic caldera and ends at the interesting ...

Uranius Tholus
Uranius Tholus is a volcano on Mars located in the Tharsis quadrangle at 26.52° north latitude and 262.43° east longitude. It is across with an elevation of and was named after a classical albedo feature name. Uranius Tholus is part of the Uranius group of volcanoes and lies north of the larger Ceraunius Tholus. Volcanoes Tharsis is a land of great volcanoes. Olympus Mons is the tallest known volcano. "Mons" is a term used for a large raised feature. "Tholus" is about the same, but smaller.

Tharsis Montes
The Tharsis Montes () are three large shield volcanoes in the Tharsis region of the planet Mars. From north to south, the volcanoes are Ascraeus Mons, Pavonis Mons and Arsia Mons. Mons (plural ''montes'') is the Latin word for mountain; it is a descriptor term used in astrogeology for mountainous features in the Solar System. The three Tharsis Montes volcanoes are enormous by terrestrial standards, ranging in diameter from (Pavonis Mons) to (Arsia Mons). Ascraeus Mons is the tallest with a summit elevation of over , or base-to-peak. For comparison, the tallest volcano on Earth, Mauna Kea in Hawaii, is about across and stands above the ocean floor. The Tharsis Montes volcanoes lie near the equator, along the crest of a vast volcanic plateau called the Tharsis region or Tharsis bulge. The Tharsis region is thousands of kilometers across and averages nearly above the mean elevation of the planet. Olympus Mons, the tallest known mountain in the Solar System, is located about ...

Hesperian
The Hesperian is a system (stratigraphy), geologic system and geologic timescale, time period on the planet Mars characterized by widespread Volcanology of Mars, volcanic activity and catastrophic flooding that carved immense outflow channels across the surface. The Hesperian is an intermediate and transitional period of Martian history. During the Hesperian, Mars changed from the wetter and perhaps warmer world of the Noachian (Mars), Noachian to the dry, cold, and dusty planet seen today. The absolute age of the Hesperian Period is uncertain. The beginning of the period followed the end of the Late Heavy Bombardment and probably corresponds to the start of the lunar Late Imbrian period, around 3700 million years ago (Myr, Mya). The end of the Hesperian Period is much more uncertain and could range anywhere from 3200 to 2000 Mya, with 3000 Mya being frequently cited. The Hesperian Period is roughly coincident with the Earth's early Archean Eon. With the decline of heavy impacts a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanoes Of Mars
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide pa ...
