Boot Heel Volcanic Field
The Boot Heel volcanic field is located in the Bootheel region of southwest New Mexico, adjacent areas of southeastern Arizona, and northwest Mexico. The field covers an area of more than 24,000 km2.Baldridge, W. Scott, ''Geology of the American Southwest,'' Cambridge, 2004, pp. 219-223 The field includes nine volcanic calderas ranging in age from 26.9 to 35.3 Ma. Extrusive products include rhyolitic ignimbrites along with basalt, andesite, and rhyolite lava flows. The major ash flow tuff sheets produced, range in volume from 35 to 650 km3. Activity throughout most of the Boot Heel volcanic field paused between 33 and 28 million years ago. The earlier pulse of activity involved less evolved magmas, while the later pulse was relatively depleted in volatiles. The pause in activity has been interpreted as a period of tectonic reorganization along the west coast of North America, including the birth of the San Andreas fault, that temporarily shifted volcanism to the ...

Volatile (astrogeology)
Volatiles are the group of chemical elements and chemical compounds that can be readily vaporized. In contrast with volatiles, elements and compounds that are not readily vaporized are known as refractory substances. On planet Earth, the term 'volatiles' often refers to the volatile components of magma. In astrogeology volatiles are investigated in the crust or atmosphere of a planet or moon. Volatiles include nitrogen, carbon dioxide, ammonia, hydrogen, methane, sulfur dioxide, water and others. Planetary science Planetary scientists often classify volatiles with exceptionally low melting points, such as hydrogen and helium, as gases, whereas those volatiles with melting points above about 100 K (–173 °C, –280 °F) are referred to as ices. The terms "gas" and "ice" in this context can apply to compounds that may be solids, liquids or gases. Thus, Jupiter and Saturn are gas giants, and Uranus and Neptune are ice giants, even though the vast majority of the "gas" and ...

Volcanic Fields Of Arizona
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 ...

Peloncillo Mountains (Cochise County)
The Peloncillo Mountains of Cochise County (Spanish language ''pelo'', hair, ''pelon'', hairless, bald; ''peloncillo'', Little Baldy) is a mountain range in northeast Cochise County, Arizona. A northern north–south stretch of the range extends to the southern region of Greenlee County on the northeast, and a southeast region of Graham County on the northwest. The north stretch of the Peloncillo's forms the border between the two counties. It lies east and northeast of the Willcox Playa, and the San Simon Valley. The range lies in a region of southeast Arizona and southwest New Mexico called the Madrean Sky Islands. Description The Peloncillo Mountains of Cochise County are a long range. The north section is oriented north–south, and is bordered on the north by the Gila River which flows west-northwesterly from western New Mexico. The Whitlock Valley and Whitlock Mountains border to the west. The southern section of the range is a northwest by southeast region, and contai ...

Chiricahua National Monument
Chiricahua National Monument is a unit of the National Park System located in the Chiricahua Mountains of southeastern Arizona. The monument was established on April 18, 1924, to protect its extensive hoodoos and balancing rocks. The Faraway Ranch, which was owned at one time by Swedish immigrants Neil and Emma Erickson, is also preserved within the monument. Just over 85% of the monument is protected as the Chiricahua National Monument Wilderness. Visitor center A visitor center is located two miles from the entrance to Chiricahua National Monument. The visitor center has exhibits relating to the geology, natural history, and cultural history of the area. A park ranger is available to provide visitors with trail guides and information. The main road, Bonita Canyon Drive, ventures east through the park, ending at Massai Point. Approximately of trails lead hikers through various ecosystems of meadows, forests, and rock formations. The visitor center has a free shuttle that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chiricahua Mountains
The Chiricahua Mountains massif is a large mountain range in southeastern Arizona which is part of the Basin and Range province of the west and southwestern United States and northwest Mexico; the range is part of the Coronado National Forest. The highest point, Chiricahua Peak, rises above sea level, approximately above the surrounding valleys. The range takes its name from the Chiricahua Apaches native to the region. The Chiricahua Mountains and other associated ranges, along with Sulphur Springs Valley on the west and the San Simon Valley on the east, form the eastern half of Cochise County in southeast Arizona. The Pedregosa Mountains are found at the southern end of the Chiricahua Mountains, while the Swisshelm Mountains are located to the southwest. The northwest end of the Chiricahua mountains continue as the Dos Cabezas Mountains beyond Apache Pass and the Fort Bowie National Historic Site.

Pyramid Mountains
The Pyramid Mountains are a 30 mi (48 km) long, mountain range in central-east Hidalgo County, New Mexico. The city of Lordsburg and Interstate 10 lie at its northern border.

Monogenetic Volcanic Field
A monogenetic volcanic field is a type of volcanic field consisting of a group of small monogenetic volcanoes, each of which erupts only once, as opposed to polygenetic volcanoes, which erupt repeatedly over a period of time. The small monogenetic volcanoes of these fields are the most common subaerial volcanic landform. Many monogenetic volcanoes are cinder cones, often with lava flows, such as Parícutin in the Michoacán-Guanajuato volcanic field, which erupted from 1943 to 1952. Some monogenetic volcanoes are small lava shields, such as Rangitoto Island in the Auckland volcanic field. Other monogenetic volcanoes are tuff rings or maars. A monogenetic field typically contains between ten and a hundred volcanoes. The Michoacán-Guanajuato field in Mexico contains more than a thousand volcanoes and is exceptionally large. Monogenetic fields occur only where the magma supply to the volcano is low or where vents are not close enough or large enough to develop plumbing systems f ...

San Bernardino Valley (Arizona)
The San Bernardino Valley of Arizona is a northeast-by-southwest trending valley in extreme southeast Cochise County, Arizona. The north end of the valley merges into the northwest-by-southeast trending San Simon Valley; both merge in western perimeter Hidaldgo County, New Mexico. The valley is an asymmetric graben.
