The Potrillo volcanic field is a monogenetic volcanic field located on the Rio Grande Rift in southern New Mexico, United States and northern Chihuahua, Mexico. The volcanic field lies 22 miles (35 km) southwest of Las Cruces , and occupies about 4,661 square kilometers (1,800 sq mi) near the U.S. border with Mexico.
Hotspot volcanoes are considered to have a fundamentally different origin from island arc volcanoes. The latter form over subduction zones, at converging plate boundaries. When one oceanic plate meets another, the denser plate is forced downward into a deep ocean trench.
Subsequent studies have demonstrated that loggerhead and green turtles can also use the magnetic field of the earth as a map, because different parameters of the Earth's magnetic field vary with geographic location. The map in sea turtles was the first ever described though similar abilities have now been reported in lobsters, fish, and birds. [48]
The Anahim Volcanic Belt can be organized into three groupings: the western section, which has been reduced to remnants of eruptive breccia, high-level plutons and dike swarms; the central section, which consists of predominantly shield volcanoes; and the eastern section, which comprises several small cinder cones and is the location of all ...
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 km 2. [2] The field includes nine volcanic calderas ranging in age from 26.9 to 35.3 Ma.
Vulcan's Throne is a cinder cone volcano and a prominent landmark on the North Rim of the Grand Canyon in Arizona, United States. [4] The volcano is adjacent the Colorado River, (thousands of feet above the river) as it is the source material for Lava Falls and Lava Falls Rapids (Vulcan Rapids) one of the largest rapids of the Colorado.
The vast majority of volcanic provinces which are thought to be anomalous in the context of rigid plate tectonics have now been explained using the plate theory. [15] [14] The type examples of this kind of volcanic activity are Iceland, Yellowstone, and Hawaii. Iceland is the type example of a volcanic anomaly situated on a plate boundary.
Elysium contains the major volcanoes Elysium Mons, Albor Tholus and Hecates Tholus. Another more ancient shield volcano, Apollinaris Mons, is situated just to the south of eastern Elysium Planitia. Within the plains, Cerberus Fossae is the only Mars location with recent volcanic eruptions.
