A volcanic field is an area of Earth's crust that is prone to localized volcanic activity. The type and number of volcanoes required to be called a "field" is not well-defined. [1] Volcanic fields usually consist of clusters of up to 100 volcanoes such as cinder cones. Lava flows may also occur. They may occur as a monogenetic volcanic field or ...

Northern Arizona's San Francisco Volcanic Field, which covers about 4,700 square kilometers (1,800 square miles), is an area of young volcanoes along the southern margin of the Colorado Plateau. Much of the field lies within Coconino and Kaibab National Forests.

2023年4月17日 · Volcanic fields are clusters of volcanoes or areas covered by volcanic rocks. Monogenetic volcanic fields consist mostly (or exclusively) of monogenetic volcanoes. These volcanoes (cinder cones, maars, tuff rings, and eruptive fissures) each experience one period of …

2020年4月20日 · Volcanic fields are regions of volcanic activity that tap one magma source. Eruptions in the RCVF began approximately 9 million years ago, with Capulin's eruption taking place between 56,000 and 62,000 years ago. Potential still exists for future eruptions from dormant volcanoes in the field today.

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.

Arizona boasts seven young (Quaternary) volcanic fields; young, that is, by geologic standards. The three youngest fields are the San Francisco, Uinkaret, and Pinacate volcanic fields. The former two reside on the Colorado Plateau of northern Arizona; the Pinacate field is situated on the Arizona-Mexico frontier about 40 miles south-southwest ...

Springerville volcanic field is a monogenetic volcanic field located in east-central Arizona between Springerville and Show Low. The field consists of 405 discrete vents [ 3 ] covering approximately 3,000 square kilometers (1,200 sq mi) [ 2 ] and is the third-largest such field in the continental United States; [ 4 ] only the San Francisco ...

2022年9月8日 · Volcanic fields mark the locations where magma is created under the planetary surface but cannot be extruded by the repeated use of a single conduit. Their lateral extension therefore is likely to delineate the dimensions of magma reservoirs at depth in a form that differs from the presence of isolated volcanic structures.

In volcano: Volcanic fields. Such areas have many geologically young cinder cones or other features that have not been individually identified as separate volcanoes. If the conduits through which magma ascends to the surface are scattered over a broad area, many short-lived volcanoes are formed rather than… Read More

A volcanic field is an area on the Earth's crust that is prone to localized volcanic activity and is usually covered with volcanic materials produced during past eruptions. A volcanic field may have been active during a single eruptive event, during a protracted period of related volcanic activity, or during unrelated periods of activity widely ...
