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 ...

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 …

Clear Lake Volcanic Field is located about 90 miles north of San Francisco, California. The town of Clearlake lies within the volcanic field, as does much of the 43,000-acre freshwater lake of its namesake.

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.

2023年12月7日 · The earliest eruptions within the Boring Volcanic Field occurred in the southern part of the Portland Basin, south of present day Oregon City. Volcanic activity between 2.6 and 2.4 million years ago produced widely dispersed lava flows, the Highland Butte shield, and several monogenetic cinder cones and lava flows.

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.

The Uinkaret volcanic field is an area of monogenetic volcanoes in northwestern Arizona, United States, located on the north rim of the Grand Canyon. [2] Lava flows from the Uinkaret volcanic field that have cascaded down into the Grand Canyon, damming the Colorado River, have been used to date the canyon's carving. [3]

On Earth, volcanism occurs in several distinct geologic settings. Most of these are associated with the boundaries of the enormous rigid plates that make up the lithosphere —the crust and upper mantle.

The Carrizozo volcanic field is a monogenetic volcanic field located in New Mexico, US. The volcanic field consists of two lava flows, the Broken Back flow and the Carrizozo lava flow (Carrizozo Malpais), the second youngest in New Mexico. [5] Both lava flows originated from groups of cinder cones. The Broken Back flow is approximately 16 ...

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.
