A volcanic plateau is a plateau produced by ... Lava plateaus are formed by highly fluid basaltic lava during numerous successive eruptions through numerous vents ...
Volcanic plateaus are produced by volcanic activity. The Columbia Plateau in the north-western United States is an example. They may be formed by upwelling of volcanic magma or extrusion of lava. The underlining mechanism in forming plateaus from upwelling starts when magma rises from the mantle, causing the ground to swell upward. In this way ...
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.
The Markagunt Plateau is part of the High Plateaus geologic province, in the Colorado Plateau [23] and at its margins with the Basin and Range Province. It is a 60–80 kilometres (37–50 mi) wide fault -bounded block [ 7 ] and the basement underneath the volcanoes is formed by various Cretaceous to Miocene sedimentary or volcanic rocks. [ 24 ]
It is subdivided into Maharashtra Plateau, Karnataka Plateau, and Telangana Plateau. The Deccan Traps in the north west were formed by multiple layers of igneous rocks laid down by basaltic lava flows following a massive volcanic eruption that occurred during the end of the cretaceous period (66 mya ).
Upper Table Rock and Lower Table Rock are two prominent volcanic plateaus located just north of the Rogue River in Jackson County, Oregon, U.S. Created by an andesitic lava flow approximately seven million years ago and shaped by erosion, they now stand about 800 feet (240 m) above the surrounding Rogue Valley.
A hotspot volcano is center. [8] Movements of tectonic plates create volcanoes along the plate boundaries, which erupt and form mountains. A volcanic arc system is a series of volcanoes that form near a subduction zone where the crust of a sinking oceanic plate melts and drags water down with the subducting crust. [9]
The Yellowstone Plateau Volcanic Field, also known as the Yellowstone Supervolcano or the Yellowstone Volcano, is a complex volcano, volcanic plateau and volcanic field located mostly in the western U.S. state of Wyoming, but it also stretches into Idaho and Montana. [4] [5] It is a popular site for tourists. [6] Map of Yellowstone Volcano ash beds
