Lava plateau

Lava plateaus are formed by highly fluid mafic lava (the older term is basic lava) during numerous successive eruptions through numerous vents without violent explosions (quiet eruptions). These eruptions are quiet because of low viscosity of mafic lava, so that it is very fluid and contains small amount of trapped gases. The resulting sheet lava flows may be extruded from linear fissures or rifts or gigantic volcanic eruptions through multiple vents characteristic of the prehistoric era which produced giant flood basalts. Multiple successive and extensive lava flows cover the original landscape to eventually form a plateau, which may contain lava fields, cinder cones, shield volcanos and other volcanic landforms. In geology, mafic minerals and rocks are silicate minerals, magmas, and volcanic and intrusive igneous rocks that have relatively high concentrations of the heavier elements. ...

The Earth features numerous subaerial and submarine volcanic plateaus such as the Columbia River Plateau (subaerial) and the vast Ontong Java Plateau (submarine). The term subaerial, mainly used in geology, describes events or structures located at the Earths surface, under the air. This is to be contrasted with submarine events or structures, those located under the sea. ... Submarine volcanoes and volcanic vents are common features on certain zones of the ocean floor. ... The Columbia River Plateau is shown in green on this map. ... The Ontong Java Plateau is a huge undersea plateau located in the Pacific Ocean, lying north of the Solomon Islands. ...

Pyroclastic plateau

Pyroclastic plateaus are produced by massive pyroclastic flows and they are underlain by pyroclastic rocks: agglomerates, tephra, volcanic ashes cemented into tuffs, mafic or felsic. Pyroclastic flows are a common and devastating result of some volcanic eruptions. ... Pyroclastic rocks or pyroclastics (derived from the Greek πῦρ, meaning fire, and κλαστός, meaning broken) are debris thrown from volcanoes during an eruption. ...
