The two main types of lava field structures are defined as sheet flow lava and pillow lava. Sheet flow lava appears like a wrinkled or folded sheet, while pillow lava is bulbous, and often looks like a pile of pillows atop one another. [2] An important aspect of lava flow morphology is a phenomenon known as lava flow inflation.
Boring Lava was erupted by vents in the volcanic field, [6] [74] and it has been exposed at elevated topographic levels in intact volcanic cones and dissected lava plains. There is likely more lava deposited under Quaternary sedimentary mantle throughout the region, [6] though activity was confined to a relatively concentrated area. [75]
Four Craters Lava Field is a basaltic volcanic field located south east of Newberry Caldera in the U.S. state of Oregon. [1] The volcanic field covers about 30 square kilometers and post-dates Mount Mazama's eruption. [3] Four Holocene cinder cones are the source of the flows in the field and are aligned along a fissure trending N 30° W. The ...
An example is the massive Level Mountain shield volcano in northern British Columbia, Canada, which covers an area of 1,800 km 2 (690 sq mi) and a volume of 860 km 3 (210 cu mi). [ 1 ] Perhaps the most extensive of all the subaerial basaltic plateaus existed during the Paleogene [ 2 ] and possibly extended over 1,800,000 km 2 (690,000 sq mi) of ...
The Hell's Half Acre lava plain is located in Bingham and Bonneville counties in the state of Idaho. The site is about 150 square miles (390 km 2) in size. [1] The area where a former lava lake existed is marked by a 875-yard (800 m) long by 328-yard (300 m) wide depression near the summit of the lava field. [7]
Most of the ones found so far are in the Moon’s ancient lava plains – but there might be some around the Moon’s south pole, where Nasa intends to land later this decade.
Some of the lava flows of Markagunt Plateau are among the youngest in Utah; these are sparsely vegetated [9] and blocky, [12] while others are cut by streams and stream terraces. [10] Bowers Cave and Mammoth Cave are lava tubes set in lava flows on the Markagunt Plateau, [ 11 ] the 3.7 kilometres (12,000 ft) long Duck Creek Lava Tube is among ...
The pit, like the more than 200 others discovered up there, was created by the collapse of a lava tube. ... Most of the pits seem to be located in the moon’s ancient lava plains, according to ...
