Pillow lava - Wikipedia
Pillow lava on the ocean floor of Hawaii. Pillow lavas are lavas that contain characteristic pillow-shaped structures that are attributed to the extrusion of the lava underwater, or subaqueous extrusion.

Nov 17, 2023 · Pillow lava is a type of basaltic lava that forms underwater, typically in the ocean. It gets its name from the characteristic pillow-like shapes that the lava takes on as it rapidly cools and solidifies in the cold water.

Pillow lavas are bulbous, spherical, or tubular lobes of lava. They form during eruptions with relatively low effusion rates. Slow extrusion gives enough time for a thick crust to form on all sides of a pillow lobe, and prevents individual pillows from coalescing into a sheet.

In lava …third type of mafic lava, pillow lava, is named for the pillow-shaped masses that form underwater as highly fluid lava is quenched by the surrounding water (see also igneous rock). Read More; subglacial volcanic activity
What Are Pillow Lavas? How and Where Do the Form?
Aug 10, 2023 · Pillow lavas are mound-like tubular, nearly spherical, or pillow-shaped structures associated primarily with submarine or underwater basaltic volcanism. They usually measure 0.1-1 meter or more and may have a smooth, corrugated, striated, or cracked glassy rind with a more crystalline interior.
Pillow Lava - NOAA Ocean Exploration
Cold seawater chills the erupting lava, creating a rounded tube of basalt crust that looks like a pillow. As the newly erupting lava pushes through the chilled basalt crust, it can form scratches on the pillow surface, called striations. Learn more.

Dec 27, 2022 · Pillow lava is a form of effusive (i.e., erupted at the surface) igneous rock which results when low-viscosity magma such as basalt erupts under water. Pillows are irregular tube-like structures, circular to elliptical in cross-section, typically 30 cm to about 1 m in diameter.
