Basaltic lava that solidifies under water and develops a structure that resembles a pile of pillows.
Bulbous masses of basalt resembling pillows formed when lava is rapidly chilled under water.
Volcanic rock with unusual pillow structure caused by lava cooling under water.
An ellipsoidal mass of igneous rock formed by extrusion of lava underwater.
lava that hardened in rounded shapes suggestive of pillows; believed to result from underwater eruptions
a lava with a distinctive shape acquired by basalt that erupts into a submarine environment
Interconnected lobs of lava formed underwater by submarine activity.
Lava formed when hot gases and liquid bubble up through the sea floor and harden. This lava then becomes part of a new seabed.
Interconnected, sack-like bodies of lava formed underwater.
a form lava takes when it erupts underwater - it makes pillow-shaped blobs
a general term for those lavas displaying pillow structures (globs of lava with curved tops and "pinched" bottoms) and considered to have formed under water.
Lava extruded beneath water characterised by pillow-type shapes.
lava that erupts under water and forms rocks that display a typical rounded, pillow shape.
Fluid lava erupted or flowing under water which squeezes out through thin walls of submarine tubes like toothpaste and quickly solidifies forming glassy outer skin; sack or pillow-shaped in cross section ranging up to about 1 meter in diameter. Erupted under high pressure due to overlying water, so little or no explosive interaction between hot lava and cold water.
Globular masses of volcanic rock formed when lava flows into a body of water.
submarine lava, usually of a basaltic kind, found in the form of round, closely packed masses. [AHDOS
Pillow lava is lava that cools under the sea, with an interconnected, sack-like form.
A lava flow that has rounded or tube-like masses making up its surface as a result of having occurred underwater where each emerging surge of lava was rapidly cooled to create the distinct shapes.
