The pillow lava originates from the pillow basaltic lava in the mid-ocean spreading ridge, including basalt and spilite, and there is a lava geo-heritage located in the joint area of three villages: Qunrang, Gangta and Duigang of Jiacuosong Township, Sangzhuyi District, Shigatse City, Tibet, China.
When lava emerges under the ocean, it immediately cools and forms a crust -- known as "pillow lava".
The basaltic lava of this ophiolite are divided into two types :(1) pillow lava (2) spilitic basalts.
Using data from NASA's Mars Reconnaissance Orbiter, Scanlon found pillow lava formations, similar to those that form on Earth when lava erupts at the bottom of an ocean.

Somehow, the cable snagged a huge pillow lava in a nook between two bulbous lobes and wrenched it up from the seafloor.
Be it the outcrops of crystalline rocks at Jebel Qahwan in north of Bilad Bani Bu Ali, the brown crystalline rocks of the Samail ophiolites, huge piles of pillow lava in Wadi Al Jizzi, Stone Park at Duqm, or the beautiful layering of sedimentary beds at Jebel Samhan in Dhofar, each location narrates the stories of Oman's geological history.
The lowermost 8 meters of the basalt contain four types of mineralized structures: (1) pillow lava, (2) scoria (3) amygdaloidal basalt and (4) veins.
Pillow lava flows occur in underwater vents and look like rolling globs of lava.
The pasty rock often solidifies into rounded formations dubbed pillow lava. Marine microorganisms soon colonize the pillow-lava surfaces, where they exploit chemical energy to fuel their metabolism (SN: 11/15/03, p.
A pillow lava is a type of flow that forms only when magma erupts into water or wet sediment.
The seal must have originated in a massive outpouring of basalt onto the seafloor near the ridge axis, an eruption different in many ways from somewhat more classic modes of volcanism that lead to emplacement of pillow lava. The pillows, characterized by low electrical resistivity (about 10 ohm|center dot~meter) appear to constitute more than 75 percent of the lava pile at Site 504 and are, consequently, considered to be the main mode of oceanic crust emplacement there.
