Where does pillow basalt form? Pillow basalt is a volcanic igneous rock that forms when lava of basaltic compositionis erupted underwater. The rapid cooling of the lava by cold water on all sides forms the pillow-shaped bodies, which can then break open and extrude more of the hot lava from inside. hydro thermal vents ... 48 terms. 3. In general, the more felsic the composition (richer in silica - resulting in an Intermediate composition ), the larger the pillows, due to the increase in viscosity of the erupting lava.
