Most lava forms a rock called basalt when it cools.
You would expect to find lava solidifying into basalt at the surface of a volcano or lava flow. Basalt is a common volcanic rock that forms when lava cools and solidifies quickly, usually in areas with high volcanic activity.
Basalt and igneous rocks were formed by what we would call magma/lava
It would form into the rock basalt, an extrusive, mafic, igneous rock.
basalt lava
the magma and lava in Surtsey are of alkali olivine basalt, which is the type of basalt found in Vestmannaeyjar (Westman Islands)
Pertaining to basalt; formed of, or containing, basalt; as basaltic lava.
Thin lava
cooling lava from volcanoes.
That would be the rock basalt.
Basalt is an igneous rock . . . it is pretty much hardened lava.
Basalt is formed when low-silica lava erupts from a volcano and later cools.
The magma and lava of Surtsey has a composition of alkali Olivine Basalt.
