Composite volcanoes
No. Pahoehoe forms basalt.
That depends on the chemistry of magma the volcano erupts - Basalt, andesite, rhyolite etc. but Generically the rock coming out of a volcano is called lava rock (pahoehoe or aa) but one can also get pumice or ignimbrites.
Both pillow lava and pahoehoe lava have about the same composition and harden into a kind of rock called basalt.
Basalt is an igneous rock that is formed after a volcano erupts.
Basalt formations can be massive, encompassing many square miles. The mineral crystals which make up basalt require magnification to see.

Because of the large basalt rock formations in the area. These are extrusive volcanic flows (lava) from the early Tertiary Age,
The explorer found a basalt inside of a volcano.
The most abundant silicic volcanic rock is Basalt. This is a main hazardous and acidic effect of an explosive volcano. Please be careful when travelling to places with active volcano.
A flood basalt is not a volcano in and of itself. It is a large rock formation created by an extended period of intense volcanic activity.
Kilauea is made up of lava flows. Lava pours out of the volcano in thin sheets, building up the volcano over time.
