Pahoehoe flows
Fluid basaltic lavas such as rhyolite and dacite typically form thick short lavas namely lava spines, lava domes or coulees.
Composite cone volcanos are the most common.. Shielding and other types are results from a divergent boundary.
Basaltic, low viscosity lava would form lava tube caves.
Lava flows cool to form extrusive igneous rock. Most lava flows consist of basaltic lava, cooling to form a dark rock called basalt. Some, however, may consist of andesite or, rarely, rhyolite and similar lavas.

Lava plateaus form when fluid basaltic lava flows out of fissures.

They are formed where over time by continual layers of lava building up. They are normally a raised area of land that forms tablelands or flat topped hills. These can go on for hundreds-thousands of kilometres fluid basaltic flows out....
Basaltic Lava
Basaltic magma usually forms a black rock.
basaltic lava can form a'a, pahoehoe, or pillow lava.
