Stratovolcanoes, also called composite volcanoes are generally not made of basalt. While they may occasionally produce basalt, much of their material is andesite or dacite.
Shield volcanoes will erupt basaltic lava. Cinder cones erupt basaltic lava or basaltic andesite lava. Stratovolcanoes often erupt andesite lava, but may erupt basaltic or rhyolitic lava and all intermediate types as well.
Oceanic volcanoes usually release basaltic lava. Basaltic lava is low in silica content, which makes it less viscous and allows it to flow easily and travel long distances before solidifying. This type of lava is common in underwater volcanic activity due to the melting of basaltic oceanic crust.
Shield volcanoes are fed by basaltic magma.
Massive gently sloping volcanoes built of successive basaltic lava flows are called shield volcanoes. Examples of shield volcanoes include Mauna Loa in Hawaii and Mount Etna in Italy. These volcanoes are characterized by their broad, low-profile shape and the relatively peaceful eruptions of fluid lava.
Mafic, usually basaltic lava.
Fissures usually erupt basaltic lava.
Shield volcanoes are composed mostly of layers of basaltic lava flows.
Yes!
They produce basaltic lava.

A cinder cone has basaltic lava, which has a fairly low viscosity.

Basaltic lava (low in silica).
Mafic, usually basaltic lava.
Composite volcanoes typically erupt with a mixture of lava types, including both viscous lava (andesitic or rhyolitic) that can lead to explosive eruptions, as well as more fluid lava (basaltic) that can flow long distances. This combination of lava types is what gives composite volcanoes their steep-sided profile.
