What type of lava do strato volcanoes have?

The textbook answer would be andesite. In reality stratovolcanoes are highly variable and have been known to erupt all of the types of lava observed on modern earth from basalt to rhyolite, sometimes from the same volcano. One stratovolcano even erupts unique carbonatite lava.

Then then will change in shape and form but basalt will always have the same chemical composure as if it had a different one it would be a different rock.
