What Volcanoes are made mostly by granitic lava?

Volcanoes primarily composed of granitic lava are typically classified as stratovolcanoes or composite volcanoes. These volcanoes are characterized by their steep profiles and explosive eruptions due to the high viscosity of granitic lava, which is rich in silica. Examples include Mount St. Helens in the United States and Mount Fuji in Japan. The granitic composition leads to the formation of thick, dome-like structures and can result in significant pyroclastic flows during eruptions.
