The most common are the following: Basalt and gabbro are usually formed by volcanoes that have an oceanic crust origin, such as Hot Spot volcanoes such as the Hawaiian Islands. Andesitic rocks (Andesite) or Diorite are usually formed by subduction zone (strato-or compositive volcanoes) at convergent boundaries.Rhyolite (formed above ground-extrusive) and granite (intrusive-formed under ground and usually never reaches the surface under eruption conditions).ndesitic rocks (Andesite) or Diorite are usually formed by subduction zone (strato-or compositive volcanoes) at convergent boundaries.
