Shield volcanoes are typically formed from basaltic lava flows, which are low in silica content and very fluid. This type of lava allows for the gradual buildup of wide, gently sloping volcanic cones characteristic of shield volcanoes.
Shield volcanoes are primarily composed of basaltic rock, which is a type of volcanic rock that is low in silica content and high in iron and magnesium. This type of rock creates gently sloping shield volcanoes due to its low viscosity and ability to flow easily during eruptions.
Granite
The dominant rock type in ocean crust is basalt, which forms from solidified lava. In continental crust, the dominant rock type is granite, which forms from the cooling and solidification of magma beneath the Earth's surface.
Oceanic crust is primarily made up of basaltic rock, which is dense and rich in iron and magnesium. Continental crust is composed mainly of granite and other lighter silicate rocks, which are less dense than basalt.

Igneous.
All three rock types are found in continental crust, with a preponderance of granitic type igneous rock.
The continental crust is composed largely of granite.
