Answer is Earth crust.
The Earth crust is composed of many different types of rocks. It is mainly composed of about 95% igneous and metamorphic rocks, 4% shale, 0.75% sandstone, and 0.25% limestone. However, most of those rocks originated as either granite or basalt. The continental crust has an average composition of a medium to siliceous igneous rock, whereas the oceanic crust has an average composition of a low silica igneous rock.
