Basalt not 100% but most of it. About 10% is other rocks. I hope that helps
Most igneous rocks are made up of silicate minerals, such as quartz, feldspar, mica, amphibole, and pyroxene. These minerals are rich in silicon and oxygen and form the bulk of the composition of igneous rocks.

No, igneous rocks are, as they are created by hardening lava, and most of the planet earth is lava
Igneous rock is by far the most common rock of the crust.
Basalt and granite are the most common types of rocks that make up igneous rocks. Basalt is a fine-grained volcanic rock, while granite is a coarse-grained intrusive rock.
Igneous rocks and most metamorphic rocks, of an igneous origin.
Igneous rocks are formed from the cooling and solidifying of magma. The resulting rock can be instrusive (magma cooling within the crust) and extrusive (lava cooling on the surface). The most common kind of rocks are Granite (intrusive) and Basalt (extrusive).
Most igneous rocks have a relatively homogenous mix of minerals which are interlocked.
Igneous rocks are the most common type of rocks on earth.
Sedimentary rocks are the result of broken down igneous rocks so they cover up most of igneous rocks.
== Grain size. Most intrusive igneous rocks will have visible crystals. Crystals in most extrusive igneous rocks are not easily visible.
Granite is the rock that makes up most of the continental crust. It is a coarse-grained igneous rock that is formed through the slow cooling of magma beneath the Earth's surface. Granite is composed mainly of quartz, feldspar, and mica minerals.
