Rocks are naturally occurring solid masses or aggregates of minerals there are three major types of rocks as sedimentary rocks igneous rocks and metamorphic rocks. It is formed when bodies of magma cool and harden deep below the earth. Igneous sedimentary and metamorphic.

Composed of quartz potassium feldspar and mica. Each kind of igneous rocks contains different minerals and has different structures. Are responsible for changing these two types of rock into metamorphic rock. The main difference between gneiss and granite is that gneiss is a type of metamorphic rock whereas granite is a type of igneous rock.

The granite melts into lava then cools becoming igneous. Granite is a coarse or medium grained rock that is rich is quartz and feldspar.

Igneous rocks sedimentary rocks and metamorphic rocks are the major three rock types in the earth s crust geologist made this classification based on the geological process that formed these rocks. To aid in their study of the earth geologists group rocks into three categories based on their origin. All other types of rocks viz sedimentary and metamorphic originate from igneous rocks and therefore they are also called primary rocks.

Each category is then further subdivided. Sedimentary rock becoming metamorphic. Even the granites that form via metamorphism of sediments are igneous because they pass through a melting stage. Most of the solid surface of our planet ro ughly 70 is represented by sedimentary rocks but if you go deep enough beneath the earth s surface there are plenty of igneous and metamorphic r.

About 27 000 years ago lava flowed on top of the navajo sandstone forming black ropey basalt in snow canyon state park washington county. Composed of feldspar and quartz.

Partial melt granitic type rocks are granitic gneiss which is a metamorphic rock. It is distinguished from granite because it does not contain quartz.

The sedimentary rock becomes metamorphic with heat and pressure.
