Igneous metamorphic and sedimentary rocks hold the history of the earth and the materials that will be used to build its future. Rocks are an aggregate of one or more minerals held together by chemical bonds. It erodes into sediment and then gets compressed into a sedimentary rock. Feldspar and quartz are the most common minerals found in rocks.

Hence the study of metamorphic rocks provides an understanding of the pressure and temperatures deep within the earth s crust. Igneous and sedimentary rocks mainly undergo this change and become metamorphic rocks. Each kind of igneous rocks contains different minerals and has different structures. About 27 000 years ago lava flowed on top of the navajo sandstone forming black ropey basalt in snow canyon state park washington county.

The sedimentary rock becomes metamorphic with heat and pressure. From the terminology itself igneous means from fire or heat. Igneous rocks solidified from magma and lava. 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.

The existing rock type which undergoes a change is referred to as the protolith. Based on the rock formations there are three basic classes which include igneous sedimentary and metamorphic. Unakite is a metamorphosed granite composed of green epidote and pink orthoclase. Partial melt granitic type rocks are granitic gneiss which is a metamorphic rock.

Granite type rocks granitoids are abo. Then due to various conditions within the earth the existing rock was changed into a. The scientific study of rocks is called petrology. Igneous sedimentary and metamorphic.

Igneous sedimentary and metamorphic. Igneous rocks comprise about 95 of the total earth s crust. To aid in their study of the earth geologists group rocks into three categories based on their origin. Even the granites that form via metamorphism of sediments are igneous because they pass through a melting stage.

Each category is then further subdivided. All other types of rocks viz sedimentary and metamorphic originate from igneous rocks and therefore they are also called primary rocks. Igneous rocks formed when liquid magma or lava magma that has emerged onto the surface of the earth cooled and hardened. Based on the mode of formation three major groups of rocks are defined.
