Volcanic Sedimentary Rocks

Volcanic sedimentary rocks by (click here) are formed due to pyroclastic flows, volcanic breccias, impact breccias, and other processes which are rarely found and only occur in a few cases.

xtrusive.

Extrusive igneous rocks are rocks that occur above the surface of the earth’s crust. This is due to the process of melting magma in the mantle and crust. The process of forming this type of igneous rock is faster than intrusive igneous rock. Because the freezing process occurs above the surface of the earth.

Hipabissal.

Meanwhile, this type of hipabisal rock is formed by the process of rising and falling magma in the mantle or crust. These rocks are formed between volcanic and plutonic rocks.

Batuan Metamorf
Metamorphic rock is rock that has undergone a process of metamorphism. There are various types of metamorphic rocks, namely contact metamorphic rock, dynamo metamorphic rock and pneumatolistitic contact metamorphic rock. Here’s the explanation:

Contact metamorphic rock is a type of rock that undergoes a metamorphic process due to very high temperatures. This temperature comes from magma activity which causes changes in the shape and color of the rocks. Some examples of this metamorphic rock are marble, batholith, laccolite and sill rock. Dynamo metamorphic rocks are rocks that undergo metamorphosis as a result of high pressure and originate from endogenous forces for a long time, and are produced in the process of forming the earth’s crust and are influenced by endogenous forces. Pneumatolistitic contact metamorphic rock is a type of rock that undergoes a metamorphic process as a result of the influence of the gases present in the magma. This causes a change in the mineral chemical composition of these rocks.

Uses of Rock
Some of the types of rock that have been described above are familiar with our daily lives because many are used as building construction materials, or to beautify the appearance of the house. One type of rock that is often used as building construction is igneous rock. However, please note that not all igneous rocks can be used as part of the construction. Igneous rocks that are usually used as part of house construction such as andesite and lavastone. Other types of rock that are often used to support building construction are sedimentary rocks such as limestone, sandstone, and conglomerate.
