What are metamorphic rocks?

Metamorphic rocks come from other types of rocks, but experienced significant changes from their original igneous rocks, sedimentary rocks or early metamorphic forms. Metamorphic rocks are formed when rocks are exposed to high temperature, high pressure, high temperature fluids rich in mineral matter, more generally a combination of these factors. Such conditions are located deep inside the earth or where the structure plate meets.

The metamorphism process does not melt the rock but instead turns them into a more compact and more compact rock. New minerals are produced by rearranging the mineral components or by reacting with fluid entering the rock. Depending on pressure and temperature, you can even turn previously degraded rocks into new types. Metamorphic rocks are often crushed, smeared and folded. Despite these unpleasant conditions, metamorphic rocks may not melt sufficiently or become igneous rocks.

Several metamorphic rocks - granite gneiss and biotite schists are two examples of strongly striped or leaves -. When pressure compresses flat or thin minerals in the rock and aligns them, leaves form. These rocks form a plate or sheet structure that reflects the direction in which pressure is applied.

Non-leaf metamorphic rock does not have a plate or sheet structure. There are several ways to make a rock without robes. Some rocks such as limestone are made of uneven or thin minerals. No matter how much pressure is applied, the grain will not line up. When high temperature igneous rocks penetrate into some existing rocks, another type of metamorphism and contact metamorphism will occur. Existing rocks are basically burned by heat, changing the mineral structure of the rock without increasing pressure.

When a human feels many calories, it sweats. When rock receives heat and pressure, it changes. Metamorphic rocks begin with another type of rock, such as igneous rocks and sedimentary rocks, as well as different metamorphic rocks. The process of creating a new rock is degenerate - you can think of these rocks as deformers! Since all the rocks are formed by various minerals grouped together in different ways, it can be confusing to distinguish them. In a simple rule of thumb, igneous rocks are formed from rocks that melt completely in the magma and then cool. Sedimentary rock consists of rocks and animal bones. These parts are adhered, like corrosion, by a process that is usually connected to water.

Metamorphic rock is the result of other rock conversion. Rocks exposed to high temperature and high pressure change their original shapes and shapes and become metamorphic rocks. This shape change is called degradation. These rocks are usually formed by partial melting and recrystallization of minerals. Gneiss is a common metamorphic rock formed by the high pressure contained in the original rock and partial melting of minerals. 3. Rocks may be an important source of minerals Sedimentary rocks or their foundation structures are mainly used for construction of civil engineering, houses, roads, tunnels, canals, etc. Geologists study the geological characteristics of metamorphic rocks as their crystallinity provides valuable information about the temperature and pressure within the Earth's crust.
