The following is a list of rock types recognized by geologists.There is no agreed number of specific types of rocks. Any unique combination of chemical composition, mineralogy, grain size, texture, or other distinguishing characteristics can describe a rock type.

List of Top 16 Metamorphic Rocks Geology. The dominant types of metamorphic rocks derived from igneous and sedimentary rocks are listed in the tables below This is a massive, hard compact to fine grained metamorphic rock developed in contact with large igneous intrusions (by contact metamorphism) Under the microscope a characteristic mosaic texture can be recognized
12/01/2015· The three types of rocks. It’s the first thing you learn in a geology class — very briefly the three types of rocks are: Igneous — they form from the cooling of magma deep inside the earth
Types of Rocks. Geologists classify rocks into three main groups: igneous rock, sedimentary rock, and metamorphic rock. Metamorphic Rock is formed by heat and pressure from other rocks. Depending on how the rock formed, rocks can be igneous, sedimentary, or metamorphic. Igneous Rock
As per Wikipedia, “Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means “change in form”. The original rock (protolith) is subjected to heat (temperatures greater than 150 to 200 °C) and pressure (1500 bars), causing profound physical and/or chemical change.
25/01/2018· Metamorphic rocks can be divided on the basis of their metamorphism regional, thermal, hydrothermal, and fault zone metamorphism. Regional metamorphic rocks are found in the mountainous regions, and are developed in accordance to the
Type of rainfall common near large water bodies formed as a result of convective rising and cooling of moist air. The major rocks are metamorphic rocks e.g. marble in parts of Machakos and schist and gneiss in parts of Kitui. The lava in the vent which is hard due to slow cooling is exposed forming a stump of rock e.g. Peaks of Mt . Get Price
Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form". The original rock is subjected to heat (temperatures greater than 150 to 200 °C) and pressure (100 megapascals (1,000 bar) or more), causing profound physical or chemical change.The protolith may be a sedimentary, igneous, or existing metamorphic rock.
15/11/2018· Examples of Metamorphic Rocks. Metamorphic rocks are less common than sedimentary and igneous rocks, but still make up approximately 12% of rocks at the surface. Some of the most common types of metamorphic rocks are: Slate: Slate is a metamorphic rock that forms under relatively gentle heat and pressure conditions applied to shale, a
Rocks are formed due to chemical compositions & erosion that takes place on the earth. Igneous, sedimentary & metamorphic are the different types of rocks. Rocks of Archaean system, Dharwar system & Cuddapah system are types of rocks in India
Metamorphic grades. The different groups of minerals, or assemblages, that crystallize and are stable at the different pressure and temperature ranges during regional metamorphism distinguish distinct metamorphic grades, or faces. The grades are usually named for the dominant minerals or colors that identify them (Figure 1).

This change to metamorphic rock takes place very deep within the earth's crust. The process of this change does not melt the rocks like you would think, but instead what it does is literally transform them into rocks that are more dense and compact. Metamorphic Rocks Examples. Below are a few examples of the most popular types of metamorphic rocks.

Home » Rocks. Rocks: Igneous, Metamorphic and Sedimentary Rocks hold the history of the earth and the materials that will be used to build its future.
ADVERTISEMENTS: Metamorphic changes of orignal rocks into new types of rocks can happen in the following ways:-1. Contact or Thermal Metamorphism 2. Hydrothermal Metamorphism 3. Regional Metamorphism 4. Burial Metamorphism 5. Plutonic Metamorphism 6. Impact Metamorphism. Type # 1. Contact or Thermal Metamorphism: This type of metamorphism
Types of Metamorphic Rocks. Metamorphic rock fall into two categories, foliated and unfoliated. Most foliated metamorphic rocks originate from regional metamorphism. Some unfoliated metamorphic rocks, such as hornfels, originate only by contact metamorphism, but others can originate either by contact metamorphism or by regional metamorphism
The table below shows examples of common metamorphic rocks. Clicking on the name of the rock will bring up a larger picture and a description of the rock type in a new window. Remember these rocks are formed under extreme heat and pressure. Learn more about metamorphic rocks
