Which of the following is not an example of Metamorphic rock?

🔑Key Points:
Dolomite is a sedimentary carbonate rock.
Metamorphic Rocks
-Metamorphic rocks are rocks that have been changed from their original form by immense heat or pressure.
-They are formed when physical and chemical changes occur to igneous, sedimentary, or other metamorphic rocks.
-Metamorphic rocks are almost always harder than sedimentary rocks.
-They are generally as hard and sometimes harder than igneous rocks.
-They form the roots of many mountain chains and are exposed to the surface after the softer outer layers of rocks are eroded away.

• Foliated metamorphic rocks:
-These rocks are produced by exposure to heat and pressure which makes them appear layered.
-Phyllite and gneiss are examples of foliated metamorphic rocks.
Non-foliated metamorphic rocks: 
-These rocks don’t have layers.
-Marble and quartzite are examples of non-foliated metamorphic rocks.
Examples of Metamorphic Rocks : gneiss, quartzite, marble, schist, soapstone, and phyllite

🔴Additional Information::
– Igneous rocks are formed from solidified magma or lava.
-Magma is thought to be generated within the layer of partially molten rock underlying Earth’s crust at a depth below about 60 kilometers (40 miles).
-Lava is liquid magma on the Earth’s surface, and the solidified rock is formed by cooled lava.
-Some examples of igneous rocks are Granite, gabbro, basalt, etc.
Sedimentary rocks 
-They are formed from deposited and lithified mineral material.
-Fossils are generally found in sedimentary rock. Among the three major types of rock.
-Fossils are most commonly found in sedimentary rock.
-Mechanically formed — sandstone, conglomerate, limestone, shale, loess, etc. are examples;
-Organically formed — geyserite, chalk, limestone, coal, etc.
-Chemically formed —chert, limestone, halite, potash, etc.
