1 Formation

1.1 Formation

Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.

Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

Gabbro and Quartzite Formation

Formation of rocks is a long process and hence, Gabbro and Quartzite formation sounds very interesting. According to the formation, all rocks are divided into :Igneous Rocks, Fossil Rocks and Metamorphic Rocks. Igneous rocks form by crystallization of magma or lava. The magma is made up of various components of pre-existing rocks which have been subjected to melting either at subduction zones or within the Earth's mantle. Igneous rocks are generally seen at mid ocean ridges or in intra-plate hotspots. Sedimentary rocks are formed when sediments accumulate gradually. As the sediments are buried they get compacted as more and more material is deposited on top. Eventually the sediments become so dense that they form a rock. Metamorphic rocks are rocks which once existed as igneous or sedimentary rocks but have been subjected to varying degrees of pressure and heat within the Earth's crust.
