Formation of Mugearite and Basaltic Trachyandesite


Formation of Basaltic Trachyandesite and Mugearite


Formation

Formation
Mugearite forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.   
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

Mugearite and Basaltic Trachyandesite Formation

Formation of rocks is a long process and hence, Mugearite and Basaltic Trachyandesite 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. Get to know all about formation of Mugearite and Basaltic Trachyandesite, composition of Mugearite and Basaltic Trachyandesite and their transformation.
