In classification of igneous rocks, the mineralogical constitution and the degree f crystallization of the mineral should be considered. Igneous rocks have infinite variety so it is of great help to classify them into groups of similar properties. Igneous rocks are plutonic in reference to their origin or as a holocrystalline in reference […]
