1 I-type Granites. 2  I-type granites are granites considered to have formed by melting of an original igneous type source. 3  These are generally metaluminous granites, expressed mineralogically by the absence of peraluminous minerals and the absence of peralkaline minerals, as discussed below. wide variety of igneous rocks occur in the continental lithosphere, a reflection of its heterogeneous nature compared to oceanic lithosphere. In addition, because the continents are not subducted and are subject to uplift and erosion, older plutonic rocks are both preserved and accessible to study.
Granite is a common and widely occurring type of intrusive, ingenious rock formed from Lava. Most Granite is located throughout the continental crust, usually at a depth of 1.5 km and up to 50 km. Granite has a medium to coarse texture, occasionally with some individual crystals larger than the ground mass forming the rock. This makes Granite quite rich in depth and color variation within each piece. Granites come in shades of Pink, Blue, Green and Gold to Gray, and even Black. Granite is very Hard and Tough, with an average Density of 2.75 g/cm3.
