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, felsic, igneous rock. Granite has a medium to coarse texture, occasionally with some individual crystals larger tha â¦ n the groundmass forming a rock known as porphyry.Granites can be pink to dark gray or even black, depending on their chemistry and mineralogy. Outcrops of granite tend to form tors, and rounded massifs.ranite is hard to scratch with a fingernail.   2. Basalt is formed from lava that cooled rapidly, so it has a fine-grained texture. Its mineral grains are so tiny that they can be seen only through a microscope. It may be black or dark green. It contains the minerals feldspar and olivine.
