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 an igneous rock composed of mostly two minerals: quartz and feldspar. It is an intrusive rock, meaning that it crystallized from magma that cooled far below the earth's surface.Its name is derived from the Latin word 'granum', which means 'grain', a reference to the easily-seen minerals in the rock.ranite contains mostly quartz and orthoclase feldspar; other minerals make up less than half of the rock. The magma that crystallizes into granite likely forms in the upper mantle or lower lithosphere, where other rocks partially melt. Granite is used in buildings and some granite is mined for rare elements.
