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. Granite is an intrusive, igneous stone usually found in the continental plates of the Earthâs crust. Igneous stones are mainly formed through volcanic material underneath the Earthâs surface, or liquid magma that has cooled and solidified.ranites are primarily composed of mica, feldspar and quartz, though additional minerals and trace elements give the stone a stunning array of possible colors. Graniteâs hardness and durability make it optimal for heavy-duty uses, such as flooring, countertops and vanities.
