  2. Tonalite–trondhjemite–granodiorite - Wikipedia

    en.wikipedia.org/wiki/Tonalite–trondhjemite...

    For example, Coastal Batholith of Peru consists of 7–16% gabbro and diorite, 48–60% tonalite (including trondhjemite), and 20–30% granodiorite, with 1–4% granite. [22] These TTG rocks in continental arc batholiths may partially originate from the magma differentiation (i.e. fractional crystallisation ) of the subduction induced mantle ...

  3. Granitoid - Wikipedia

    en.wikipedia.org/wiki/Granitoid

    Granite rock hand-sized sample. A granitoid is a generic term for a diverse category of coarse-grained igneous rocks that consist predominantly of quartz, plagioclase, and alkali feldspar. [1] Granitoids range from plagioclase-rich tonalites to alkali-rich syenites and from quartz-poor monzonites to quartz-rich quartzolites. [2]

    The granitoid rocks are mainly potassic granite and were derived principally from reworked older (3.1–2.8 Ga) gneiss. [3] During the Paleoproterozoic, island-arc terrane associated with the Colorado orogeny accreted to the Wyoming Craton along the Cheyenne belt, a 500-km-wide belt of Proterozoic rocks named for Cheyenne, Wyoming.

    The great majority of Yosemite Valley's widening, for example, was due to joint-controlled rockfall. In fact, only 10% of its widening and 12% of its excavation are thought to be the result of glaciation. [3] Large, relatively unjointed volumes of granite form domes such as Half Dome and monoliths like the 3,604 ft (1,098 m) high El Capitan.

  6. S-type granite - Wikipedia

    en.wikipedia.org/wiki/S-type_granite

    The S-type Strathbogie Granite crops out in the Strathbogie Ranges of Australia. A hand sample from the Strathbogie Granite has a porphyritic texture with larger crystal of grey quartz, called phenocrysts, set in a finer grain matrix of quartz and feldspar. The darker, prismatic, phenocrysts in this sample of the Strathbogie Granite are cordierite.

    Granodiorite (/ ˌ ɡ r æ n oʊ ˈ d aɪ. ə r aɪ t, ˌ ɡ r æ n ə ˈ-/ GRAN-oh-DY-ə-ryte, GRAN-ə-) [1] [2] is a coarse-grained intrusive igneous rock similar to granite, but containing more plagioclase feldspar than orthoclase feldspar. The term banatite is sometimes used informally for various rocks ranging from granite to diorite ...
