lighter colored mineral components. Biotite and amphiboles often in the form of hornblende are more abundant in granodiorite than in granite, giving it a more...

Paleoproterozoic biotite granodiorite to granite that is known by geologist as the Mint Wash Granodiorite. The Mint Wash Granodiorite consists of medium...

Cathedral Peak Granodiorite (CPG) was named after its type locality, Cathedral Peak in Yosemite National Park, California. The granodiorite forms part of...

The Piégut-Pluviers Granodiorite is situated at the northwestern edge of the Variscan Massif Central in France. Its cooling age has been determined as...

monzonites, while granitic rocks dominated by plagioclase are classified as granodiorites or tonalites. Granitic rocks with over 90% alkali feldspar are classified...

Tonalite–trondhjemite–granodiorite (TTG) rocks are intrusive rocks with typical granitic composition (quartz and feldspar) but containing only a small...

Kuna Crest Granodiorite (also called Granodiorite of Glen Aulin), is found, in Yosemite National Park, United States. The granodiorite forms part of the...

with minor biotite as the only mafic mineral, named after Norway's third largest city, Trondheim. Tonalites, together with granodiorites, are characteristic...

City Granodiorite is a Silurian or Ordovician granitic pluton in Howard and Baltimore Counties, Maryland. It is described as a biotite granodiorite along...

darker than the western part. Sentinel Granodiorite is a light-gray and medium-grained biotite-hornblende granodiorite. The color index is normally about...

major intrusive suites within the Sierra Nevada. The granodiorite has large crystals of biotite, hornblende, and both feldspars — orthoclase and plagioclase...

gray, homogeneous, well-foliated granodiorite. Its modal composition is 57% albite-oligoclase, 27% quartz, 10% biotite, 4% muscovite, and 1% each epidote...

other Yosemite granites. Most black minerals are biotite. It is found west of Half Dome Granodiorite, both north and south, to a western limit near Cookie...

gneiss. Rock types include gneissic biotite-quartz diorite, hornblende-biotite-quartz diorite, and biotite granodiorite, with minor amounts of quartz monzonite...

potassium feldspar. Quartz is present at between 5 and 20% of the rock. Biotite, amphiboles and pyroxenes are common dark accessory minerals. Quartz diorite...

quartz-monzonite to biotite granodiorite, with rare garnet xenocrysts, per Martens 2009, p. 125, and exhibits relatively high muscovite-biotite ratio and small...

entirely of preexisting continental material and contains biotite-containing granodiorite and two-mica granite. However, the early metaluminous suite...

long. The river flows over the Newton River pluton of Carbonferous biotite, granodiorite and granite, which has been glaciated and also forms a rock arch...

Shannons Flat Granodiorite Shannons Flat Granodiorite is poor in xenoliths and is coarse grained. It was intruded after the clear Range Granodiorite. Tharwa...

sample CC-1 from the Cooma Granodiorite, Lachlan Fold Belt, Australia. In plane polarized light (PPL, Fig. 3a) the mineral biotite is light brown to "foxy"...
