Mineral Abundance In Granodiorite

  • Geology - rocks and minerals

    Granodiorite Granodiorite is an intrusive rock, intermediate in composition between diorite and granite.Although often similar in appearance to diorite or granite, it has a higher quartz content than diorite, and a higher mafic mineral content than granite. It is commonly produced in volcanic arcs, and in mountain building where it emplaces as large batholiths in mountain roots.

    Granodiorite, medium- to coarse-grained rock that is among the most abundant intrusive igneous rocks. It contains quartz and is distinguished from granite by its having more plagioclase feldspar than orthoclase feldspar; its other mineral constituents include hornblende, biotite, and augite.The plagioclase (andesine) usually forms twinned crystals, sometimes wholly encased by orthoclase.

    03-06-2019· Igneous rocks are those that form via the process of melting and cooling. If they erupt from volcanoes onto the surface as lava, they are called extrusive rocks.By contrast, Intrusive rocks are formed from magma that cools underground. If the intrusive rock cooled underground but near the surface, it is called subvolcanic or hypabyssal, and often has visible, but tiny mineral grains.
