More DetailsThe geological definition of granite is "any plutonic rock in which the mineral quartz makes up 10 to 50 per cent of the felsic components, and the ratio of alkali to total feldspar is between 65 and 95 per cent." Commercially, any holocrystalline quartz-bearing plutonic rock is generally included in the granite group.
More DetailsNew way to find granite/diorite/andesite. [Terrain] Mountains are part of the update too, and now I''m bringing some attention to it. Granite, diorite and andesite mountains should be a thing, since they are beautiful and are a way to put some value for these materials. The generation should be like a normal mountain, just replacing stone.

More DetailsTonalite is an igneous, plutonic rock, of felsic composition, with phaneritic texture. Feldspar is present as plagioclase (typically oligoclase or andesine) with 10% or less alkali feldspar. Quartz is present as more than 20% of the rock. Amphiboles and pyroxenes are common accessory minerals.. In older references tonalite is sometimes used as a synonym for quartz diorite.
More Details· Highlights. Deep learning models were created for the classification of images of granitoids, which are the most abundant plutonic rocks in the Earth''s crust.

More Details· Unlike granite, diorite has no or very little quartz or alkali feldspar. Unlike gabbro, diorite contains sodic—not calcic—plagioclase. Typically, sodic plagioclase is the bright white variety albite, giving diorite a high-relief look. If a dioritic rock erupted from a volcano (that is, if it is extrusive), it cools into andesite lava.
