  What Is the Mineral Composition of Andesite? |

  The mineral composition of andesite is largely plagioclase. Plagioclase is a silicate mineral that goes into forming many types of rock. Another mineral composition of andesite is biotite, which is another silicate mineral that's also a type of mica. Accessory minerals in andesite include quartz, hornblende, pyroxene, glass, garnet and ilmenite.

  Oceanic crust | geology |

  The topmost layer, about 500 metres (1,650 feet) thick, includes lavas made of basalt (that is, rock material consisting largely of plagioclase [feldspar] and pyroxene). Oceanic crust differs from continental crust in several ways: it is thinner, denser, younger, and of different chemical composition.

  What Is the Mineral Composition of Andesite? |

  Full Answer. Andesite is a finegrained, igneous rock that's formed out of lava flows. It's usually a blackishbrown or green color, especially if the rock contains a lot of glass. It is often found with basalt and sourced from the Pacific Ocean. It's also part of the crust of the planet Mars.

  Igneous rock composition and texture

  The composition of igneous magmas is directly related to where the magma is formed. Magmas associated with crustal spreading are generally mafic, and produce basalt if the magma erupts at the surface, or gabbro if the magma never makes it out of the magma chamber. It is important to remember that basalt and gabbro are two different rocks based purely on textural differences they are .
