Both Ilmenite and titanomagnetite occur as primary minerals in Andesite and they occur both in phenocryst and in the groundmass. Garnet is a rare mineral found in some Andesite and the distribution of such Andesite is normally restricted to continental margins that contain pelitic sediments. Garnet occur as euhedral, usually between 1 and 2 mm, crystals.

Biotite, quartz, magnetite, and sphene are common accessory minerals. Alkali feldspar may be present in minor amounts. Classification of andesites may be refined according to the most abundant phenocryst. 2 For example, hornblende-phyric andesite indicates that hornblende is the principal accessory mineral within andesite. Formation of andesite

Andesite Homestead

2017-7-15  Andesite is an igneous, volcanic rock, of intermediate composition, with aphanitic to porphyritic texture. The mineral assemblage is typically dominated by plagioclase plus pyroxene and/or hornblende. Magnetite, zircon, apatite, ilmenite, biotite, and garnet are common accessory minerals. Alkali feldspar may be present in minor amounts.

Modification of the Composition of Andesite Raw Material

2019-11-6  The properties of andesite, a neutral or subalkaline medium volcanic rock, are reviewed. Using the example of andesite mined in Kamchatka, an analysis of the possibility of applying methods for modifying the composition of igneous rocks, which were developed at the Kurnakov Institute of General and Inorganic Chemistry, to the production of mineral fibers and stone casting has been made.
