Latite Porphyry

Sometimes alternatively referred to as trachyandesite, latite is an igneous rock that typically occurs as porphyry, which is characterized by the presence of large phenocrysts in an extremely fine-grained matrix. The conspicuous crystals within the rock vary somewhat, but the groundmass is typically comprised of augite and orthoclase feldspar.
