WebbThe so-called imperial porphyry on the left is a decorative building stone originating in Egypt. It is an altered andesite or dacite that contains millimeter-sized white feldspar phenocrysts. The porphyritic basalt in the middle contains plagioclase phenocrysts up to several centimeters long. WebbClassification of andesites may be refined according to the most abundant phenocryst. For example, if hornblende is the principal phenocryst mineral, the andesite will be described as a hornblende andesite . Andesitic volcanism [ edit] Andesite lava typically has a viscosity of 3.5 × 10 6 cP at 1,200 °C (2,190 °F).
