About Andesite Stone
Andesite is common in most of the world's volcanic areas. Andesites occur mainly as extrusive lavas on land and, to a lesser extent, as dikes and small plugs. Not only the Andes, where the name was first applied to a series of lavas, but most of the cordillera (parallel mountain chains) of South, Central and North America consist largely of andesites. The same rock type occurs in abundance in volcanoes along practically the entire margin of the Pacific Basin. The volcanic eruption of andesite along the margins of the Pacific Basin is related to subduction of the continental
plates.
Andesite is mainly grey in colour, fine-grained and usually porphyritic with coarse crystals of plagioclase and pyroxene in a very fine-grained matrix. Compared with basalt, it can be vesicular and/or amygdaloidal. Andesite is composed of plagioclase, pyroxene, hornblende, minor alkali feldspar, biotite, magnetite, ilmenite and quartz (< 10 %). The very fine texture of andesite is a result of rapid cooling on land.
