    Andesite ( ˈændəzaɪt ) [1] is a volcanic rock of intermediate composition In a general sense, it is the intermediate type between silica -poor basalt and silica-rich rhyolite It is fine-grained (aphanitic) to porphyritic in texture, and is composed predominantly of sodium-rich plagioclase plus pyroxene or hornblende [2] Andesite is the extrusive equivalent of plutonic diorite
