As nouns the difference between andesite and andesine

is that andesite is a class of fine-grained intermediate igneous rock, of volcanic origin, containing mostly plagioclase feldspar while andesine is sodium calcium aluminum silicate, ($Na\_xCa\_xAlSi\_3O\_8$), a plagioclase feldspar, the third member of the albite-anorthite solid solution series. Found in fine-grained andesite lavas; crystals are rarely seen.
