[edit] Wrong Info
Andesite is a fine-grained, extrusive igneous rock with anhedral or euhedral crystals. It's an intermediate rock and it has a medium color. It occurs when lava or magma from an andesite volcano cools underground. It usually has 55 to 65% total silica content, along with plagioclase feldspar(andesine and oligoclase), pyroxene, amphibole and biotite mica.

- OK. Whoever that was, wrong, wrong, wrong. How can it be an extrusive rock which cools underground? Really. Rolinator 05:14, 27 December 2005 (UTC)
[edit] Silliness
Don't know much about geology, but I have a feeling that this article has suffered from some juvenile sabotage:
The water and initial tylerisstupid slab melts rise into the mantle wedge... The following part looks odd, too, unless it is some technical code unfamiliar to me:
Ultimately, the resultant composition of andesite and intermediate magmas is the result of fractional crystallisation, assimilation, partial melting cbnvcnvcnnbvcnbvc and contaminaton by the subducted slab.
