Nice table of "Igneous rocks classified by silicon dioxide content", but tonalite is missing (apparently it belongs between diorite and granodiorite). Otherwise as well, the table's content doesn't correlate well with the article. I know that silicon dioxide isn't necessarily the same thing as quartz, so I don't expect an exact correspondence of percentage, but an explanation of the relationship seems essential.
