It needs a lot of work, but after looking at the magma article, I think that this article is needed. It should cover the different types of setting in which igneous rocks are formed - e.g. Alkaline magmatism in rifts and Calk-alkaline magmatism at subduction zones, looking at the process rather than just the product.
