Granite is an intrusive, felsic rock, which may be produced by partial melting or fractional crystallization. Explain how these processes can produce felsix magmas from more mafic parent magmas.

Question

Since this is not my area of expertise, I searched Google under the key words "fractional crystallization granite" to get these possible sources:

I hope this helps. If not, you can try your own searches using other key words in your question. Thanks for asking.

Thank you
