How can LLD of a typical silica under-saturated magma (basanite / alkali olivine basalt) be described, like the Carmichael's paper (1964) on Thingmuli for oversaturated liquids?
Hi Sarah. If you want your liquid line of descent to be SIMPLE, then AFC will not do and you must seek out a paper about a differentiated AOB/basanite sill. Try Google Scholar with the term "differentiated alkaline basic sill". I'll try this myself in a moment or two. Bob
For another example, try: Beier et al 2006 "Magma Evolution of the Sete Cidades Volcano, Sao Miguel, Azores JOURNAL OF PETROLOGY VOLUME 47 NUMBER 7 PAGES 1375–1411 2006 doi:10.1093/petrology/egl014
