Petrogenesis of Orangeites and Kimberlites
Many years of study have not resulted in general agreement concerning the petrogenesis of continental alkaline rocks. Unfortunately, petrologists, acting from a stance of promoting their own particular bias, be it geophysical, experimental, geochemical, or tectonic, have devised contradictory models for a given magma type. Once introduced, such models are commonly promoted by their originators without impartial reflection on all aspects of the problem or consideration of competing hypotheses.
