  • The Bowen Reaction Series in Geology

    2019-2-2 · The Bowen reaction series is a description of how magma ''s minerals change as they cool. The petrologist Norman Bowen (1887–1956) carried out decades of melting experiments in the early 1900s in support of his theory of granite. He found that as a basaltic melt slowly cooled, minerals formed crystals in a definite order.
