WebAt 10 kbar when 4 wt % of water was added to the system the biotite melting reaction occurred below 800°C and produced garnet + amphibole + melt. At 15 kbar the melting reaction produced garnet + amphibole + melt with 2 wt % added water. At 20 kbar the amphibole occurred only at high temperature (900°C) and with 4 wt % added water.

WebFigure 4.2. 1: Normal L. Bowen. The most important aspect of Bowen’s Reaction Series is to notice the relationships between minerals and temperature. Norman L. Bowen (1887-1956) was an early 20th Century geologist who studied igneous rocks. He noticed that in igneous rocks, certain minerals always occur together and these mineral assemblages ...
