WebbThe slower a magma cools, the larger crystals can grow. Named after geologist Norman L. Bowen (1887–1956), Bowen's reaction series allows geologists to predict chemical composition and texture based upon the temperature of a cooling magma. Bowen's reaction series is usually diagramed as a "Y" with horizontal lines drawn across the "Y." WebbAs the cooling rate was lowered, the weight fraction of magnetite increased together with …

Under the right conditions amphibole will form to biotite. Webb21 dec. 2024 · At the slowest cooling rates (10, 20, 50 °C/h), the ferrite appears to be almost entirely consumed by intermetallic formation.
