WebBowen’s Reaction Series describes temperatures at which different common silicate minerals change from liquid to solid phase (or solid to liquid). Petrologist Norman Bowen (1887-1956) conducted decades of melting experiments to support granite theory in the early 1900s. He found that a basaltic meltdown slowly cooled, and minerals formed ... WebMinerals weather chemically when they react with air and water. In these processes some minerals dissolve and others combine with atmospheric components (mainly water, oxygen and carbon dioxide) to form new minerals. The specific reactions include solution, oxidation, hydration and hydrolysis. Solution: Carbon dioxide (CO 2) released from ...
