| Klyuchevskoy Volcano, Kamchatka, U.S.S.R., is the most rapidly erupting island arc volcano in the world producing lavas with a narrow range in SiO;The ;Aqueous, two-phase, fluid inclusions (5-10 ;Relatively high flux rates due to recharge of more primitive basaltic magmas inhibit fractionation to more siliceous compositions. Rapid eruption rates facilitate passage of these lavas that might otherwise be obscured in less productive volcanic systems. |
