Origin of Silicic Magmatism at the Katla Volcanic Complex, South Iceland

Abstract The Katla volcano is a bimodal caldera complex within Iceland's basalt‐dominated Eastern Volcanic Zone. To unravel the petrogenesis of silica‐rich rocks from Katla, we provide new δ18O values for almost 60 basaltic, intermediate, and high‐silica eruptive rocks, including a number of pa...
