Hydrous equilibrium crystallization experiments were conducted on two boninitic melt compositions, low-Si boninite (LSB) and high-Si boninite (HSB), from the Izu-Bonin-Mariana (IBM) fore-arc to constrain the evolution of magma storage conditions and differentiation during subduction initiation. Experiments were performed at temperatures between 1020 and 1220 °C and at pressures of 200 and 400 MPa. Additionally, 14 natural boni...

The Izu–Bonin–Mariana volcanic arc is situated at a convergent plate margin where subduction initiation triggered the formation of MORB-like forearc basalts as a result of decompression melting and near-trench spreading. International Ocean Discovery Program (IODP) Expedition 352 recovered samples within the forearc basalt stratigraphy that contained unusual macroscopic globular textures hosted in andesitic glass (Unit 6, Hole...
