Possible non-melted remnants of subducted lithosphere: experimental and geochemical evidence from corundum-bearing mafic rocks in the Horoman Peridotite Complex, Japan

Morishita, Tomoaki; Arai, Shoji; Green, David

Description

We report experimental results and whole-rock trace-element characteristics of a corundum-bearing mafic rock from the Horoman peridotite complex, Japan. Coronitic textures around corundum in the sample suggest that corundum was not stable in mafic rock compositions during the late-stage P-T conditions recorded in the complex (P < 1 GPa, T < 800°C). Based on the experimental results, corundum is stable in aluminous mafic compositions at pressures of 2-3 GPa under dry conditions, suggesting that...[Show more]
