Abstract
Australian-Antarctic Ridge (AAR) is an extension of eastenmost SE Indian Mid-Ocean Ridge. Jan. 2013, Korea Polar Research Institute (KOPRI) dredged basaltic rocks from the axis and the off-axis seamounts of the AAR using Icebreaking research vessel Araon. Collected basalts contain fine subhedral or anhedral olivine, plagioclase, and pyroxene phenocrysts, while the off-axis seamount basalts contain more olivine phenocrysts compared to the axis basalts. We studies melt inclusions hosted in the olivine phenocrysts in the seamount basalt by EPMA and LA-ICP-MS. We fused and characterizing a halogen-bearing basaltic glass as well, for an external SRM for SIMS microanalysis of halogens in natural basaltic glass and melt inclusions.
