Basaltic lavas recovered from the Australian Antarctic Discordance (AAD) during Leg 187 provide a valuable record of mantle dynamics, mantle melting, and crustal formation in this unusual region of the global mid-ocean spreading system. In this paper, we report dissolved volatile (H2O, CO2, S, and Cl) concentrations of unaltered glass rims from submarine pillow basalts. The analyzed glasses come from 12 Leg 187 sites that include both Pacific Ocean (Sites 1153, 1154, 1158, and 1160) and Indian Ocean (Sites 1152, 1156, 1157, 1159, and 1161) isotopic types (Christie, Pedersen, Miller, et al., 2001, doi:10.2973/odp.proc.ir.187.2001; D. Christie, pers. comm., 2003). Detailed interpretation of these data and a comparison with recent on-axis Indian- and Pacific-type basaltic glasses from the AAD will be presented elsewhere (L.V. Danyushevsky et al., pers. comm., 2003).
