(Table T1) Volatile and minor element concentrations in basaltic glasses from Leg 187 sites

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).于187航次采自澳大利亚南极断裂带（Australian Antarctic Discordance, AAD）的玄武质熔岩，为全球洋中脊扩张体系这一特殊区域的地幔动力学、地幔熔融及地壳形成过程提供了珍贵的研究记录。本文报道了海底枕状玄武岩未蚀变玻璃边部的溶解态挥发分（H₂O、CO₂、S及Cl）浓度。本次分析的玻璃样品来自187航次的12个站位，涵盖太平洋型（站位1153、1154、1158及1160）与印度洋型（站位1152、1156、1157、1159及1161）两类同位素类型（Christie等，2001，doi:10.2973/odp.proc.ir.187.2001；D. Christie，私人通信，2003）。针对本次数据的详细解读，以及与AAD区域近期轴部印度洋型及太平洋型玄武岩玻璃的对比研究，将在后续论文中发表（L.V. Danyushevsky等，私人通信，2003）。
