Abstract:
Site 1159 was located in Zone A, and was the youngest seafloor drilled during Leg 187 and southernmost site along the transect designed to locate possible occurrences of Indian-type mantle beneath western Zone A. Hole 1159A was the only hole drilled; it produced 7.96 m (28.7% recovery) of aphyric basalt with a few pieces of hyaloclastite breccia with interstitial sediment. The basalts were assigned to a single unit of moderately altered aphyric pillow lava with alteration halos along piece margin and veins The Ba and Zr contents of the glasses indicate a Pacific-type mantle reservoir beneath this site. This site was the fourth Pacific site of five sites drilled in western Zone A, reinforcing the conclusion that the Indian/Pacific mantle boundary is closely associated with the eastern margin of the depth anomaly. Data tables and figures are found at the end of the chapter.(LEL)
