Abstract:
This data report provides a systematic documentation of the low-temperature alteration associated with the formation of a volcanic-rifted margin by the quantification of alteration effects and vein mineralogy and distributions in basalts recovered on Leg 152 (Larsen, Saunders, Clift, et al., 1994, doi:10.2973/odp.proc.ir.152.1994). Basaltic rocks from Holes 917A and 918D have been investigated to provide a quantitative description of the extents of recrystallization and secondary mineral abundance resulting from low-temperature alteration and weathering. Only limited descriptions of alteration and secondary mineral distributions were undertaken on board ship during Leg 152, and the data presented here provide an essential complement to the shipboard logs of the limited amount of basalt recovered during Leg 163 from Sites 988, 989, and 990 (Duncan, Larsen, Allan, et al., 1996, doi:10.2973/odp.proc.ir.163.1996).
