The K-Ar ages from the basaltic rocks of Leg 134 range from Miocene to Holocene (Table 1). Samples were selected in consultation with shipboard scientists; choice of the material from the forearc sites was very limited and confined to clasts. There was a wider choice of material from the sill at Site 833 in the North Aoba Basin.
