Abstract:
K-Ar dates were obtained for three pillow basalt samples recovered from Site 608 (Samples 608-58-1, 103-109 cm; 608-59-1, 3-7 cm; 608-59-1, 48-53 cm). Reliable K-Ar dates cannot be routinely obtained for deep-sea igneous rocks, because they may be subject to inaccuracies related to seawater alteration (Seidemann, 1977, doi:10.1130/0016-7606(1977)88<1660:EOSAOK>2.0.CO;2) and/or the presence of excess radiogenic 40Ar (Dalrymple and Moore, 1968, doi:10.1126/science.161.3846.1132; Dymond, 1970, doi:10.1130/0016-7606(1970)81[1229:EAISBP]2.0.CO;2). Thus, the possibility that the samples dated in this study were subject to these sources of inaccuracy must be evaluated.
