5. The southern Kerguelen Plateau is one of the earliest known products of the extensive Kerguelen plume magmatism with dredge samples dated at 109 to 115 million years old (1), and rocks from ODP drill-holes range from 112 to 85 Ma [M. Storey, M. S. Pringle, M. F. Coffin, J. Wijbrams, Eos 77, W123 (1996)]. The Ninetyeast Ridge is the hotspot track from the northward migration of India from >83 to 43 Ma [(32); R. A. Duncan, Proc. Ocean Drill. Prog. Sci. Res. 121, 507 (1991)]. Broken Ridge and its conjugate, the northern Kerguelen Plateau, were erupted from 88 Ma until 43 Ma (32), when rifting was initiated along the Southeast Indian Ridge (SEIR) between Broken Ridge and the northern Kerguelen Plateau [J.-Y. Royer and D. T. Sandwell, J. Geophys. Res. 94, 13 (1989)]. The Kerguelen Islands are the most recent of the Kerguelen Plume volcanism from 39 to 0.04 Ma [(11); J. Nougier, in Antarctic Geology and Geophysics, R. J. Adie, Ed. (International Union of Geological Sciences, Series B-No. 1, Scandinavian Univ. Books, Oslo, 1972), pp. 803-808].

20. 188Os ranged from 0.10 to 0.44% (2σ), although replicate analyses (one was a separate aliquot from the same powder split and another from a separate powder split) agreed within ±0.5% and ±0.7%, respectively. Osmium standard runs were reproducible within 0.3% (2σ). Osmium concentrations were determined by fire-assay and isotope dilution and were reproducible at ±7% (2σ). Blank corrections for Os isotopic composition and concentrations were less than the uncertainty of counting statistics in most cases and only applied when the correction was greater than the counting error. Rhenium concentrations were measured on separate powder splits by inductively coupled plasma-mass spectrometry at the Lamont-Doherty Earth Observatory. Reported Re concentrations are not blank-corrected (procedural blank was ∼10 to 20 ppt), and counting statistics were 0.6 to 3.2% (2σ). Thus, most of the samples had negligible amounts of Re.
