Figure 2

142 million years of Canarian seamount volcanism in 40Ar/39Ar age spectra.

Apparent ages from sequential single-crystal total fusions and step-heating analyses are plotted against cumulative 39Ar fractions. Accepted analyses and plateau steps are black. Box heights are ±2σ. Inverse-variance weighted mean ages are statistically valid, as indicated by low Mean Square Weighted Deviates (MSWD) and sufficient Probabilities (>0.05)37,38. Mean age errors are 2σ and include uncertainties in J-values. Note breaks in age scale. See text and Supplementary Information S3 and S4 for more data and diagrams.
