Figure F44. Depth profiles of Mg/Ca, Sr/Ca, K/Mg and K/Ca, and Li/Mg and Li/Ca. JDF = values observed at Juan de Fuca Ridge flank, representing basement fluid. SW = seawater values. Mg/Ca and K/Ca displays diffusion between seawater and basement fluids. Sr/Ca values are larger than what is observed at Juan de Fuca Ridge flank, suggesting a strong influence of recrystallization taking place. Li/Mg and Li/Ca ratios are similar to the Mg/Ca profile.
