Figure F27. Leg 187 site locations in relation to seafloor isochrons (after Vogt et al., 1984). Sites are color coded according to the mantle domain interpreted from onboard Zr-Ba data based on Figure F26A. Sites with two colors indicate that two mantle types were sampled. Colored lines are ship tracks for Leg 187 (blue) and the two site survey cruises aboard the R/V Melville (red and green).
