87Sr/86Srplant ratios of modern samples from Vanuatu.
Symbols represent short-rooted plants (SRP), medium-rooted plants (MRP), and deep-rooted plants (DRP). The vertical dotted line delineates between sampling locations on Efate Island and Malakula. The solid horizontal line designates the average 87Sr/86Sr ratio for modern seawater and the two dashed lines represent the high and low 87Sr/86Sr ratios of oceanic basalt. The sampling location is detailed by the number in parentheses in Figures 2 and 3.
