Fig. 2From: Sr isotopic ratios of hydrothermal fluids from the Okinawa Trough and the implications of variation in fluid–sediment interactionsRelationship between Mg and Sr concentrations in hydrothermal fluids from the Iheya North Knoll, HAKUREI, JADE, Hatoma Knoll, and Yonaguni Knoll IV sites in the Okinawa Trough. Light blue stars indicate the value of seawater. Red lines are regression lines through all data and seawater for each site. No such line was drawn for the Yonaguni Knoll IV because of poor fitBack to article page
