Abstract

Key points The Sr isotopic ratios of hydrothermal fluids from the Okinawa Trough are exceptionally high. The enrichment of 87Sr at Yonaguni Knoll IV cannot be explained without the influence of terrestrial clay minerals in sediments. High Sr isotopic ratios are a common feature of sediment-associated hydrothermal systems.
