Abstract: In 1991, the eruption of Mount Pinatubo, Philippines covered the South China Sea with a west-trending ash fan. The four layers studied in the central and eastern portions of the South China Sea reveal that the eruption has affected only the cores that were taken near the Island of Luzon. The study also shows that the major controls in the distribution of foraminifera in the study area include environmental stability, selective dissolution and water circulation.
