摘要：AbstractA total of 103 surface sediment samples collected from the water depth range of 15–3300 m along Vijaydurg-Karwar stretch of central west coast of India were analyzed for foraminiferal content. Relict benthic foraminiferal assemblage was noted within 50–135 m water depth. The relict benthic foraminiferal assemblage that includesAmphistegina,OperculinaandAlveolinellain sediment samples within the water depth of 85–135 m indicates presence of coral reef at this depth during Early Holocene. The presence of barnacle fouling on Relict foraminifera at 60–90 m confirms the paleo-shoreline. The shallow depth zone is characterized by presence of agglutinated relict foraminifera. The agglutinated forms indicate freshwater influx, which eventually increased the sea level and subsequently deteriorated the paleo-coral reef.Graphical abstractDisplay OmittedHighlights► Relict benthic foraminifera from 85 to 135 m water depth along West Coast of India. ► Foraminifera indicates presence of Early Holocene coral reef. ► Freshwater influx deteriorated the paleo-coral reef.
