Pleistocene and Holocene formations in Andaman including the Ritchie's Archipelago were examined. Based on hthology and age the Neill West Coast Formation is emended and redesignated as Neill Formation. A new lithounit, the Chidyatapu Member is proposed here with its type locality and relationship with the underlying Limestone Member. Preliminary Petrographic observations assign biocalcarenite facies to the Chidyatapu Member.

Based on hthology and age the Neill West Coast Formation is emended and redesignated as Neill Formation. A new lithounit, the Chidyatapu Member is proposed here with its type locality and relationship with the underlying Limestone Member. Preliminary Petrographic observations assign biocalcarenite facies to the Chidyatapu Member.
