What Does OIB Stand For?
OIB stands for Ocean Island Basalt
OIB, or Ocean Island Basalt, refers to a type of volcanic rock primarily found on oceanic islands that are formed from molten material originating from the Earth's mantle. OIB is characterized by its unique geochemical composition, which differs from that of mid-ocean ridge basalts. This rock type is typically associated with hotspot volcanic activity and provides valuable insights into mantle dynamics, island formation, and the geological history of oceanic regions. OIB is significant in studies of petrology, volcanology, and geochemistry.
