What Does BABB Stand For?

BABB stands for Back Arc Basin Basalt

BABB, or Back Arc Basin Basalt, refers to a specific type of volcanic rock that forms in back arc basin settings, typically associated with tectonic plate boundaries. These basalts are characterized by low viscosity and are typically rich in iron and magnesium, resulting from partial melting of the mantle due to extensional tectonics. BABB formations provide valuable insights into geological processes such as crustal extension, magma generation, and the dynamics of oceanic and continental interactions in regions surrounding active subduction zones.
