The Central African Shear Zone (CASZ) (or Shear System) is a wrench fault system extending in an ENE direction from the Gulf of Guinea through Cameroon into Sudan.[1] The structure is not well understood. As of 2008, there was still no general agreement about how the individual shears along the lineament link up.[2]
