The Cordillera de la Costa belt, exposed for at least 600 km along the EW-trending coast of Venezuela, is a subduction mélange that contains fragments (knockers) of many rock types, notably eclogite and blueschist included in a matrix of mostly mica and graphite schist. The exhumation of the eclogite occurred in three stages. During the first stage (mid-Cretaceous), buoyancy forces drove the eclogite and its enclosing low-density matrix upward along the subduction zone from ∼75 to ∼25 km depth. During the second stage (Late Cretaceous), the mélange was severely fragmented by plate boundary–parallel stretching that caused the eclogite to ascend...
