Tierra del Fuego Igneous and Metamorphic Complex is a geological basement complex known from boreholes in northern Tierra del Fuego . ^[1]^[2] The complex is made up of foliated igneous rocks of Cambrian age including orthogneiss . ^[1]^[2] It underlies unconformably the Jurassic Tobifera Formation . The protoliths of Cordillera Darwin Metamorphic Complex are unrelated to Tierra del Fuego Igneous and Metamorphic Complex despite present-day proximity. ^[1]
