Tierra del Fuego Igneous and Metamorphic Complex
From Wikipedia, the free encyclopedia
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 Tobífera Formation. The protoliths of Cordillera Darwin Metamorphic Complex are unrelated to Tierra del Fuego Igneous and Metamorphic Complex despite present-day proximity.[1]
