Geologists uncover evidence of a missing Late Cretaceous magmatic arc in northwestern Iran

Mountains preserve evidence of ancient oceans, moving continents and tectonic processes that have shaped Earth over millions of years. Later deformation, erosion and burial, however, can obscure important parts of this geological record. An international research team led by Istanbul Technical University (ITU) has identified evidence of a previously unrecognized Late Cretaceous continental magmatic arc in northwestern Iran.
