Tefe is a buried circular structure in the Solimoes Basin in northern Brazil, identified
during oil exploration surveys using seismic methods. It has a diameter of 15 km, with a central
elevation 4 km wide, and shows all the morphological features of an impact crater. Tertiary sedimentary strata
350 m thick were deposited after the formation of the structure. It was formed in Cretaceous-Paleozoic sedimentary rocks and the deformation seems to reach the
basement at a depth of at least 3.2 km (Crosta A.P., Vasconcelos M.A.R., 2013).
