Abstract

The East African passive margin resulted from complex reactivation of the ca. 600–500 Ma East African-Antarctic Orogen (EAAO). With the help of a large set of new thermochronological data (U-Pb titanite, Ar-Ar hornblende and biotite, as well as zircon, titanite and apatite fission-track analyses) we have modelled the tectono-thermal history of NE Mozambique from the late (Lower Palaeozoic) stages of the East African-Antarctic Orogeny to its transformation into a passive margin in the Mesozoic.
