Cryogenian-Ediacaran U-Pb geochronologic database of East African Orogen

The metamorphic and magmatic rocks produced during mountain building is crucial to constrain geodynamic processes. We compiled zircon U-Pb ages between 1.1-0.52 Ga from Neoproterozoic metamorphic and magmatic rocks from Tarim, the Arabian–Nubian Shield, Oman, Mozambique belt, NW India, Madagascar, and the Lhasa terrane. The vast majority of ages in this compilation are from felsic to mafic intrusive or extrusive rocks, or their metamorphic equivalents. Northern Tarim is characterized by Andean-style subduction-accretion from 900-650 Ma which closely parallels the tectonic environment in the ANS, MB, central and southern Madagascar. Several rift-related provinces developed in South Tarim, Congo-São Francisco, West Africa and the Lhasa block during the 900-880 Ma interval on many of these blocks indicating large-scale breakup.
