英文摘要	Chronology of Neoproterozoic volcanosedimentary successions remains controversial for many regions of the Arabian-Nubian Shield, including the Dokhan Volcanics of NE Egypt. New U-Pb zircon SHRIMP ages have been obtained for 10 silica-rich ignimbrites and two subvolcanic dacitic bodies, mapped as Dokhan Volcanics, from the North Eastern Desert of Egypt. Crystallization ages range between 592 +/- 5 and 630 +/- 6 Ma (Early Ediacaran). Apparently, the late consolidation of the Arabian-Nubian Shield was accompanied by the evolution of isolated volcanic centres and basin systems which developed during a period of approx. 40 Ma, independently in space and time and probably under changing tectonic regimes. The obtained age data together with other previously published reliable ages for Dokhan Volcanics suggest two main pulses of volcanic activity: 630-623 Ma and 618-592 Ma. Five samples contain inherited zircons, with ages of 669, 715-746, 847 and 1530 Ma, supporting models that North Eastern Desert crust is mainly juvenile Neoproterozoic crust. (C) 2010 Elsevier B.V.
