| 520 | |b The lithostratigraphic and biostratigraphic review of the Late Cretaceous/Paleogene (k/pg) boundary in the Al Uwayliah area with a comprehensive stratigraphic correlation is the aim of this study. The Upper Cretaceous rocks of Wadi Al Dukhan Formation at Al Uwayiliah area is in general composed of microcrystalline dolostone and calcitic dolostone. The Wadi Dukhan Formation at surface exposures in Cyrenaica is of Maastrichtian age as indicated by rudistid pelecypoda. The Maastrichtian age is confirmed from subsurface sections (Well B7 and U2-6) based on larger foraminifers. The Underlying Paleocene deposits, on the other hand, are represented by the Landenian Al Uwailyah Formation which is cropping out near al Uwaiyliah village is made of chalky limestone alternating with foraminiferal wackestone. It has been dated Late Paleocene the Landenian age based on Globorotalia pseudomenardii Zone and Globorotalia angulata Zone. However, the Uwailyah Formation was assigned to the Planorotalites pseudomenardii Zone. Hence, the Al Uwayliah Formation represents only the late Paleocene (Landenian) with complete absence of Danian and Selandian age making unconformable contact (=11 Ma.) with the underlying Wadi Dukhan Formation. Elsewhere, at al Athrun area the stratigraphy is completely different as Apollonia Formation unconformably overlain the Athrun Formation with angular unconformity (=10 Ma. Missing) in response to severe tectonism. | ||
