Triassic and Creataceouse Palynomorphose from WellA2-045 /01 Offshore Libya

iassic and Cretaceous palynomorphs have been recovered from twenty three ditch cutting samples of borehole A2-054/01 located in the most northern part of Sirt Basin (Offshore), Libya.
Microscope investigations revealed moderately rich assemblages consisting only miospores in the Triassic section and mixed palynomorphs (dinocysts, miospores & algae) in the Cretaceous section. The recovered palynomorphose from the studied samples enabled to erect two distinctive palynological assemblages. These assemblages range from Early Triassic to Early Cretaceous in age. The ages assigned to these assemblages have been determined by comparing the palynomorphs assemblages with similar assemblages recorded from Mesozoic sequences in other nearby regions in Africa, North America and Europe.
Paleoenvironmental interpretation of the investigated sediments revelled that Cretaceous sediments were mostly deposited in shallow marine environment; other investigated rocks (Triassic) were deposited either in non-marine environment or in marginal marine environment
