Palynological Analysis of cutting samples from Well: A1-177/01, Murzuq Basin

Abstract

Playonological study have been utilized in order to define age and depositional environments of the 
penetrated sections of the well A1-177/01, which belongs to Chevron Libya Limited, located in the South Eastern 
Margin of Murzuq Basin. The study based on selected one hundred and four cutting samples, and despite of 
difficulties caused by heavy caving and reworked palynomorphs, palynological recoveries in general was good in 
the upper half of the studied section.
Microscope investigations revealed moderately rich to poor assemblages consisting mainly of miospores, 
few marine acritarches and chitinozoans, recovered from the studied samples enabled to erect six distinctive 
palynological assemblages. These assemblages range from Early Silurian to Early Carboniferous in age. The 
ages assigned to these assemblages have been determined by comparing the palynomorphs assemblages with 
similar assemblages recorded from Paleozoic sequences in other nearby wells in Murzuq Basin, Ghadamis Basin, 
North East Libya region, South east Libya (Al Kufrah Basin) and also from other parts of old Gondwana region. 
Paleoenvironmental interpretation is based on interpreted lithological and palynological criteria.
