Fourteen sample from the stratigraphic interval (1330-1600m.) in the borehole KH5/1 were studied palynoogically. The samples yielded well preserved and diversified palynomorphs except one sample at depth (1330m.) was barren.
Identification of (54) species of acritarchs belong to (29) genera and (16) species of Chitinozoans belong to (9) genera, (16) species of miospores belong to (13) genera and (6) species of Scolecodont belong to (4) genera was the conclusion of this study.
Comparision with similar palynomorphs in different parts of the worlds indicates clearly Upper Silurian (Ludlow) age for the samples studied. The Palynomorphs and especially the acritarchs reveal that the studied section was deposited in near
