الملخص EN

The study and statistical analysis of (19) valleys in the Gebel al Akhdar region in northeastern Libya were conducted.

North.

south, east.

west, northeast.

southwest, northwest.

southeast in each rank was determined separately in each valley and in the entire region, and the direction of any valley and the direction of the joints within or along it was measured, and in some cases the direction of the nearest joint to the valley was taken.

In addition to the above, the direction of the valleys of each order in each formation in each valley separately, and then in the entire region, was determined, after that the relationship between the valleys and the direction of the joints measured in the formation was determined.

Statistical methods were used to analyze the data of this study, which consisted of coefficients V Cramer’s which depend on x2 .

By analyzing the data of this study, the researcher concluded that the main trend of the valleys in the region is northeast - southwest, and that there is a relationship between the trends of the valleys and the directions of the joints and faults in the region.

The value of the relationship between the trends of the first-order valleys and the directions of the joints in the Al-Bayda and Al-Abraq formations is greater than in the Apollonian and Darnah formations.
