The statistical Study of Jointsarround 16 Tishreen lake dame region in ALKabir
ALShimali river basin showed the presence of several main groups of Joints with
directions NE-SW _ NNE-SSW, NW-SE, E-W.
- Group NE-SW: showed correspond to with the fau
lt structures of same directions
which are normal and reversal faults and distributing geographically 1n Lattakia Kallas
fault zone. Also it showes correspond to with the axis of folds of same direction, thus
explained as longitudinal joints within these folds
- Group NW-SE: showed correspond to with faults structures of same direction.
which are left and right lateral strike slip faults, Spread over the entire study area. and it
may(diagonal)shear group within the folds of NE-SW axes.
- Group E-W:correspond to with normal faults structures.
Joints study in Skhaba region shows the existence two joint directions, principal dominant
NW-SE Joints from extension origin upper Cretaceous age, unrelated and older than faults
in studied area statistically, the presence of Calcareous filling in
the joints that is supported
the extension origin in the first phase. Secondary NE-SW joints from Miocen-Pliocen in
age, and from extension origin ,related to the formation of faults, most of them contain thin
iron crust in secondary phase.
