The western side of the anticline forms two minor folds trend northeast and southwest. The northern part of the area, where the main faults exist, is more faulted than the southern part. Majority of the faults extended for 5-6 km and have throws less than 50 m. Figure 4.1 shows the distribution of faults and their directions. Joints Joints are well developed in the dolomite and limestone especially in Lower Beit Kahil, Hebron and Bethlehem formations.
Joints are often up to one meter wide at the surface.
Chalky and marly rocks are less affected with joints and solution channels than limestone and dolomite. The presence of joints and karst caves make the formations good aquifers. The soil classifications and references to major vegetation were adopted from the document entitled, The Soil of Israel , 1976. This type of soil association covers approximately 817 hectares of the district. It is found in areas with smooth to gently sloping topography.
