N2 - Forty outcrops of Lower Eocene chalks (Mor Formation) around Beer Sheva were examined for faulting. Ten well-exposed normal faults, with mean dip and strike of 39 ± 6° and 294 (N66°W) ± 28°, respectively, were found in four outcrops. The timing of fault movement is partly constrained by unfractured Lower Eocene chert nodules which follow some of the fault traces. Hence, the faults are interpreted to be the result of dynamic failure due to horizontal NNE-SSW compression during the Early Eocene. Horizontal compression is implied by analogy to descriptions of recent faulting caused by an earthquake in another location, local folding in the Lower Eocene, secondary fractures and flat and ramp structures associated with the investigated faults.
