(a) Correlation between the depth to major seismic reflectors and resonance frequency. Dots represent ambient noise measurements. Red points correspond to the top of the Judea group, blue to the base of the Kurkar group, and orange to the base of the Bet Guvrin formation. (Qishon graben). Rectangles represent simulation results (figures are station numbers and peaks marked in Fig. 9). For stations 3–12 the lowest frequency peak is plotted against the depth to the top of the Judea group (black). In stations 6–10, where the Kurkar group overlies the Avedat or Mount Scopus groups, the frequency of the second lowest peak is plotted against the depth to the top Mount Scopus or Avedat groups. (b) Average shear-wave velocities of the sedimentary section as a function of its thickness.

 Section AA′ from Gvirtzman et al. (2005) showing the north Sharon graben, which preserves a complete section of the Mount Scopus and Avedat groups and a 600–100 m thick Bet Guvrin (lower Saqiye) section. The faults bounding that graben are detected seismically and mapped in the top Judea Group structural map (Fleischer &amp; Gafsou 2003). They are buried by the undisturbed Quaternary Kurkar Group and possibly also by the Pliocene Yafo Formation that wedges out west of the Pardes Hanna well. Stratigraphic correlation with a nearby outcrop (section BB′) indicates that faulting probably occurred during the Miocene (upper part of the Bet Guvrin Formation).

Photos show faults that rupture Neogene and Quaternary units. The locations of these images are presented in Figure 3. (A) The relations between the early–middle Miocene Hordos Formation and the major southern boundary fault of the Faria Graben. Note that while the Eocene Avedat Group and the lower part of the Hordos Formation are faulted, the upper part of the Hordos Formation is un-faulted and developed on-lap relations with the fault scarp. Also, the upper calcrete crust of late Miocene–early Quaternary age is not faulted or deformed. These observations indicate that the Faria Graben has been tectonically inactive since the middle Miocene.

Spectral ratios of the Fourier series shown in Figure 8. Black curves show the amplification of simulated horizontal acceleration relative to the no-basin models. Solid circles are the resonance peaks related to the seismic reflectors formed by the top Judea group and the base Kurkar-top Avedat or Mount Scopus groups (frequency-depth correlation in Fig. 10). Blue curves are the ratios between the horizontal and the vertical components of the basin simulation (H/V). Red curves are H/V spectral rations from ambient noise measurements conducted at nearby sites. Differences and similarities between curves are discussed in the text. Note that the large amplification of long periods in Station 13, resulting from division of two very small numbers, is misleading. It represents very weak surface waves that leak from the basin edge into the bedrock and are totally missing in the no-basin model.

Abstract Ashalim maze cave, and neighbouring caves in the NW Negev Desert, Israel demonstrate hypogene karst features. These features are shown to have developed as a result of the mixing of two types of groundwater flowing in opposite directions within two tiers of Cretaceous rock aquifers. The stable isotope composition indicates that the lower Kurnub sandstone aquifer was recharged over far-field Nubian Sandstone outcrops in the vicinity of the Precambrian basement outcrops of the Sinai Desert, which belongs to the Afro-Arabian dome. The water flows northward and rises into the Judea carbonate aquifer through deep faults. A similar hydrogeological system is inferred for the speleogenetic period of Ashalim Cave. Dewatering of the cave occurred in the Pliocene due to regional uplift. This is indicated by the first vadose speleothems, dated to the late Pliocene (3.1 Ma). This was followed by surface denudation, which breached the cave and formed the present entrance.
