4.1. Ze 'elim Gully (ZA-2) Chronology from Kagan et al (2011)

[28] Twelve organic debris samples from the 10.7 m deep Ze'elim (ZA2) outcrop were measured. Their calibrated radiocarbon ages range from 1056 to 1276 A.D. to 4843–4583 B.C. (95% probability). A deposition model is calculated for the top 8 m of this section. Model ages of samples are given in Table 2. The more western ZA1 section (~100 m away) was dated by Ken-Tor et al. [2001a, 2001b] and revised by Agnon et al. [2006]. In the Ze'elim Gully previous studies infer the sedimentation rate to range between 0.28 to up to ~1.3 cm/yr [Ken-Tor et al., 2001a; Agnon et al., 2006; Neumann et al., 2007] reflecting the additional detrital clastic sediments that are more abundant in the fan delta environment. The lower sedimentation rate (0.3 +/- 0.03 cm/yr) at the ZA2 section of Ze'elim (current study) reflects the proximity of this section to the lacustrine environment. The ZA2 outcrop is interpreted to show continuous deposition according to the age depth model (Figure 4), as opposed to the numerous unconformities at the more landward ZA1 outcrop. However, at ZA2 there is the possibility of short hiatuses compensated by additional sediments at sandy facies which therefore are not manifested in the age-depth diagram.
