ResumoABSTRACT Zilberman, E., Greenbaum, N., Nahmias, Y., Porat, N., and Ashqar, L. 2008. Late Pleistocene to Holocene tectonic activity along the Nesher fault, Mount Carmel, Israel. Isr. J. Earth Sci. 57: 87-100. A paleoseismic analysis of the Nesher fault, a branch of the Yagur fault (the western segment of the Carmel tectonic system), was conducted east of Nesher, at a site where the fault trace crosses a small, abandoned alluvial fan. A 30-m-Iong and 2-4 m-deep trench excavated in the alluvial fan across the fault trace exposed a steeply northeastward-tilted late Paleocene to Early Eocene chalky-marly sequence on the northern side of the fault and a thick (more than 4 m) alluvial-colluvial sequence on its southern side. Two periods of tectonic activity accompanied by surface deformation were identified along the Nesher fault: I. Subsidence of a small basin south of the main fault manifested by colluvium that accumulated south of the fault trace and clay, unit I that accumulated in a small depression further to the south. The OSL age of unit 1 is 178
