The quaternary geology and hydrology of Sede Zin, Negev, Israel Academic Article uri icon

abstract

  • Sede Zin is an alluvial plain undergoing severe erosion by Nahal (Wadi) Zin which flows towards the Dead Sea. During a portion of the Quaternary this wadi was part of the Mediterranean drainage system. The geological history since the end of the Neogene shows three main stages of deposition, from bottom to top:(1) Alluvial deposition, followed by weathering and formation of red loam and caliche (top Neogene, base Quaternary);(2) Deposition of silts and gravels (Lower to Middle Quaternary):(3) Deposition of loess (Upper Quaternary). The paleo-hydrological regima since the Neogene is understood to have been as follows: A humid to sub-humid Mediterranean climate at the end of the Neogene and base Quaternary was followed by another humid phase during the Lower and Middle Quaternary. This caused a hydroiogical regime in which gravel-laden streams flowed …
