Quaternary rise of the Sedom diapir, Dead Sea basin

摘要: Mount Sedom is the surface expression of a salt diapir that has emerged since Pleistocene in southwestern part Dead Sea basin. Milestones uplift history its inception were deduced from angular and erosional unconformities, thickness variations, caprock formation, chemistry isotope composition lacustrine aragonite, cave morphology, precise leveling, satellite geodesy. Thickness variations overburden observed transverse seismic lines suggest signifi cant growth may have initiated only after this exceeded ~2400 m Late Pliocene. The formation es arrival depth to dissolution level between 300,000‐100,000 yr B.P. During period later, unconformities upper near are attributed piercing diapir. Rapid solution rock parts inundated by Lake Lisan ca. 40,000 inferred Na/Ca ratios aragonite their relation δ 13 C. On mountain itself, older (70,000‐43,000 B.P.) Formation missing. top preserved sediments covered alluvial must been deposited when elevation was not higher than 265 below sea (mbsl) at 14,000 present these 190 mbsl indicates an average rate ~5 mm/yr over past yr.
