Noble gas isotopic signatures in thermal waters of the Dead Sea Transform, Israel
Noble gas isotope composition (especially helium) in thermal waters from different areas along the Dead Sea Transform in Israel reveals local intrusions of volatile gases and heat flux from the mantle into the crust. The distinct 3He/4He ratios in the atmosphere, crust and mantle enable one to …
