The timing of rifting-related magmatism in the Levant margins: U-Pb dating of zircons from deep boreholes in the coastal plain of Israel Conference Paper uri icon

abstract

  • Abstract The Levant basin, at the easternmost Mediterranean, formed during the opening of the NeoTethys. Whereas other Tethyan basins were later consumed during Alpine orogenesis, the Levant basin preserves its early history recorded by rifting-related subsidence and magmatism. While the Permian to Jurassic subsurface extensional structure along the Levant SE margins (coastal Israel) was reconstructed in detail, the scope and timing of igneous activity are not well known. A 2.5 km thick, mostly basaltic sequence, penetrated by the Atlit-1A borehole and named'Asher Volcanics', was shown to accumulate within a deeply buried fault-bounded NNE trending basin. Previous K-Ar and Ar-Ar dating and biostratigraphic considerations constrained the age of Asher Volcanics and consequently the activation of a Tethyan rift in the Levant to early to middle Jurassic times …
