Jericho - Petrologic Studies
Rb-Sr(phlogopite) of 172+/-2Ma (Jurassic)
lithosphere - asthenosphere at depths of 190km below Jericho
conductive geotherm of approx. 40 mW/m2
variable suite of xenoliths - eclogite, pyroxenites, wherlites etc.
Re-Os isotopic dating indicates that the Archean lithosphere has been perturbed in the Proterozoic
Wherlites indicate a “magmatic event” circa 450Ma
