WebThe upper zone is located at a depth of 6–10 km, and the lower one occurs at 14–16 km. At a depth of 10–14 km they are separated by an inversion layer with V p=6.2–6.3 km/s. The lower inversive zone is characterized by a monotonic increase in the velocity from 6.3 to 7.2 km/s to the bottom of the crust. WebJun 9, 2024 · The hydrocarbon fluids in UHP clinoenstatites and retrogressed β-Mg 2 SiO 4 strongly suggest their source from the mantle transition zone or base of the upper mantle. We conclude that the peridotitic diamonds precipitated from C-H fluids during mantle upwelling beneath the Neo-Tethys Ocean spreading center.
