The Hindu Kush seismic zone as a paradigm for the creation of ultrahigh-pressure diamond- and coesite-bearing continental rocks

Abstract:

Coesite eclogites and diamond-bearing ultrahigh-pressure (UHP) metamorphic rocks along ancient plate boundaries were mostly derived from quartz- and carbonate-bearing rocks originally formed close to the earth's surface. Their mineral assemblages and PT conditions require that they were subducted to depths of 90-130 km (27-40 kbar) and then brought back to the surface, still retaining evidence of their UHP formation. The geological record shows that continental-derived UHP rocks can be formed...
