No mafic layer in 80 km thick Tibetan crust

No mafic layer in 80 km thick Tibetan crust

Crustal doubling in Tibet and the Himalayas by underthrusting of the Indian plate is thought to require the presence of a mafic layer above the Moho. Here, the authors present seismic data which shows that the middle Lhasa Terrane has very low velocity (V p  < 6.7 km/s) throughout the 80 km thick...
