A test of deep seismic reflection profiling across the central uplift or metamorphic belt of the Qiangtang (羌塘) terrane, Tibetan plateau, provides a first image of the crustal structure. Complex reflection patterns in the upper crust are interpreted as a series of folds and thrusts, and bivergent reflections in the lower crust may represent a convergence between the Indian and the Eurasian plates.
