Fig. 3From: Relationship between tectonism and desertification inferred from provenance and lithofacies changes in the Cenozoic terrestrial sequence of the southwestern Tarim BasinTypical grain size distributions of representative samples. Measured data is indicated in red, and the three identified sub-components are indicated in blue, yellow, and green. The 64–500 μm fraction used for the ESR and CI analyses in this study corresponds to the coarsest sub-populationBack to article page
