Field photos showing Early Miocene normal faults in the Wulan and Guide basins in the eastern Qaidam and West Qinling, and lava sheet in the Hoh Xil. (A) A normal fault controlling basal sedimentation of Lower Miocene unit in the Wulan basin, with a small depositional wedge thickening toward the fault. Width of view ∼20 m. (B) A normal fault separates the Guidemen from Garang units in the Guide basin, which is covered with the upper Garang fine-grained layer. Width of view ∼80 m. (C) Various-scale normal faults in the Garang sequence of the Guide basin. People for scale. (D) Early Miocene lava sheet in the distance, which overlies the Yaxicuo Formation and undergoes little deformation. View in the background 500 m wide.
