List of sample information used in this study_ All samples were collected from the southeast margin of the Tibet Plateau, which is located in the junction between the first and second ladder of China terrain_ The quartz extracted from bedrock (MN05) was sampled 10 mm beneath its surface; DTZG03 was sampled at 0_7 m beneath the surface deposits; MN06 was collected from the modern floodplain_ MN05 and MN06 were collected from the same river drainage with unitary lithology of granite_
