Lake Qinghai and the adjacent lakes were generally low and aeolian sands were widely distributed in the northeastern Tibetan Plateau during the early Holocene. Ostracod δ18O records from Lake Qinghai cannot be used to reflect the strength of the East Asian summer monsoon or the intensity of monsoon precipitation. Moisture and precipitation at Lake Qinghai and its environs began to increase in the early Holocene, reached their maximum during the middle Holocene, and decreased during the late Holocene.
