Characteristics of δ18O and δD in precipitation and its water vapor sources in the upper Urumqi River basin,Eastern Tianshan

Shui kexue jinzhan, 2013
The stable isotopes characteritics of hydrogen and oxygen in precipitation is an important aspect of the regional isotope hydrologic cycle. The variations of δD and δ18O values in event-based precipitation samples are analyzed. The samples were collected
