Stable Isotope Study of Precipitation in Jinan

Yong Sen Wang, Zhenghe Xu

Abstract

The 8 water samples of rain in Jinan were collected in the summer. A local meteoric line (LMWL) was got. And the derived equation is that δD = 8.19δ18O+ 8.89, which represents the local precipitation line. The precipitation water in Jinan is characterized by the high mean deuterium excess (d=10.9‰). The isotopic compositions in Xi’an were also be collected. And the local meteoric line in Xi’an is that δD=6.97δ18O+3.01, with a low slope The slopes of the meteoric line were different for the two sites, which can reveals some evaporation information about the precipitation.
