| Mass Independent Oxygen Isotope Fractionation in Nitrate Deposits of the Turpan-Hami Area, Xinjiang |
| With the development of analyzing and measuring techniques and Mass independent isotope fractionation methods,the application of mass independent oxygen isotope fractionation has been used in an increasingly wider field,and has become an important method for studying the evolution of the early earth and the interaction between different circles on the earth.Nitrates and sulfites compose a few existent minerals that have mass independent oxygen isotope fractionation.The authors measured oxygen isotope composition of nitrate and sulfite minerals in the Turpan-Hami Area of Xinjiang, and the results show that there exists obvious mass independent oxygen isotope fractionation in nitrates and slight mass independent oxygen isotope fractionation in sulfites. This paper provides evidence that long-term atmopspheric deposition makes up the sources of superlarge nitrate deposits. |
