However, the difference between Hongge and Xinjie is also apparent, perhaps reflecting the source difference in the mantle. Relative to the Hongge intrusion the Xinjie intrusion is more depleted in Nd isotope ratio and enriched in REE and LILE. The Xinjie intrusion plots in the first quadrant in Sr-Nd diagram, which shows the Sr isotope-enriched and Nd isotope-depleted slightly feature. This indicates that the source of the Xinjie intrusion may had the mantle wedge signature.

The oxidation kinetics of depleted uranium was studied in pure oxygen pressure of 5 kPa at below 100°C by using spectroscopic ellipsometry. The relationship of the thickness of uranium oxide with time is measured. The results indicate that below 100°C in the initial period, the relationship between oxidation layer thickness and time is parabolic. The oxidation mechanism of depleted uranium is discussed and the active energy of depleted uranium at given experimental conditions is 87.165kJ/mol from calculation.
