The isobaric interference, 36S, is a main problem in AMS measurement of 36Cl. The SO42− ion exists in the natural environment with an amount compared with the chlorine concentration. The chemical procedure should have a powerful capacity to remove

The gabbro xenoliths are inferred to form at (224 ± 524) Ma by means of Sm-Nd dating, which reflected the intrusive age or crystallization age of gabbric melts. This event indicates that the region transformed from stable platform stage into Mesozoi

Scheelite Sm-Nd and quartz Ar-Ar dating were accomplished for the Woxi Au-Sb-W deposit in western hunan. The results show that the Sm and Nd concentrations of scheelite are relatively high, and Sm/Nd ratios are usually high and variable. In the 147Sm

The research on Samarium-Neodymium isotope systematics of hydrothermal calcites from the Xikuangshan antimony deposit, Central Hunan, places precise timing constraints on the Sb mineralization in this area. It is revealed that the Xikuangshan deposit
