A few other methods have been applied, but of these only C-14, thermoluminescence and electron spin resonance proved to be quite successful as well.

Uranium series dating seems to be a most reliable and rather frequently used technique to determine the formation age of such speleothems.

" The Shuiyindong Gold Mine hosts one of the largest and highest-grade, strata-bound Carlin-type gold deposits discovered to date in Southwestern China.

The outcrop stratigraphy and drill core data of the deposit reveal Middle–Upper Permian and Lower Triassic formations.

This study aimed to verify the occurrence of two distinct hydrothermal events at the Shuiyindong, based on Sm–Nd isotope dating of the fluorite and calcite.

For this purpose, rare-earth element (REE) concentrations, Sm/Nd isotope ratios, and Sm–Nd isochron ages of the fluorite and calcite were determined.
