摘要

The Huize ore field, which is the most famous high-grade Mississippi Valley-type Zn-Pb ore field in China, consists of the Kuangshanchang and Qilinchang deposits. The Sm-Nd isotopic compositions of gangue calcite were analyzed to constrain the timing of mineralization. Eight calcite samples from the No. 6 orebody in the Qilinchang deposit have Sm and Nd concentrations of 1.82-25.93 and 15.25-79.02 ppm, respectively, and yielded an age of 225 ± 9.9 Ma with epsilon Nd =-10.6 and MSWD = 0.13.
