| Abstract: | The ore deposit consists of 2 veined ore bodies,which are separately in the greisenization zone of the first（V1） and second（V2） stage granite of Late Yanshanian.The V1 is the semi-weathering Nb-Ta deposit,whereas the V2 is the original Sn deposit.The paragenetic minerals include wolframite and scheelite.The genesis is close related with the structure and intermediate-acid intrusive rock. |
