| 英文摘要 | The Songshan tin deposit is located in Lancangjiang tin belt in the Sanjiang Tethys metallogenic domain, which is related to Lincang granite complex. The tin orebodies occur as skarn, veins, and greisen. The ore minerals are composed of cassiterite, pyrrhotite, chalcopyrite, arsenopyrite, and pyrite. There has no available age dating published in the area, which restricts the understanding of the genesis of the deposit. The paper reports the U-Pb isotope dating of cassiterite using the method of in-situ LA-SFICP-MS at the Songshan tin deposit. The results show that the Pb-207/(206)pb -(238),U-206/Pb concordia ages of cassiterite from the skarn ore and quartz -vein ore are 76.6 +/- 1. 5Ma and 79.6 +/- 3.6Ma, respectively. These ages indicate that the Sn mineralization formed in Late Cretaceous at the Songshan tin deposit, which is quite different from the age of the Lincang granite, which emplaced in the Triassic. Combined with other published age data, it concluded that the Sn mineralization in the Late Cretaceous occured in the Songshan deposit and its adjacent areas. The next exploration target should focus on the contact zone between granite and wall rocks, as well as the faults that occur in the granite. |
