英文摘要 | We report the first precise u-pb isotope data on cassiterite from the large xianghualing tin-polymetallic deposit in the central nanling district, south china. the results show that four separates from sample xf-51 have a relatively narrow range of pb-206/u-238 apparent ages, varying from 152 to 157 ma, and the three pb-206/u-238 apparent ages yield a weighted average value of 156 +/- 4 ma ( mswd=0.32). separates from two other cassiterite samples do not have sufficient radiogenic pb to generate a reliable pb-206/u-238 age. seven separates from the above three cassiterite samples define a well-constrained u-238-pb-206 isochron corresponding to an age of 157 +/- 6 ma ( mswd= 34). a comparison of the u-pb cassiterite ages with published ar-ar dates on muscovite from this deposit and k-ar age data on biotite from the pluton genetically related to the tin mineralization in this area demonstrates that the u-pb isotope system of cassiterite is a potential geochronometer. combined with the ar-ar dates of muscovite from this deposit, we can constrain the absolute age of tin-polymetallic mineralization in xianghualing at 154-157 ma. the dates obtained in this study, consistent with the published geochronological results from other important deposits in this region, reveal that the large-scale tungsten tin mineralization in the central nanling region was predominantly emplaced during 150-161 ma. |
