Sr-Nd-Pb Isotopic Geochemistry of the Hukeng Granite Body in Jiangxi Province, South China

Abstract:

The Mesozoic Hukeng granite body locates in southeast limb of Wugongshan compound anticline in Jiangxi Province, South China. This study uses samples from the Hukeng granite body to determine the characteristics of Sr-Nd-Pb isotopes and source of the granite body. The rocks have ⁸⁷Sr/⁸⁶Sr ratios as high as 0.84112, suggesting that crustal contamination existed there. The rocks have higher ratios of ⁸⁷Rb/⁸⁶Sr, ⁸⁷Sr/⁸⁶Sr and (⁸⁷Sr/⁸⁶Sr)_i, and lower ratios of ¹⁴⁷Sm/¹⁴⁴Nd, ⁴³Nd/¹⁴⁴Nd and lower ε_Nd(t), indicating that the Hukeng granite body possessesEMⅡ-like characteristics. Combined with Pb isotopic values (²⁰⁶Pb/²⁰⁴Pb ratios from 18.5313 to 18.8460, ²⁰⁷Pb/²⁰⁴Pb ratios from 15.6562 to 15.6782 and ²⁰⁸Pb/²⁰⁴Pb ratios from 38.7015 to 38.7565), the Hukeng granite body originated from EMⅡ and suffered crustal contamination in certain extent.
