| Abstract: | The Rb-Sr isochron ages of 719 Ma and 726. 6 Ma, obtained from staurolite schist and plasioclase-hornblende schist in Xiangshan district in central Jiangxi province respectively,indicate that the metamorphic rocks in Xiangshan region are redefined as Neoproterozoic, but not Caledonian. On the basis of cluster analysis and correspondence analysis of trace element geochemical ratio,it is not confirmed that the original rocks of Xiangshan metamorphic basement belong to Sinic,but closely correspond with Chencai group in Cathaysian block. |
