Abstract

Abstract

The Yujiashan Cu-Ni deposit of Hannan complex is located in the southwest of the Wangjiangshan basic massif, in the west of the northern margin of the Yangtze craton. There is less study on the diagenesis age, mineralization age and the nature of magma source of the outcropped rock mass, which affects the understanding of the deposit genesis. The data of LA-ICP-MS zircon U-Pb dating and in-situ Lu-Hf isotope of the typical outcropped ore-bearing and surrounding rocks were analyzed in the study. The results show that the mineralization age is about or a little late than (791±4) Ma, and the diagenesis age is about (808±6.8) Ma. Furthermore, the in-stiu zircon Hf isotopic analysis indicates that the ε_Hf(t) values of ore-bearing rock range from +9.5~+10.9, with an average value of +10.7 and Hf model ages ranging from 924 Ma to 974 Ma; the ε_Hf(t) values of surrounding rock range from +8.7~+11.1, with an average value of +9.9 and Hf model ages ranging from 924 Ma~974 Ma. Coupled with the available published data, it is proposed that the basic massif of the Yujiashan Cu-Ni deposit maybe derived from the partial melting of depleted mantle materials of late Middle Proterozoic-Neoproterozoic age in the active continental margins setting.
