Abstract

Abstract

Newly-determined zircon U-Pb ages, whole rock major and trace elements, Sr-Nd-Pb and zircon Hf isotope data, are used to firstly examine the geochemical characteristics of the ore-related syenite porphyry and trachyte in the Yao' an Au-Pb-Ag deposit, western Yunnan, and then to systematically discuss the origin and evolution processes of the parental magmas in this paper. The zircon U -Pb ages of the syenite porphyry and trachyte in the Yao' an Au -Pb -Ag deposit respectively are 33.8±0.42 Ma and 33.9±0.60 Ma. And their patterns of trace elements and REE, and the Sr-Nd-Pb isotopes, are very similar to the contemporary mafic volcanic rocks and lamprophyre from the western Yunnan, but obviously different from the contemporary alkali-rich adakitic rocks in the western Yangtze craton. The relationships of SiO₂ contents with major and trace element contents of the whole-rocks indicate that magmas for the syenite porphyry and trachyte could be formed by differentiation of the contemporary mafic magmas in the diggings. This implies that syenite porphyry and trachyte may have similar source to the mafic magmas. High Rb/Sr(≥ 0.1) and low Ba/Rb(< 20) ratios of the syenite porphyry and trachyte indicate that they were derived from a metasomatized enriched mantle source with abundant phlogopite. And the low εHf and the old model age of the rocks indicate that the metasomatism of the source region might happen in Mesoproterozoic. The alkali-rich magmation in Yao' an is closely related with the mineralization. The syenite porphyry and trachyte of Yao' an have a higher initial Pb isotopic composition than the mafic volcanic rocks and lamprophyre from the western Yunnan, which implies that some degrees of the crustal contamination might occur during evolution process of the magmas which could increase the metal contents of the magma and enhance the mineralization potential of the magmas. The moderate oxygen fugacity of the magmas in favour of the Au enrichment. And the obvious fractional crystallization of hornblende and the formation of abundant biotite indicate that the primary magmas were very hydrous, which facilitated the formation of oreforming fluids. All of these features could provide advantageous conditions for the mineralization in the Yao' an deposit.
