英文摘要The Yinshan deposit is a large epithermal-porphyry polymetallic deposit, and the timing and petrogenesis of ore-hosting porphyries have been hotly debated. We present new results from geochemical, whole-rock Sr-Nd and zircon U-Pb-Hf-O isotopic investigations. Zircon U-Pb data demonstrate that the quartz porphyry, dacitic porphyry, and quartz dioritic porphyry formed at 172.2 +/- 0.4Ma, 171.7 +/- 0.5Ma, and 170.9 +/- 0.3Ma, respectively. Inherited zircon cores show significant age spreads from 730 to 1390Ma. Geochemically, they are high-K calc-alkaline or shoshonitic rocks with arc-like trace element patterns. They have similar whole-rock Nd and zircon Hf isotopic compositions, yet an increasing trend in E-Nd(t) and E-Hf(t) values typifies the suite. Older (inherited) zircons of the three porphyries display Hf compositions comparable to those of the Jiangnan Orogen basement rocks. In situ zircon oxygen isotopic analyses reveal that they have similar oxygen isotopic compositions, which are close to those of mantle zircons. Moreover, a decreasing trend of O-18 values is present. We propose that the ore-related porphyries of the Yinshan deposit were emplaced contemporaneously and derived from partial melting of Neoproterozoic arc-derived mafic (or ultra-mafic) rocks. Modelling suggests that the quartz porphyries, dacitic porphyries, and quartz dioritic porphyries experienced 25%, 10%, and 10% crustal contaminations by Shuangqiaoshan rocks. Our study provides important constraints on mantle-crust interaction in the genesis of polymetallic mineralization associated with Mesozoic magmatism in southeastern China.
