| 英文摘要 | The Dadian alkaline intrusive complex is located within the Sulu orogenic belt, and includes hornblende syenite, syenite, quartz syenite and syenite porphyry. All the rocks from the complex show high SiO2, K2O + Na2O and LREE and low CaO, FeOT. MgO and HFSE (Nb, Ta. P, Ti) concentrations. The Sr, Nd, and Hf isotopic compositions ((Sr-87/Sr-86)(i) = 0.708505-0.70876, epsilon(Nd)(t)= -16.5 to -17.9, epsilon(Hf)(t) = -21.5 to -16.4) of the rocks fall within the compositional field of mafic dykes occurring nearby, suggesting that the Dadian alkaline complex was mainly derived from an enriched lithospheric mantle. The initial Pb compositions (((206)pb/Pb-204)(i) = 16.706-16.779, ((207)pb/(204)pb)(i) = 15.427-15.450, (Pb-208/Pb-204)(i) = 37.266-37.352) of the Dadian rocks are lower than those of the Yangtze lithospheric mantle, albeit similar to that reported from beneath the North China Craton, implying that the mantle source of the Dadian alkaline complex most likely belong to the North China Craton. The relatively high SiO2 and HREE contents and low Nb/Ta ratios as well as strongly negative Eu and Sr anomalies of some of the rocks from the Dadian complex suggest that crustal material was also involved in the formation of this complex and that the crustal component was probably derived through partial melting at low pressure. The high crystallization temperatures revealed by zircon saturation thermometry and low pressures suggested by Al-in-hornblende barometry indicate that the Dadian alkaline complex crystallized at high temperature and intruded into shallow crustal level. This intrusive complex does not show any relationship with post-orogenic process in the region, and its petrogenesis is inferred to be associated with the Paleo-Pacific subduction tectonics.
