主 题:magmatism geochronology zircon apatite gold deposits Jiaodong Peninsula
摘 要:The Mesozoic intrusions of the Jiaodong Peninsula,eastern China,host giant gold *** the genesis of these deposits requires the determination of the source of the parental auriferous fluid and the timing of gold mineralization,which are strongly influenced by the cooling/uplift histories of the hosting *** performed an integrated U-Pb geochronology study on both zircon and apatite from four major magmatic episodes of the Jiaodong *** zircon and apatite U-Pb ages are 156.9±1.2 and 137.2±2.4 Ma for the Linglong intrusion,129.9±1.0 and 125.0±3.8 Ma for the Qujia intrusion,119.5±0.7 and 117.2±1.8 Ma for the Liulinzhuang intrusion,118.6±1.0 and 111.6±1.6 Ma for the Nansu intrusion,*** coupled zircon and apatite data of these granitoids indicate a slow cooling rate(11.9°C/Ma)in the Late Jurassic,and rapid uplift and cooling(35.8-29.2°C/Ma)in the Early *** dramatically increased uplift and cooling period in the Early Cretaceous are contemporaneous with large-scale gold mineralization in the Jiaodong *** implies that thermal upwelling of asthenosphere and related tectonic extension played an important role in gold remobilization and precipitation.
