【摘要】 首次对山东招远灵雀山金矿床富金石英脉Rb-Sr等时线年龄测定,获得(116±12)Ma成矿年龄。这与胶东地区主成矿期为(120±10)Ma相吻合,从而说明招-平断裂带上盘金矿大规模成矿期发生于早白垩的构造体系转折期,由此可以看出招-平断裂带上盘具有良好的成矿条件。更多还原

【Abstract】 In order to understand the genesis of gold deposits,it is fundamental to know the age of gold deposition.The Rb-Sr isochron dating methods were adopted to date the ore deposits.The results from the study indicate that the age of the Lingqueshan gold deposit is(116±12) Ma.It is consistency with the age of Jaodong gold deposits of(120±10) Ma.It means that the large-scale metallogeny of the Zhao-Ping fault zone hanging wall took place in early cretaceous occurred in north western Jiaodong Peninsula and with favorable metallogenic conditions.更多还原
