| Abstract: | Located in the northern margin of North China craton,the Liubagou gold deposit of Inner Mongolia is a large ore deposit characterized by widespread K-feldsparthization.The authors apply the 40Ar-39Ar isotopic dating of K-feldspar to define the mineralization age,and give a detailed study on the Pb isotopes of ore.In the density map of 40Ar-39Ar age,the peak region of 260-360 Ma is accordant with the main emplacement ages of the intrusions(220-350 Ma).Combining with the published isotopic geochronology data ... |
