SHRIMP U-Pb isotope age of volcanic rocks distributed in the Badaohao area, Liaoning Province and its significance

    Graphical Abstract
    • Abstract
  • A set of andesite volcanic rocks distributes in the Badaohao area in Heishan County,Liaoning Province.It’s geological age and stratigraphy sequence relationship between the Lower Cretaceous Badaohao Formation and the volcanic rocks can not make sure till now and is influencing the further prospect for coals.Zircon particles are sorted out from the samples and measured by using the SHRIMP method.The U-Pb isotopic age of these two sam-ples are 124.9±2.9Ma and 125.7±1.7Ma,belonging to Early Cretaceous Yixian Formation and is underlain the Badaohao Formation.
