    COMPARISON BETWEEN THE ZIRCON U-Pb DATING AND LASER 40Ar/39Ar DATING FOR THE MESOZOIC VOLCANIC ROCKS

      摘要
    • 摘要: 通过对龙江组和光华组锆石Pb/U和激光40Ar/39Ar两种方法同位素定年结果的对比研究，发现二者对于中生代火山岩的定年结果极为相近.后者相对快捷、方便、经济.认为激光40Ar/39Ar定年，适用于1：5万和1：25万区域地质调查及相关的综合研究项目工作.

       

      Abstract: The results of zircon U-Pb dating and laser 40Ar/39Ar dating for the volcanic rocks from the Longjiang and Guanghua formations are compared respectively. The two dating methods display a significant close age. Due to its economy and convenience, the laser 40Ar/39Ar dating method would be useful and practicable in the 1:50 000 and 1:250 000 regional field works and other studies.
