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.

Key words： Mesozoic volcanic rock zircon U-Pb dating laser ⁴⁰Ar/³⁹Ar dating
