英文摘要	An attempt was made to use CO2 laser step-heating method to date the late Pleistocene basaltic groundmass (DF-2) from Tengchong volcanic field. Among the fourteen heating steps, ten define a good inverse isochron (MSWD = 1.4) with an age of 32.2 +/- 7.1 ka (2 sigma). The inverse isochron also shows that the initial argon isotopic ratio is 297.1 +/- 2.0 (2 sigma) which is the same as the atmospheric argon at the 2 sigma error level. Study indicates that it is a useful means to date young volcanic groundmass with low K content by using CO2 laser step-heating Ar-40/Ar-39 method.
