  1. Fundamental of laser 40ar / 39ar dating method : our laboratory has successfully set up the laser microprobe 40ar / 39ar geological dating method. our works include adjustment of the high - gain electron multiplier in mass spectrometer and correction of mass discrimination, adjustment of the laser, test for absorption ability of minerals to laser, designing and manufacturing high - vacuum sample chamber, sample preparation and irradiation, research on the variability of j values on the surface of rock chips, measuring atmospheric argon, determination and correction of blanks and ages, etc. the laser microprobe technique is particularly effective for some geological samples. it can be used, for example, for research of distribution of the components in extremely small samples that are very difficult to be separated and purified and those which contain excess argon
