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
本文首先從常規~ （ 40 ） ar ~ （ 39 ） ar階段升溫定年實驗室的改進入手，進而建立了激光~ （ 40 ） ar ~ （ 39 ） ar定年實驗室，利用這兩種先進同位素地質定年方法，結合其他手段，對青藏高原腹地和北緣的阿爾金斷裂系多期地質事件進行了詳細的同位素年代學研究：一、參照國際先進實驗室的流程，對我們的常規~ （ 40 ） ar ~ （ 39 ） ar階段升溫實驗室在樣品的預處理、樣品的照射條件和系統空白測量及校正等方面進行了改進，使之產出的同位素年代數據更可靠並為國際同行所承認。 -
