  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

    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。

  3. By having conducted 40ar - 39ar dating of 35 samples and sm - nd dating of 19 samples from the linzizhong volcanic rocks, the post - collision volcanic rocks and a granite dike and the yarlung zangpo ophilite, the dissertation provides significant new data and results for optimizing the time framework of tectonic - magmatic event s of this region. according to isotopic dating of 9 samples, 12 experiments survey in the main trunk profile, the eruption age of the linzizhong volcanic rock in the linzhou basin has been determined as 54 - 64ma

    本論文通過35個樣品的~ （ 40 ） ar - ~ （ 39 ） ar及19個樣品的sm - nd同位素測年，獲得了關于俯沖?碰撞階段形成的林子宗火山巖、后碰撞火山巖與花崗巖及雅魯藏布蛇綠巖的同位素年齡數據，為完善研究區構造?巖漿事件的時間格架提供了新的資料與成果。
