| 摘 要： | 氮同位素地球化学在固体地球科学研究很少被关注,主要是由于在地壳岩石中氮丰度很低(＜1000ppm)和氮难于从硅酸盐中提取出来.归根结底是实验方法和分析技术制约其应用与发展.近年来,随着氮(NH4+)实验方法和分析技术的不断改进和提高,矿物和岩石中氮同位素地球化学研究有了较快的发展,在矿物岩石学及矿床地球科学研究中得到了一些应用.

| Abstract: | Nitrogen isotope geochemistry in minerals and rocks has not been fully studied,primarily because of very lower(<1000 ppm) concentration of nitrogen in the crustal rocks and the difficulty to extract nitrogen from silicate minerals and rocks.Actually the experimental and analytical method restricts its development and applications.During the past decade,the analytical method has been improved and geochemists have come to be interested in application of nitrogen isotopic geochemistry in rocks and minerals.Based on summarization of the recent results from international publications,this paper introduced the experimental and analytical method about nitrogen(NH4 ) from the whole rocks and single minerals. |
