| 摘 要： | 通过对国内外大陆板内构造环境玄武岩的研究,提出了大陆板内不同构造环境玄武岩的微量元素判别方法及判别标志,即大陆板内玄武岩的Th/Nb>0.11,Nb/Zr>0.04,其中,大陆裂谷区玄武岩的Th/Nb=0.11~0.27,大陆拉张带玄武岩的Th/Nb>0.27(一般0.27~0.67),陆-陆碰撞带玄武岩的Th/Nb>0.67。

| Abstract: | Based on study of the tectonic settings for continental intraplate, distinct ways and signs for identification of the different tectonic settings in continental intraplate by means of trace elements were put forward in this paper. The basalt shows Th/Nb>0.11 and Nb/Zr>0.04 in continental intraplate, Th/Nb=0.11～0.27 in continental rift, Th/Nb>0.27 (generally 0.27～0.67) in tensional zone, and Th/Nb>0.67 in collision zone between two continental plates. |
