摘要
埃达克岩是目前地学界的研究热点 ,普遍认为具有两种成因类型。在大量分析已经发表的两类埃达克岩资料的基础上 ,发现通过 Sr/Y- w (Y)散点图、Sr- Y× 10 - Zr三角图、Y/Yb- Sr/Y- L a/Yb三角图能够判别 , 类埃达克岩。
One of the hottest topics in current geosciences was adakite research which was commonly thought to have two kinds of genetic types.Based on the analysis of published adakite data,this paper probes into the discrimination of the two kinds of adakite.The result shows that the two kinds of adakite can be correctly discriminated by Sr/Y-w(Y) scatter diagram,Sr-Y×10-Zr triangle diagram and Y/Yb-Sr/Y-La/Y triangle diagram.
