对峨眉山二滩高钛玄武岩高场强元素的研究表明, Zr/Hf比值出现了明显分异, 可分为高Zr/Hf组和低 Zr/Hf组两组玄武岩. Zr/Hf比值的分异与岩浆结晶分异作用无关, 而是由部分熔融和地幔源区的不同所导致, 暗示高Zr/Hf组和低Zr/Hf组玄武岩分别具有不同的部分熔融条件和不同的地幔物质组分 |

Variations of high-field strength element(HFSE)of the Ertan high-Ti basalts in the Emeishan suggest that Zr/Hf ratios were fractionated. According to the fractionation, the Ertan high-Ti basalts can be devided into high Zr/Hf group and low Zr/Hf group based on Zr/Hf ratios. The fractionation of Zr/Hf is not related with crystallization of basaltic magmas but partial melting and distinct compositions of mantle. This implies that high Zr/Hf basalt and low Zr/Hf basalt possessed distinct compositions of mantle and underwent different surroundings of partial melting, respectively |
