| 摘 要： | Based on their REE features, stratoid or lenticular amphibolites in the Dabie Complex are di-vided into two types:one is characterized by flat REE distribution patterns and the other by LREE-enrichment. Results of the REE quantitative modeling suggest that the amphibolites were formed from 20% partial melting of garnet lherzolite and 35-56% fractional crystallization of olivine(type TH1) or 14-20% fractional crystallization of olivine and clinopyroxene(type TH2).

| Abstract: | Based on their REE features, stratoid or lenticular amphibolites in the Dabie Complex are divided into two types: one is characterized
by flat REE distribution patterns and the other by LREE-enrichment. Results of the REE quantitative modelling suggest that
the amphibolites were formed from 20% partial melting of garnet lherzolite and 35–56% fractional crystallization of olivine
(type TH1) or 14–20% fractional crystallization of olivine and clinopyroxene (type TH2).
