Through detailed research on sample analysis result from energy spectrum,scanning electron microscope and ordinary optical microscope,an unusual amphibole mineral is discovered—magnesium rich arfvedsonite,sourcing from secondary alteration of titanite,which is a very unusual mineral metasomatic alteration phenomenon,that is,natrium and ma.

Using thin section X-ray diffraction techniques,his paper identified arfvedsonite in volcanic rocks from Songliao Basin,and thus confirmed that the volcanic rocks are composed of pantellerite.

The Upper Archean Enclavement of Magnesioriebeckites-Bearing Gneiss in Liaoning Province: Old Glaucophane-Schist Relict;

On the basis of the petrology,mineral chemistry and p-t conditions of the amphibole-bearing schists across Guandian,Zhangbaling,amphiboles in this schist belong to magnesioriebeckite,the average oxide contents: Al2O3=3.
