Analysis on the Characters of Origin and the Effective Factors of Quality Grading of Qingtian Stones

Zhu Xuan-min

Abstract

The sample of qingtian stones were analyzed and tested by X-ray diffraction and scanning electron microscope.The results showed that the main minerals of qingtian stones was pyrophyllite and their characteristics of origin had some connection with their mineral composition.The quality of qingtian stones was exposed to the mineral elements and the internal structure.
