Study on the Relationship between the Relative Content of Moganite and the Crystallinity of Quartzite Jade by Raman Scattering Spectroscopy, Infrared Absorption Spectroscopy and X-ray Diffraction Techniques

Autor: ZHOU Dan-yi, CHEN Hua, LU Tai-jin, KE Jie, HE Ming-yue

Publikováno v: Yankuang ceshi, Vol 34, Iss 6, Pp 652-658 (2015)

Quartzite jade is composed of α-quartz and another silica phase, moganite, which forms under low pressure and low temperature conditions. At present, there are few studies on the relationship between the relative content of moganite and the crystall
