摘　　要：本文用Raman光谱技术测量了经过高温高压处理的叶蜡石和白云石的相变。实验显示叶蜡石与白云石的一级散射光谱的数量随着温度、压力增加有明显的增加,这表明叶蜡石与白云石在高温高压条件下发生了相变。Raman光谱的数据比较X射线的数据更加直观和清晰。Pyrophillite and dolomite treated by HT-HP have been measured by Raman spectroscope R1000. First order Raman scattering of pyrophillite and dolomite has been studied. It was discovered that the number of first order scattering of pyrophillite and dolomite chanced gradually with increasing pressure and temperature, and new phase was appeared.
