| 摘 要： | 利用热液金刚石压腔研究了白云石在温度298 K、压力100~1 000 MPa下C-O键弯曲振动峰1ν097的拉曼变化特征。结果表明,在实验的压力范围内白云石稳定,其拉曼位移和压力具有很好的线性关系,拟合后得出压力与白云石1 097 cm-1拉曼线频率位移的关系为:p=143.47(Δpν)1 097+102.67(1 097

| Abstract: | The variation characters of Raman spectra of C-O band-liberation peak ν1 097 of dolomite at the experiment pressure of 100～1 000 MPa and temperature of 298 K were studied using hydrothermal diamond anvil cell(HDAC).The results show that dolomite is stable under the experimental pressure with good correlation between the Raman peak position shift and the pressure.The relationship between the system pressure and Raman peak position shift of calcite(1 097 cm-1) is given as follow: p=143.47(Δνp)1 097+102.67(1 097<νp<1 103).Therefore,dolomite can be used as a pressure gauge for the hydrothermal diamond anvil cell. |
