Data for: Structure—longitudinal sound velocity relationships in glassy anorthite (CaAl2Si2O8) up to 20 GPa: An in situ Raman and Brillouin spectroscopy study

This data is the longitudinal sound wave velocity and Brillouin scattering data associated with the article titled, "Structure—longitudinal sound velocity relationships in glassy anorthite (CaAl2Si2O8) up to 20 GPa: An in situ Raman and Brillouin spectroscopy study" in Geochimica et Cosomochimica Acta. It includes two table: Table S1:The Brillouin shift (nVp) values and Table S2: The calculated Vp values based on the in situ high pressure refractive index data of Kuryaeva et al., 2007 (DOI: 10.1134/S001670290703010X).本数据集为发表于《地球化学与宇宙化学学报（Geochimica et Cosmochimica Acta）》的论文《高达20 GPa的玻璃状钙长石（CaAl₂Si₂O₈）的结构-纵波速度关系：原位拉曼与布里渊光谱学研究》配套的纵波速度与布里渊散射数据。本数据集包含两张附表：附表S1：布里渊频移（nVp）数值；附表S2：基于Kuryaeva等人2007年发表的原位高压折射率数据计算得到的纵波速度（Vp）数值（DOI: 10.1134/S001670290703010X）。
