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).本数据集关联于发表于《地球化学与宇宙化学学报》（Geochimica et Cosomochimica Acta）的题为《高达20 GPa的玻璃态钙长石（CaAl₂Si₂O₈）的结构—纵声波速度关系：一项原位拉曼与布里渊光谱学研究》的文章，涵盖纵声波速度与布里渊散射相关数据。 本数据集包含两张附表：附表S1为布里渊频移（nVp）数值；附表S2为基于Kuryaeva等人2007年的原位高压折射率数据（DOI: 10.1134/S001670290703010X）计算得到的Vp（纵波速度）数值。
