Pressure, temperature, P- and S-wave velocities and density of MgSiO3 majorite

Pressure, Temperature, P- and S-wave velocities and density of MgSiO3 majorite obtained simultaneously from travel time, X-ray radiography length, and X-ray diffraction measurements on polycristalline aggregates up to 18.4 Gpa and 2000 K, in the multianvil apparatus at the beamline BL04B1 in SPring-8.本数据集同步测得MgSiO₃镁榴石（MgSiO₃ majorite）在最高18.4吉帕斯卡（GPa）、2000开尔文（K）条件下的压力、温度、纵波（P波）与横波（S波）速度及密度；相关数据通过对多晶聚集体开展声波走时、X射线辐射成像长度及X射线衍射测量获取，实验在SPring-8同步辐射光源BL04B1光束线的多砧高压装置（multianvil apparatus）中完成。
