Additional file 1: of Melting relations in the Fe–S–Si system at high pressure and temperature: implications for the planetary core

a 2D images of diffraction patterns of the Fe–S–Si system at 42.3–44.1 GPa (Run FESSI20) corresponding to the X-ray profile given in Figure 1(a). A at 44(1) GPa and 1450(50) K, B at 44(4) GPa and 1650(50) K, C at 44(4) GPa and 1730(50) K, and D at 42.2(0.3) GPa and 300 K after quenching from 1730 K. NaCl was used as the pressure medium and thermal insulator. b 2D images of diffraction patterns of the Fe−S−Si system at 49.2-58.2 GPa (Run FESSI10) corresponding to the X-ray profile given in Figure 1(b). A at 58(5) GPa and 1650(50) K, B at 54(4) GPa and 1810(50) K, C at 54(4) GPa and 1840(50) K, and D at 49.2(0.6) GPa and 300 K after quenching from 1840 K. (DOCX 1725 kb
