Figure 8
Volume variation of malachite as a function of pressure. The powder (filled circles) and single-crystal (empty circles) data are reported for malachite, together with the volume data for the high-pressure RS structure. The EOS for the MS and RS phases are also reported. The extrapolation of volume at ambient pressure for the HP phase indicates an increase of 3.1% in density (ρ0 = 4.051 g cm−3 for MS and ρ0 = 4.177 g cm−3 for the RS structure). |
