The hydrostatic compressions (ΔV/V0) of granodiorite, basalt, dolomite, and tuff (all from the Nevada test site), Indiana limestone, two rock salts, and anhydrite were measured to 46 kb at 25°C. A phase transition was observed in anhydrite (CaSO4) at 19.6±0.5 kb with a volume change of 4.1 per cent. The compression data for granodiorite, basalt, dolomite, tuff, and limestone were in good agreement with dynamic results for similar rocks.
