Dissolution of single-crystal spheres of fluorite in the acid pH range always results in final dissolution forms that are mainly composed of (100) terraces. Any (100) face can only occur as the result of a face-specific adsorption effect. Such an eff

Dissolution rates of 39 rock-forming minerals were determined at 20 °C and 100 °C and different pH values, using experimental set-ups which achieve near-zero cation concentrations. Weathering rates in nature for rock above surface were estimated fr

Plutarch reported that the Spartan Monument from Delphi was coated with an unusual blue and glossy patina, due to peculiarities of the air inside the sanctuary. This bronze statuary group has actually vanished. The last remaining bronze sculpture fro

The ratio of growth rates of the K 2 (S,Cr)O 4 crystals in the [100] and [001] directions (the anisometry coefficient) is proportional to the initial effective supersaturation of the solutions from which the crystals were grown. The values of the fac
