Abstract [en]

Ferrous and ferric sulphates and (oxy)hydroxides can grow on pyrite surfaces and slow oxidationrates. However, in northern climates, repeated freeze/thaw cycles can cause cracks, channeling and exposureof new surfaces. In the present study, weathering in a repeated freeze/thaw experiment was compared to aregular humidity cell experiment. Introductory results (after 17 weeks) show very small changes in pH for thefreeze/thaw system (pH around 5), while pH in reference and humidity cell systems decreased rapidly thefirst weeks (to around 4). An increase in electrical conductivity, sulphate and major ions was noticed in thetwo latter systems.
