Groundwaters low in pH due to dissolved carbon dioxide and to acids liberated by surface waters from the upper horizons of the podsol profile have caused rapid weathering of limestone erratics occurring sporadically in glaciogenic material in the Lohja region. Especially the calcitic portion of the limestone has been dissolved and partly replaced by a brownish black earthy substance consisting of hydrous oxides of iron and manganese. Dolomitic limestone has likewise been dissolved; the calcium has gone into solution, but the magnesium has been reprecipitated.
