Abstract: | Rumex acetosella and Minuartia verna are confined to mineralized ground in Macedonia. These plants contain relatively high concentrations of heavy metals such as copper, zinc, lead and manganese, and are to that extent, valuable indicators of sulphide mineralization, either pyrite + chalcopyrite or pyrite + chalcopyrite + sphalerite + galena. There is a direct relationship between the metal content of the plant ash and the metal content of the soils and mineralized substrate. |
