1 Inland acid sulfate soils a new geochemical sampling medium: a regional orientation study from the Mount Lofty Ranges, South Australia M. Skwarnecki 1 & R. Fitzpatrick 2 1 Geological Survey of Western Australia 2 CRC LEME/CSIRO Land & Water, Adelaide

3 Outline of talk What are inland acid sulfate soils? Where do they occur? How do they form? Regional case study Kanmantoo, South Australia Local example Wheal Ellen Implications for mineral exploration
4 What are Acid Sulfate Soil materials? Soils and sediments that contain iron sulfides, which when drained or disturbed, form sulfuric acid Main form of iron sulfide Pyrite (FeS 2 ) Also iron mono-sulfides (FeS) each mole of pyrite 2 moles sulfuric acid or 4 moles acid
5 Pyrite (FeS 2 ) in sulfidic material Pyrite (py( py) ) crystals in framboids Sphalerite (ZnS)(sp) and Pb sulfide crystals (bright streaks) in plant rootlets
6 Iron monosulfides (FeS) Monosulfidic Black Ooze (MBO) Reacts rapidly when disturbed De-oxygenates water supplies Poorly crystalline crystals Iron oxyhydroxysulfates, from oxidation of FeS scavenge elements (As, Cd etc)
7 Where do inland Acid Sulfate Soils occur? Mt Lofty Ranges, SA
8 Geologically controlled groundwater discharge zones Transporting SO 4 2- & Fe 2+ to surface (formation of sulfides)
