Dispersion halos found within the soil horizon have long been recognized surrounding ore deposits. Select elements found within this environment are weakly bound and can be extracted. The role of bacteria in low temperature biogeochemical processes, including the adsorption of metal ions and mineral precipitation, suggests that they should be involved in the creation of these halos. Three locations within the Abitibi greenstone belt were selected for bacterial characterization studies, Gémini, 180 East Zone, and the Cross Lake Property, with Cross Lake being the focus of a biodiversity study and a protease extraction experiment. Bacterial populations in dispersion halos are …
