Fig. 16From: Intermobility of barium, strontium, and lead in chloride and sulfate leach solutionsNanoSIMS color composite images (a, b) and corresponding BSE images (c, d) of anglesite crystals. Red squares indicate 50 × 50 μm nanoSIMS mapped areas. Diffusion fronts of Ba (green) and Sr (red) can be clearly seen, apparently emulating crystallographic structures of the PbSO4 (blue)Back to article page
