Barro Alto ultramafic soils
Goiás, Brazil (Central-West ultramafic complexes), Brazil
Soils
- Type
- Soil
Soils of the Barro Alto ultramafic complex, rich in nickel (3.3 to 14.2 g/kg) and iron, sampled in 2013 and 2014 near the plant. Lighter than the ores and slags: natural nickel can be told apart from smelter nickel. Indicative coordinates.

| −0.13 ± 0.11 ‰ | −0.3 / 0.11 ‰ | 15 | topsoil Mean and standard deviation recalculated from 15 values. BA_S1 to BA_S13 (including three depths of BA_S4); BA_S7 and BA_S8, low in Ni, are the only positive ones. | Ratié et al.
