Resumen:
The extremely acidic Lake Caviahue (pH= 2.2) (glacial volcanic origin) shows three groups of sediments (pH= 2.7) according to Fe, Al, Ca and S contents. The main P-fraction is linked to Al and Fe. This pattern is quite different to the P fractions that are found in sediments of neutral lakes mainly dominated by calcium. The high sulphur concentration could be important to sustain P in solution in the water column.
