Calcium oxalate biominerals in soils of Laguna de los Padres, Buenos Aires, Argentina

The general mineralochemical characteristics of calcium oxalate: Whewellite (CaC 2O 4.H 2O) and weddellite (CaC 2O 4.(2+X) H 2O) from litter layer and minerals horizons of the Pampean Plains soil are described by first time in Argentine. The studies are carried out using polarisation microscopy and...

520 3 |a The general mineralochemical characteristics of calcium oxalate: Whewellite (CaC 2O 4.H 2O) and weddellite (CaC 2O 4.(2+X) H 2O) from litter layer and minerals horizons of the Pampean Plains soil are described by first time in Argentine. The studies are carried out using polarisation microscopy and scanning electron microscopy plus energy dispersive microanalysis. The results indicate a predominance of weddellite crystals such as twinned tetragonal dipyramid and bipyramid crystals arranged as rossetes and druses with sizes varing between 5 and 10μm in the litter layer of the acacia forest. The whewellite, pseudo-rhombohedra, isodiametric crystals, appear as individual 5μm diameter crystals and rossetes 5 to 10μm diameters crystals, can be found in the A horizons of forest and grass praire. A direct relation has been found between: Humidity degree, development of the litter layer and fungi colonisation, with respect the amount and development of biominerals.  |l eng
