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...
