Maritime Antarctica soils studied by Mössbauer spectroscopy and other methods
Soil samples from the King George Island, Antarctica, have been studied by 57Fe Mossbauer spectroscopy, X-ray diffractometry, radiometry, neutron activation analysis and chemical analytical methods. X-ray diffractometry measurements have identified soils containing different volume ratios of quartz,...
