Loss in ground elevation in the Zennare Basin, South of the Venice Lagoon, has been correlated to peat oxidation with consequent formation and emission of carbon dioxide and mass loss. A detailed textural, geotechnical, mineralogical and geochemical investigation has been carried out in order to better understand the mass loss process in the uppermost peat layer. Because of the high organic and moisture content in the soil, an Environmental Scanning Electron Microscope (ESEM) equipped with Energy Dispersive Spectrometer (EDS) was used to analyze undisturbed and untreated peat samples. A geotechnical classification of the organic soil is proposed using different in situ laboratory methods based on basic geotechnical properties such as structures, water content, ignition loss, and humification grade.

Because of the high organic and moisture content in the soil, an Environmental Scanning Electron Microscope (ESEM) equipped with Energy Dispersive Spectrometer (EDS) was used to analyze undisturbed and untreated peat samples.
