The objective of this study was to verify the effects rock dust on soil an area destined for pasture. Mineralogical analysis performed using X-ray diffraction, and major oxides minor elements were analyzed fluorescence. samples according PROFERT-MG. following identified from diffractogram total powder: quartz (43.66%), albite (38.10%), microcline (15.30%), muscovite (1.80%). Regarding elements,...

Aeolian dust (windblown silt and clay) is an important component in arid-land ecosystems because it may contribute to soil formation and furnish essential nutrients. Few geologic surfaces, however, have been characterized with respect to dust-accumulation history and resultant nutrient enrichment. We have developed a combination of methods to identify the presence of aeolian dust in arid region...

Mineralogical and chemical evaluations are necessary to investigate the background origins of materials. In terms residues commonly produced around world, ashes biomass stands out for its high calorific capacity use energy production at thermoelectrical facilities. Given current sustainability issues new demands from society, soil pine in Castelo Branco region were investigated research possibl...

Abstract A comparative analysis of areal and profile measurements magnetic susceptibility was carried out on the plots pf 100 m 2 in order to improve methods surface soil sounding for mapping purposes identification anomalies associated with anthropogenic pollution or disturbance layer. Two sites Haplic Chernozems one site Kastanozem (Endosalic, Cambic) were studied. Additionally, a catena Yerg...
