Cím:Mineralogical composition of genetic horizons of crusty meadow solonetz soil profile from Püspökladány based on X-ray diffraction and thermal analysis / Gyula Szöőr, Éva Balázs, Tibor Novák, Péter Kovács-Pálffy, Péter Kónya
Dátum:2008
Megjegyzések:A typical solonetz soil profile, characteristic for the Hortobágy region (Eastern Hungary) was chosen in Ágota-puszta, Püspökladány, to study the mineral distribution in genetic soil horizons. The analyses were carried out for getting data about mineral composition of the regions most typical soil type, and compare it with solonetz profiles from other regions of the Hungarian Great Plain. On the other hands it was aimed to point on the possible mineral transformation processes causing the strong differentiation between genetic horizons of the profile. The analysis established that the mineral composition of the parent rock is very similar to that of other Hungarian solonetz soils. The dominant mineral is quartz (44%). Second frequent mineral group are clay minerals (35%), their proportion is higher, than the proportion of the clay size fraction determined by the sedimentation method, (19.5%), therefore one part of them falls in the size class >2 ?m. Main components are also micas (muscovite+illite)(14%) and plagioclase (9%). As a consequence of soil formation, the upper horizons show significant deviations from the mineral composition of the parent rock. Proportion of quartz reaches 59% in ?A" horizon. A higher amount of clay minerals (45%) is characteristic for the ?B" horizon as a result of clay production and illuviation. As final residual products of mineral degradation goethite, hematite, gypsum and amorphous components occur in lesser amounts, without significant differences in their vertical distribution.
