| Summary: | Abstract.The soils studied represent Gelic Cambisols and Gelic Gleysols of Calypsostranda, Western Spitsbergen. They are characterized by varied basic properties and total composition. The studies allow us to conclude that the relationship Fe d /Fe t % facilitates to the determination of the soil weathering degree from the studied indicators, while the Parker's indicator, although giving similar results like the relationship Fe d /Fe t %, requires increased workload in the laboratory. The usage of the remaining indicators needs further studies on a larger scale and on more varied soil material. The chemical weathering processes of rocks lead to products whose chemical composition is changed in relation to the final material. Chesworth Iron contained in primary minerals is released under the influence of weathering processes and it is removed into the surrounding environment. Under its influence and together with the passage of time, secondary iron minerals are formed. They are crystal compounds, for example, goethite, lepidocrokite, hematite, poorly ordered -ferrihydrite, also amorphic. According to Mehra, Jackson, citrate buffer with strong reductive reactionary, dithionite |
