英文摘要 | Soil genesis and clay mineralogy studies play an important role in sustainable soil and agriculture management. Soil properties are highly affected by geomorphic position. To study the physicochemical soil properties and clay mineralogy related to geomorphic surfaces, 12 representative pedons on different landforms in the Mahan-Joupar area, central Iran, were selected. Soil moisture and temperature regimes of the area were aridic and mesic, respectively. Rock and mantled pediments, alluvial fan, inselberg, plain, and transitional surfaces were among the different landforms studied. Alluvial fan was also divided into stable and unstable surfaces according to detailed field studies. Argillic horizon found in stable alluvial fan surfaces was attributed to the presence of a more humid paleoclimate in the history of the area. Coating of calcite on clay films observed by SEM showed that clay was illuviated in more humid periods of the past and then followed by calcium carbonate illuviation during arid climates. Smectite, kaolinite, chlorite, illite, and palygorskite clay minerals were identified by X-ray and SEM observations. Finally, a close relationship between the geomorphology and soil genesis and clay mineralogy was found in the area. |
