Abstract
We explored the potential use of combining wavelength-dispersive X-ray spectroscopy (WDX) and micromorphology of thin sections to identify minerals in peat soils. Peat soil minerals from three peats and swamps across Golestan Province in northern Iran were first characterized by micromorphological studies. Soils were composed mainly of quartz, muscovite, biotite, pyroxene, sericitized Fe-nodules, and iron-rich garnet. In addition, micromorphological results indicated that Galougah Coastal Swamp sections contained some inorganic residue with biological origin including oyster and limpet, which may be related to the swamp’s location near Gorgan Gulf. In order to determine mineralogical properties of samples, twelve unknown grains were chosen for elemental concentration map studies. Quartz, garnet, ilmenite, calcite, and pyroxene in Suteh samples; epidote and Fe-nodule in Ghaleh-Ghafeh Peat Swamp; and barite, phyllosilicates, and calcite in Galougah were identified by WDX mapping of Si, Al, Fe, Ca, Mg, C, Ba, S, and Ti. Composition of the oysters’ body was also analyzed by WDX for Si, Ca, Fe, and C. The results indicated that most of the minerals in all sections likely formed through weathering, inheriting their composition from the parent rock. This research suggests that merging micromorphology and SEM/WDX image techniques can be useful in confirming the presence of mineral particles in soil science.
