micromorphological and mineralogical features of peat and swamp in golestan province; north of iran

in this study, we focused on detailed studies on micromorphological and mineralogical properties of three types of peat and swamp, to compare these different ecological area together. to achieve this goal, samples from a highland peat swamp (ghaleh-ghafeh ps), a peat swamp forest (suteh psf) and a costal swamp (galougah cs) in golestan province, north of iran have been considered. these studies were carried out polarized microscope using thin sections. quartz, muscovite, biotite, pyroxene, and fe-mn component are composed mainly soil materials. most common opaque minerals in samples of all studies area were consisted fe–mn component. root and other organ residues in some sections of suteh psf have been seen. oyster or limpet just have been seen in galougah cs sections. fe–mn component were most common that may be indicates mixing of soil material root and other organ residues in suteh psf shows this soil composed of a mixture of organ residues and organic material. presence of oyster or limpet in galougah cs sections may be related to location of this swamp.
