Comparison between Mineralogical Properties of Oak Forest and Un-Cultivated Soils in Iraqi Kurdistan Region
Abstract
This study was conducted to identify the mineralogical properties of oak forest and uncultivated soils at 12 locations in the Iraqi Kurdistan region, which included (Brifca, Gara, and Matin) in Duhok governorate, (Awagrd, Bilah, and Malakan) in Erbil governorate, (Badawan, Bardanga, and Chwarta) in Sulaimani Governorate and (Bakhakon, Hawar, and Sartak) in Halabja governorate. Clay minerals were identified from X-ray diffraction data and peaks. Peak height is used as a rough indicator of the relative abundance of minerals. In general, the expansion of 14°A to 17°A in the ethylene glycol treatment was not detected because measuring started at 5? so that’s why we cannot differentiate between Chlorite and Smectite in that treatment. Swelling chlorite was the dominant mineral in these soils. While the miner clay minerals at those locations were Kaolinite. Mica was identified at all locations, while the dominant type of mica in forest soils was Muscovite, which was obtained from 6 sites, and Mica Biotite was obtained from 4 sites. In uncultivated sites, both types of mica were recorded at 5 sites.
