Geoenvironmental studies and heavy metal mapping in soil: the case of Ghohroud area, Iran

摘要: Geological features play a key role in determining variations elemental concentrations an area. Among different geological phenomena, intrusion of igneous bodies and associated alteration contribute significantly to the introduction heavy metals into This study has focused on Ghohroud, central Iran, which is situated Urmieh–Dokhtar magmatic arc (UMDA) belt, magmatism developed as result granodiorite body. The area later been affected by hydrothermal fluids, resulting argillic propylitic contact metamorphism. objectives this were assess degree contamination describe surface soil geochemical relation geology, lithology, activity Ghohroud Soil sampling was used for study, 96 samples collected analyzed ICP-OES. elements, obtained Pb, Zn, Ni, Cu, As, Co, V, Mo selected statistical treatment. Different geoenvironmental indices calculated, results showed that Mo, Zn present at contaminating concentration. Remote sensing studies employed mapping. It concluded development types proximity intrusive main contributors increased metal
