heavy metal concentration in the soils and sediments has increased worldwide during the last century due to the mining, smelting, and industrial activities. the forumad chromite deposit is located in the sabzevar ophiolitic complex (soc), with a long history of mining activities, yet very little is known about the heavy metal contamination in its surrounding environment. in this research work, ...

biogeochemical investigation on s. orientalis, a flora growing on the soils derived from serpentinized dunite in the forumad area, sabzevar ophiolite has been conducted in order to examine the plant-soil relationship in chromite prospecting. due to engagement of cr in the chromite crystal structure and its non-essential role in the plant’s life cycle, ni was used as pathfinder element in biogeo...

Numerous post-ophiolite intrusions exposed into the late Cretaceous–Paleocene Sabzevar ophiolite belt, northeast Iran. The intrusions consist of calc-alkaline intermediate to felsic rocks with metaluminous to peraluminous in nature and adakitic affinities. Based on U-Th-Pb dating on separated zircons by SHRIMP Ⅱ, the emplacement age of these rocks into the ophiolite zone is constrained to ~45 M...

the forumad ophiolite in the northwestern part of the sabzevar region has embraced the largedepleted harzburgites and dunitic bodies associated with podiform chromitites. in some deposits, chromitegrains have segregated as nodules. the stretched shape along with high cr2o3 and tio2 contents are thecharacteristics of the nodules. compared to the other tethyan nodular chromites, the forumad nodul...
