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, ...

electron-probe microanalyses and scanning electron microscopy of chrornitites from some ultramafic members of neyriz ophiolite indicate that sulifides of platinum- group minerals (pgms) occur as solid inclusions in chromite grains. laurite with the general formula of (ru ,os ,lr ) s , and erlichmanite are the main identified sulfide phases. the pgms occur as 4 to 20 microns euhedral to rectangu...

the study area is located in the south of kerman province and in the esphandoghe- dolatabad zone. numerous chromite ores were found in the area that has been explored by surface outcrops. with respect to the previous exploration- exploitation works and the absence of the pilot layer, the best option was the boreholes’ drilling was the best choice in order to complete the detailed information. f...

the spatial distribution of mineralization is the foremost concern in regional exploration and it could be considered as a very important tool in the investigation of mineral deposits. there are several data manipulation methods by which the data can be evaluated. fry analysis is a good method to determine the direction(s) of maximum continuity of the deposits and could be used in different typ...
