Geochemistry and reserve estimation of Tajar feldspar mine (Samen, Hamedan province) ; based on detailed exploration data during mining

The Tajar feldspar deposit is located at 15 km southwest of Malayer city, 4 km northwest of Samen city, in the Hamedan province and west of Iran. Study area is located in the north part of the Sanandaj-Sirjan geological zone. Detailed exploration activities carried out for determining of geometrical data of mineralized zones. Indeed, according to the morphological and geometrical data of deposit, the rectangular exploration grid was designed and 45 exploratory boreholes (520 meters total depth) were drilled. Furthermore, for determining of shape and dimension of mineral deposit, lithological columns of mineral deposit and host rocks were designed. Then by providing their geological profiles, at first the volumes that enclosed between each section was calculated and eventually the mineral deposits was determined. Detail exploration results show that the Tajar feldspar deposit have 99286 m3 volume and 258145 tons deposit. Tajar feldspar deposit is sodic type and their mineral composition is oligclase to albite.
