DEVELOPMENT OF PRECIOS STONES MINES IN IRAN, CASE STUDY: EXPLOITATION OF MEASURMENT POSSIBILITY OF AGAT AND JASPER MINERALS- SOLTANIEH AREA.

Jasper and agat mines have been recognized in the Soltanieh, about 56 km of north-eastern of Qom city and about 80 km of Tehran. Geologically, this region locates in Structural zonation of central Iran and Orumieh- Dokhtar volcanic belt, and that field had been studied, and there is (showing) evidence of precious stones and expensive mineral in the original of volcanic rocks of Orumieh- Dokhtar area. In the scattered outcrops of volcanic masses and sedimentary deposits of this rocks would be recognizable variety of valuable precious minerals. Regarding providing of geological maps in the scale of 1/2500 and gathering sample of minerals stones and sediments, it had been identified proportional concentration of jasper and agat in the five parts of this area. Economical potential had been confirmed to do different trace cutting and sections in these parts and preparatory extracting to open top, and it is estimated about 2500 tons of storage and possibility of extracting about 150 tones. In this paper has been tried to compare original of making above volcanic rocks to other part of Orumieh- Dokhtar belt toward north western to south eastern that would be included vast parts of Iran geology, it would be introduced other hopeful regions in southern parts.
