Investigation of trace elements and rare earth elements geochemistry in Goret Pb-Zn deposit Kelardasht region (Central Alborz)

Base-metals sulfide mineralization in Galena and sphalerite forms with little amount of pyrite, in Mobarak and Elika formation have been occurred in the studied region. Chemically, all deposit phases have compositing hemogen region. Mineralization has been followed the fault general process in the region, and the main textures in the ore are vein texture and open space filing. Genetically, studied deposits are epigenetic. Field features essentially have resulted mineralogical investigations and geochemical surveys on trace elements and rare earth elements (REE), they have included ore metals source in sulfide Pb-Zn mineralization in Kelardasht region showed carbonate - hosted mineralized rocks (upper Paleozoic, lower Triassic) in deposit. In genetic relation between Pb-Zn mineralization in this deposit with Akapol monzonit quartz - monzodiorite intrusion (aged to upper Eocene - lower Paleocene), Were located near to studied Pb-Zn deposits, Akapol intrusion have played as required heating source that heated ore fluids. According to Eu negative anomalies in ore and host rock samples,and were seemed The source of hydrothermal fluids in the studied region have been the surface and atmospheric full - oxygen water (meteoric) have been warm through closing Akapol intrusion and have been solved the elements and then have been deposited them in the host rock fault crushes, cracks and joints, and then circulation in base-metals have enriched carbonate hosted units.
