Investigation of the petrography and geochemistry of vein type Cu- Pb-Zn ore deposition in the Mahmutçavuş (Oltu/Erzurum)

Mahmutçavuş village and its province in Narman, the town of Erzurum, where is observed cu mineralization was utilized in geological and geochemical aspects. All values were related to mineralization from the MTA.Lithologic units observed in the study area, are composed tertiary old basic lavas, agglomerates and tuffs. Associated with mineralization and hydrothermal alterations which only occured in tuffs, are consisted of clay-gypsum-quartz-limonite- calcite, and clay-chlorite-quartz-calcite.Mineralization observed in the study area, is vein type, and consisted of chalcopyrite, pyrite, malachite, azurite and very rarely galena. values of the soil geochemistry studies were determined 7-3130 ppm Cu, 7-1830 ppm Pb, 9-2800 ppm Zn.Mineralization observed in the study area, after the volcanism and tectonic movements in oligo-miyocene , hydrothermal solutions using fractures, are established in the tuffs, which are similar to lithologic and fracture-controlled vein-type mineralizations.
