Mining Geology of the Lead-Zinc Ore Mineralizations of Altınoluk, Çanakkale
ABSTRACT: Çanakkale Altınoluk (Papazlık) Pb-Zn mineralization is observed in amphibole-gneiss andmarbles of Fındıklı Formation, generally concordant with the host rocks and in fault zones whichintersect the host rocks.Ore minerals composed of galena, pyrite, chalcopyrite, sphalerite, phyrrothite, gold, hematite,rutil, ilmenite and other ores of replacement products.Ore samples include; 89 - >10000 ppm Pb, 129 - >10000 ppm Zn, 24 4136 ppm Cu, 0.31 6.79 % Fe, 71 2479 ppm Mn, 189 514.30 ppb Ag and 0.6 76513 ppb Au.From the geostatistical studies performed on ore and host rock samples; element assemblagesof Ti, Cr, Mg, Ca, Sr, Al represent the basic rocks and carbonates, Na, K, Rb, Ba representthe possible late hydrothermal stage, and Pb, Cu, Ag, Fe, ±Mn, ±Ni, ±Zn, ±Au represent themineralization.High ratio of Cr, Ti, Ni and Co element contents which are determined in the ore and hostrocksindicate the probable volcano-sedimentary characteristic of pre-metamorphism succession.In this study, the obtained data point out the primary source of the mineralization can besupposed to SEDEX type (Exhalative Sedimentary Type) enrichments. Further metamorphismand deformations may lead to the present position of mineralizations. In addition, the effects oflate hyrothermal stage elements derived from granitic rocks exposed around the region, can carrytraces though in limited ratios on mineralizations.
