Mining geology of the lead-zinc ore mineralizations of Altnoluk,Çanakkale [Çanakkale-Altnoluk kurşun-çinko cevher oluşumlarnn maden jeolojisi]

Çanakkale altnoluk (papazlk) pb-zn mineralization is observed in amphibole-gneiss and marbles of fndkl formation,generally concordant with the host rocks and in fault zones which intersect 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 assemblages of ti,cr,mg,ca,sr,al represent the basic rocks and carbonates,na,k,rb,ba represent the possible late hydrothermal stage,and pb,cu,ag,fe,±mn,±ni,±zn,±au represent the mineralization. high ratio of cr,ti,ni and co element contents which are determined in the ore and host rocks indicate the probable volcano-sedimentary characteristic of pre-metamorphism succession. in this study,the obtained data point out the primary source of the mineralization can be supposed to sedex type (exhalative sedimentary type) enrichments. further metamorphism and deformations may lead to the present position of mineralizations. in addition,the effects of late hyrothermal stage elements derived from granitic rocks exposed around the region,can carry traces though in limited ratios on mineralizations.
