turkey’s eastern Anatolia Region is the oldest known mineral mining area of Maden and *** production in the Alacakaya field constitutes 50% of the country’s exports,and copper mines in the Maden region account for approximately 12% of the country’s copper *** is a risk of water pollution due to significant mine waste which affects the Inci and Maden *** water needs of many settlements are met from these streams,which run through these two mine *** study investigated the water pollution in the rivers.25 water samples were collected during the dry and rainy periods,and the Al,Cr,Cu,Fe,Li,Mn,Ni,Pb,Sr and Zn contents of these samples were examined in terms of *** of element concentrations and creation of spatial distribution maps were performed using ArcGIS *** distribution maps,correlation and cluster analysis indicate that the source of heavy metals observed in waters is mine *** heavy metal content of the samples is higher in the dry period,the high concentration values are obtained from the mine sites,the decrease in the concentrations throughout the flow during the rainy period,are indicators of the effect of the mines on the water *** a result of the comparison from the analysis results of water samples with World Health Organization(WHO),Environmental Protection Agency(EPA)and European Commission(EC)standards,the element values of Al,Cr,Fe,Mn,Ni and Pb exceeded the permissible values for *** concentrations of these elements for dry period samples are:0-6.411 mg L^(-1),0.006-0.235 mg L^(-1),0-13.433 mg L^(-1),0-0.316 mg L^(-1),0-0.495 mg L^(-1),0-0.065mg L^(-1),and for rainy period samples are 0-1.698mg/L,0-0.2 mg L^(-1),0-9.033 mg L^(-1),0-0.173 mg L^(-1),0-0.373 mg L^(-1),0-0.034 mg L^(-1),*** the waters in the region are polluted by heavy metals,it has been determined that there is no noncarcinogenic hazard as a result of the calculation of the hazard i

Pancarli Ni-Cu±(PGE)sulfide deposit occurs in the Neoproterozoic basement complex of the Bitlis massif,which is one of the Andean-type active continental margin fragments with arc-type assemblages represented by the Cadomian orogenic *** sulfides are associated with quartzo-feldspathic gneisses(country rock)and mafic intrusions(host rock).Composed of only semi-massive ore,the Ni-Cu±(PGE)sulfide deposit is a small-scale deposit,and it does not contain net-textured and disseminated *** mineral assemblage comprises pyrrhotite,pentlandite,and *** semi-massive ore samples contain 2.2 wt.%-2.9 wt.%Ni,0.8 wt.%-2.2 wt.%Cu(Cu/(Cu+Ni)=0.2-0.5)and 0.13 wt.%-0.17 wt.%*** Cu/Ni ratios(average 0.57)are consistent with the segregation of sulfides from a basaltic *** Pt+Pd100%S values of 0.08 ppm-0.89 ppm,relatively low Pt/Pd ratios of 0.2-1.4,and Pd/Ir ratios of 4.5-39 have also been *** values demonstrate that the magma reached S saturation before its emplacement and the mineralization with high Cu/Pd ratios formed by sulfides segregated from a PGE-depleted magma.δ^34S isotope values(average-3.1‰)of Pancarli sulfides are lower than mantle ***δ^34S value indicates contamination from surrounding *** the composition,remobilization style and magma type,the Pancarli Ni-Cu±(PGE)sulfide deposit is similar to the deposits associated with Andean-type magmatic arcs located in the convergent plate margin settings.
