    INVESTIGATION OF STATISTICAL RELATIONSHIPS BETWEEN Au, Ag, As, Ba, Cd, Cu, Fe, Pb, S, Sb, and Zn ELEMENTS OF ANTIMONY DEPOSIT IN NW CAMARDI -NIGDE (TURKEY)
    (STEF92 TECHNOLOGY LTD, 2016) Yalcin, Fusun; Tumuklu, Ali; Bortas, Serdar C.; Ilbeyli, Nurdane
    In antimony deposit in NW Camardi-Nigde (Turkey), antimony produced by underground mining in the 1970s. 3 galleries are connected to each other and 2 galleries are independent. According to the geochemical and mineralogical-petrographical investigations, stibnite mineralization in the vein rocks may be about 70-80 wt %. In geochemical analysis of ore and hosted rocks from both inside and outside of the gallery, correlations between Sb and Au, Ag, As, Ba, Cd, Cu, Fe, Pb, S and Zn were investigated. In the correlation values, 50% and upper meaningful relationships have been taken into account. Accordingly, 7 positive relationships between the elements were determined and no meaningful negative correlation could be detected. Positive correlations are Zn-Cd: 0,84; Pb-Ag: 0,71; Pb-Cd: 0,65; Zn-Pb: 0,56; Fe-As: 0,54; Sb-S: 0,50 and Ag-Cd: 0,50. According to these results, Zn and Cd elements have the most powerful and Ag and Cd elements have the lowest significant positive correlation. There are numerous ore outcrops and quarries containing sphalerite (ZnS) and Galena (PbS) located in the area. Only Pb/Zn ores produced in these fields and Cd and Ag have been ignored. Cd and Ag potential in the area can be exposure by detailed geological explorations.

    Statistical approach by factor and cluster analysis on origin of elements from the Hamit Plutonic (Turkey) rock samples
    (Maden Tetkik Ve Arama Genel Mudurlugu-Mta, 2019) Yalcin, Fusun; Nyamsari, Daniel G.; Ilbeyli, Nurdane; Battaloglu, Rifat
    The Hamit pluton forms part of the Central Anatolian Crystalline Complex. It is located N-NE of Kaman (Kirsehir). It covers an area of about 120 km(2). The geochemical contents of 63 rock samples collected from this pluton were analyzed for their origin, homogeneity and relationship with crustal rocks. Their element contents were determined by using X-Ray Fluorescence spectroscopy. The samples were divided into 2 major groups based on their similarities: Group 1 contained 63.5% of the samples and indicated they were formed from melts whose contents might have evolved greatly due to crustal assimilation; while the 36.5% of samples belonged to Group 2, and show minimal evolution of the melt. According to the variation in K/Rb ratio versus SiO2 and the Rb/Zr versus SiO2 the initial melt had experience great evolution due to crustal assimilation. The initial melt is considered to have contained most of SiO2, TiO2, Fe2O3, MnO, MgO, CaO, P2O5, Sr, Zn, Cu, Ni, Co, Cr, Ba, Nd, Sc and V that formed the pluton, while majority of the Al2O3, Nb, Zr, U, Th, Pb, Ga, Rb, Ce and La are considered to have been derived from crustal contamination, and almost all of Na2O, K2O and Y are considered to have originated from crustal assimilation.
