"Geochemical Investigation of Hatay Gold Deposits"

Abstract: In this paper, the important geochemical features of the auriferous quartz veins and sulphide lodes aswe as surronding alteration zones and the host rock were investigated in detail.Work to date has shown that the surrounding alteration zones of the veins and the host rocks were affected by hydrothermal fluids in various degrees but in decreasing values towards to the host rocks.The alteration zones were found to be enriched gold and silver, whereas the host rocks, diabase dikes and gabbroswere found to be affected by hydrothermal flued but free of gold and silver at all, IAnother results of this study is that to show the geohemical differences between trace and rare earth elements (REE)contents of the auriferous quartz veins and sulphide lodes.It is found that the auriferous sulphide lodes contain Sc, Co, Rh, Cd, In, Sn, Sb, I, Cs, Ba, Hf, Ta, W, Ir, Pt, La,Ce, Pr, Tb, Ifo, Yb, Lu and In various grades, beside common elements with auriferous veins, whereas the auriferousveins contain some Ba, Rb, Y, Zr, Nb, Cd, Tm, Po, Eu, Ru, Sr, Th, Pa, Re and Fr, which are never met in thesulphide lodes.Furthermore, 38 elements were detected in various combination in gold particles, which are mainly found in quartz,arsenopyrîtê, chalcqpyrite, sphalerite şnd pyrite as native or disseminated grain.According to the stated differences, besides the geological and mineralogical differences, it is surely believed that thesources of the auriferous quartz veins and the sulphide lodes should have been different.
