Abstract

The focus of the study was to examine Ti, Co, Ni, Rb, Sr, Ag, Au, Tl, Th and U occurrence related to sulfur mineralization (galena, sphalerite, chalcopyrite and pyrite) in Kalkım Region lead-zinc ore deposits, Yenice (Çanakkale). Kalkım hydrothermal polimetallic ore deposits (Bağırkaçdere, Handeresi, Arılıdere, Çatalakdere, Çulfaçukuru and Fırıncıkdere occurrences) exist in the schist of the Karakaya Complex under the effect of Eybek Granidiorite and controlled by tectonic components. The ore deposits occur within the Biga Peninsula in terms of those complicated geological properties. The research compared trace-element content of sulfur minerals from different points of origin. We collected 35 metallic sulfur samples and analyzed with laser ablation inductively coupled plasma mass spectrometry for each sulfur mineral. This study enhanced our understanding of geochemical events related to sulfur mineralization and some trace-elements.

At the end of the research determined that these ore deposits occurred depending a scarnation activity. Results of the laser ablation analyzing on separated samples from these ore deposits at the close areas show us that chalcopyrite mineralizations include abundantly Ti, Co, Ni, Ag and few amount of Rb, Sr, Au; galena mineralizations include abundantly Tl, Ag and little amount of Ti, Co; sphalerite mineralizations include abundantly Tl, Ag, Rb and a few Sr, little amount of Ti, Co. But existence of Ti, Co, Ni, Au, Ag are so different at the pyrite mineralizations. In a word, different sulfur mineralizations of these different ore deposits at the same origin host to different trace elements. This also set light to which mineralizations can be worked for which trace elements being by-product.
