Özet:

Due to the Alp-Himalayan orogenous system, significant tectonic generations have occurred in Turkey. The Toros Orogenic Generation of these generations is observed together with the units of the Arab sheet in the Kahramanmaraş region. Dadağlı (Kahramanmaraş) is an important area located in the edge of the Arabian sheet. In this area, the units of the Seydişehir formation form the oldest litology. On this unit, Mesozoic carbonates come with angle incompatibility. In the Mesozoic old carbonates, which are displayed in the northern border, the bullet is also observed. Carbohydrate is formed by the vein type and epigenetic that develops in the broken and fractures of carbonate stones. Galenitis, sfaleritis, baritis, ghetto, piritis, serozyt, smitzonitis and gang also form quartic parogenesis. In geochemical analyses in samples in the Cevher zone, PbO is up to a maximum of 60%. In the field and microscopic examination of samples around the vesicular vein, carbonatization and sericitation are widely observed. In order to identify the geochemical change in the area, alteration geochemistry studies have been carried out. The indicators are calculated to be used in these studies. In the Cevher zone, the chloride-carbonatpirite index (CCPI) values are between 57,02-93,24 (medium: 81,26), the chemical decomposition index (CIA) values are between 4,57-81,92 (medium: 30,80) and the alteration index (AI) values are between 4,81-94,33 (medium: 45,06). The CIA values show that there is a low and middle-degree separation. In alteration geochemistry diagrams and microscopic studies, common types of alteration have been identified as carbonatization and serisitization.
