Cu-Pb Mıneralızatıon Near Soğucak (Iskilip-Çorum) And Its Genesıs

This study was prepared as Master Thesis in Mineral Deposits-Geochemistry Programme of the Geological Engineering Department of the Science Institute of Istanbul University during 2003-2006.

There are two main rock groups in the study area. They consist of volcanic units such as andesite, rhyolitic tuff, aglomerate and volkanic sandstone all of which constitute the basement of the study area and overlying conglomerate, sandstone, siltstone, gypsum, gravel, sand, clay as sedimantary units.

The Kızılırmak formation of Upper Miocene age comprising red pebblestone and sandstone, uncomformably overlies Eocene volcanic units of the Bayat formation. The gypsiferous Bozkır formation of Upper Miocene age that is concordant and transitive with Kızılırmak formation. Bozkır formation is the second sedimantary unit of the study area. The youngest unit in the study area is Quaternary alluvial deposits.

In order to study copper-lead mineralization which occurs as veins or veinlets in silicified and brecciated zones and elucidate its genesis, collected rock samples were examined in polished and thin sections at MTA laboratories. A total of 49 rock samples collected through 3 trenches cut in silicified zones were chemically analyzed for Cu-Pb-Zn-Mo-Au-Bi-Sb-As. Genarally, Cu proportion was identified between 21-1015 ppm and Pb was identified between 50-5200 ppm. XRD and Fluid inclusions studies were achieved at XRD Labratory and Fluid Inclusions Labrotory of Istanbul University. Homogenization temperature (Th) was identified as 226^oC and Salinity (wt% NaCl equivalent) was identified as 11%. When these results were compared with similar ore deposits types it was seen that identified data characterized epithermal system.
