Karacaali iron mineralization located about 5 kms north of the city of Kirikkale, is mostly occurring as veins and to a lesser degree as impregnations within fractures and joints in rocks such as diabase, basalt and micro-gabbros. Furthermore, in one location it has been observed as magmatic brecciation. These host rocks to mineralization are affected by hydrothermal alterations. Mineral paragenesis consists mostly of magnetite and pyrite as majör constituents as well as lesser amounts of hematite, musketofit, chalcopyrite, bornite, pyrrhotite, fahlore (tetrahedrite-tennantite), marcasite, covellite, goethite, chromite and thuringite. Diagrams showing the distribution of major, trace and also REE in the studied samples, indicated possible hydrothermal origin of mineralization. As a conclusion, the mode of deposition (as veins), wallrock alterations, mineral paragenesis and the geochemical characteristics of major, trace and REE shows hydrothermal type of mineralization.
