REE and trace element geochemistry of vein type Pb-Zn Deposits: Dadağlı (Kahramanmaraş)

Abstract

Prior to Neothetys' closure, it may be observed in the Kahramanmaraş region in conjunction with the Taurus Orogenic Belt and Arabian Plate units. One of these bands, the marginal fold belt of the Arabian plate, is where the Dadağlı Pb-Zn mineralization is also observed. The oldest lithology in this area is made up of units from the Seydişehir formation. This unit is overlained in an angular unconformity of Mesozoic carbonates. In the fractures and fissures of carbonate rocks to the north of Dadağlı, there are vein type and epigenetic Pb-Zn mineralizations. Galenite, sphalerite, barite, goethite, pyrite, cerusite, smitzonite, quartz, and calcite are formed as gangues throughout paragenesis. Zn ranges from 77.19 to 1200.10% and Ag ranges from 6.20 to 59.17% in the ore zone samples that were used for the trace element analyses. Some of the samples that were compiled include a significant amount of Sc. The ore zone has low concentrations of these elements, according to REE analyses. When compared to heavy rare earth elements (HREE), it may be claimed that light rare earth elements (LREE) are richer. The Dadağlı Pb-Zn mineralization's characteristics are revealed by the obtained geochemical concentrations.
