Abstract (EN)
The Pöhrenk fluorite mineralization is one of the largest area in Central Anatolia and situated within the karstic and silicified carbonates of Lutetian age, bounded by a NE-trending fault. Based on the fluid inclusion data and Tb/La versus Tb/Ca diagram obtained from fluorites show that mineralization was developed between 78,1-363oC at the hydrothermal stage. Silicious solutions accompanied with the space filling fluorites in carbonaceous rocks contain significant amount of solute Si with F (fluorine). In addition, significant amount of clay minerals occurred during the fluorite process. The major clay mineral of kaolinite indicates that the environment was acidic. Depleted values of HFS and REE in fluorites compared to host rocks show that these elements were not affected by the ore bearing solutions and remained stable.
