ABSTRACT Sarıhıdır travertines and associated manganese mineralization are located in an area known as the Central Anatolian Volcanic Province (CAVP). The topic of the study, the Sarıhıdır manganese mineralization, was deposited in association with fault zones in this tectonically-active region. Paragenesis of the mineralization includes pyrolusite, rhodochrosite and goethite with gangue minerals of calcite and quartz observed. Diagrams drawn using major oxide and trace elements like Fe–Mn–(Ni+Co+Cu)×10, Fe-Si×2-Mn, Co/Ni vs Cu+Co+Ni, Si/Al, Na/Mg, Fe/Ti vs. Al/(Al+Fe+Mn), Co+Ni/As+Cu+Mo+Pb+V+ Zn and FeO–MnO2–10× MgO show the mineralization found in the region is sourced in the hydrothermal field. The low total REE values and LREE>HREE ratio indicate the effect of hydrothermal solutions. Additionally, Ce, Eu and Ceanom anomalies indicate the source of the mineralization was hydrothermal with oxic-anoxic formation environment. The Y/Ho ratio is mean 30.1 which is lower compared to hydrothermal fluids. Mean values are δ13CPDB 12.24‰ and δ18OPDB 10.87‰ indicating deposition from fluids with a deep CO2 component. In conclusion, the Sarıhıdır mineralization and travertine were determined to have formed about 50–53 ka (Upper Pleistocene) based on U-series age data, as fault-controlled, hydrothermal-sourced mineralization.

Sarıhıdır 锰矿化与钙华有关，土耳其安纳托利亚中部火山省

摘要 Sarıhıdır 石灰华和相关的锰矿化位于被称为中央安纳托利亚火山省 (CAVP) 的地区。该研究的主题是 Sarıhıdır 锰矿化，沉积与该构造活动区的断层带有关。矿化的共生作用包括软锰矿、菱锰矿和针铁矿，并观察到方解石和石英脉石矿物。使用主要氧化物和微量元素绘制的图表，如 Fe-Mn-(Ni+Co+Cu)×10、Fe-Si×2-Mn、Co/Ni vs Cu+Co+Ni、Si/Al、Na/Mg、Fe /Ti vs. Al/(Al+Fe+Mn)、Co+Ni/As+Cu+Mo+Pb+V+ Zn 和 FeO–MnO2–10× MgO 表明该地区发现的矿化来源于热液场。低总 REE 值和 LREE>HREE 比率表明热液溶液的影响。此外，Ce，Eu和Ceanom异常表明成矿来源为热液，具有含氧-缺氧地层环境。Y/Ho 比率平均值为 30.1，与热液流体相比较低。平均值为 δ13CPDB 12.24‰ 和 δ18OPDB 10.87‰ 表明来自具有深层 CO2 成分的流体的沉积。总之，根据 U 系列年龄数据，确定 Sarıhıdır 矿化和石灰华形成了约 50-53 ka（上更新世），作为断层控制的热液成矿矿化。
