In the study area, HFS elements showed relatively immobile behavior in different alteration zones at the Kozö ren district.…”

“…The Eu anomaly may indicate origin, mobility, or fractionation. Eu 2+ is mobile and removed from feldspar in parent rocks by hydrothermal fluids (Honty et al, 2008;Karakaya et al, 2012;Genna et al, 2014). In the evolution of magmatic rocks, the negative Eu anomaly reflects plagioclase fractionation in source rocks (Temizel and Arslan, 2009;Maurice et al, 2013).…”

Because of their geochemical properties, the Ç akmaktepe (Us°ak) kaolin deposits have been considered as primary. New sedimentological, mineralogical, and geochemical data suggest that the Ç akmaktepe kaolins are secondary deposits of sedimentary processes after hydrothermal alteration of the source rocks. The kaolins in the Ç akmaktepe deposit were formed from the hydrothermal alteration of calcalkaline Karaboldere volcanics (KBV). The kaolinized materials were then reworked and accumulated in a lacustrine basin. The argillic alteration zones were associated with faults, and lateral zonation of minerals was observed in the KBV. Smectite was the major phyllosilicate in the 'outer zone'. The alteration mineralogy of the 'inner zone' was similar to that of the Ç akmaktepe kaolins and consisted mainly of kaolinite with minor amounts of smectite and alunite. The trace-element abundances in the kaolinized volcanics and the Ç akmaktepe kaolins indicated hypogene conditions. The d 18 O values of the Ç akmaktepe kaolins ranged from 0.2 to 5.92%, which indicated that the Ç akmaktepe kaolinites were formed at temperatures between 92 and 156ºC, and the dD values ranged from À91.68 to À109.45%. The irregular edge-to-face morphology, the variation in grain-size, a few broken crystals of kaolinite, the deficiency of dissolution-replacement and crystallization mechanisms, and the the low sphericity, very angular, and poorly sorted quartz crystals in the kaolins all result from transport processes. The sedimentary structures, including trough cross-lamination, tool marks, and load casts, indicate transportation by turbulent waters and deposition of kaolin layers in a shallow lake.

The study area located in the western part of the Eastern Pontides, NE Turkey, represents the eastern part of the metallogenic province of the Black Sea region. The soil, water, and some mosses from the area contain heavy metal pollution from the mines and tailings of the abandoned and partially active massive sulfide deposits and their host rocks. The surface/subsurface/underground ore bodies generally cause the acidification of groundwater and the enrichment of heavy and toxic trace metals (Cu, Zn, Cd, Fe, As, and Pb) in the water, soil, and mosses. The mosses are Rhabdoweisia crispata, Pohlia nutans, and Pohlia elongata. R. crispata is a newly reported plant in Turkey, and the abovementioned moss species are observed especially where the toxic element contents of the water and soil are enriched. The mosses are sensitive to the trace metals and thus accumulate metal ions, predominantly Fe, Al, and Mn, which are apparent in the interaction between the water and roots. R. crispata is a better accumulator of trace metals and some major elements than the other mosses. R. crispata is therefore suitable for use in the recovery of polluted soil and water affected by acid mine wastewater from active and/or abandoned mining sites in the NE of Turkey.
