“…For instance, Ni, Mn, Fe, Cr and V are relatively enriched under moist climate conditions, whereas Mg, Sr, K, Ba, Na and Ca are enriched under arid climate conditions (Cao et al, 2012). C-value as proxy for climatic prosses has been applied in previous studies (C-value = Σ(Fe+Mn+Cr+Ni+V+Co)/ Σ(Ca+Mg+Na+K+Sr+Ba)) (Zhao et al, 2007;Fu et al, 2016;Wang et al, 2017;Vd'ačný et al, 2019;Bal Akkoca et al, 2019;. The C-values for the Trabzon area range from 0.03 and 0.11 (on mean 0.06),…”

“…It is known that V is a redox-sensitive chemical element with a trend to be lesser concentrated in sediments principial oxic water (Lewan and Maynard, 1982). Thus, Mo content, Ni/Co and V/(V+Ni) ratios were used as paleo-redox proxies for defining the redox conditions (Vd'ačný et al, 2019). Wang et al (2017) suggested that Ni/Co ratios < 5 reflect an oxidation environment, range from 5 to 7, pointing out a weak oxidation environment, and > 7 reflect a reducing environment.…”

Geochemistry and Pb isotopic proof for sources of heavy metal(loid)s in Late Cretaceous sandstones from Eastern Pontides (NE Turkey)

Upper Cretaceous sedimentary rocks are widely exposed around Trabzon, Giresun and Gümüşhane in the eastern Pontides. The sedimentary rocks are mainly composed of sandstones and marls, and the thicknesses of these rocks range from 170 m to 400 m. This paper focused on Late Cretaceous sandstones of Trabzon, Giresun and Gümüşhane regions to identify the concentrations, sources, deposition environment and conditions of certain heavy metal(loid)s (Zn, Pb, Cu, Ni, As, Co, Mo and V). Enrichment factor (EF), geo-accumulation index (Igeo), Pollution index (Pi), Pollution load index (Pln), Pb isotope and multivariate statistical analysis were performed to elucidate the pollution levels and sources. The mean concentrations of Zn,

“…Since the weathering index values of the terrace sediments are higher, the climate was likely more humid in the study area a few hundred years ago. In addition, the composition and distribution of some trace and major elements in sedimentary rocks may disclose the paleoclimatic variations (Hu et al, 2017;Vd'ačný' et al, 2019). Cao et al (2012) suggested that Mn, Fe, Cr, Co, Ni and V are relatively enriched under humid conditions.…”

There are minor geochemical differences between Harşit Stream bed and terrace sediments, and these can be owing to the impacts of climatic differences and chemical weathering rather than source rock composition. The bed sediments have lower average SiO 2 , Al 2 O 3 , Fe 2 O 3 , K 2 O, TiO 2 and MnO concentrations than terrace sediments, but higher concentrations of MgO, CaO and Na 2 O. The rare earth element (REE) distributions, Eu/Eu*, (Gd/Yb) N , La/Th and (La/Yb) N ratios of the bed and terrace sediments indicate that they derived from a mixture of 3% granodiorite + 50% gabbro + 47% felsic tuff and 5 % granodiorite + 37% gabbro + 58% felsic tuff, respectively. The CIA, PIA, WIP values and ICV, Rb/Sr ratios indicate that the bed sediments are lowly weathered and terrace sediments are lowly to moderately weathered. The distribution of C-values and Sr/Cu ratios indicate an arid to semiarid climatic conditions for the bed sediments and an arid to semi-moist climatic conditions for terrace sediments. During weathering of the mixed source rocks, Na indicates the greatest loss for the bed and the terrace sediments, and Pshows the lowest loss for both of sediments. The average of Si, Al, Na, K and Mn exhibits more loss in bed sediments than terrace sediments, the Fe, Mg, Ca and P exhibits less loss in bed sediments than terrace sediments.

The geochemistry of Late Cretaceous sandstones and shales in the Anambra basin has been investigated by relatively few subsurface data-based studies, thus, there is a need for subsurface geochemical characterisation of the basin's fill provenance, tectonics, and palaeo-conditions (source rocks palaeo-weathering, palaeo-climate, and palaeo-redox). This paper presents the geochemistry of sandstones and shales from cored sections (n ¼ 10) of the Amansiodo_1 well (located in the Anambra basin) with the intent of unravelling the provenance, tectonic setting, and palaeo-conditions. Major elements (n ¼ 10) and the trace element concentrations of Sc, Be, V, Sr, Y, Zr, and Ba were obtained using fusion inductively coupled plasma. Trace (n ¼ 24) and rare earth elements (La,
