“…The SiO 2 /Al 2 O 3 ratio of sandstones is in the range of 3.09-6.48, and that of shale is in the range of 3.24-6.8. The Na 2 O/K 2 O ratios of sandstones and shales are low (0.91-1.91) and indicate the low degree of maturation of the Çamardl Formation (Table 2) (Pettijohn et al, 1972;Roser and Korsch, 1986;Fedo et al, 1995;Das et al, 2006;Paikaray et al, 2008).…”

“…The immobile elements such as Al 2 O 3 , Fe 2 O 3 , TiO 2, Th, Sc, Co, Zr, and REEs are particularly useful for provenance interpretations. Being immobile phases in aqueous systems, these elements retain the original source concentration within the shale (Bhatia, 1983;Blatt, 1985;Taylor and McLennan, 1985;Condie, 1993;Hayashi et al, 1997;Kasanzu et al, 2008;Paikaray et al, 2008). Whole-rock geochemistry is a useful tool for analyzing a tectonically complex region (Bhatia, 1983;Yan et al, 2007).…”

Geochemistry of Çamardı Formation sediments, central Anatolia (Turkey): implication of source area weathering, provenance, and tectonic setting

The upper Cretaceous-Eocene Çamardl Formation is exposed along the northern edge of the Ulukl la Basin (central Anatolia) and consists of turbiditic sediments. The sediment geochemistry has been studied in order to understand the provenance, source area weathering, and tectonic setting of the basin. Çamardl Formation sediments are characterized by low to moderate SiO 2 contents, variable abundances of major elements, and a relatively high proportion of ferromagnesian elements. Evidence from discrimination diagrams of sedimentary provenance, tectonic setting, major element geochemistry and Sc/Th, Cr/Th, Co/Th, Zr/ Sc, La/Sc, La/Co, Cr/Sc, Y/Ni, and K/Rb values show that the Çamardl Formation sediments were derived from mafic, felsic, and intermediate sources. The chemical index of alteration (CIA: 57.63-78.11) revealed moderately weathered source rocks. Then major and trace element concentrations indicated deposition in an active continental margin and continental island arc settings.

“…Composition of major and accessory heavy minerals in sandstones provide crucial information regarding the provenance of sedimentary basins (Armstrong-Altrin et al 2012Arribas et al 2000;Caracciolo et al 2012;Critelli and Ingersoll 1994;Critelli and Le Pera 1994;Critelli et al 2003;Le Pera and Critelli 1997;Paikaray et al 2008;Saha et al 2010). Petrographic investigation of sandstone is widely used to infer tectonic setting, source rock composition, transportation and environment of deposition (Dickinson 1970(Dickinson , 1985Dickinson and Suczek 1979;Dickinson et al 1983;Ingersoll and Suczek 1979;Le Pera and Arribas 2004;Le Pera et al 2001;Zuffa 1985Zuffa , 1987.…”

This paper investigates the provenance of Middle Jurassic to Early Cretaceous sediments in the Kutch Basin, western India, on the basis of mineralogical investigations of sandstones composition (Quartz-Feldspar-Lithic (QFL) fragment), Zircon-Tourmaline-Rutile (ZTR) index, and mineral chemistry of heavy detrital minerals of the framework. The study also examines the compositional variation of the sandstone in relation to the evolution of the Kutch Basin, which originated as a rift basin during the Late Triassic and evolved into a passive margin basin by the end Cretaceous. This study analyzes sandstone samples of Jhumara, Jhuran and Bhuj Formations of Middle Jurassic, Upper Jurassic and Lower Cretaceous, respectively, in the Kutch Mainland. Sandstones record a compositional evolution from arkosic to subarkosic as the feldspar content decreases from 68% in the Jhumara Formation to 27% in the Bhuj Formation with intermediate values in the Jhuran Formation. The QFL modal composition indicates basement uplifted and transitional continental settings at source. Heavy mineral content of these sandstones reveals the occurrence of zircon, tourmaline, rutile, garnet, apatite, monazite and opaque minerals. Sub-rounded to well-rounded zircon grains indicate a polycyclic origin. ZTR indices for samples in Jhumara, Jhuran and Bhuj Formations are 25%, 30% and 50% respectively. Chemistry of opaque minerals reveals the occurrence of detrital varieties such as ilmenite, rutile, hematite/magnetite and pyrite, in a decreasing order of abundances. Chemistry of ilmenites in the Jhumara Formation reveals its derivation from dual felsic igneous and metabasic source, while those in Jhuran and Bhuj Formations indicate a metabasic derivation. Chemistry of garnet reveals predominantly Fe-rich (almandine) variety of metabasic origin. X-ray microscopic study provides the percentage of heavy minerals ranging from 3% to 5.26%. QFL detrital modes reflect the evolution of the basin from an active rift to a passive margin basin during the Mesozoic. Integration of results from QFL modal composition of the sandstones, heavy mineral analysis and mineral chemistry, suggests sediment supply from both northern and eastern highlands during the Middle Jurassic. The uplift along the Kutch Mainland Fault in the Early Cretaceous results in curtailment of sediment input from north.

The Late Miocene-Pliocene Aghajari Formation is exposed throughout the Folded Zagros Zone and consists of fluvial sediments. Aghajari Formation sandstones are characterized by low to moderate SiO 2 contents, variable abundances of major elements and a relatively high proportion of ferromagnesian elements. Evidence from discrimination diagrams of sedimentary provenance, tectonic setting, major element geochemistry, and Sc/Th, Cr/Th, Co/Th, Zr/ Sc, La/Sc, La/Co, Cr/Sc, and Y/Ni values show that the Aghajri Formation sediments were derived from felsic and intermediate sources. The chemical index of alteration (CIA: 59.2-77.14) revealed low to moderately weathered source rocks. The major and trace element concentrations indicate deposition in an active continental margin and passive continental margin settings.
