“…A quartered fraction of each sample was impregnated with Araldite, cut into a standard thin section, stained with alizarine red to distinguish dolomite and calcite, and analysed by counting 400 points under the microscope (Gazzi-Dickinson method; Ingersoll et al, 1984). Sands were classified according to their main components (Q = quartz; F = feldspars; L = lithic fragments), considered where exceeding 10%QFL, and listed in order of abundance (e.g., in a litho-feldspatho-quartzose sand Q N F N L N 10%QFL; Garzanti, 2015). Very-low-to low-rank metamorphic lithics, for which protolith can still be inferred, were subdivided into metasedimentary (Lms) and metavolcanic (Lmv) categories.…”

“…Sand s were classification is based by on their main components quartz, feldspars and lithic fragments considered if exceeding 10%QFL (e.g., a sand is namedin a quartzo-lithico-feldspatho-quartzose sand if L > Q >F>L> 10%QFLQFL > F; Garzanti, 2016). Metamorphic grains were classified by protolith composition and metamorphic rank.…”

“…In this section we examine to what extent the lesson learned from our modern-sand perspective may be applicable to the analysis of an imaginary non-diagenetically altered ancient clastic wedge generated by analogous geodynamic processes, and discuss the insight gained and potential pitfalls associated with the classical approach postulating the existence of a direct link between sediment composition and plate-tectonic setting (Dickinson, 1985), versus an upgraded approach focusing specifically on the tectono-stratigraphic level of source terranes (Garzanti, 2016).…”

Abstract: We present a detailed sediment-provenance study on the modern Euphrates-Tigris-Karun fluvial system and Mesopotamian foreland basin, one of the cradles of humanity. Our rich petrographic and heavy-mineral dataset, integrated by sand geochemistry and U-Pb age spectra of detrital zircons, highlights the several peculiarities of this large source-tosink sediment-routing system and widens the spectrum of compositions generally assumed as paradigmatic for orogenic settings. Comparison of classical static versus upgraded dynamic petrologic models enhance the power of provenance analysis, and allow us to derive a more refined conceptual model of reference and to verify the limitations of the approach. Sand derived from the Anatolia-Zagros orogen contains abundant lithic grains eroded from carbonates, cherts, mudrocks, arc volcanics, obducted ophiolites and ophiolitic mélanges representing the exposed shallow structural level of the orogen, with relative scarcity of quartz, Kfeldspar and mica. This quartz-poor petrographic signature, characterizing the undissected composite tectonic domain of the entire Anatolia-Iranian plateau, is markedly distinct from that of sand shed by more elevated and faster-eroding collision orogens such as the Himalaya. Arid climate in the region allows preservation of chemically unstable grains including carbonate rock fragments and locally even gypsum, and reduces transport capacity of fluvial systems, which dump most of their load in Mesopotamian marshlands upstream of the Arabian/Persian Gulf allochemical carbonate factory. Quartz-poor sediment from the AnatoliaZagros orogen mixes with quartz-rich recycled sands from Arabia along the western side of the foreland basin, and is traced all along the Gulf shores as far as the Rub' al-Khali sand sea up to 4000 km from Euphrates headwaters.Reviewer #1: This is an excellent review of an intriguing complex modern sediment source-to-sink system that has not been studied in a comprehensive manner prior to...

“…The compositional and geochronological signatures of detritus derived from an orogenic domain, which depend primarily on the lithology and time structure of source rocks and their evolution during progressive unroofing, provide an effective means to trace erosion processes in space and time (Garzanti, 2016). Any detrital component and any type of fingerprint (e.g., petrographic, mineralogical, geochemical, isotopic, geochronological) can be used as a provenance tracer to partition the sediment flux into its different sources (Padoan et al, 2011;von Eynatten and Dunkl, 2012), and hence to calculate average denudation rates in different parts of a river catchment once the total sediment load is known with reasonable accuracy Syvitski and Kettner, 2011).…”
