“…It is widely considered that some major oxides (e.g., SiO 2 , Al 2 O 3 , CaO, MgO, Fe 2 O 3 , and K 2 O) abundances of the detrital rocks are controlled by different types of tectonic environment (Armstrong‐Altrin et al, ; Bhatia, ; Hu, Li, et al, ; Moosavirad et al, ; Roser & Korsch, ; Tao et al, ). The identification diagrams according to major elements were put forward by Bhatia () and Roser and Korsch (), which had been widely applied to discriminate the tectonic setting of the sedimentary basin.…”

“…Numerous studies have certified that the chemical components of terrigenous sediments are closely connected with the tectonic setting of source area (Bhatia & Crook, ; Fatima & Khan, ; Moosavirad, Janardhana, Sethumadhav, Moghadam, & Shankara, ; Sun, Gui, & Chen, ), which have been extensively applied to analyse the provenance (Madhavaraju, ; Sun et al, ; Tawfik, Ghandour, Maejima, Armstrong‐Altrin, & Abdel‐Hameed, ; Zaid, ) and constrain the tectonic setting (Armstrong‐Altrin et al, ; Armstrong‐Altrin, Nagarajan, Balaram, & Natalhy‐Pineda, ; Moosavirad et al, ; Tao, Sun, Wang, Yang, & Jiang, ) of sedimentary basins in the past 20 years. To deduce the tectonic setting, previous studies are continuously using the traditional tectonic identification diagrams put forwarded by Bhatia () Fe 2 O 3 T + MgO vs. TiO 2 , Fe 2 O 3 T + MgO vs. Al 2 O 3 /SiO 2 , Fe 2 O 3 T + MgO vs. K 2 O/Na 2 O) and Bhatia and Crook () La–Th–Sc, Th–Co–Zr/10, Th–Sc–Zr/10).…”

The geochemistry and detrital zircon geochronology of the Quemoco sandstones from the Woruo Mountain area, North Qiangtang Basin, are analysed to discriminate their provenance and tectonic setting. The sandstones were classified as litharenite according to their geochemical data. The index of chemical variability and SiO2/Al2O3 ratio values suggest that the compositional maturity and recycling are weak to moderate. The weathering indices, such as chemical index of alteration, plagioclase index of alteration, and chemical index of weathering, and A–CN–K (Al2O3–(CaO* + Na2O)–K2O) ternary plot reflect that the source areas have undergone a weak degree of weathering. The TiO2 versus Zr, La/Th versus Hf, and Co/Th versus La/Sc bivariate diagrams and multimajor elements discrimination diagram of Quemoco sandstones indicate that the provenances were primarily derived from felsic igneous rocks and may also have less intermediate igneous source rocks. The paleocurrent data and low composition and textural maturity of the Quemoco sandstones suggested that the provenances are mainly from the southwest of the study area and with proximal source features. The U–Pb ages studied here could be divided into 8 groups: 206–219 Ma, 268–283 Ma, 446–630 Ma, 700–970 Ma, 1006–1346 Ma, 1457–1843 Ma, 2087–2214 Ma, and 2331–2587 Ma. The provenances are mainly from the Central Uplift Belt and surrounding of the study area according to the detrital zircon ages and rare earth element parameters, which are composed of Late Triassic tuff, Permian basalt, Early Ordovician granite, Cambrian granite gneiss, and Precambrian crystalline basement. Two multidimensional tectonic discrimination diagrams based on major elements show a complicated tectonic setting composed of a collision, rift, and minor arc setting for the Quemoco sandstones, which is consistent with the nature of a rifted margin during the late Late Triassic.

“…The chemical composition of siliciclastic sedimentary rocks can be related to their source region chemical composition (e.g., Madhavaraju and Lee, 2010;Nagarajan et al, 2011;Moosavirad et al, 2011;Hofer et al, 2013;Armstrong-Altrin, 2014;Armstrong-Altrin et al, 2015a, 2015b. In order to infer the provenance of siliciclastic rocks, several major, trace, and rare earth element-based discrimination diagrams have been proposed by various authors (e.g., Roser and Korsch, 1988;Floyd et al 1989Floyd et al , 1990; McLennan Taylor and McLennan (1985).…”

“…The petrography and geochemical composition of clastic rocks provide valuable information regarding their provenance and tectonic setting (Cingolani, Manassero, & Abre, ; Jafarzadeh & Hosseini‐Barzi, ; McLennan & Taylor, ). Geochemical studies on clastic rocks have long been used to identify the provenance characteristics (Armstrong‐Altrin et al, ; Concepcion et al, ; Madhavaraju, ; Madhavaraju & Ramasamy, ; Moosavirad, Janardhana, Sethumadhav, Moghadam, & Shankara, ; Ramachandran et al, ; Raza, Ahmad, Khan, & Khan, ; Srivastava, Randive, & Khare, ; Velmurugan et al, ). The geochemistry of clastic sedimentary rocks is considered a powerful tool in the study of provenance, tectonic setting, and palaeoclimatic conditions (e.g., Absar, Raza, Roy, Naqvi, & Roy, ; Bhatia, ; Madhavaraju & Lee, ; Nesbitt & Young, ; Taylor & McLennan, ).…”

Detrital zircon record of Mesozoic volcanic arcs in the Lower Cretaceous Mural Limestone, northwestern Mexico

The northwestern part of Mexico, southern Arizona, and southern California witnessed extensive arc magmatism during Late Triassic to Early Cretaceous. Here, we present results from petrography, whole‐rock geochemistry (major and trace including rare‐earth elements), and detrital zircon geochronological studies that were carried out on sandstones and shales of the Mural Limestone exposed in the Rancho Bufalo area. Based on the petrography, sandstones are classified as sublitharenite, litharenite, feldspathic litharenite, and lithic arkose. The sandstones contain higher proportion of monocrystalline quartz than polycrystalline quartz. Sandstones and shales from the various members of the Mural Limestone show large variations in major and trace elements concentrations. The average concentrations of ΣREE (total ΣREE) are lower in sandstones than in shales. The chondrite‐normalized REE patterns of the sandstones and shales are moderately fractionated with light REE (LREE) enrichment relative to heavy REE (HREE) and with flat to slightly depleted HREE patterns. The chemical index of alteration values and A–CN–K relationships of sandstones indicate low to moderate intensity of weathering in the source region; however, shale samples suggesting the source rocks were subjected to moderate intensity of chemical weathering. The chondrite‐normalized REE patterns, Al2O3/TiO2 ratio, elemental ratios like Cr/V, Y/Ni, and Eu‐anomaly (Eu/Eu*), and bivariate plots suggest that the sandstones and shales were derived mainly from felsic source rocks. Detrital zircon U–Pb geochronology of sandstones from Fronteras, Rancho Bufalo, and Cerro La Ceja members of the Mural Limestone show five main groups of detrital zircon age populations: (a) Proterozoic, (b) Palaeozoic, (c) Triassic, (d) Jurassic, and (e) Early Cretaceous. Our study suggests that continental volcanic arcs in northwestern Mexico, southern Arizona, and southern California served as the provenance for the Late Triassic‐Jurassic detritus, whereas the Early Cretaceous zircon grains were derived mainly from the active Alisitos volcanic arc along the northwestern coast of Mexico.
