“…The chemical composition of clastic sediments is an important clue to their provenance (Armstrong‐Altrin et al, ; Cullers, ; Madhavaraju, ; Madhavaraju et al, ; Madhavaraju & Ramasamy, ; Madhavaraju, Ramirez‐Montoya, et al, ; Madhavaraju, Tom, et al, ; Perri, Critelli, Mongelli, & Cullers, ; Ramachandran et al, ; Taylor & McLennan, ).

“…It also helps to constrain the composition and evolution of the upper continental crust (McLennan, ; Taylor & McLennan, ). The elemental ratios of key trace elements, REE patterns, and the magnitude of Eu anomalies in sandstones and shales further provide useful information regarding provenance (Armstrong‐Altrin et al, ; Bhatia, ; Cullers, ; Feng & Kerrich, ; Madhavaraju, ; Madhavaraju, Ramirez‐Montoya, et al, ; Madhavaraju, Tom, et al, ; Madhavaraju et al, ; Nath, Kunzendorf, & Pluger, ; Ramachandran et al, ; Raza et al, ; Wronkiewicz & Condie, ; Young, Pitawala, & Ishiga, ).…”

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

et al. 2018

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.

“…The elemental ratios such as SiO 2 /Al 2 O 3 , Al 2 O 3 /Na 2 O, and K 2 O/Na 2 O have been used extensively by various authors to interpret sediment recycling and are considered as a proxy to infer detrital input (Armstrong-Altrin 2009; Madhavaraju et al 2016;Zaid 2013;Zaid et al 2015). These ratios are >6, >5, and >1, respectively, if the sediment recycling is high (Tapia-Fernandez et al 2017).…”

Textural and geochemical characteristics of late Pleistocene to Holocene fine-grained deep-sea sediment cores (GM6 and GM7), recovered from southwestern Gulf of Mexico

et al. 2018

View full text Add to dashboard Cite

Texture, mineralogy, geochemistry, and 14 C ages of two deep-sea sediment cores (GM6 and GM7) recovered in the southwestern Gulf of Mexico were investigated to infer their provenance and depositional condition. The sediments are enriched in fine-grained silt and clay and poor in sand content. Mineralogically, the sediments consist of quartz, calcite, smectite, and kaolinite. Based on the 14 C data, the age of the GM6 and GM7 sediment cores were calculated as 23,615 cal yrs. BP and 19,007 cal yrs. BP, respectively. The weathering indices such as chemical index of alteration (CIA), chemical index of weathering (CIW), and plagioclase index of alteration (PIA) in GM6 (56-69, 60-74, and 61-73, respectively) and GM7 (54-69, 57-76, and 55-74, respectively) cores revealed a moderate-to-high intensity of weathering. The rare earth element (REE) patterns suggested that the sediments were derived mostly by the weathering of intermediate rocks, exposed along the coastal regions of the Gulf of Mexico. The trace elemental ratios like V/Cr (<2), Ni/Co (<2), and Cu/Zn (<1), authigenic uranium content (<1), and Ce anomaly (Ce/Ce * ≤ 1) suggested that the sediments were deposited under an oxic condition, which was also revealed by the benthic foraminiferal assemblages throughout the GM6 and GM7 sediment cores.

“…Palaeoclimate is the climate of a certain stage in geological history and is of great significance for the resources exploration [43][44][45][46]. Chemical index of alteration (CIA) is usually adopted to reflect paleoclimate during the sedimentary period [47][48][49].…”

The study of the oil shale from Triassic Chang 7 oil layer in Ordos Basin is of great importance to oil and gas resources investigation. Based on systematic analyses of major elements and rare earth elements of twelve oil shale samples and grain size analyses of four sandstone samples from the Yishicun Profile in southern Ordos Basin, the elements characteristics and corresponding geological implications are discussed. The Al/Si and Si/(Si + Al + Fe) of oil shale samples are in small range, with the averages of 0.29 and 0.67, indicating that quartz is the main mineral and the oil shale deposits near terrigenous provenance. Rare earth elements of the oil shale illustrate the enrichment of light rare earth elements (LREEs) and deficit of heavy rare earth elements (HREEs). The Chondrite-and North American shale composite (NASC)-normalized distributing patterns manifested that the oil shale have been derived from the same terrigenous source and controlled by a similar sedimentary environment. The vertical variation of major elements and REEs show that the heterogeneity of oil shale samples is relatively low. By grain size analysis, the interlayer sandstone is the typical turbidite. The Chemical index of alteration (CIA) and (Fe + Mn)/Ti of the oil shale samples ranges in 65.02-78.09 and 6.60-25.82, respectively, indicating that during oil shale sedimentation, the paloeclimate is warm and humid with moderate chemical weathering and that there are obviously hydrothermal fliud activities. The correlation between δCe N and δEu N , total rare earth elements (ΣREE) and (Dy/Sm) N , implying that the diagenesis of oil shale is relatively low with middle diagenetic stage A period. The Ce anom of oil shale samples ranges from −0.094 to −0.049, suggesting that the redox condition of oil shale sedimentation is dominated by strong reducing condition, and the (La/Yb)n is from 1.3 to 2.1, manifesting the whole sedimentary rate of oil shale is relatively low. By the comparison with REEs distribution characteristics from surrounding potential provenance, the main provenances of Chang 7 sedimentation in southern Ordos Basin are from Yinshan Mountain and Qinling-Dabie Mountain.
