“…Thus, in this study, we investigated lithological, sedimentological, and geochemical data acquired from six outcrop sites (Figure 1c) to understand the Permian evolution of the Chaiwopu Depression. Our results build on recent studies that established the Permian basin-mountain system of the Bogda Mountains and adjacent sedimentary basins [26][27][28][29][30][31][32][33][34][35][36]. The intracontinental basin-mountain series on the southern CAOB formed mainly during the Late Paleozoic as a derivation of the closure of the Junggar Ocean [4,[16][17][18].…”

“…Each sequence contains several formations (Figure 2b), and those with different nomenclatures can be correlated over the southern Junggar Basin, Tuha Basin, and West Bogda Mountains. Here we summarize the general lithological and sedimentary characteristics of each formation, based on previous studies [18][19][20][21][22][23][24][25][26][28][29][30][31][32][33][34][35]58].

“…This corresponds to a subsidence inherited from the Early Permian [32], resulting from the relaxation of compression and isostatic rebound of crustal deformation, related to a high sedimentation rate (e.g., [67]). In this tectonic movement, distinct interbeds of the Jingjingzigou section, such as poorly sorted sandstone, conglomerate, or fining-upward sandstone layers, are likely derived from slump or flow deposition in a deep lacustrine transformation (e.g., [68]) or alluvial fan system on the paleo-Bogda Mountains [26,29].…”

The Chaiwopu Depression in the southern Junggar Basin is located between the West Bogda Mountains and the northeastern Tian Shan Mountains in northwest China. The intracontinental basin–mountain system was formed in the Central Asian Orogenic Belt during the Late Paleozoic. The Permian strata around the depression exhibits distinct variations, which provide significant information to understand its tectonic and depositional evolution. This study investigated six outcrop sites using lithological, sedimentological, and geochemical analyses. The representative lithology of the Lower Permian is submarine lava and pyroclastic flows on the northern margins and alluvial deposits near the southern margins. In the Middle Permian sequence, the extensive distribution of alternating shale and silt/sandstone with oil shale and carbonate indicates a lacustrine setting. The sediments are composed of felsic rock-forming minerals derived mainly from island arc settings. The source rock properties correspond to the Carboniferous volcanic terrain of northeastern Tian Shan. The Lower to Middle Permian source-to-sink system occurred in an incipient level of weathering and maturation, a simple recycling process, and arid to semi-arid climatic conditions. The characteristics and changes of the depositional environment and provenance can be understood in terms of implications of tectono-paleogeographic evolution associated with the West Bogda rifting and uplift.

“…Shi et al combined sedimentological and geophysical methods such as field section measurements, core analyses, well logs, and seismic section interpretation to study the sedimentary evolution from the middle Permian to the early Triassic. In addition, provenance analysis was performed for the sediments from both flanks of the Bogda Mountain [19]. Shi et al used the outcrops in the north rim of the Bogda Mountain, cores, seismic, drilling, and logging data of the Fukang and Jimusar sag to illuminate the middle Permian-lower Triassic stratigraphic distribution, characteristics of sedimentary facies, and climate change in the Bogda region.…”

In recent years, the studies on fine-grained sedimentation mainly focus on the rock type, sedimentary environment, sedimentation, and sequence stratigraphy, while those on the relationship between sedimentary environment and lithofacies development are rare. However, a clear understanding on the relationship is of great significance to the muddy shale oil and gas exploration. This paper studied the muddy shale of semideep and deep lacustrine facies in the lower submember of Member 3 of Shahejie Formation in FY-1 Well, Dongying Sag, Bohai Bay Basin, East China. Based on geochemical data, the sedimentary environment media conditions and vertical changes of this submember were analyzed by means of core description, thin section authentication, X-ray diffraction (XRD), and other technologies, and the relationship between sedimentary environment and lithofacies development was discussed. The results show that this environment underwent three stages and is featured by cyclicity. From the bottom up, it experienced the semideep, deep, and deep/semideep waters under the relatively dry-cold/relatively warm-wet, warm-wet, and warm-wet/relatively warm-wet paleoclimates, respectively. Correspondingly, the paleoredox transited three stages from reducibility to high reducibility to high reducibility/reducibility; the paleosalinity changed from saline water to brackish water to brackish/saline water. Paleoproductivity was low/relatively high at the beginning, then became high, and finally relatively high. In this submember, the lithofacies primarily includes organic-rich mudstone, organic-rich lime mudstone, organic-rich lime-bearing mudstone, and organic-contained argillaceous limestone/lime mudstone. The sedimentary environment controls the mineral composition and content in the lithofacies and thus determines the lithofacies types. Meanwhile, the cyclicity of environmental change not only leads to that of the lithofacies development but also affects the positions of the lithofacies and its assemblages in sequence stratigraphic framework.

“…. Traditionally, in provenance studies, detrital zircon grain ages are compared with ages of probable source terranes, which delivered sediments to the depositional basin (Margalef et al, 2016;Shi et al, 2020;Tong et al, 2019;Wang, Wu, et al, 2018). On the other hand, numerous studies have proved that U-Pb dating of detrital zircon grains is a useful tool to reconstruct the tectonic evolution of a sedimentary basin, as well as to infer sediment pathway (Chaudhuri, Banerjee, & Le Pera, 2018;Gärtner et al, 2016;Kang et al, 2019;Pulsipher & Dehler, 2019;Saha, Burley, & Banerjee, 2018;Zhao et al, 2020).…”

Microtexture and U–Pb geochronology of detrital zircon grains in the Chachalacas beach, Veracruz State, Gulf of Mexico

trace element concentrations, and U-Pb geochronology of detrital zircon grains recovered from the Chachalacas beach in the western Gulf of Mexico were investigated to infer palaeoenvironmental conditions. The mineralogy of bulk sediments revealed the presence of both chemically stable (titano-magnetite, zircon, and quartz) and unstable (amphibole and K-feldspar) minerals. The zircon grain microtextures or surface features were grouped as two types: (a) mechanical origin and (b) mechanical and chemical origin. The mechanical surface features such as V-marks, arc shaped, and meandering steps indicate a high-energy littoral and sub-aqueous marine environment. The chemical surface features like solution pits, precipitation, solution crevasses, adhered particles, and silica pellicle revealed a silica saturated marine environment. The well-rounded zircon grains with bulbous edges are characterized by long transport and aeolian origin. The Th/U ratio, a negative Eu (Eu/Eu* = $0.08-0.72) and positive Ce (Ce/Ce* = >1) anomalies in the chondrite-normalized REE patterns of all zircon grains suggested that they primarily formed from magmatic processes. The detrital zircon grain U-Pb ages showed a wide variation from Cenozoic to Proterozoic with an abundance of Cenozoic ages ($1.59-64.3 Ma; n = 44), interpreted as mixing of beach sediments by a longshore current. The comparison of zircon grain ages of this study with ages reported from the source terranes revealed that the likely source for Cenozoic zircon grains was the Eastern Alkaline Province of Mexico. Similarly, the Mesozoic ($68.5-241.9 Ma) and Palaeozoic ($253.2-284.8 Ma) zircon grains in the Chachalacas beach were possibly derived from the Valle de Huizachal and Mesa Central provinces. Proterozoic ages from $574 to 1846 Ma indicated a probable contribution from the Oaxacan and Chiapas Massif complexes, which are dominated by Grenvillian basement rocks.
