“…The appearance of paleosols indicates variation of the depositional environment. The calcrete beds in the reddish-brown paleosols indicate that the calcium in the soil dissolved and moved vertically, which is controlled by pedogenesis via seasonal precipitation in a semi-arid climate [43,44]. Type II paleosols developed in moderate to poorly drained conditions with a gleying process.…”

“…The mottles in the type V paleosols indicate iron mobilization in the paleosol during the gleying process with alternating saturated and better drained conditions controlled by falling water tables (Kraus and Hasiotis, 2006). The calcrete beds and cutans in the type VI paleosols indicate seasonal precipitation that facilitated a leaching and subsequent illuviation process of calcium and manganese from the paleosol matrix in a semi-arid climate [43][44][45][51][52][53].…”

The limited knowledge of Late Cretaceous terrestrial environments and their response to tectonic events in mid-latitudes can be addressed through continental basin deposits such as paleosols. Paleosols have been discovered in the Late Cretaceous Yaojia Formation in the southern Songlaio Basin and are recognized by evidence of soil structures controlled by pedogenesis. Sedimentary facies research on red paleosols was conducted on the Late Cretaceous Yaojia Formation in the outcrop of the southern Songliao Basin to interpret the depositional environments and tectonic significance of red paleosols during the greenhouse period. Mudflat, lake margin, and shallow lake depositional environments in a semi-arid climate are interpreted from the outcrops based on sedimentary descriptions and interpretation as well as geochemical and micromorphological analyses of paleosols in outcrops. We reconstructed the paleoenvironmental and paleoclimatic conditions through the paleosols in the mudflats and lake margin. The red paleosols in the mudflats and lake margin deposits formed in a stable landscape influenced by the tectonic uplift of the Songliao Basin, which is considered as new important evidence for tectonic uplift influenced by the collision of the Okhotomorsk Block with East Asia. The tectonic uplift process in East Asia is identified from the evolution of the depositional environments and drainage conditions inferred from different types of paleosols. Thus, the paleosols-bearing red bed deposits in outcrops provide an important contribution of the Late Cretaceous terrestrial paleoclimate and the tectonic setting research.

“…This section has a darker colour and complicated lithological alternance. It has layers of sand that are brownish and grey‐green, respectively, showing the development of normal and subaqueous distributary channels, which are typical characteristics of the delta front sub‐facies (Zhang et al ., 2017, 2018a; Wang et al ., 2019). In conclusion, the complex depositional environments and frequent facies alterations in the HX borehole make it difficult to conduct grain‐size analyses.…”

For many years, researchers have used the decomposition of grain‐size distributions to acquire critical information on provenances, transport dynamics and depositional environments. This study presents a novel decomposition method, termed the universal decomposition model, for analysing grain‐size data. The universal decomposition model unifies single‐sample unmixing and end‐member modelling analysis approaches and overcomes their respective limitations. To evaluate the effectiveness of the universal decomposition model, an artificial dataset and borehole data from the west Weihe Basin were analysed. Results indicate that the universal decomposition model algorithm performs proficiently on both datasets. Correlation analysis was employed to compare the abilities of universal decomposition model, single‐sample unmixing and end‐member modelling analysis to extract minor signals, with universal decomposition model and single‐sample unmixing exhibiting greater proficiency. Furthermore, the universal decomposition model provides a broader perspective for contrasting single‐sample unmixing and end‐member modelling analysis. The study highlights the inadequacy of the statistical method for determining the optimal number of components and summarizes an empirical approach. Moreover, disregarding the potential diversity in component shapes of real‐world sediments has been demonstrated to be a sub‐optimal design. Finally, this article presents results of a new investigation into the geological significance of sediment grain sizes revealed by various analytical methods that suggest that the universal decomposition model has enormous potential in reconstructing paleoenvironment.
