TL;DR: In this article, the authors proposed a set of criteria for the recognition of seismites in sedimentological, structural and palaeoseismic studies, including the following: (1) soft-sediment deformation structures should occur in laterally continuous, preferably recurring horizons, separated by undeformed beds; (2) these deformation structure should be comparable with structures known to have been triggered by modern seismic activity; (3) the sedimentary basin should have experienced tectonic activity at the time when the deformations were formed; and (4) the intensity or

TL;DR: In this paper, a dataset of calcareous foraminifers was compiled containing the temporal distribution (biozone level) of 420 species belonging to 155 genera currently described from Strunian (latest Devonian) to basal Serpukhovian (Lower Carboniferous) key sections in southern China, and the presence of those species in eleven palaeobiogeographical units.

TL;DR: The lignite deposits of Kutch, India are stratigraphically referred to the Naredi Formation and considered to be Early Eocene in age as mentioned in this paper, and their lower age may extend to the late Lutetian.

TL;DR: In this article, the authors discussed the controlling factors of sedimentary evolution and palaeoclimate changes in Junggar Basin during the Jurassic period based on lithology, fossils and tectonic setting.

TL;DR: The quantitative lithofacies palaeogeography (QLP) as discussed by the authors is an important discipline of palaegeography, and it is developed on the foundation of traditional LPA and palaeoencoderography.

TL;DR: For more than a century, molar tooth structure (MTS) has been studied and several hypotheses concerning the origin of MTS have been developed as mentioned in this paper, such as seismic activity and biological activity.

TL;DR: In this paper, the distribution of the microbial mat-related structures (MRS) on siliciclastic sediments in the intertidal and supratidal zones was examined.

TL;DR: In this article, a review article by Wang et al. is aimed at illustrating that interpretations of ten ancient examples in China and one in the central Appalachians (USA) as deep-water deposits of internal waves and internal tides are unsustainable.

TL;DR: In this paper, a model of siliciclastic-carbonate sediment mixing, including both the depositional and diagenetic developments, is presented; it is aimed at generating a better overview of, and a deeper insight into, the physical and chemical mechanisms involved.

TL;DR: Based on seismic minimum amplitude slices, well logging data, test analytical data and so forth, detailed research on the evolution of the shallow water delta of the Neogene Lower Member of Minghuazhen Formation was conducted.

TL;DR: In this paper, the Siwalik Group depositd in Darjeeling-Jalpaiguri Districts, eastern India is investigated and a multi-modal palaeocurrent pattern is found to be multidimensional on the fans, virtually unimodal on the axial channel zone and again multidomain on the flood plain.

TL;DR: In this article, the lithofacies palaeogeography of the Late Permian Wujiaping Age in Middle and Upper Yangtze Region was studied based on petrography and the single factor analysis and multifactor comprehensive mapping method.

TL;DR: A continuous Permian-Triassic boundary (PTB) section has been found and studied for the first time in Xiushui, Jiangxi Province, South China.

TL;DR: Wang et al. as discussed by the authors proposed the most common 12 ichnoassemblages, in which six are found in fluvial sedimentary environments from the Upper Cretaceous of the Sichuan Basin of western China and Xixia Basin in western Henan Province.

TL;DR: In this paper, the authors proposed that peritidal cycles on an Early Triassic isolated carbonate platform in Guizhou, South China, were formed by hierarchical carbonate productivity variations.

TL;DR: In this article, the authors used clays as an indicator of the sediment source and prevailing climate and five suites (I-V) were identified throughout the borehole and significant changes in sediment sources are consistent with the evolution of regional sedimentary environments.

TL;DR: In this article, sediment lithology, fallout of 210 Pb and 137 Cs, and spheroidal carbonaceous particles (SCPs) for two short cores, YZE and CX38, obtained by gravity corer from the Yangtze River mouth offshore and adjacent continental shelf, to compare geochronological methods on the recent sediments of this area.

TL;DR: In this paper, a number of well-rounded mud balls, 2-20 cm in diameter, were observed after rainfall and a short flood in the otherwise dry Xiaohe (small river) valley of Guanling County, Guizhou Province, South China.

TL;DR: In this article, the authors take the evolution of Dalandzadgad and Solonker oceanic basins as examples and illustrate the viewpoint that there developed residual marine basins in former backarc/forearc regions after the disappearance of oceanic crust.

TL;DR: Zhang et al. as discussed by the authors suggested that upland subtropical evergreen broad-leaved forest dominated by Quercus/Lithocarpus was common around the Yuanmou Basin during the late Miocene, while a lowland deciduous broad-leaf forest dominated with Pterocarya was present on the river bank of the basin during the Late Miocene.

TL;DR: In this article, detailed zircon U-Pb dating and whole-rock geochemical analyses were carried out on the sedimentary rocks of the Paleogene Dainan Formation from Gaoyou Sag in the North Jiangsu Basin, East China.

TL;DR: In this article, the problems within delta models are discussed in depth, and especially the distinction characteristics for subfacies and microfacies of deltas are summarized on the basis of modern delta study.

TL;DR: Gao et al. as mentioned in this paper pointed out that Shanmugam has provided a critical assessment of our work and concluded that any interpretation of ancient strata as deposits of internal waves and internal tides is premature.

TL;DR: Wang et al. as mentioned in this paper divided the members 2 and 3 of the Lingshui Formation into two longterm base-level cycles and 10 mid-term baselevel cycles under the guidance of high-resolution sequence stratigraphy theory.

TL;DR: In this paper, the fine-medium sized crystalline dolomites are transformed from previous mud-sized crystalline diameters by recrystallization in penecontemporaneous period.

TL;DR: In this article, the authors focused on the faunal abundance, ecological patterns, and environmental interpretation of a Middle Triassic section in Central Nevada and collected twelve bulk samples from hand samples and thin-sections were used to aid in environmental interpretation.

TL;DR: The taxonomy of the subfamily Hecticoceratinae of Kutch was in a state of flux until recently as discussed by the authors, and it was not revised since Spath's (1927-1933) great contribution.
