Detecting sedimentary cycles using autocorrelation of grain size. [PDF]
Sci Rep, 2013 Detection of sedimentary cycles is difficult in fine-grained or homogenous sediments but is a prerequisite for the interpretation of depositional environments. Here we use a new autocorrelation analysis to detect cycles in a homogenous sediment core, E602, from the northern shelf of the South China Sea.

Unconventional Resources, 2023 Complex lithofacies of Lucaogou Formation in Jimusar Sag promote strong heterogeneity of oil distribution in fine grained sedimentary rocks. It is of great significance to define the formation mechanism of fine-grained sedimentary rocks for favorable ...

GeofluidsBase-level cycles serve as a crucial reference for the stratigraphic sedimentology. In lacustrine basins, high-frequency base-level changes contribute to significant diversity and complexity in sequences and sedimentary infilling.

Identification of Milankovitch Cycles and Their Sedimentary Responses in Fine-Grained Depositional Strata on the Southwestern Margin of the Songliao Basin [PDF]
Applied SciencesA series of fault depressions developed in the Kailu area on the southwestern margin of the Songliao Basin, where thick lacustrine fine-grained sedimentary rocks were widely deposited during the initial faulting stage in the Early Cretaceous.

Geophysical methods for the study of sedimentary cycles [PDF]
Petroleum Science, 2009 We present the wavelet depth-frequency analysis and variable-scale frequency cycle analysis methods to study sedimentary cycles. The spectrum analysis, variable-scale frequency cycle analysis, and wavelet depth-frequency analysis methods are mainly discussed to distinguish sedimentary cycles of different levels. The spectrum analysis method established

Eocene and Oligocene sedimentary cycles in New Zealand [PDF]
New Zealand Journal of Geology and Geophysics, 1967 Abstract Neritic deposits of Eocene and Oligocene age, partly underlain by coal measures, occur over large areas of south-west Auckland, west Nelson and north Westland, and north-east Otago (Waitaki). The well described deposits of south-west Auckland and Waitaki consist of sedimentary units bounded by unconformities and each containing distinctive ...

Microbial Community Dynamics and Biogeochemical Cycling in Microplastic-Contaminated Sediment [PDF]
NanomaterialsSediments are important repositories for microplastics (MPs) which exhibit higher microbial community richness and greater diversity than corresponding aqueous phases.

Detrital sedimentary content evolution during an orogenic cycle
, 2019 Les sédiments reflètent l'évolution des processus de surface résultant des interactions entre tectonique et climat. Cette thèse est focalisée sur le nord de l'Ibérie, qui enregistre les différentes étapes du cycle alpin. Elle a pour but, au travers d'une étude combinée thermochronométrique basse température, de retracer l'évolution du contenu ...

Australasian Cenozoic Sedimentary Cycles, Global Sea Level Changes and the Deep Sea Sedimentary Records [PDF]
, 1981 A global sea level history determined by Vail et al. (1977) consists of 23 sea level cycles between the base of the Cenozoic and the Pliocene-Pleistocene boundary (65 Ma to 1.8 Ma). The authors have examined the relationship between this global sea level history and the New Zealand and Australian continental margin shallow marine sedimentary record and
