Cyclostratigraphy of Shallow-Marine Carbonates – Limitations and Opportunities [PDF]

, 2018
The sedimentary record of ancient shallow-marine carbonate platforms commonly displays a stacking of different facies, which reflects repetitive changes of depositional environments through time. These changes can be induced by external factors such as cyclical changes in climate and/or sea level, but also by internal factors such as lateral migration ...

Astronomical cycle framework and carbonate platform evolution of Permian Longtan Formation–Triassic Feixianguan Formation in Sichuan Basin, SW China

Petroleum Exploration and Development
Based on data from cores, well logs, seismic profiles, and carbon isotopic compositions, this study constrains the chronostratigraphic framework using carbon isotopic excursion events and applies cyclostratigraphic methods to establish a high-resolution ...

Seismic Cyclostratigraphy: Significance Testing for Orbital Cyclicity in Seismic Reflection Data [PDF]

, 2023
Quasi-periodic orbital cycles may be expressed as peaks in the power spectrum of seismic images of sedimentary deposits, if the bandwidth includes the relevant spatial frequencies and if cyclicity is preserved in the impedance.

The Sequence Stratigraphic Division and Geological Significance of Lower-Middle Ordovician Carbonate Rocks in Fuman Area, Tarim Basin, China

Geosciences
Oil and gas exploration conducted in the main fault zone of the Fuman Oilfield has yielded large-scale and high-production results. Against this background, the non-fault zone has emerged as a new domain for oil exploration endeavors.
