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 ...

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.
