Chemostratigraphy of Neoproterozoic carbonates: implications for 'blind dating' [PDF]

, 2001
The delta C-13(carb) and Sr-87/Sr-86 secular variations in Neoproteozoic seawater have been used for the purpose of 'isotope stratigraphy' but there are a number of problems that can preclude its routine use.

The Severe 2013–14 Winter Storms in the Historical Evolution of Cantabrian (Northern Spain) Beach-Dune Systems

Geosciences, 2018
The 2013⁻14 winter storms were the most energetic storms in the European Atlantic on record since at least 1948. They caused intense erosive processes along the coast, similar to those described previously in places such as the United Kingdom and ...

Late Tremadocian (Early Ordovician) reefs on the Yangtze Platform, South China, and their geobiological implications: a synthesis

Journal of Palaeogeography, 2021
This study provides an overview and discussion of controls on the distribution of organic reefs during the Early Ordovican Period, in the Yangtze Platform, a region of epicontinental sedimentary rocks in South China.

Cenozoic evolution of the eastern Black Sea: a test of depth-dependent stretching models [PDF]

, 2008
Subsidence analysis of the eastern Black Sea basin suggests that the stratigraphy of this deep, extensional basin can be explained by a predominantly pure-shear stretching history.

Late Maastrichtian carbon isotope stratigraphy and cyclostratigraphy of the Newfoundland Margin (Site U1403, IODP Expedition 342) [PDF]

, 2018
Earth’s climate during the Maastrichtian (latest Cretaceous) was punctuated by brief warming and cooling episodes, accompanied by perturbations of the global carbon cycle.

Sequence Stratigraphy towards its standardization—an important scientific scheme [PDF]

E3S Web of Conferences, 2019
In the Post-Exxon Era of sequence stratigraphy, various sequence models for the complex stratigraphic records with their response mechanisms are developed. All the models with strong pertinence are endowed, which lead to misapprehension in the conceptual

A new method to evaluate the effects of mechanical heterogeneity on fault architecture in sedimentary sequences

Natural Gas Industry B, 2023
Geologists have long realized the important control of mechanical stratigraphy on fault nucleation, fault linkage and fault compartmentalization. However, uncertainties still exist concerning the mechanical heterogeneity of the stratigraphy because of ...
