A multi-dimensional dataset of Ordovician to Silurian graptolite specimens for virtual examination, global correlation, and shale gas exploration [PDF]

Earth System Science Data, 2023
Multi-elemental and multi-dimensional data are more and more important in the development of data-driven research, as is the case in modern paleontology, in which, in an examination by experts, or some day artificial intelligence, every fossil specimen ...

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 ...

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

Stratigraphy of the Anthropocene

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2011
The Anthropocene, an informal term used to signal the impact of collective human activity on biological, physical and chemical processes on the Earth system, is assessed using stratigraphic criteria. It is complex in time, space and process, and may be considered in terms of the scale, relative timing, duration and novelty of its various phenomena. The

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 ...

Hunger sweetens the beans: evidence of opportunistic feeding behaviour of the little owl (Athene noctua, Scopoli 1769) from Peloponnese, Greece

Raptor Journal, 2022
The little owl (Athene noctua) is a common raptor in Mediterranean habitats. To acquire more information on its diet, this study identified cranial and post-cranial skeletal material from 70 owl pellets collected during the 2016 and 2017 breeding seasons.

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.

PALEONTOLOGY AND PALEOGEOGRAPHY OF THE TETHYAN EARLY PALEOGENE ROTALIID BENTHIC FORAMINIFERAL PAKISTANIAN GENUS ORNATANOMALINA AND OTHER RELATED GENERA [PDF]

Earth Sciences Pakistan, 2021
Six Early Paleogene small Rotaliid benthic foraminiferal species of the genus Ornatanomalina Haque are common in Pakistan and some of them are recorded from some localities in the Southern Tethys (Iraq, Qatar, United Arab Emirates, Nigeria), as well as ...
