A shallow-water oxygen minimum zone in an oligotrophic Tonian basin [PDF]

open access: yesNature Communications
The Tonian Period (1000–720 Ma) bore witness to the transition from a prokaryote-dominated marine ecosystem to one characterized by the proliferation of eukaryotes.

Seismogenic potential and tsunami threat of the strike-slip Carboneras fault in the western Mediterranean from physics-based earthquake simulations [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2023
Strike-slip fault ruptures have a limited capacity to generate vertical deformation, and for this reason they are usually dismissed as potential destructive tsunami sources.

Strontium Isotope Stratigraphy

open access: yes, 2010
Abstract The 87Sr/86Sr value of Sr dissolved in the world’s oceans has varied through time in a known way. When minerals, such as biogenic calcite, precipitate from seawater, they incorporate Sr from seawater and capture the 87Sr/86Sr value for marine-Sr at the time of precipitation.

Biostratigraphy of large benthic foraminifera from the lower part of the Shahbazan Formation: revision of the age of the carbonate succession from the Tange Lilam section (Chenareh Anticline, Lorestan Basin) [PDF]

open access: yesJournal of Stratigraphy and Sedimentology Researches, 2022
In this study, the lower part of carbonate successions from the Shahbazan Formation in the Chenareh anticline of the Zagros sedimentary basin (SW of Iran) based on Large Benthic Foraminifera (LBF) was investigated.

The Origin and 3D Architecture of a Km-Scale Deep-Water Scour-Fill: Example From the Skoorsteenberg Fm, Karoo Basin, South Africa

open access: yesFrontiers in Earth Science, 2021
Scours, and scour fields, are common features on the modern seafloor of deep-marine systems, particularly downstream of submarine channels, and in channel-lobe-transition-zones.

High-resolution carbon isotope stratigraphy of the Lower and Middle Ordovician succession of the Yangtze Platform, China [PDF]

open access: yesEstonian Journal of Earth Sciences, 2023
Variation in the relative abundance of the stable carbon isotopes has been widely used to correlate Ordovician marine successions over the past two decades.

Darriwilian Saucrorthis Fauna: implications for the Great Ordovician Biodiversification Event (GOBE) [PDF]

open access: yesEstonian Journal of Earth Sciences, 2014
The Saucrorthis Fauna is a brachiopod-dominated shelly fauna developed in relatively deeper-water benthic regimes of a few peri-Gondwana terranes (e.g.

The Llandovery (Silurian) conodont species diversity on the Upper Yangtze Platform, South China [PDF]

open access: yesEstonian Journal of Earth Sciences, 2014
Conodonts are one of the stratigraphically most important fossil groups in the Silurian Period. We examine the regional diversity dynamics of the Llandovery condonts on the Upper Yangtze Platform.

Stratigraphy and sedimentology of distal-alluvial and lacustrine deposits of the western-central Ebro Basin (NE Iberia) reflecting the onset of the middle Miocene Climatic Optimum

open access: yesGeologica Acta, 2020
Stratigraphic and sedimentological study of distal alluvial and lacustrine deposits in the Plana de la Negra-Sancho Abarca area (western-central Ebro Basin, NE Iberia) within the early and middle Miocene allows five main lithofacies to be characterized ...
