Uncertainty quantification and reduction in the characterization of subsurface stratigraphy using limited geotechnical investigation data

Underground Space (China), 2020
Subsurface stratigraphy is critical to the design, construction, and subsequent performance of geotechnical structures. However, in practice it is impossible to identify the stratigraphy of a subsurface geological domain with absolute certainty, due to ...

Revisiting early angiosperm pollination: a reassessment of Angimordella beetle and co-occurring thrips from mid-Cretaceous amber. [PDF]

BMC Biol
Background The Cretaceous rise of angiosperms profoundly reshaped terrestrial ecosystems, yet direct fossil evidence of early insect–angiosperm interactions remains scarce.

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

Natural 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.

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

Frontiers 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.

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

Geologica 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 ...

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

Estonian 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]

Estonian 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.

Stable isotope stratigraphy of the early Quaternary of borehole Noordwijk, southern North Sea [PDF]

, 2015
Between 2.58Ma and 2.4Ma, most of the present onshore sector of the Netherlands was an epicontinental sea. Previous studies suggest the occurrence of multiple cold and warm phases in shallow marine successions of the Maassluis Formation in conjunction ...
