The Depositional Record, EarlyView.A classical peripheral foreland basin is bounded longitudinally by a pair of marginal ocean basins (DeCelles & Giles, 1996). The WTFB sediments transfer to adjacent marginal ocean basins. The western Taiwan foreland basin (WTFB) is regarded as a classical peripheral foreland basin, longitudinally bounded by the southern Okinawa Trough (SOT) to the ...

Freshwater Biology, Volume 68, Issue 1, Page 115-126, January 2023., 2023 Abstract Body metrics are considered as master traits that regulate physiological, behavioural and life history features of planktic cyanobacteria and microalgae. Although the distribution of their morphological traits reflects the various trade‐offs and strategies needed for survival in pelagic habitats, previous methods for quantifying phytoplankton ...

Endogenous versus Exogenous Origins of Crises [PDF]
in the monograph entitled ``Extreme Events in Nature and
Society,'' Series: The Frontiers Collection, S. Albeverio, V. Jentsch and H.
Kantz, eds. (Springer, Heidelberg, 2005), 2004 Are large biological extinctions such as the Cretaceous/Tertiary KT boundary due to a meteorite, extreme volcanic activity or self-organized critical extinction cascades? Are commercial successes due to a progressive reputation cascade or the result of a well orchestrated advertisement?

Morphometric Analysis of Dinosaur Tracks from Southwest Arkansas [PDF]
, 2013 Dinosaur trackways were discovered in Cretaceous De Queen Limestone strata in Howard County, Arkansas, in June 2011. Multiple trackways with variably sized tridactyl tracks were exposed in a commercial quarry, suggesting multiple theropod species or ...

Lacustrine and fan‐delta sediments in syn‐rift lake basins
The Depositional Record, EarlyView.A consistent model for the sequence framework and depositional pattern of asymmetric half‐grabens in syn‐rift lake basins bounded by active faults has been established, complementing existing models for marine rift successions. Syn‐rift lake basins are characterised by relatively small dimensions, steep slopes, poorly developed shoreline strata ...

Fossilization in Geopark Araripe studied through X-ray diffraction, scanning microscopy and thermogravimetric analysis [PDF]
arXiv, 2008 The Geopark Araripe, located in Northeastern Brazil, is the first UNESCO Natural Park in the South hemisphere and a world-famous fossil deposit of the Early Cretaceous period (approximately 120 million years). Fossilized fish fauna in Geopark Araripe is found inside of sedimentary rocks in three-dimensional forms. In the present study sedimentary rocks

Plant microfossil record of the terminal Cretaceous event in the western United States and Canada [PDF]
Plant microfossils, principally pollen grains and spores produced by land plants, provide an excellent record of the terminal Cretaceous event in nonmarine environments.

Soft-Shelled Turtles (Trionychidae) from the Cenomanian of Uzbekistan [PDF]
, 2014 Localities from the Cenomanian of Uzbekistan are the oldest in Middle Asia and Kazakhstan to preserve two broadly sympatric species of trionychid turtle. Material described here comes from multiple Cenomanian formations from the Itemir locality, and from

The Depositional Record, EarlyView.A limestone cave in the NW Dinarides exhibits an anomalous presence of montmorillonite clay, not commonly found in surrounding caves, posing questions about its origin and age. Analysis reveals a composition similar to weathered tephra from the Smrekovec Volcanic Complex, suggesting transport by north‐east winds.

A Geothermal Well Doublet for Research and Heat Supply of the TU Delft Campus [PDF]
arXiv, 2020 A geothermal well doublet, designed for two primary aims of research and commercial heat supply, is planned to be constructed on the campus of Delft University of Technology. The plans include a comprehensive research programme, including installation of a wide range of instruments alongside a comprehensive logging and coring programme and an extensive
