Poseidon's Sanctuary at Samikon—The Discovery of an Ancient Temple Through an Integrated Geophysical and Geoarchaeological Survey Approach for Lagoonal and Swampy Environments

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Below the classical fortress of Samikon at the coast of the western Peloponnese, ancient writer Strabo mentioned a sanctuary of Poseidon which served as the centre of the religious association of the Triphylian cities. In this paper, we describe the discovery and investigation of a building structure by means of geophysical and ...

A revision of the Lower Cretaceous foraminiferal genus Falsogaudryinella from northwest Europe and Romania, and its relationship to Uvigerinammina

open access: yes, 1995
We emend the definition of the foraminiferal genus Falsogaudryinella Bartenstein, 1977 based on observations of the type species, F. tealbyensis from the Barremian Lower Tealby Clay of Lincolnshire, U.K.

Loss, persistence and reversal of phenotypic traits

open access: yesBiological Reviews, EarlyView.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

Clathrate hydrate crystallization

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Clathrate hydrate crystallization has been an area of interest to chemical engineers from the point of view of crystal structure, thermophysical properties, phase equilibria, kinetics, industrial applications, and environmental (climate change) implications.

Taphonomy and paleoecology of lower cretaceous oyster mass occurrences from west-central Argentina and evolutionary paleoecology of gregariousness in oysters [PDF]

open access: yes, 2018
Lower Cretaceous (lower Hauterivian) oyster mass occurrences (OMOs) dominated by the gryphaeid small oyster Ceratostreon from the Neuquen Basin (west-central Argentina) are analyzed in terms of taphonomy and paleoecology in order to characterize their ...

Slip versus dilation tendency parameter space as a tool for prospecting structurally controlled geothermal systems in greenfield: insights from the greater Ruhr region

open access: yesDeep Underground Science and Engineering, EarlyView.
This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating

Provenance and geochemistry of exotic clasts in conglomerates of the Oligocene Torehina Formation, Coromandel Peninsula, New Zealand

open access: yes, 2003
Non-marine pebble to cobble conglomerates of the lower Torehina Formation (Oligocene) crop out along western Coromandel Peninsula and overlie, with strong angular discordance, continental-margin metasedimentary rocks (Manaia Hill Group) of Mesozoic (Late

Semi‐analytical solution for the stability of deep vertical shaft considering time‐dependent rock‐structure interaction

open access: yesDeep Underground Science and Engineering, EarlyView.
A novel cavity contraction solution and multilayer shaft wall model were developed to analyze deep shaft stability, considering rock viscosity, support structures, and water pressure, with successful validation through a Hulusu Coal Mine case study.
