Características morfológicas y sedimentológicas de las dunas eólicas de Sonabia (zona oriental de Cantabria, NO de España)

open access: yesEstudios Geologicos, 1991
Se estudian los campos eólicos de la playa de Sonabia (E de Cantabria, Golfo de Vizcaya), desde el punto de vista de su clasificación y caracterización morfológica y sedimentología (textura y contenido carbonatado bioclástico como parámetro indicador de ...

Renormalization group evolution of the CKM matrix [PDF]

open access: yes, 2003
We present here the most important ideas, equations and solutions for the running of all the quark Yukawa couplings and all the elements of the Cabibbo-Kobayashi-Maskawa matrix, in the approximation of one loop, and up to order $\lambda ^{4}$, where ...

Sedimentary biogeochemical provinces in the northern limit of the oxygen minimum zone from the northeastern Mexican Pacific

open access: yesSedimentology, EarlyView.
ABSTRACT Continental margins are reservoirs of materials of terrestrial and marine origin, and they play a crucial role in understanding the spatial and temporal variability of biogeochemical cycles. This, in turn, provides insights into the development and intensity of oxygen minimum zones (OMZs).

Environmental variables, habitat discontinuity and life history shaping the genetic structure of Pomatoschistus marmoratus [PDF]

open access: yes, 2014
Coastal lagoons are semi-isolated ecosystems exposed to wide fluctuations of environmental conditions and showing habitat fragmentation. These features may play an important role in separating species into different populations, even at small spatial

Quantitative analysis of channel characteristics of distributive fluvial systems

open access: yesSedimentology, EarlyView.
ABSTRACT Distributive fluvial systems (DFSs) are characterised by a radial distributive channel pattern in planform and dominate modern‐day sedimentary basins. Where aggradation occurs, such as in sedimentary basins, there is increased preservation potential, and therefore, DFSs are hypothesised to constitute a significant portion of the continental ...

CP and T Violation in Neutrino Oscillations

open access: yes, 2003
In this short lecture, we discuss some basic phenomenological aspects of CP and T violation in neutrino oscillation. Using CP/T trajectory diagrams in the bi-probability space, we try to sketch out some essential features of the interplay between the ...

A tale of two microbialites: Stromatolites and microbially induced sedimentary structures

open access: yesSedimentology, EarlyView.
ABSTRACT Microbialites are biosedimentary structures built by microbial mats. Five microbialite groups are distinguished: stromatolites, thrombolites, dendrolites, leiloites and microbially induced sedimentary structures (MISS). This contribution discusses the two most abundant microbialite groups in marine settings, stromatolites and MISS.
