Extent and duration of marine anoxia during the Frasnian– Famennian (Late Devonian) mass extinction in Poland, Germany, Austria and France [PDF]

open access: yes, 2004
– The intensity and extent of anoxia during the two Kellwasser anoxic events has been investigated in a range of European localities using amultidisciplinary approach (pyrite framboid assay, gamma-ray spectrometry and sediment fabric analysis).

Stratigraphy of diagenesis: Limestone–dolomite cycles in a mid‐ramp setting, Miocene Arcadia Formation, South Florida, USA

open access: yesThe Depositional Record, EarlyView.
The data and interpretations of this study are used to test the proposal by Goldhammer et al. that a ‘stratigraphy of early diagenesis’ is operational in carbonate depositional systems. What this means is that distinct mineralogical and geochemical changes to rock and sediment occur associated with external controls, such as the rise and fall of sea ...

Birth, life and death of the Pannonian Lake [PDF]

open access: yes, 1990
The Miocene-Pliocene Pannonian Lake formed in an extensional basin system behind the compressional arc of the Carpathians. Its size and depth were comparable to those of the Caspian Sea.

«Prima facie»

open access: yesEUNOMÍA. Revista en Cultura de la Legalidad, 2022
El objetivo de este trabajo es identificar y caracterizar brevemente las maneras en que los juristas entienden el carácter prima facie de una norma. Para ello reconstruiré los dos sentidos que la literatura especializada usualmente le atribute: i) como una forma de presentar un problema de falta de información sobre el alcance de la norma (prima facie ...

Influence of environment and mineralogy on euendolithic microboring patterns

open access: yesThe Depositional Record, EarlyView.
Field experiments at Little Ambergris Cay reveal that euendolithic microorganisms preferentially bore carbonate substrates based on mineralogy, sea water saturation and trace metal content. Results highlight night‐time dissolution activity and mineralogical preferences, shedding light on the ecological and evolutionary drivers of bioerosion and their ...

Facies, development and interpretation of sedimentary environment of the uranium-bearing Brebovnica Member of the Val Gardena Formation in the Žirovski vrh area, W Slovenia

open access: yesGeologija, 2002
The Brebovnica Member, bearing considerable grades of uranium ore, is the most important member of the Val Gardena Formation. Rocks were subdivided according to grain size, sedimentary structures and composition to conglomerate, sandstone, mudstone and ...

Diagenetic processes controlled by volcanic detritus of the Lower‐Middle Permian Shanxi and Shihezi sandstone formations, North Ordos Basin, China

open access: yesThe Depositional Record, EarlyView.
Comparisons of Lower‐Middle Permian Shanxi and Lower Shihezi formations from the North Ordos Basin reveal that different types and percentages of volcanic detritus induced by active magmatic cycles can significantly change diagenetic evolution and favourable reservoirs.

Facies and paleoenvironmental reconstruction of Early–Middle Miocene deposits in the north-west of the Zagros Basin, Iran

open access: yesGeologica Carpathica, 2019
Facies analysis and paleoenvironmental reconstruction of the Burdigalian to Langhian Asmari Formation, outcropping in the Khorram Abad Anticline, in the north-west of the Zagros Basin allow us to interpret the carbonate ramp history during the Early ...
