Allogenic and autogenic processes combined in the formation of shallow-water carbonate sequences (Middle Berriasian, Swiss and French Jura Mountains) [PDF]

open access: yes, 2018
Sediment production and accumulation on shallow carbonate platforms are controlled by allogenic, externally controlled processes (such as sea level, climate, and/or platform-wide subsidence patterns) as well as by autogenic factors that are inherent to ...

Early Tithonian Saturnalidae (Radiolaria) from the Solnhofen area (Southern Franconian Alb, southern Germany) [PDF]

open access: yes, 2018
In order to complete the study of the very rich early Tithonian (Hybonoticeras hybonotum Zone) radiolarian fauna from the Mühlheim Member of the Mörnsheim Formation outcropping in the Solnhofen area, the taxa of the family Saturnalidae are described ...

New nephropid and glypheid lobsters from the Mesozoic of Japan

open access: yesRevista Mexicana de Ciencias Geológicas, 2018
A new nephropid lobster, Hoploparia kamimurai new species is described from the Lower Cretaceous Ishido Formation (Barremian), Gunma Prefecture, central Japan. Two species of glypheid lobsters, Glyphea yoshiakii new species and Glyphea sp. were obtained

Bazhenov horizon of Siberia (Tithonian – Lower Berriasian): tectonic and hydrodynamic conditions of sedimentation

open access: yesGeoresursy, 2019
The new model of the sedimentation of the Bazhenov Formation, on which black shale accumulated on relative elevation – a shallow-marine hilly plateau, agrees well with the results of a general paleogeographic analysis of the Bazhenov horizon of Siberia ...

DEEP WATER AGGLUTINATED FORAMINIFERA FROM THE JURASSIC/CRETACEOUS BOUNDARY AND PALEOENVIRONMENTAL SETTINGS OF THE MAIOLICA TYPE FACIES FROM THE CZORSTYN RIDGE (PIENINY KLIPPEN BELT, WESTERN CARPATHIANS)

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2017
Deep-water carbonates deposited on the Czorstyn elevated ridge of the Pieniny Klippen Belt paleogeographic domain record changes in agglutinated foraminifera morphogroups through the J/K boundary interval at the Erdútsky kostol section.

Сonditions of sedimentation and paleogeographic zoning of the Bazhenov horizon (Tithon-Lower Berrias) in West Siberia

open access: yesGeoresursy, 2017
In the global Upper Jurassic-Neocomian (Oxford-Valanginian) black-shale interval, the Bazhenov Formation occupies only the Tithonian – Lower Berriasian. The main regional reasons for this localization were the tectonic regime, the morphology of the basin’

LATE BERRIASIAN–EARLY VALANGINIAN EVOLUTION AND DROWNING OF THE GETIC CARBONATE PLATFORM (SE SERBIA)

open access: yesRivista Italiana di Paleontologia e Stratigrafia
 The Early Cretaceous was a time of significant development of carbonate platforms on the margins of the Tethys Ocean, including the Getic Carbonate Platform, in the northern peri-Tethys realm, cropping out in the Southern Carpathians (Romania) and ...
