Petroleum geology of the Upper Jurassic – Lower Cretaceous of East and North-East Greenland: Blokelv-1 borehole, Jameson Land Basin: Late Jurassic evolution of the Jameson Land Basin, East Greenland – implications of the Blokelv-1 borehole [PDF]

Geological Survey of Denmark and Greenland Bulletin, 2018
Data from the recently drilled, fully cored Blokelv-1 borehole and previous cored boreholes in the Upper Jurassic of Jameson Land, central East Greenland, are integrated with published field studies to address the depositional evolution of the Jameson ...

Environmental distribution of Bathonian (Middle Jurassic) neoselachians in southern England [PDF]

, 2004
Within the Bathonian (Middle Jurassic) a wide range of depositional environments were present across Britain. Within this dominantly carbonate shelf setting, there is a general palaeoenvironmental transition from open marine shelf in the south of England,

Environmental controls on the distribution of neoselachian sharks and rays within the British Bathonian (Middle Jurassic). [PDF]

, 2003
Extensive sampling from a range of facies within the Bathonian (Middle Jurassic) of southern England has allowed the palaeoenvironmental distribution of a number of taxa of neoselachian sharks and rays to be assessed.

Ostracod Biostratigraphy of the Kimmeridgian in Northern and Western Europe

Danmarks Geologiske Undersøgelse II. Række, 1970
The chronostratigraphical type profile of the Kimmeridgian of Dorset is subdivided biostratigraphically into five ostracod zones. Six other areas in Northern and Western Europe with Kimmeridgian ostracods are examined. The species are listed, counted, and examined in relation to the zones of the type Kimmeridgian.In the Lower Kimmeridgian the ostracod ...

DOCUMENTATION AND SIGNIFICANCE OF TECTONIC EVENTS IN THE NORTHERN TABAS BLOCK (EAST-CENTRAL IRAN) DURING THE MIDDLE AND LATE JURASSIC

Rivista Italiana di Paleontologia e Stratigrafia, 2004
Apart from global sea-level fluctuations, the sedimentary pattern of the northern Tabas Block during the Middle and Late Jurassic was mainly governed by tectonic events of varying intensity and areal extent.

Geology and Jurassic paleogeography of the Mt. Primo-Mt. Castel Santa Maria ridge and neighbouring areas (Northern Apennines, Italy) [PDF]

, 2014
This paper presents the results of a geological mapping project across the Mt. Primo ridge and neighbouring areas (Umbria-Marche Domain – Northern Apennines), where a thick Meso-Cenozoic carbonate succession is exposed.

CALCAREOUS NANNOFOSSIL BIOSTRATIGRAPHY OF UPPER CALLOVIAN-LOWER BERRIASIAN SUCCESSIONS FROM THE SOUTHERN ALPS, NORTH ITALY

Rivista Italiana di Paleontologia e Stratigrafia, 2010
Calcareous nannofossil biostratigraphy was investigated in uppermost Callovian-lower Berriasian sections from Southern Alps, previously detected through magnetostratigraphy, in order to achieve an integrated stratigraphic framework valid at low latitudes.

Oxfordian and Kimmeridgian "Aspidoceras" in the Mediterranean. A methodological approach

Estudios Geológicos, 1987
En el presente trabajo se lleva a cabo un análisis contrastador de la Hipótesis Nula establecida como base metodológica para la investigación evolutiva de los"Aspidoceras" mediterráneos (Checa & Olóriz, 1985). Esta contrastación se lleva a cabo integrando nuevos datos y forma parte de un programa de investigación cuidadosamente planificado.

Variability of continental depositional systems during lowstand sedimentation: an example from the Kimmeridgian of the Neuquen Basin, Argentina

Latin American Journal of Sedimentology and Basin Analysis, 2021
Several second order lowstand wedges are recognized in the Jurassic-Early Cretaceous sedimentary record of the backarc Neuquén Basin (central-west Argentina).

Plant remains from the Middle–Late Jurassic Daohugou site of the Yanliao Biota in Inner Mongolia, China

Acta Palaeobotanica, 2017
A late Middle–early Late Jurassic fossil plant assemblage recently excavated from two Callovian– Oxfordian sites in the vicinity of the Daohugou fossil locality in eastern Inner Mongolia, China, was analysed in detail.
