The White Stone Band of the Kimmeridge Clay Formation, an integrated high resolution approach to understanding environmental change

, 2004
The Kimmeridge Clay is a Jurassic mudrock succession that shows Milankovitch Band climatic cyclicity. A key issue is to determine how the subtle changes that define this cyclicity result from climatic change.

Palaeogeographic Variability and Depositional Environments of the Upper Jurassic Carbonate Rocks of Velika Kapela Mt. (Gorski Kotar Area, Adriatic Carbonate Platform, Croatia) [PDF]

, 2002
Synsedimentary tectonics caused significant differentiation of sedimentary environments of the Adriatic Carbonate Platform during the Kimmeridgian. The most important changes have been recorded in W and central Croatia: along the NW part in present day W

Organic matter accumulation and preservation controls in a deep sea modern environment: an example from Namibian slope sediments.

, 2004
The Lüderitz upwelling cell is presently the most productive area of the Benguela current system and abundant organic matter (OM) accumulates on the adjacent slope sediments even at great water depth. OM from two cores taken on the slope and covering the

Organic facies variation in the late Kimmeridgian of the Boulonnais area (northernmost France) [PDF]

, 2001
Recent studies of the upper Kimmeridgian of the Boulonnais area (northernmost France) have provided a sequence-stratigraphical framework that is here used to help interpret variations in sedimentary organic matter (OM) content and composition in response

Palynofacies analysis – principles and application for paleoenvironmental studies: implications from Bulgaria

Review of the Bulgarian Geological Society, 2021
The use of palynofacies analysis has been steadily increasing during the last decades. This stems from both commercial interests (i.e., hydrocarbon exploration) and academic research of past environments and studies of the global climate changes that took place during the Phanerozoic.

Lacustrine organic fluxes and paleoclimatic variations during the last 15 ka : lac du Bouchet (Massif Central, France) [PDF]

, 1996
To assess the influence of climatic changes on organic lacustrine sedimentation, two cores recovered from the centre of the Lac du Bouchet were studied by petrographical (palynofacies) and geochemical methods.

Palynofacies analysis and depositional environment of the upper Triassic Kurra Chine Formation: integrated by samples from sarta and Tawke oil fields and outcrop samples from sirwan valley in the kurdistan region, northern Iraq

IOP Conference Series: Earth and Environment
Palynofacies (PF) analysis was conducted on 34 crushed samples of the Upper Triassic Kurra Chine Formation. These samples were collected from one outcrop sample and two production wells in northern Iraq.

The Carboniferous-Permian transition in Arunachal Pradesh, North East India: A palynological and palynofacies study

Earth History and Biodiversity
Palynological and palynofacies analyses were carried out from an outcrop of the Bichom Formation located in Arunachal Pradesh, North-East India. The age of the Bichom Formation at this locality is inferred based on palynological investigation and ...

Permian climate change recorded in palynomorph assemblages of Mozambique (Moatize Basin, eastern Tete Province) [PDF]

, 2017
Knowledge of Late Permian biodiversity patterns, following the end-Guadalupian crisis, is still in its infancy, since most recent studies have focused on the end-Permian biotic crisis.

Palynological and Organic-Petrographic Data on Very Low- and Low-grade Metamorphic Rocks in the Slavonian Mountains (Northern Croatia)

Geologia Croatica, 2010
The palynological data suggest a Late Silurian to ?Early Carboniferous sedimentation age for the weakly metamorphosed rocks from the Mts. Psunj, Papuk and Krndija (Slavonija, North Croatia).
