Recent Sediments of Makirina Cove (Northern Dalmatia, Croatia): Their Origin Viewed Through a Multidisciplinary Approach [PDF]

open access: yes, 2005
Makirina Cove was formed by the Holocene sea-level rise which caused a marine ingression into the depression formed within Albian–Cenomanian dolomites at approximately 4.5 ka B.P.

Orbital frequencies in the carbonate sedimentary record: distorted by diagenesis? [PDF]

open access: yes, 2004
The most important archive of Earth’s climate change through geologic history is the sedimentary rock record. Rhythmic sedimentary alternations are usually interpreted as a consequence of periodic variations in the orbital parameters of the Earth.

Palynofacies analysis of Naokelekan formation, Northern Iraq

open access: yes, 2019
Palynofacies analysis of 38 rock samples of the Late Oxfordian-Early Kimmeridgian Naokelekan Formation from two exploratory wells and two outcrops in northern Iraq was performed. All samples taken from outcrops in Duhok and Sulaymaniyah provinces and well Bj-1 in northern Iraq were classified as palynofacies Type I (PF-1), which comprises mainly ...

A latest Cretaceous to earliest Paleogene dinoflagellate cyst zonation of Antarctica, and implications for phytoprovincialism in the high southern latitudes [PDF]

open access: yes, 2012
The thickest uppermost Cretaceous to lowermost Paleogene (Maastrichtian to Danian) sedimentary succession in the world is exposed on southern Seymour Island (65° South) in the James Ross Basin, Antarctic Peninsula.

Palaeodepositional consequences for hydrocarbon generation using geochemistry and palynology: example from Auranga coalfield in India

open access: yesJournal of Petroleum Exploration and Production Technology
Understanding the depositional environment is essential for evaluating hydrocarbon generation potential. This study examines the Lower Permian Barakar Formation in the Auranga Basin, part of the Damodar Valley within the Gondwana succession, by ...

Annual fossil organic carbon delivery due to mechanical and chemical weathering of marly badlands areas [PDF]

open access: yes, 2012
International audienceA key issue in the study of the carbon cycle is constraining the stocks and fluxes in and between C-reservoirs. Among these, the role and importance of fossil organic carbon (FOC) release by weathering of outcropping sedimentary ...

Palynofacies patterns of the Highveld coal deposits (Karoo Basin, South Africa): Clues to reconstruction of palaeoenvironment and palaeoclimate

open access: yesActa Palaeobotanica, 2016
The early Permian represents a crucial period of climate change in Gondwana. This climate signature is captured in the palynological record that represents the floral assemblage of the region. Palynofacies analysis of the No.

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

open access: yes, 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.

Holocene land-use evolution and associated soil erosion in the French Prealps inferred from Lake Paladru sediments and archaeological evidences [PDF]

open access: yes, 2013
International audienceA source-to-sink multi-proxy approach has been performed within Lake Paladru (492 m a.s.l., French Prealps) catchment and a six-meter long sediment sequence retrieved from the central lacustrine basin. The combination of minerogenic
