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

Journal 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 ...

Eocene–early Oligocene climate and vegetation change in southern China: Evidence from the Maoming Basin [PDF]

, 2017
Although the Eocene-Oligocene climate transition marks a critical point in the development of the ‘icehouse’ global climate of the present little is known about this important change in the terrestrial realm at low latitudes.

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

Acta 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.

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

, 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.

Reconstructing ancient vegetation, climate, depositional setting and ecology of the West Bokaro Coalfield, India: Insights from megafloristics and palynofacies

Geosystems and Geoenvironment
This study investigates the ancient vegetation, climate, depositional setting, and ecology of the West Bokaro Coalfield, with a focus on megafloral and palynofacies analyses from the Parej East Open Cast Project (OCP).

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

, 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

Moving forwards? Palynology and the human dimension [PDF]

, 2016
For the greater part of the last century, anthropogenic palynology has made a sustained contribution to archaeology and to Quaternary science in general, and pollen-analytical papers have appeared in Journal of Archaeological Science since its inception.
