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).

Paleolimnology and Natural Versus Anthropogenic Influx During the Late Holocene from Vembanad Wetland, Ramsar Site, Kerala, India

Quaternary
A multi-proxy study of diatoms, palynofacies, and grain size was conducted on a 100 cm core from Arookutty, Vembanad wetland, Kerala, India, to reconstruct paleolimnological changes during the late Holocene, with a focus on natural versus anthropogenic ...

Mechanism of Late Campanian–Early Maastrichtian oil shale deposition and its sequence stratigraphy implications inferred from the palynological and geochemical analysis

Egyptian Journal of Petroleum, 2014
Understanding the organic rich sediment deposition mechanism is vital for the purposes of their exploration. This should reconsider the sequence stratigraphic framework and its associated paleoenvironmental setting.

Past environments of Sardinian archaeological sites (Italy, West Mediterranean Sea), based on palynofacies characterization

Acta Palaeobotanica, 2018
A study method based on characterization of palynofacies (organic matter, palynomorphs) preserved in sediments was applied to obtain information about past environments of Sardinian sites. Organic matter (OM) was classified in ten categories according to
