Palynofacies distribution in a lacustrine basin

Geobios, 2005
Abstract The Miocene basin of La Cerdanya (Pyrenees, Catalonia, Spain) consist of lacustrine diatomites and fan-deltaic (palustrine) lutites with lignites. A multidisciplinary analysis of palynofacies, organic geochemistry, taphofacies of plant macroremains and sedimentology was carried out in order to characterise taphonomically this basin ...

Palynofacies changes and their reflection on preservation of peat accumulation stages in the Late Permian coal measures of the Bowen Basin, Australia: A new system for coal palynofacies characterisation

International Journal of Coal Geology, 2013
A high-resolution study (n = 66) was conducted on Late Permian coal measures of the Bowen Basin, Australia, to observe palynofacies changes during peat accumulation over time. Palynofacies were determined using polytopic vector analysis (PVA) to derive end members with variable compositions that reflected fine scale environmental changes, within and ...

Palynofacies and sequence stratigraphy of the Aptian–Albian of the Sergipe Basin, Brazil

Sedimentary Geology, 2006
Abstract In order to place information from palynofacies variations in a sequence stratigraphic context, palynofacies analyses for wells GTP-17-SE and GTP-24-SE from the Sergipe Basin, was integrated with sequence stratigraphy. Previous works assigned the succession to two second-order sequences, K50 and K60, the last being subdivided into systems ...

Object segmentation within microscope images of palynofacies

Computers & Geosciences, 2008
Identification of fossil material under a microscope is the basis of micropalentology. Our task is to locate and count the pieces of inertinite and vitrinite in images of sieve sampled rock. The classical watershed algorithm oversegments the objects because of their irregular shapes.
