Description and information about KEROGENIA

As most palynologists know, palynofacies analysis or kerogen classification is a powerful tool.

In contrast to stratigraphic palynology, which exclusively bases on palynomorphs (pollen, spores, dinoflagellates and acritarchs), palynofacies regards the complete organic residue. This covers further terrestrial components (plant debris, amorphous organic matter) and other components of marine or aquatic origin (algae, zoomorphs). Palynofacies analysis enhances interpretation of microfacies and can lead to a better understanding of the paleoenvironment, or it allows to evaluate the source rock potential.

Palynofacies counting means, that at least 300 , 500 particles ore more are classified and counted.

The conventional way is manually recording the counts on paper sheets. This is, at first glance, uncomplicated, but it will need to digitalize the data set for further interpretation. The digitalization implies additional time effort.

The second way is to use digital counting. This can be done with special biostratigraphic software regarding the different kerogen particles (e.g. dinocysts, sporomorphs or phytoclasts) as species. But generally, biostratigraphic software is designed for the special needs of chronostratigraphy and not for palynofacies analysis.

I decided to use Microsoft Excel® for palynofacies counting and some years ago, I developed a simple counting sheet, basing on the Visual Basic capability of Excel®. The advantage of Excel® is, that it is a component of the standard Microsoft Office® package and wide distributed on PC.
Over time, I improved and extended the functionality of the palynofacies counting sheet.
I added size classes for phytoclasts and developed a code which allows to display ternary APP (amorphous organic matter – pollen – palynomorphs) and SMP (spores – microplankton – pollen) diagrams.
All counting data is stored in the format first column sample depth, successive columns particle designation. This easily allows to use the data in external software, e.g STRATABugs® or WellCAD®.
