Abstract

Summary

The Siciny-2 well is an ideal example to demonstrate the technique of chemostratigraphy. The sediment is described as monotonous mudstone and sandstone successions, while the well itself is drilled in the Fore-Sudetic Monocline, located in the south-west portion of the Polish Basin and is heavily affected by the Variscan orogeny, and then by latter inversion events. All these hurdles can prove problematic for traditional subsurface correlation techniques. Within this example the study well is sub-divided into four chemostratigraphic sequences and eighteen chemostratigraphic packages using elements associated with provenance, weathering and palaeoproductivity. Intergrated biostratigraphy, which recognises six biozones, highlights the occurrence of marine bands, and shows how the geochemical data can be used to highlight marine bands. Furthermore, from the geochemical characterisation of the Carboniferous and Permian a new top Carboniferous pick is identified.
