Increase Stratigraphic 
Resolution
VAKAROS, GABOR, A., VITOR ABREU, and PETER R. VAIL
The establishment of an age model for sedimentary sections is a crucial task
for stratigraphers. Current methods aiming to improve resolution and
stratigraphic correlation are based on the integration of all available age
data, such as biostratigraphy, chemostratigraphy, magnetostratigraphy and
cyclostratigraphy, also known as high resolution stratigraphy. We propose a
method to improve stratigraphic correlation and age resolution in sedimentary
sections through the integrate analysis of all methodologies described above
within a sequence stratigraphic framework.
During the interpretation process, relative chronostratigraphy derived from
detailed sequence-stratigraphy of seismic sections and well-logs is compared
with all available age data. Iterative interpretation develops a
chronostratigraphy which recalibrates the data sets. The results can
dramatically increase the stratigraphic resolution from millions of years to
hundreds of thousands of years. This method develops a more precise
chronostratigraphy and can also increase the stratigraphic resolution
of basins
where traditional methods are difficult to apply (e.g., lacustrine and brackish
basins).
Based on sequence stratigraphic analysis of 2D reflection seismic profiles and well-logs, the method was successfully tested in the Pannonian Basin, Hungary and in the South Atlantic region within a sedimentary succession from middle Eocene through Pliocene.
