Increasing resolution in exploration biostratigraphy-Part i

Abstract

Crossplots with Ranking & Scaling (RASC) and Constrained Optimization (CONOP) zonal sequences increase stratigraphic resolution and correlation potential of biozonations. The crossplots reveal which events do and which do not deviate their stratigraphic position from well to well, and how well they track their average stratigraphic level. The methodology solves the problem that conventional fossil zonations do not rank taxa according to the degree of diachroneity of range endpoints in a correlation scheme. Part 1 of this study applies the crossplots method to a North Sea biostratigraphic data, and part 2 to a proprietary dataset from the Gulf of Mexico. © 2008 Springer-Verlag Berlin Heidelberg.
