One problem frequently confronted in sequence studies is determining which of these worldwide events is represented in the section of interest. Correlating a local section to the global cycles requires accurate and precise biostratigraphy, either through zonal age determination or by providing the necessary age constraints on magnetostratigraphic or isotope stratigraphic interpretations. When based on reliable age control, correlation with the succession of global processes can be a valuable predictive stratigraphic tool for understanding the temporal and areal distribution of reservoir, source, and seal rocks.

Biostratigraphic correlation between sections separated by a fault zone or other major geologic feature is frequently much more reliable than seismic reflectors or well log picks. Correlation across growth faults, where stratal thickness and character can vary greatly from the high to the low side, is a notable example.
