Far-field correlation of palaeokarstic surfaces in Mississippian successions using high-frequency foraminiferal diversity trends

The degree to which emergent surfaces are correlated in late Asbian carbonate successions Britain and Ireland is assessed by the integration of detailed biostratigraphy diversity trends foraminifers. Data related Trowbarrow Quarry section northern England, provides a reference for upper because its rich assemblages high sampling density. Diversity shown be non-random, possess cyclic behaviour, can quantitatively between sections. allow stratigraphic segmentation into 13 intervals foraminiferal trends, sub-divide coarser-resolution biozones sub-biozones. Similar recognised sections hundreds kilometres away from Trowbarrow, South Wales, southeastern western Ireland, facilitating more precise correlation strata. These highlight coeval nature rhythms these regions, thus, establishing stratigraphy. This new assessment also enables better discrimination ‘missing beats’ large hiatuses successions. establishment this rhythmic stratigraphy permits recognition occurrence some biostratigraphical markers, enabling amendment biostratigraphic mismatches.
