A high-resolution carbon-isotope record of the Turonian stage correlated to a siliciclastic basin fill: Implications for mid-Cretaceous sea-level change

Popis výsledku v původním jazyce

Nearshore siliciclastic strata in two separate sub-basins are correlated to a multi-stratigraphic dataset generated from research core (Bch-1) drilled in offshore marine sediments of the Bohemian Cretaceous Basin. A high-resolution ?13Corg record fromBch-1 is presented alongwithmajor- and minor-element proxies, TOC, carbonate content, terrestrial to marine palynomorph ratios, and detailed macro- and microfossil biostratigraphy. The 400 m thick Turonian through Lower Coniacian interval permits correlation to the highest-resolution C-isotope curves available: all carbon-isotope events demonstrated by ?13Ccarb studies in the British Chalk, NW Germany and other reference sections in Europe are recognized in the ?13Corg curve from Bch-1. A number of short-term, basin-wide regressions in the Bohemian Cretaceous Basin, most likely reflecting eustatic falls, show a recurrence interval of 100 kyr or less. This is an order ofmagnitude shorter than the timing of sea-level falls inferred from the
