Lacustrine couplet-lamination: evidence for Late Pennsylvanian seasonality in central equatorial Pangaea (Stephanian B, Slaný Formation, central and western Bohemian basins)

Popis výsledku v původním jazyce

Lacustrine mudstones of the Mšec Member were acquired from two shallow boreholes 80 km apart and were analysed for mineral composition and dispersed organic matter, lamination structure, and lamination periodicity to gather more detailed information on the palaeoenvironmental change with a near annual resolution. The structure and development of the lamination is discussed in the context of previous detailed geochemical analysis of the lacustrine mudstones. The organic?detritic couplet lamination is composed of alternating dark (rich in algal remnants and clay) and light (rich in siliciclastics, carbonates, and terrestrial floral remnants) laminae suggesting their formation in response to seasonal changes in rainfall similarly as in some modern tropical lakes. Couplet thickness distribution shows statistically significant periodicities resembling multiannual to multidecadal scales observed in recent sediment archives.
