Spectral reflectance outcrop logging of Lower Devonian ramp carbonates, Barrandian area, Czech Republic; correlation with magnetic susceptibility and gamma-ray logs

Popis výsledku v původním jazyce

Spectral reflectance (SR) is a relatively novel technique, which is used as a proxy for organic carbon and siliciclastic input in carbonate sediments especially in core research. This paper summarizes results from high-resolution outcrop SR logging of aLower Devonian ramp slope carbonate section of the Barrandian area, Czech Republic. The SR data are correlated with parallel gamma-ray spectrometry and magnetic susceptibility logs with an aim to improve their cyclostratigraphic and event stratigraphic interpretation potential. Two transgressive-regressive cycles can be identified: an early to late Lochkovian cycle and a Pragian to early Emsian cycle. The cycles are identified with increasing and decreasing concentrations of Th and K. The maximum regressions in the early Lochkovian, earliest Pragian (the Basal Pragian Event) and the earliest Emsian intervals, which correlate with the Euramerican eustatic sea-level curve, are marked with peaks on the brightness (CIE L*) curve.
