"Spectral reflectance (SR) is used as a proxy for organic carbon and siliciclastic input in carbonate sediments.This study summarizes results from high-resolution outcrop SR logging of a Lower Devonian distal ramp carbonate section of the Barrandian area, Czech Republic.The SR data were correlated with parallel petrophysical and geochemical data with an aim to improving their cyclostratigraphic and event stratigraphic interpretation potential and the gaps SR data can fill. Transgressive\u2013regressive trends, indicated by facies stacking patterns, CaCO3 data and spectral gamma-ray (GRS) logs, are well correlated in the regional context and point to third-order eustatic sea-level fluctuations.The SR data, backed up by GRS, MS and CaCO3 data indicate that the red colour in the Pragian hemipelagic limestones originated from early diagenetic hematite precipitation under the conditions of an oxygenated ocean floor and deep-sea bottom oxygenation may have been in operation during Devonian." . . . .
