It is middle Tournaisian in age (lowerPericyclus Stage, lower cd II of the German Culm zonation) and is an equivalent of the Liegende Alaunschiefer. The sequence is composed predominantly of minor turbiditic fining-upward cycles. Cycles start with massive calciturbidite beds. They are composed of fine-grained intraclastic-bioclastic grainstone/packstone, more or less ooid-bearing in the top of the formation, and/or radiolarian-rich packstone. Cycles continue with platy, dense limestones consisting of radiolarian-rich wackestone/packstone and microlithoclastic-microbioclastic wackestone/packstone. Different types of shales finish the fining-upward development. Minor cycles can be grouped into several 4th order cycles, composing a single 3rd order cycle. Towards the top, abundance of resedimented platform components, like ooids, calcareous smaller foraminifers, echinoderms, brachiopods, bryozoans and critical conodont genera, increases. Simultaneously, the thickness of the minor cycles decreases. This indicates a transgressive phase, characterized by increasing over-production of carbonate on platform realms and a correlated increase in the frequency of resedimentation events in the basin. The transgression corresponds to the well-documented global eustatic transgression of the Lowercrenulata andisosticha-uppercrenulata Zone of the conodont chronology. Thus, the Gladenbach Formation is interpreted as a transgressive systems tract/highstand systems tract. The Liegende Alaunschiefer is the time-equivalent, starved basin facies. Predominating hemipelagic calciturbidites of the lower Gladenbach Formation derive from the deeper shelf slope or from an intrabasinal swell, which might constitute a flexural bulge in front of the shelf slope. Turbidite sediments from the upper part of the formation derive from shelf-edge sands and the upper shelf slope. The source might be related to the ancient Devonian reef complex of Langenaubach-Breitscheid in the southwest.
