The Oberhof trough is by far the largest of the main geologic parts of the Thuringian Forest. It consists of the uplifted part of the so-called ''Thuringian Forest Basin'' whose contents can be further subdivided into several formations. Their relative ages have not been fully resolved yet, partly because the Oberhof trough had been a [[rift]] zone with intense tectonics and continual changes of the internal relief and of the main areas of deposition.<ref name="VoigtTIF"/> The tectonic processes were accompanied by an intense [[felsite|felsitic]] volcanism which was the origin of many volcanic rock formations, predominantly rhyolites of [[Porphyry (geology)|porphyric]] structure with accompanying [[tuff]] deposits. These volcanic rocks alternate in sequence with the typical reddish molasse sediments (conglomerates, sandstones, siltstones, and claystones) of the Rotliegend.
