“…The Triassic rocks are separated from the overlying Eocene sediments by a Late Cretaceous to Eocene hiatus. From the Late Eocene to Early Miocene an approximately 700 mthick transgressive deposit of shallow marine limestone (Szépvölgy Limestone), pelagic marl (Buda Marl) and clay (Kiscell and Tard Clay Formations) was formed (Báldi 1983;Nagymarosy et al 1986). Post-volcanic fluids penetrated the Triassic-…”

“…Marine sedimentation was continuous from the Late Eocene to the Early Miocene. It began with the deposition of basal conglomerate beds, followed by shallow marine limestone (Szépvölgy Limestone), pelagic marl (Buda Marl), and clay (Kiscell and Tard Clay Formations) (Báldi 1983;Kázmér 1985;Nagymarosy et al 1986). The total thickness of the Eocene-Oligocene strata is about 700 m.…”

“…The Tard Clay Formation includes laminated and non-laminated shale and sandstone (Brukner-Wein et al, 1990). The degree of lamination varies considerably within the formation but is often the highest in its middle part, representing the nannozone NP23 (Nagymarosy, 1983), where dark grey siltstone alternates with white coccolith layers. These intervals are characterised by high TOC contents (max.…”

“…III.2) cannot be excluded. It is reasonable to assume that during the Eocene-Oligocene transition the continuous deepening of the Hungarian Palaeogene Basin (Nagymarosy et al, 1986) resulted in conditions favourable for organic matter enrichment. Within this context, it is important to note that Buda Marls in well W-9 contain a maximum of 2.7 wt% TOC (Fig.…”
