The average total organic carbon (TOC) content in the Menilite Formation is 4-8 wt%; the maximum measured is 26 wt%. Organic matter (OM) is oil-prone Type II kerogen derived mainly from algae and cyanobacteria which was deposited under euxinic conditions. The thermal maturity of the Menilite shales varies significantly within the Outer Carpathians, both vertically in relation to burial depth and laterally in different tectonic units, and increases from external to internal parts of the orogenic belt. Maturity in general ranges from immature to different phases of the "oil window" and up to the "gas window". 3 Journal of Petroleum Geology ARTICULO ddc 192376 192376 0 0 0 0 260195 BAAB BAAB 2026-03-06 200064671 0 200064671 2026-03-06 00:36:31 2026-03-06 ARTICULO
