Iran boasts internationally important deposits of hydrocarbons. The hydrocarbons can be regarded not only as an exceptional energy resource, but also a geological heritage (geoheritage) resource. A new investigation of the Bangestan carbonate rocks from the Cretaceous age in the Fars Province has permitted to find several unique features and to assign these to six geoheritage types, namely sedimentary, palaeontological, stratigraphical, palaeogeographical, structural, and economic. The most important from these is the economic type that is ranked nationally. The Bangestan geoheritage is valuable for geoscience research, geoeducation, and geotourism, and this geoheritage is a subject of geoconservation. As these activities can bring some socio-economic benefits, this geoheritage has to be considered a true natural resource. Field studies have permitted to emphasize its appropriate manifestation in the Nowdan anticline (an area in the Zagros Mountains near the cities of Shiraz and Kazeroon), which is suggested as a geosite. Hydrocarbon-related industrial tourism and geotourism activities can be coupled for their mutual benefit. The Nowdan anticline geosite should be used for the purposes of tourism, but it requires some simple infrastructure building and involvement in excursion programs coordinated by a local museum or visitor centre.
