Abstract

In the moment of Merangin Jambi Geo-park in sustainability UNESCO Global Geo-park. Therefore, it is necessary to socialize the current situation and development of geopark, through publications in the form of geohistory and storytelling at each geosite. One of those geosites is the Teluk Gedang Wood Fossil. The located in the Air Batu Village and Near Batang Merangin River. Taking data at the stage of geological survey on geological outcrop of Teluk Gedang Wood Fossil, and then important information from the public regarding the folklore that developed at the geological site. Geological data and analysis will be information geological characterized, such as rock type, stratigraphic succession, structural geology as deformation, tectonic story through global tectonic basement approach, and those get geohistory. The folklore obtained from public information will be deep information of unique of geological site. A integration of these two points of view to acquire storytelling concept. On the Teluk Gedang is the beginning of Mengkarang facies stratigraphy. It consists of sediment-volcanic rock, which are lacustrine facies and shallow marine facies of claystone and tuffaceous sandstone with Araucarioxylon, carbonifereous claystone, tuffaceous claystone, silstone, and tuffaceous sandstone with limestone with brachiopods and gastropods fossils intercalation. Araucarioxylon Wood Fossil is a uniqueness of this geological site, which has geometry about 2.6 m hight and 1.4 m wide diameter. This fossil has grown in sediment-volcanic rock, so it has a shape like a large backrest. According to folklore there, this geological site used to be a bathing place for the lost princess of the Air Batu village a long time ago. With the uniqueness of this geological site, it really meets the criteria as geoheritage with geohistory to build a narrative between geoheritage and folklore that produces a storytelling concept
