This research is based on observations of coal deposits that are located at Missim area, Tabalong Regency, South Borneo Province. The area of this research is located within Barito Basin Area. Moreover, this basin is bordered by several basins which are Kutai Basin on the northern part, Asem-Asem Basin on the eastern part, East-Java Basin on the southern part and Schwaner Complex Arc on the western part. Meanwhile, this area has NE-SW structural features that are related to two different tectonic regimes; Early-Tertiary tensional regime and Mid-Miocene to Plio-Pleistocene compressional regimes. According to contour morfology, this research area has four different geomophological units which are Homoclinal Ridge Unit, Synclinal Valley Unit, Sinclinal Ridge Unit and Intrusion Ridge Unit. Stratigraphically, this research area is covered by four different units of lithology. Consecutively start from the oldest units, this area is composed by Andecite Unit, Sandstone Unit, Claystone-Sandstone Unit, Claystone Unit and Limestone Unit as the youngest one. Furthermore at this location, coal deposits are particularly observed as parts of Sandstone Unit and Claystone-Sandstone Unit which are members of Tanjung Formation. The distribution pattern of coal deposits followed stratigraphic distribution of those rock units. According to proximate approach analysis, observed coal deposit in this area has (adb) 6241-6741 Cal/g calorie level, therefore it can be classified as Bitumionous Coal High Volatile A – Bitumionous Coal High Volatile B level. The average tickness of coal deposits starts from 30 cm to 95 cm. Lastly, based on resources calculation approach, this research area has 747.754,22 tons of measured coal resources and 4.057.156,32 tons of indicated coal resources.
