Abstract
Indonesia coal have the coal-forming material (plants) as well as the parameters that are relatively the same deposition conditions (tropical) although it is located in the sprawling region Indonesia with diverse geological conditions, hence Indonesia is one of the significant coal producer in the world. Research site located in Muara Wahau, East Kalimantan, including the Upper Kutai Basin. Coal bearing formation in the area of Muara Wahau is Wahau Formation Late Oligocene - Early Miocene age. Laboratory analyses was conducted using method coal microscopy observations to determine vitrinite reflectance random (Rr) and maceral composition as well as method of Gas Chromatography-Mass Spectrometry (GC-MS) to determine facies, organic compound (biomarker), maturity and precursor of plant MuaraWahau coal. Maceral composition of the Muara Wahau coal is dominated by vitrinite maceral group, ranging from 76% to 82.4.0%. Liptinite maceral group accounts 0.4% – 1.8 %. The composition of inertinite maceral group ranges from 8% to 18.8%. Huminite reflectance of coal samples from Muara Wahau range from 0.44 to 0.45 Rr (%), according to huminite reflectance, all studied samples are low rank sub-bituminous coals. Maceral composition to detect coalbed methane potential. The presence of 2-series long chain n-alkane indicates the changes of peat forming facies condition from oxic condition (increasing odd carbon proportion) and anoxic condition (increasing even carbon proportion) Geological Outcrop along the Telen River and Wahau River, is the type locality of Wahau Formations, should become a geology conservation area in Muara Wahau as Geoheritage and it is very interesting to study geology. Key words: geology, coal; tropical; facies; high plants; long chains; oxic; anoxic; methane
