Applications of Biomarkers to Determine Maturity Level of Coal from Tanjung Formation and Pamaluan Formation, Muser Area, East Kalimantan

Dyno Triandika Diputra, Ahmad Helman Hamdani

Abstract: The Tertiary coal from Tanjung Formation and Pamaluan Formation exposed in the Muser, East Kalimantan, were organic geochemistry analyzed, and their maturity level were interpreted. This is commonly provide information about the direction of migration, deposition environment, and level of maturity. The level of coal maturity of Tanjung Formation and Pamaluan Formation were distinguished by CPI value of 1, 22 3.53, C30 moretane/hopane ratio of 0.32 0.35, Tricyclic / 17-hopane (0.04 -0.12), Drimane /Homodrimane ratio of 0.27 -2.19, C29aaa20S / C29aaa20R (1.21-0.59), MPI (0.55-0.43), TNR (0.67-0.53). All these biomarker maturity parameter data show that all samples are thermally early mature to mature. The coal of Tanjung formation was more mature than Pamaluan coal Formation.
