According to the steady-state catalytic model for the origin of light hydrocarb on proposed by Mango, 2,4-/2,3-dimethylpentane ratio is a pure temperature par ameter. Bement and Mango et al. established the functional equation between the light hydrocarbon temperature parameter and the burial temperature and applied i t to the calculation of hydrocarbon-generating temperature, which provide a new choice for oil maturity research. In this paper, the generating temperature of hydrocarbons from the Melut Basin are calculated, the result indicate that oil m aturity in the block 3 and 7 is the lowest, the block 4 is the highest, and the block 6 is in the middle.
Key words: Light hydrocarbon; Hydrocarbon generating temperature; Maturity.
