Abstract: The effects of the chemical turbulence of the negentropy and self-organization periodic oscillations and aperiodic alternating appearance can be caused by the material exchange and energy exchange among the absorbed substances of clay mineral crystal laminas, such as metal cations, water molecules and organic matters, etc. in the source rocks in open complex systems of nonequilibrium. This brings about splitting and reassembly of organic matter and forms a new hydrocarbon with n-alkane peaks in order series.

Key words: n-alkane peaks, dissipative structure, nonequilibrium system, negentropy, self-organization
