The scientific monograph mentioned above with 203 pages

123 figures and 16 plates written by the senior research fellow Huang Difan et al.of the Scien-tific Research Institute of Petroleum Exploration and Development

Beijing is recently published by the Petroleum Industry Press.In this book

the writers have deeply discussed the kernel problems such as the evolution of continental organic matter and its mechanism of hydrocarbon generation.Based on the simulating tests and plentiful data made by various modern experimental technology

they have summed up on a molecule and con-figuration level the results of geochemistry research of the institute in recent years.The type and its evolution characteristics of the organic matter in various mature stage

the biogenetic substances of hydrocarbon

the biomarker

the evolution model and mechanism of hydrocarbon generation of various organic matter have been discussed;some new ideas

such as the X-shaped diagram of kerogen pyrolysis classification

the relationship between the threshold of principal oil generation zone and the molecule parameters of sterane and terpane have been presented.The authors conclude in this book that the distributions of semi-deep and deep lacustrine facies developed in deep depression and its inheritance in geo-logical history are the essential requirements for petroleum generation in con-tinental sediments.The monograph is essentially a summary of their own research

the enor-mous excellent work made by other geochemists in China are less concerned.
