A clearer idea about the distribution of total amino acid content has been obtained through its quantitative determination in various geological bodies. Because amino acid content is strongly correlated with organic carbon content in the same sedimentary rock, therefore, an attempt has been made to use their ratio to distinguish the primary types of biological debris in sediment. In addition, the quantitative determination of individual amino acids has been also carried out on several specimens from ancient sedimentary rocks, and the results show that their amino acid pattern is almost similar to that of the recent sedimentary muds. 相似文献

The technique of differential thermal analysis is widely used to investigate dispersed organic matters present in sedimentary rocks in an attempt to interprete some problems concerning petroleum geology. In our practice, sufficient separation of organic matters from the mineral matrix has been made and DTA curves measured.On the basis of the characteristie of DTA curves, the classification of the types of organic matters has been done and a series of indexes developed to determine the degrec of metamorphism of organic matters as well as the possible direction of oil migration, thus providing reliable clues to the promising regions for petroleum exploration. Since various factors would act on DTA curves during experiments, correct and comprehensive interpretation of DTA results still await further investigation. 相似文献

The chemistry of organo-clay in somc Tertiary clay-stones from the northern part of the South China Sea was studied. The preliminary results are summarized as follows : (1) Three basic types of organic matter are distinguished in the claystones after treated with different chemical agents: spluble, combined and insoluble (kerogen). It is suggested that the distribution of organic matter and its conversion to petroleum are closely related with the composition and structure of expansive clay minerals in the claystones. Therefore, more detailed studies of these expansive clay minerals may provide new indices for oil-generating potentiality. (2) It is considered from the study of the state of existence of organic matter and. of organo-clay complexes in tile clay-stones that the accumulation and preservation of organic substances may substantially take the form of organo-clay complexes in the process of sedimentation and burial and that the organo-clay complexes may make considerable contributions to the formation of petroleum hydrocarbons during diagenesis. Studies in this aspect are of great significance in developing new theories conccrning petroleum generation and in localizing oil-generating occurrences. 相似文献
