| Abstract: | Understanding of the hydrocarbon filling of the reservior is very important for hydrocarbon exploration. K-Ar dating of authigenic illite in reservior can provide very useful data of the hydrocarbon filling history. The separation of authigenic illite in hydrocarbon reservoirs and its K-Ar dating techniques are described in detail in this paper. Detrital K-bearing minerals such as potassium feldspar and illite in authigenic illite may lead to an erroneous age. For the samples with detrital potassium feldspar and/or detrital illite, it is necessary to find a way to remove the contribution created by these impurities, even at low levels, to the authigenic illite K-Ar age. This paper conclude a detailed study of the impact of contaminant phases on K-Ar age, and as a result, a data processing technique is developed and a new concept named "Corrected Age" is presented. |
