| Abstract: | Determination of the timing of oil/gas entrapment is of great practical significance in guiding oil and gas exploration. Numerous methods have been developed to accomplish this task. K|Ar dating of illite is just one of them. Since this technique can yield an absolute age, it has received a greater attention. However, there exist certain problems and assumptions associated with the K|Ar dating technique in interpretation of the dating data, which may lead to incorrect conclusions. This paper documents these problems and assumptions, gives several examples involving K|Ar dating data, and discusses the application of K|Ar dating data to the interpretation of the timing and nature of hydrocarbon charging of reservoirs. |
