الملخص
The kerogen content and thermal maturation of samples recovered from DSDP site 94 were studied in order to assess the hydrocarbon potential of the sediments. The studied samples cover ~126 m of section and are Middle Eocene to Early Miocene in age based on foraminifera and calcareous nannofossils. Two distinctive organic facies were recognized. Palynofacies A occupies the upper part of the studied section. It is dominated by amorphous organic matter but has few amounts of terrestrial phytoclasts and marine phytoplankton. Kerogen type II (oil prone) is suggested for this palynofacies. Palynofacies B represents the lower part of section and is dominated by terrestrial phytoclasts with common opaque particles. Kerogen type III (gas prone) is proposed for this palynofacies. Exine color of bisaccate pollen grains reflects fair to good thermal maturity (2 to 2+ TAI), indicating that each palynofacies is likely to produce the corresponding hydrocarbon type.
