摘要：

The relationship between the distribution of benthic foraminifera and sediment type and depositional environment in the Arabian Sea is discussed. The benthic foraminiferal fauna were sampled in nineteen Recent surface sediment samples, and geochemical variables of the sediment of the same samples were measured. The water depths for the box core samples varies from 440 to 4040 m. A total of 103 species and six species-complexes were identified. The geochemical properties were found to correspond well to the sediment type and depositional environment and six different sediment/depositional environment types could be distinguished. Analysis of the benthic foraminiferal fauna reveals specific faunal assemblages that are closely related to these sediment/depositional environment types. © 1990.
