CHARACTERIZATION OF CLASTIC SEDIMENT: APALYNOFACIES APPROACH

摘要

Palynofacies as a tool for identification of depositional environment is broadly used in oil and gas exploration. Palynofacies study is integrated with palynology study, yet they can stand as independent and separated studies. Many palynofacies applications are presented in geology and one discusses in this paper is characterization of clastic sediment. The origin of organic matters as palynofacies analysis objects and its classifications is actually the first step in characterization of clastic sediment.Sample of sediment are characterized by the absolute and relative proportion of structureless amorphous material, dinoflagellate cyst, foraminiferal test lining, resin, black debris, yellow brown fragment, dark brown fragment, cuticle, plant tissue, woody material, pollen, spore and fungal and relative proportion as mentioned by Tyson (1995).Recently, palynofacies trends can be related to sequence stratigraphy in order to provide an outline of predictive model for more detailed investigations.
