Abstract
The present study was carried out at the
Banyuurip area in the East Java Basin, Indonesia, a site
contains nannofossil assemblages of Pliocene to Pleistocene,
with lithology is suitable for nannoplankton research.
Methods used in this research include making a
Stratigraphical section Measurement, collecting 41 samples
and preparing the samples with the smear slides method to
be observed using a polarizing microscope with 1000x
magnification, and preparing several rock samples using
SEM analysis. Analysis of nannofossil resulted in identifying
19 genus and 51 species. Biostratigraphic zone of this study
can be arranged into 9 biostratigraphic zones. The zone
order from older to younger are: a) Sphenolithus neoabies
Zone /NN12/Late Miocene to Early Pliocene, b) Ceratolithus
rugosus Zone /NN13/Early Pliocene, c) Discoaster
asymmetricus–Reticulofenestra pseudoumbulicus Range
Zone/NN14-NN15/Early Pliocene to Middle Pliocene, d)
Discoaster surculus Zone/NN16/Middle Pliocene, e)
Discoaster pentaradiatus Zone/NN17/Late Pliocene, f)
Discoaster brouweri Zone/NN18/Late Pliocene, g)
Gephyrocapsa caribbeanica Zone/NN19 Zone/Early
Pleistocene, h) Gephyrocapsa oceanica Zone/NN20
Zone/Middle Pleistocene, and i) Emiliania huxleyi
Zone/NN21 Zone/Late Pleistocene
