Abstract
Abstract. Nannofossil analyses of Miocene to Pleistocene, the section of Nglebur River, Jiken, Blora of Central Java
included of Rembang Zone, North East Java Basin. This study uses 70 samples from this section. The result of this
analysis consists of 18 genus was obtained with 57 species of nannoplankton. The research method used in field study
(measure section) quantitative analysis. The samples from taken include fine-grain stone (marl, shale) and carbonaceous.
The river section that has been selected consist of a continuous sediment sequence from Miocene (Wonocolo, Ledok, and
Mundu Formation) to Pleistocene (Lidah Formation). The sample preparation uses the smear slide method and species
determination uses Nannotax3 determination. The biostratigraphy consist of 11 zones, and there consists of 2 Partial
Zones and 9 Interval Zones. These Zone are Discoaster hamatus Partial Zone/NN9, Interval Zone of Discoaster
hamatus–Discoaster quinqueramus /NN10, Zone of Discoaster quinqueramus /NN11, Zone of Discoaster
quinqueramus–Ceratolithus rugosus/NN12, Zone of Ceratolithus rugosus–Discoaster asymmetricus/NN12, Zona of
Discoaster asymmetricus–Pseudoemiliania lacunosa/NN14, Zona of Pseudoemiliania lacunosa with Reticulofenestra
pseudoumbilicus/ NN15, Zona of Reticulofenestra pseudoumbilicus with Discoaster surculus/NN16, Zona of Discoaster
surculus–Discoaster asymmetricus/NN17, Zona of Discoaster asymmetricus–Discoaster brouweri/NN18, and Partial
Zone Discoaster brouweri and Gephyrocapsa caribbeanica/NN19
