Abstract
- Nannofossil analyses of this study was carried out of Kalibeng river section, Plandaan, Jombang, east Java. This study included of the Kendeng Zone, East Jawa Basin. This research method through 2 section of the Measurement Section, and sampling a number of 32 samples. Analysis used of smear slide and Scanning Electron Microscope analysis. The result of the analysis of there are twelve genera and forty-three species. The stratigraphy of this area consists of 3 lithostratigraphic units, namely from old to young: Marl Unit of Kalibeng Foramtion (CNM20-CNPL6/Late Miocene to Early Pliocene), Calcareous Sandstone Unit of Sonde Formation (CNPL6-CNPL8/Late Pliocene to Pleistocene), and Calcareous claystone unit of Sonde Formation (CNPL9-CNPL10/CNPL11?/Pleistocene. The nanoplankton biostratigraphic zone are arranged into 11 zones consisting of 2 Partial Zones, 10 Interval Zones. Development of sedimentation rate (RoS) of this study, there are 11 periods. The periods are (1) CNM20 Zone/Late Miocene to Early Pliocene /1.4 cm/ky), (2) CNPL1 Zone /Early Pliocene (8.44 cm/ky), (3) CNPL2 Zone/Early Pliocene (9.7 cm/ky), (4) CNPL3 Zone/Late Miocene-Early Pliocene (90.91 cm/ky), (5) CNPL4 Zone / Late Miocene-Early Pliocene (4,26 cm/ky), (6) CNPL5 Zone/Middle-Late Pliocene (8.57 cm/ky), (7) CNPL6Zone /Late Pliocene (13,26 cm/ky), (8) CNPL7 Zone/ Late Pliocene to Early Pleistocene (14.95 cm/ky), (9) CNPL8 zone /Early Pleistocene (26.42 cm/ky), (10) CNPL9 Zone/Early Pleistocene (3.11 cm/ky) (11) CNPL10 Zone/Early-Middle Pleistocene (1.34 cm/ky). In this study there is a fast sedimentation process, namely in the CNPL3 Zone which has a sedimentation rate of (90.91cm/ky), very thick thickness sedimentasion (200 m) and with a short time duration of (0.22 my). There are 2 unconformities, namely Top of the CNPL2 Zone (Late Miocene) and Top of CNPL7 Zone (Early Pleistocene) [ABSTRACT FROM AUTHOR]
