Abstract

Claystone is composed of clay and carbonaceous sandstone. The relatively age of claystone is Lower Miocene (N8 Zone) – Middle Miocene (N9 Zone). Based on quantitative analysis of benthic foraminifer fossils from 10 samples on Cikarang river line, there are 31 species and 480 individuals, meanwhile, from 6 samples of Cilegok river line, are found 20 species and 348 individuals. Percentages of benthic foraminifer fossils on Cikarang River are 94,8% Rotaliina, 2,71% Textulariina, 2,71% Milioliina. Cilegok river has 98,28% Rotaliina, 0% Textulariina, 1,72% Miloliina.The interpretation of Paleoecology was done by using fossil assemblages, Diversity Index α Fisher and Triangular Plot Murray. Based on those methods, paleoecology of claystone of Jatiluhur Formation of Cileungsi area was Normal Marine Lagoons.

Abstract

Location of seafloor sediment is Semarang waters (sheet map of 1409), Central Java. Geographically, research area is in coordinate 109°30'-111°00' and 06°00' - 07°00'.Twenty samples of two phi seafloor sediment were examined in order to know diversity of small benthic foraminifera. Based on quantitative analysis, small benthic foraminifera are composed of 7 Order, 27 Families, 38 Genus, 57 Species, and 235889 Specimen. The calculation of index diversity are shown between 0,3 - 1,

Abstract

Fossil of Foraminifera, Nannoplankton, and Pollen were got into rock sample in lower Kutai Basyn and very interesting to do research. Paleontology zone were made for deliniation of rocks formation in lower Kutai Basyn. Paleontology zone divided into three part : Foraminifera zone, Pollen zone, and Nannoplankton zone.

Abstract

Foraminifera is a unicellular animal which has capability to form a test. Twenty samples of seafloor sediment Semarang waters are analyzed by using quantitative method. Every type of small benthic foraminifera test wall is counted. Based on foraminifera test wall analysis, there are 3 types of test wall: hyaline calcareous, porcelain calcareous, and agglutinin. The highest percentage of hyaline test is found in 24 meter, porcelain test is found in 37 meter, and agglutinin test is found in 51 meter. Hyaline test wall has the highest total individual, 140226 individual (59,45%). It shows that research area is shelf environment.
