PALEOBATHYMETRY ANALYSIS OF LIMESTONE IN BONGOMEMEREGION BASED ON CONTENT OF BENTHICFORAMINIFERA FOSSIL,GORONTALODISTRICT, INDONESIA

The location of the study area is surging hills in Bongomene area, Gorontalo, Indonesia. In this study, a geological survey and sampling were taken, and then an analysis of the content of benthic foraminifera was performed in each sample. The study aims todiscover the species of benthic foraminifera fossils and to determine the paleobathymetry to the studied regions. The results of the analysis contained seven fossils species, namely Ammomassilina alveoliniformis, Stelligerum astrononion, Haynesia germanica, Nonion fabum, Praeglobobulimina ovata, Rhabdammina discreata andSaccorhiza ramosa.Based on the content of benthicforaminifera fossils, paleobathymetry is determined as Middle Shelfto Outer Shelfin Bongomeme 1, while in Bongomeme 2 and 3 is Middle Shelf.
