The research area is located in the southern part of Gorontalo in the Tanjung Kramat Region, Gorontalo City, Indonesia. The regional stratigraphy of the Tanjung Kramat area refers to the regional geological map of the Kotamobagu Sheet, which is composed of two rock formations in order of formation from the oldest to the youngest, namely the Pinogu Volcano Formation (TQpv) and the Reef Limestone Formation (Ql). Research on limestone in the southern part of the Tanjung Kramat Region, Gorontalo City, and south Gorontalo has never been carried out, so this research is very interesting because it yields new findings. For this reason, this study aimed to analyze the relative age of the limestone in the Tanjung Kramat area, Gorontalo City, based on the content of planktonic foraminifera fossils. The research method used was a field geological survey and micropaleontological analysis (which contained planktonic foraminifera fossils). The results showed that the limestone facies consisted of three: wackestone, packstone, and coralline floatstone. Meanwhile, the results of the micropaleontological analysis showed that the planktonic foraminifera fossils in the study area consisted of 11 species, which refers to the results of quantitative analysis by overlaying the age range of each species. Finally, the relative age of the limestone, namely the Early Pliocene (N18-N19), is known. © National Academy of Sciences of the Republic of Kazakhstan, 2024.
