Foraminiferal biostratigraphy, Limboto LimestoneAbstract
The limestone research within the Limboto Basin of Gorontalo Province becomes a new challenge, particularly for the study of planktonic foraminiferal biostratigraphy. This study uses the data obtained from the measured section in the northern part of Limboto Lake. The purpose of this study was to determine the planktonic foraminiferal biozonation and the absolute age of Limboto limestones. The analyzed planktonic foraminiferal fossils can be classified as well to moderately preserved with many fossils, in the context of abundance, categorized as frequent to abundant. There are three recognized planktonic foraminiferal biozones which are proposed to follow the standard biozonation: two biozone for Miocene age (M13b and M14) and one biozones for Pliocene age (PL1). The results of this study can be a reference to propose a new formation called as Limboto Limestone Formation that was previously known as Clastic Limestone Formation and Coral Limestone Formation. Determination of the Limboto Limestone Formation is based on the time interval and relative age of the formation.
