Abstract: Document concerning a scientific report on the age constraint of the obduction of ophiolitic rocks in Yap Island, located in the Philippine Sea. The report utilizes nannofossil analysis to determine the timing of geological events. The geographic focus includes Yap Island and the surrounding Philippine Sea region, with explicit reference to Micronesia through the inclusion of Yap Island. The time period addressed pertains to the geological era relevant to the formation and obduction of ophiolitic rocks, as inferred from nannofossil data. The document is structured as a research report presenting stratigraphic and paleontological data to establish chronological constraints. The subject domains covered include geology, paleontology, stratigraphy, and marine geology, with emphasis on tectonic processes and fossil analysis. The report includes detailed taxonomic identification of nannofossils and their stratigraphic distribution to support age determinations. The study contributes to understanding the geological history of the Philippine Sea region and the tectonic evolution of Yap Island within Micronesia. The document is a primary research article likely published in a scientific journal, containing empirical data, methodological descriptions, and interpretive discussion related to the obduction process of ophiolitic rocks.
