Facies, Facies Association, and Depositional Environment of The Klapanunggal Formation, Klapanunggal District, West Java

The research focuses on the Klapanunggal Formation, composed of limestone in the West Java Basin, specifically in the Klapanunggal area, Klapanunggal District, Bogor Regency, West Java Province. A massive limestone outcrop was found in this location. The method used is field data collection, stratigraphic cross-section measurement, and petrographic analysis. It aims to determine the facies characteristics, depositional environment, and association of the limestone facies of the Klapanunggal Formation. The results obtained from macroscopic and microscopic descriptions resulted in six (6) facies: Skeletal Wackestone, Skeletal Packstone, Benthic Foram Grainstone, Skeletal Rudstone, Coral Rudstone, and Bindstone. Then, the facies are classified into facies associations, resulting in three (3) facies associations: Platform Interior (Open Marine), Platform Margin Reef, and Slope.
