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

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