Stratigraphy
| Formation: | Nyalindung | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: Formerly referred to as Nyalindung Mbr of Cimandiri Fm (Sukamoto, 1990). Overlying Jampang Fm. THICKNESS: From ~2 m thick bed within <8 m section; total composite section thickness is estimated at around 40 m. AGE: Age still debated, but most evidence, including molluscan and foraminiferal biostratigraphy suggest a Middle Miocene age. STRATIGRAPHIC POSITION: From lower cycle 9 near base of the Nyalindung Fm. | |||||
