The miocene carbonates in time and space on- and offshore SW Palawan, Philippines

Rehm, Stefan K.

Miocene carbonates have been studied on Palawan (Philippines), and compared to coeval deposits offshore. The interpretation of wells and seismic lines offshore SW-Palawan yields the depositional model: 1) Early to Middle Miocene platform carbonates overly unconformably Cretaceous to Lower Tertiary clastics; 2) some isolated reefal structures of different sizes occur on top of the platform; 3) the carbonates are covered by Late Miocene to recent clastics that display prograding sequences and erosional channels. The discovery of new outcrops of late Early Miocene to Middle Miocene platform carbonates and isolated reefal structures in SW-Palawan represent a similar development onshore, whereas the evolution is associated with a general increase of the relative sea level. The onshore carbonates in SW-Palawan are equivalent to the Miocene carbonates offshore and correlate with the stage of build-up development offshore. They provide, therefore, new insights in the development and facies distribution within Cenozoic build-ups.
