Scram. The island, about 2 km, is exclusively formed from black, grey to red silicified, recrystal- lised, generally brecciated radiolarian limestones.

Pink-red clays and marly-clays are associated with the limestones. Because of the poor preservation, radiolaria could not be used for biostratigraphy.

However, based on the palynological content, a Late Norian to Rhaetian age is suggested.

NNW from Sawai village. In the Asinepe Lime- stone, two dominant lithotypes are recognized: massive white micritic, occasionally oolitic, lime- stones showing a black patina on weathering surfaces. Large megalodonts (2Q cm) in life position occur at the base of the cliff. The second lithotype is a grey nodular sometimes bioclastic limestone, with
