Sample 158147 - N19r - Locality 7 (Miocene to of East Timor)
Where: East Timor (8.9° S, 126.4° E: paleocoordinates 7.1° S, 131.2° E)
When: N19r foram zone, Late/Upper Miocene to Late/Upper Miocene (11.6 - 3.6 Ma)
Environment/lithology: marine; chalk
• Throughout the island, chalk and marl, in places containing tuffaceous material, form the basal part of the post-5.7 Ma succession (“Batu Putih” unit of van Bemmelen, 1949, Table 59; Carter et al.,1976, Fig. 5; but not of Charlton and Suharsono, 1990, p. 52) and are overlain by marl and mudstone with very slow sedimentation rates (Keep and Haig, 2010, Fig. 7). Foraminifera form almost all the sand fraction of the chalk and provide keys to interpreting the palaeobathymetry as well as the age. interbedded turbiditic sands and conglomerates (Viqueque Series of Grunau, 1956). The basal chalk represents pelagic carbonate ooze that accumulated at
