Planktonic foraminifera, age of sediments and polarity reversals, New Britain, Papua New Guinea

Samples from the Rudiger Point-Cape Ruge area, New Britain, are not from a conformable late Miocene-earliest Pliocene sequence, as was presumed by previous workers, but rather are of two age groups, one of general middle Miocene age, and a younger group of late Miocene age. A sample of volcanolithic sandstone, NG34B, is of late Pliocene-middle Pleistocene, Zone N.21-Zone N.22, age; this is the youngest marine sediment yet recognised in New Britain. Planktonic Zone N.18 is correlated, at least in part, with a normally magnetised interval.
