Abstract:
Deep-sea deposits, which resemble in nearly every respect the deep-sea oozes have been observed in many islands of the East-Indian Archipelago, notably the islands of Borneo, Rotti and Timor. Manganese nodules are found in equivalents of deeep-sea red clays on Timor and Rotti island. In this paper, those relative to red clay deposits dating from a Cretaceous ocean are analysed in detail in the vicinity of the town of Niki Niki in Western Timor.

Comment:
From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions. At the time it was the most extended data compilation on ferromanganese deposits world wide. Initially published in a proprietary format incompatible with present day standards it was jointly decided by AWI and NOAA to transcribe this legacy data into PANGAEA. This transfer is augmented by a careful checking of the original sources when available and the encoding of ancillary information (sample description, method of analysis...) not present in the NOAA-MMS database.
