| Resumo |
Concretions of manganese have been discovered by the geological expedition to the islands of the Timor group in 1910-1912 in triassic and jurassic deep-sea deposits, on the Island of Timor, and also well developed in similar jurassic deposits on the island of Rotti, and previously, in 1894, the author noticed them in abysmal deposits of the pre-cretaceous probably jurassic Danau formation, occurring in West and East Borneo. On the island of Rotti nodules of manganese were found in several localities in siliceous limestones, marls, siliceous and calcareous clayshales along with concretions and nodules of chert of jurassic age, full of tests of radiolaria. |
