| Resumo |
Fossil Mn nodules of Cretaceous age from western Timor exhibit chemical, structural and radioisotope compositions consistent with their being of deep-sea origin. These nodules show characteristics similar to nodules now found at depths of 3,500-5,000 m in the Pacific and Indian Oceans. Slight differences in the fine structure and chemistry of these nodules and modern deep-sea nodules are attributed to diagenetic alteration after uplift of enclosing sediments. |

Fig. 1 In situ location of Mn nodules. All were collected from the same surface exposure over an area of about 10 m. The site is 4.5 km ENE of Niki Niki in Indonesian Timor on a hillside leading down to the river Tobee (URI: hdl:10013/epic.46220.d001) Fig. 2 Photograph of Mn nodules studied here (URI: hdl:10013/epic.46220.d002) Fig. 3 Photography of internal structure of a Timor nodule showing concentric growth bands around a small central nucleus (URI: hdl:10013/epic.46220.d003) |
