Geological Setting and Geochemical Approaches for Uranium Exploration in Papua

With regards to the uranium exploration efforts in Indonesia, Papua is the area with least exploration activities
compared to other major islands. Several preliminary geological and geochemical surveys have been done, and
focused on the possible occurrences of the intrusive type uranium deposits. This paper is dealt with the research
results on the possible occurrences of other types of uranium deposits, including sandstone-and-carbonate-hosted and unconformity-related systems in Papua, which are in line with recent concepts and understanding of tectonic and basins formation/deformation. This research result suggested some anomalies which are related to sandstone uranium deposits in Tipuma Formation, and carbonate uranium deposits in Quaternary Mokmer Formation and Oligocene Wainukendi Formation.
