The radioactive anomalies finding in Rantedoda area, Tapalang sub-district, Mamuju, West Sulawesi, give a clue that there are potential of mineral this area. In Botteng, Takandeang, and Hulu Mamuju area davidite ((U, Ce, Fe)2(Ti, Fe, V, Cr)5O12), thorianite (ThO2), britholite (Ce, Ca, X)5(SiO4)3(OH), thorutite (Th, U, Ca)Ti2(O, OH)6, monazite (REE, Th(PO4)) were found as primary minerals, meanwhile gummite (UO3.nH2O) autunite (CaO.2UO3.P2O5.8H2O) secondary minerals. Analysis uranium thorium...
Mamuju is one focus area of radioactive mineral exploration in Indonesia. For almost a decade, geology, geochemistry, and geophysical activities were conducted the area. To estimate uranium thorium undiscovered resources area, quantitative 3-part assessment applied. The form assumes that resources, contained deposits particular geological type, can be quantified using statistical distributions characterize grades, tonnages, spatial distribution known same type. assessments include three...
Rare Earth Elements (REE) and Uranium (U) are found in several locations West Kalimantan. The presence of this strategic mineral becomes a fascinating object to study. Tanah Merah is potential sector Kalimantan which contains uranium rare earth metals. Geological mapping, mineralization observations, sampling elements bearing ore have been carried out by geological geochemical mapping determine the research area. Geologically, source rock study area meta-silt, quartzite, mica schist, igneous...
Tebidah Formation is a 20,000 km wide and 1,000 m thick sedimentary rock in Melawi Basin.
