Abstract
The Langer Heinrich and Klein Trekkopje U deposits are located within the Namib Desert in Central Namibia. Both deposits are hosted by calcretes developed within palaeo-channel systems of Tertiary age. The sources of both U and V in the two deposits and the reasons why the two deposits differ in terms grade and tonnage have remained unclear to many researchers. The study aimed to resolve these uncertainties. During the study, the geology of the area was reviewed and a number of research methods were employed. U and V concentrations and the mineralogy of various rocks in the catchment area were analyzed by ICP-MS, XRF and thin sections. Leachability of various rocks was studied through the analysis of mineralogy, texture, structures, etc. This study found that the Bloedkoppie granite, which is located in the catchment area for Langer Heinrich, contains about 5 – 15 ppm U and 5 – 20 ppm V. The Tinkas schist, which forms most of the bedrock in the catchment area for the Langer Heinrich deposit, contains 3 – 6 ppm U and 120 – 160 ppm V. The Bloedkoppie granite is considered to represent the source of U for the Langer Heinrich deposit. It is deeply weathered due to its relatively high proportion of ferromagnesian minerals, compared to average granites. The fluid which mobilized U and V from the Bloedkoppie granite also mobilized V from the Tinkas schist.
