| Abstract | Two anomalous occurrences of primary uranium, thorium and rare earth elements in the Nueltin Lake area are associated with an aplite dyke and a pegmatitic seam. Both are hosted within the Nueltin
granite suite. The occurrences are rich in urano-thorite and allanite, which are also present in the host Nueltin granite. The aplite dyke is enriched in uranium (56.8 ppm) and thorium (787 ppm) and the pegmatitic seam is enriched in uranium (589.3
ppm), thorium (8461.4 ppm) and rare earth elements (total 86,153 ppm), an enrichment magnitude of 10-100 times relative to the host pluton. Parallel trending trace element patterns indicate that the anomalies most likely represent late-stage, highly
fractionated melts (fluids?) from Nueltin granite. |
