| Abstract | (unpublished)
This report provides new rare earth element (REE) data from Permian through to Late Cretaceous sedimentary rocks of the Sverdrup Basin, along with focused analyses on phosphate
nodules that occur in the Middle Triassic Murray Harbour Formation. Results show the overall sedimentary values are low, however phosphate nodules are highly enriched in REEs. |
| Summary | (Plain Language Summary, not published)
This study provides the first assessment of rare earth element abundance through a sedimentary profile spanning a significant age range. Results show
that while sedimentary rocks are normally low in rare earth elements, periods of phosphate deposition are highly enriched. These potentially form attractive resources as extraction of rare earth elements from phosphates is simple and has low
environmental impact compared to other resource types. More work is required though to define the total resource potential. |
