(Robert Howard), 1957- Reconnaissance geological mapping and thematic studies of the Elu Basin, Nunavut [electronic resource] / [by] R.H. Rainbird and A. Ielpi.

The Elu Basin is in the Kitikmeot Region of Nunavut, Canada, contains rocks of ca. 1.9-1.6 Ga age. These rocks consist of sandstone considered to have been deposited by ancient rivers. Sandstone is topped by carbonates deposited along the shelves of a shallow sea. Similar rocks exposed elsewhere in Northern Canada already demonstrate vast potential for the extraction of uranium, as well as of a suite of industrial metals. However, despite some reconnaissance mapping performed in the 1970s, the economic potential of the Elu Basin is still largely unknown. During the summer of 2014, the initial phase of the Elu Basin Geoscience Project focused on mapping and analyzing a set of sandstone packages that could host economic deposits. Mapping was assisted by sampling for natural radioactivity using portable instruments, and followed by laboratory analyses. Concentrations of economic minerals were found within accumulations of pyrite and chalcopyrite. These results emphasize the efficacy of both field-based analysis of natural radioactivity and of bulk-rock sampling. gccst Sedimentary rocks gccst Stratigraphy Ielpi, A. Canada.
