[Ottawa] : Natural Resources Canada, 2017. [2] p. : col. ill. Issued also in French under title: Caractéristiques géoenvironnementales de gisements métalliques critiques Caption title. "April 2017." "The extraction and processing of critical metals such as niobium (Nb) and the rare earth elements (REEs) has led to environmental degradation in some parts of the world, but there are few published studies of these environmental impacts and related risks to human health. Recent studies in Quebec by the Geological Survey of Canada (GSC) are providing new geoscience knowledge on the geoenvironmental characteristics of Nb and REE deposits. This knowledge should help to reduce the environmental risks of future development of these important resources. This fact sheet provides an overview of this ongoing research in the LMS Environmental Geoscience Program"--Provided by publisher. Rare earth metals Strategic materials Environmental geology Canada.
