DOWNLOAD EBOOKThis volume contains four papers that report on a wide range of geoscientific activities related to various rare-metal deposits in the Northwest Territories. Two papers represent the results of work carried out on the Blatchford Lake intrusive suite and the associated Thor Lake rare-metal deposits of niobium, tantalum, beryllium, yttrium, rare-earth elements, and gallium. A detailed gravity survey and computer modelling provides an understanding of the three dimensional geometry of the 23 km wide Blatchford Lake. Another paper summarizes some of the extensive pegmatite research done by the University of Manitoba in the Northwest Territories during the 1980s, providing information on the geological setting, geochemistry, and economic potential of four previously undocumented or poorly known rare-element pegmatite occurrences at Ayler Lake, Torp Lake, Chantry Inlet, and the Foxe fields in the Rae Province. Another paper presents a thorough documentation of the geological settings, characteristics, and metallogeny of selected mineral occurrences in the southern part of the Proterozoic Great Bear magnetic zone.
