This 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.

The Arctic zone of the Earth is a major source of mineral and other natural resources for the future development of science and technology. It contains a large supply of strategic mineral deposits, including rare earths, copper, phosphorus, niobium, platinum-group elements, and other critical metals. The continued melting of the sea ice due to climate change makes these resources more accessible than ever before. However, the mineral exploration in the Arctic has always been a challenge due to the climatic restrictions, remote location, and vulnerability of Arctic ecosystems. This book covers a broad range of topics related to the problem of Arctic mineral resources, including geological, geochemical, and mineralogical aspects of their occurrence and formation; chemical technologies; and environmental and economic problems related to mineral exploration. The contributions can be tentatively classified into four major types: geodynamics and metallogeny, mineralogy and petrology, mineralogy and crystallography, and mining and chemical technologies associated with the exploration of mineral deposits and the use of raw materials for manufacturing new products. The book can be of interest for all those interested in Arctic issues and especially in Arctic mineral resources and associated problems of mineralogy, geology, geochemistry, and technology.
