Download or read book Structural and Metamorphic Geology of the Walker Lake-Arrowsmith River Area, Committee Bay Belt, Nunavut written by Mary Sanborn-Barrie and published by Natural Resources Canada. This book was released on 2002 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Walker Lake-Arrowsmith River area of the Committee Bay belt, Nunavut, is dominated by three crustal domains: granite-greenstone belts in the central region, a granitic batholith in the south-east, and metasedimentary rocks in the north. Rocks within all domains display moderately to strongly developed strain fabrics & structures and preserve metamorphic mineral assemblages. This paper provides preliminary observations & interpretations of fabrics, structures, and mineral assemblages from this study area. It also presents preliminary monazite chemical ages from samples from the northern & central domains, and discusses the timing & tectonic significance of tectono-metamorphic events affecting the area.
