This book was released on 2000 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper examines possible stratigraphic linkages across the central Wabigoon Subprovince in north-west Ontario, based on a revised interpretation of the Obonga greenstone belt. After a review of previous mapping & interpretations, the paper presents information on stratigraphy & structure and on lithologies in the various zones or assemblages of the Obonga belt, and discusses outstanding research issues to be resolved. Finally, possible correlations among the Obonga, Sturgeon-Savant, and Onaman-Tashota belts are explored.

This book was released on 2000 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report first reviews the literature on the geology & geochronology of Mesoarchean and Neoarchean rocks in the central Wabigoon Subprovince. It then presents findings of analyses of neodymium isotope ratios found in samples from those rocks. The results are discussed with reference to those parts of the study area that have recycled crustal components. Mantle sources and the possible tectono-magmatic setting of rocks in the Neoarchean greenstone belts in the Subprovince are also suggested.

Book excerpt: This study used major & trace-element geochemistry to characterize the granitoid rocks of the Shikag-Garden lakes area of northern Ontario and to examine their petrogenesis & tectonic setting. Neodymium isotopes were examined to examine crustal recycling and to estimate the age of crustal sources contributing to the granitoid rocks. The data are subsequently interpreted to shed light on the distribution of basement terranes in the central Wabigoon Subprovince.

This book was released on 2002 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Nanisivik deposits are Mississippi Valley-type Zn-Pb-Ag massive sulphide bodies hosted by Mesoproterozoic dolostone of the Society Cliffs Formation. This work, undertaken during the summer of 2001, included detailed mapping in the immediate vicinity of the Nanisivik mine, regional mapping, and examination of accessible sulphide showings, and was undertaken to characterize the stratigraphy and develop a regional model for the mineralization. This project bridges the gap between deposit-specific and regional studies. In addition to generating new concepts, this paper integrates previous work into a coherent model explaining the genesis and distribution of massive sulphide bodies in the Nanisivik area.

This book was released on 2004 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dolostone mounds over 200 metres thick and over four kilometres across developed in deep water during uppermost Arctic Bay Formation shale deposition in the north-west Milne Inlet Graben on northern Baffin Island. This paper describes the geometry of hitherto unrecognized mounds that have been identified from field work in five areas: the Saint Georges Society Cliffs near Arctic Bay; beneath the Nanisivik lead-zinc deposit; Red Rock valley; Magda Lake; and Bellevue Mountain. Their lithology, lateral facies relations, and internal composition are described and an interpretation of the origin & growth of the mounds is offered. Finally, implications of mound growth & distribution for the fault-related flow of mineralizing fluids and consequent base-metal deposition are discussed.

Book excerpt: A well-exposed section about 250 metres wide below the high water line of the Jennings River, Teslin Lake map area in northern British Columbia shows part of the Teslin Fault and provides an opportunity to constrain the fault's kinematic history by direct ground observations. This report describes preliminary structural observations of this section of the Teslin Fault, including the rock types involved, mylonitic & ultramylonitic structures, and deformation. Indications of two main episodes of shearing are discussed.
