From 1982-84, the Ontario Geological Survey conducted an inventory of peatlands in 16 study areas across Ontario. Field investigations were performed by private-sector consulting firms, necessitating precise project specifications and a standardized approach. The first year's investigations were modelled on the New Brunswick and Finnish systems but were later modified. This report describes the 1984 field-work methods, covering field work, mapping and profiling, and report writing. Directions are given for both detailed and reconnaissance evaluations of the peat stratigraphy and peatland vegetation.

The map area is located east of Long Lake and comprises Daley Township and the eastern part of Ginoogaming First Nation Indian Reserve, formerly Long Lake Indian Reserve 77. Field work was carried out in summer 1988 and consisted of mapping the Precambrian bedrock and its mineral deposits. Rock samples were collected in the field, with 50 samples submitted for gold and silver assays, 40 for whole-rock geochemistry, and 88 for thin sectioning. This report describes the general geology, rock geochemistry, structural geology, metamorphism and alteration, geochronology, and economic geology of the area, including descriptions of existing properties, and the possibilities for gold, silver, base metals, iron, corundum, stone, and sand and gravel.

Nickel Sulfide Ores and Impact Melts: Origin of the Sudbury Igneous Complex presents a current state of understanding on the geology and ore deposits of the Sudbury Igneous Complex in Ontario, Canada. As the first complete reference on the subject, this book explores the linkage between the processes of meteorite impact, melt sheet formation, differentiation, sulfide immiscibility and metal collection, and the localization of ores by magmatic and post-magmatic processes. The discovery of new ore deposits requires industry and government scientists and academic scholars to have access to the latest understanding of ore formation process models that link to the mineralization of their host rocks. The ore deposits at Sudbury are one of the world's largest ore systems, representing a classic case study that brings together very diverse datasets and ways of thinking. This book is designed to emphasize concepts that can be applied across a broad range of ore deposit types beyond Sudbury and nickel deposit geology. It is an essential resource for exploration geologists, university researchers, and government scientists, and can be used in rock and mineral analysis, remote sensing, and geophysical applications. - Provides the only reference book to focus entirely on the Sudbury Igneous Complex - Brings together an understanding of ore deposit and impact melts as a basis for future exploration - Authored by a leading expert on the geology of the Sudbury Igneous Complex with 35 years of experience working on nickel sulfide ore deposits

This study examines aspects of the geological evolution of the Sharbot Lake domain and compares it with that of neighbouring domains & terranes in the Central metasedimentary belt, Grenville Province, Ontario. The study reports uranium-lead zircon & titanite geochronological ages for a granodiorite phase of the Pakenham intrusion from the northern part of the Sharbot Lake domain. The new data expand the known range of magmatism in this part of the belt, elucidate the early tectonic evolution of the domain, and constrain the timing of overprinting metamorphism. Possible links between the Pakenham structure and the Wolf Grove structure to the south-east are also discussed.
