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.

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.

The North Caribou terrane is one of the largest blocks with continental affinities in the western Superior Province. This paper reviews field relationships at the southern margin of this terrane in the western Uchi belt between Trout Lake, north-west Ontario, and Lake Winnipeg, Manitoba. After an introduction on the regional geological framework, the paper describes the Trout Lake Batholith, the Red Lake-Garner Lake lobe, the Bloodvein-Wanipigow River corridor, the English Lake magmatic complex, and the eastern Lake Winnipeg area. Implications of the observations for crustal architecture are discussed.

Presents geochronological age determinations of zircons from eight plutons in the Grenville Province, Ontario (Oso and Mountain Grove plutons in the Sharbot Lake domain; Silver Lake & Bennett Bay plutons and Fall River mangeritic augen gneiss associated with the Maberly shear zone; North Crosby & Pike Lake plutons in the north-west sheared part of the Frontenac terrane; and the Beales Mills pluton in the interior of the Frontenac terrane). The results are used to propose a re-interpretation of the tectonics of the Frontenac suite and the origin of the magmas responsible.

Presents a geochronological and geochemical study of the Barbers Lake and McLean plutons in the Grenville Province of Ontario, including comparisons of whole-rock analyses of these plutons with the Elphin and Leggat Lake plutons. The assignment of various plutons in the study area to one of several age groups is discussed.
