Bedrock Geology of Ontario Miscellaneous Release Data 126 (2006)

Date: 2006
Creator: Ontario Geological Survey

Projection:
Scale:
Access: web and CD ROM [251]
Description:
The Bedrock Geology Data Set is a Geological map of the Province and shows the distribution of bedrock units underlying Ontario. It illustrates geological rock types, major faults, iron formations, Kimberlite Intrusions and dike swarms. The geology of the Province consists of Precambrian rocks of the Canadian Shield and Phanerozoic sedimentary rocks in basins that overlie the Canadian Shield. Based on differences in age, metamorphism and tectonic setting, the Precambrian rocks are subdivided into the Superior, Southern and Grenville provinces. The Phanerozoic rocks occur in four basins. Major faults and shear zones are also included. The legend is subdivided geochronologically in the Phanerozoic, but geochronometrically in the Proterozoic and Archean. The Archean rocks of the Superior Province are subdivided into lithologic units. Supracrustal units of the Southern Province and the Phanerozoic Eon are subdivided lithostratigraphically. The Grenville Province is subdivided into major tectonic blocks and within each block the legend is mainly lithologic, with only part of the supracrustal rock record subdivided into lithostratigraphic units. The dataset is an overview of this geology on a Provincial Compilation scale of 1:250 000 and it illustrates geological rock types, major faults, iron formations, kimberlite and dike swarms.

Tectonic Assemblages of Ontario Seamless Coverage Data Set 11, 1993. (1993)

Date: 1993
Creator: Ontario Geological Survey
Datum: NAD 27
Projection: Lambert Conformal Conic
Scale:
Access: CD-ROM [253] or CD-ROM [263]
Description:
The Tectonic Geology Data Set is a digital interpretation of the Tectonic Geology of the Province of Ontario, It illustrates this by 1) grouping volcanic and sedimentary rock units into tectonic assemblages in Precambrain terrains and depositional sequences in the overlying Paleozoic and Mesozoic sedimentary basins; and 2) interpreting the ranges of emplacement ages of all major intrusions and grouping some plutons into suites. Among a range of tectonically significant features, the map also displays major folds, faults, stratigraphic younging directions, interpreted centres of volcanism and locations of U/Pb age determinations, which are numbered and cross-referenced to a table of ages. This map represents the first attempt internationally to subdivide Archean rock units into Tectonic assemblages, and the first attempt in Ontario to subdivide Paleozic and Mesozoic rock units into depositional sequences. The purpose of this map is to portray the distribution of magmatism and sedimentation in time and space in the rock record of Ontario. The intended user is a geologist with an academic or applied mineral exploration interest in the components of the bedrock of Ontario that forms the basis of its geochronometric and tectonic record.
