You may have noticed that the GeologyOntario Web site has undergone a significant change. Redesigning the site was necessary to complete important hardware upgrades and meet the requirements of the Accessibility for Ontarians with Disabilities Act (AODA).

The site’s search functionality has been simplified and features different search functions and capabilities. All the information, data, reports and maps previously archived on GeologyOntario is still available to our clients. A help page is featured on the new site to help clients use the new search functions. Redesigning the GeologyOntario platform is part of our commitment to ensure that Ontario Geological Survey information and services are accessible for all Ontarians. This includes providing services and programs that people with disabilities can use and benefit from equally and in a manner that respects their dignity and independence. The OGS will continue to strive to be a global leader in the development of geoscience data through the publication of maps, reports and digital data on Ontario's geology.

If you require more information or assistance on navigating the new GeologyOntario site, please contact Digital Data Specialist Alphons Evers at (705) 670-5740.

Precambrian Geology – Northwestern Ontario

Miscellaneous Release—Data 349
Petrology and Geochemistry of the Neoarchean McKenzie Granite, Northwestern Ontario; by A. Hughes, P. Hollings, M.C. Smyk, M.A. Puumala and D.A. Campbell. This digital data release includes whole-rock and trace element analyses for 16 samples of felsic igneous rocks from the Neoarchean McKenzie granite, located near Thunder Bay in northwestern Ontario. The geochemical data are provided in a Microsoft® Excel® 2010 (.xlsx) workbook file. A general description of the units sampled, and their petrography, are provided in the readme file. These results form part of an Honours BSc thesis study that was a collaborative project between Lakehead University and the Ontario Geological Survey. This data release consists of 1 Microsoft® Excel® 2010 (.xlsx) and 2 portable document format (.pdf) files on 1 CD. $20.00.

Precambrian Geology – Far North

Miscellaneous Release—Data 347
Lithogeochemical Data, Magnetic Susceptibility Data and Outcrop Photographs from the Winiskisis Channel, McFaulds Lake and Highbank Lake Areas, “Ring of Fire” Region, Northern Ontario; by R.T. Metsaranta. This data release provides lithogeochemical data, magnetic susceptibility data and outcrop photographs collected and compiled as part of a multi-year (2010 to 2014) compilation and bedrock geology mapping project designed to better understand the geological context of various new metal discoveries in the “Ring of Fire” region of the James Bay Lowland. The data are associated with, and complement, OGS Preliminary Maps P.3804, P.3805 and P.3806 and also MRD 343. The data are provided as 3 Microsoft® Excel® (.xlsx), 1447 photographs as .jpeg, and 2 documents as portable document format (.pdf) files. Available on 1 DVD. $25.00.

Precambrian Geology – Proterozoic and Grenville Province

Open File Report 6330
Insights into the Tectonic and Metamorphic Architecture of the Composite Arc Belt and the Frontenac–Adirondack Belt near Perth, Ontario, Grenville Orogen: A Geological Guidebook; by R.M. Easton, 54p. $9.55.

Groundwater Studies

Groundwater Resources Study 16
Discrete, High-Quality Hydraulic Conductivity Estimates for the Early Sllurian Carbonates of the Guelph Region; by E.H. Priebe, C.J. Neville and F.R. Brunton. This Groundwater Resources Study—as a digital data release—provides a large, high-quality set of hydraulic conductivity (“K”) estimates, with values tied to stratigraphy, for the Guelph region. The 72 hydraulic conductivity values represent a summary of the best discrete single-hole hydraulic testing conducted for the City of Guelph over the past 2 decades. This study was conducted in collaboration with the City of Guelph. The accompanying report provides detailed descriptions of how the hydraulic test analyses were conducted, a summary table of the best K estimate for each test and the borehole logs for each well. Associated hydraulic test analyses for each hydraulic conductivity value are also provided as graphic plots, which are hyperlinked from the report. Data files are provided as 1 portable document format (.pdf) file, 53 plots (as .tif files) and 1 Microsoft® Excel® 2010 workbook (.xlsx). Available on 1 CD. $20.00.

Miscellaneous Release—Data 353
Graphic Logs with Analytical and Geochronological Data from Hand Auger, Probe and Section Sites in the Niagara Peninsula; by A.K. Burt. This release consists of data from reconnaissance field operations conducted in 2013 for the Niagara Peninsula three-dimensional (3-D) Quaternary geology mapping project. A total of 130 sites were investigated, including 5 surface observation sites, 3 shallow test pits, 24 soil probe sites, 64 hand auger sites and 34 sections. This release provides analytical data (carbonate, grain size, pebble and radiocarbon analyses), field data (glacial feature observations), subsurface data (geological descriptions and interpretations; hydrostratigraphic units), 6 location maps and 75 selected field photographs. These data are summarized visually as graphic logs for each of the 130 sites. The data are available as 9 Microsoft® Excel® (.xlsx) files, 211 image (.tif or .png) files and 1 portable document format (.pdf) file on 1 CD. $20.00.


OGS 2017 Project Areas Are Now Viewable Using OGSEarth

The geoscientists of the Earth Resources and Geoscience Mapping Section of the OGS are out again this summer collecting new geoscientific information right across the province. Descriptions of the 23 active projects and their locations can be viewed using OGSEarth, an OGS application that allows geoscience data to be viewed using the map-based program Google Earth™ mapping service. Also provided for each project is a list of related publications.

If you’re new to OGSEarth, it’s a valuable application for discovering and viewing not only OGS geological data, but also information on mining claims, index maps, administrative boundaries and abandoned mines.
