After three years of development and seven model iterations, the first regional 3-D geological model of the Paleozoic bedrock of southern Ontario is complete. The model encompasses all 110,000 km^2 of the Western St. Lawrence Lowlands region of southern Ontario, except for Manitoulin Island.

The model is constructed in Leapfrog© Works (Aranz Geo Limited) - an implicit modelling application, with 56 layers representing 70 Paleozoic bedrock formations, the Precambrian basement, and overlying unconsolidated sediments. Layers were constructed using formation depth data from 26,950 petroleum borehole records in the Ontario Petroleum Data System (OPDS), supplemented by hundreds of deep bedrock boreholes compiled by OGS. Formation depth data in the borehole records comprise the primary data input for the 3-D model. Model layers are based on a new lithostratigraphic chart prepared for this project. A new digital bedrock topography surface has also been constructed and is combined with a new digital subcrop geology map that approximate and constrain the subcrop surface of each modelled formation and better align the layers with expert knowledge and mapped geology. Model development was an iterative cycle of interim model construction, expert geological appraisal to identify errors/inconsistencies, followed by QA/QC editing of formation depth data using well records, geophysical logs, drill cuttings and drill core.

This project has generated a robust lithostratigraphic model which is a logical next step in the evolution of regional geological mapping. Practical applications of the model include; hydrogeological modelling of groundwater systems, natural resource extraction (e.g., water, gypsum, salt, gas, oil, aggregate), site selection for nuclear waste disposal, exploitation of geothermal energy, public outreach and education, identification of gaps in data and knowledge, and shortcomings in modeling algorithms. Users must recognize that the model is a data-driven algorithmic representation of the actual bedrock geology subject to future improvement and is not a substitute for detailed geological mapping.

This presentation illustrates how the model can be used to visualize geological features of the bedrock of southern Ontario with a tour of 3D scenes created using free viewer software provided by Leapfrog. Model publication will likely occur in 2019 as simultaneous releases of Open File reports by the GSC and OGS, with subsequent posting on the website of the OGSRL.
