This dataset exhibits the surficial geology of the Oak Ridges Moraine area, southern Ontario. The study area includes most of the Greater Toronto Area. The surficial geology of the Oak Ridges Moraine is simplified to four principal units. They are, stratigraphically upward: 1) Lower sediment; 2) Newmarket Till; 3) Oak Ridges Moraine and channel sediment; and 4) Halton Till. Lower sediment comprises 10 formations that are stratigraphically beneath Newmarket Till.
The purpose is to show a unified surficial geology of the study area. This dataset is used to realize other themes.
