Surficial geology deals with loosely consolidated rock materials found at the earth’s surface. Surficial maps and reports include data about the physical and chemical composition of soil, glacial till, sand and gravel, and weathered bedrock.
Under its Surficial Mapping Program, the Geological Surveys Branch:
- produces 1:50 000-scale maps showing the distribution of surficial materials and landforms in New Brunswick;
- conducts geochemical surveys of till, soil, stream sediment, water, humus and vegetation;
- locates and investigates sand and gravel deposits; and
- provides government and the private sector with data and advice applicable to hydrogeological studies, environmental assessment, land use planning, and other aspects of landscape management.
Each year the Geological Surveys Branch initiates geoscientific field projects to serve as a basis for mineral and petroleum exploration and for land-use planning in New Brunswick. Field projects are conducted under our Bedrock Mapping, Surficial Mapping, Metallic Mineral Deposits, Industrial Minerals, Hydrocarbon Resources,Geochemistry and Coastal Mapping programs.
