• OGS

The Ontario Geological Survey (OGS) was formed in 1977 from the Geological Branch and the Mineral Research Branch of the Ontario Ministry of Natural Resources.

The OGS originally consisted of five sections - Precambrian Geology, Geophysics-Geochemistry, Mineral Deposits, Engineering and Terrain Geology, and Geoservices.

In 1992, the various sections of the OGS were reorganized into two branches - the Geoscience Branch and the Information Services Branch. In late 1993 or early 1994, however, this branch structure was dissolved, and the OGS reverted to consisting of a variety of sections. By 1997, the sections of the OGS included the Sedimentary Geoscience Section, the Precambrian Mapping Section, the Office of the Resident Geologist, and the Geoscience Laboratories Section.

The OGS formed a part of the Mineral Resources Group of the Ministry of Natural Resources, from 1977-1985. In 1985, the OGS was transferred to Mines and Minerals Division of the Ministry of Northern Development and Mines.

The Ontario Geological Survey (OGS) provides geoscience information on provincial geology and mineral resources to encourage exploration, provide a basis for land-use planning, and aid development of mineral resource policies. Its activities include: geological, geophysical, and geochemical surveys; mineral deposit studies; geochronology studies; development of new exploration techniques; and presentation of classes and lectures on minerals and rocks.
