About our Data

Report No., or Map No., or Digital Data No.: publication number of the report, map or digital data. The prefix of the publication number indicates the publication series. If a report or map has been revised, both the original publication and the revised version are listed (e.g. P3349 and P3349-REV). For revisions of digital data, only the most recent version is listed in the index (e.g. MRD 229—Revised (MRD229-REV), GDS 1210—Revision 1 (GDS1210-REV1)).

Publication Series explanations are provided below the table.

Report Series

Aggregate Resources Inventory Papers (ARIP): this series reports on the nature and extent of aggregate re- sources within specific areas. The reports include maps illustrating areas of potential for aggregate extraction.

Annual Statistical Reports (ASR): this series contains reviews of mineral production in Ontario. Most publications in this series were issued from 1970 to 1978.

Geoscience Data Inventory Folios (including Geological Data Inventory Folios) (GDIF): this series, initiated in 1982, summarizes all exploration data for specific townships or National Topographic System (NTS) areas. Each folio consists of tabulated data and one or more maps. The series replaces the “Data Series” maps that were released within the Preliminary (P) Map series. The most recent folio was issued in 1994.

Industrial Mineral Background Papers (IMBP): this series covers subjects related to the inventory, development, marketing and use of industrial minerals. The most recent paper was issued in 1994.

Mineral Deposits Circulars (including Mineral Resources Circulars) (MDC): this series covers inventories and geological studies of specific types of mineral deposits, commodities or resources, mainly on an Ontario-wide or regional basis. The most recent circular was issued in 2000.

Miscellaneous Papers (MP): this series, first issued in 1960, provides information on a variety of geoscience topics. Annual compendia, such as the Summary of Field Work and Other Activities and Resident Geologist Program Report of Activities, were published in this series from 1967 to 1998. The reports are rarely accompanied by maps.

Open File Reports (OFR): this series provides the means for rapid release of information soon after project completion. Annual compendia, such as the Summary of Field Work and Other Activities and the Resident Geologist Program Report of Activities, have been published in the OFR series since 1999.

Reports (including Geological Reports, Geoscience Reports) (R): Reports generally cover the detailed geology of specific areas, always include a coloured map, and are based on the results of 1 to 3 years of field investigation. The series, started in 1960, continues the theme of the former Annual Report series. These reports have been published infrequently since 1997.

Special Volumes (SV): Special Volumes are comprehensive compilations of major topics of broad interest to the geoscience community. The series started in 1984. The largest compilation in this series was Geology of Ontario, issued to commemorate the centennial of the founding in 1891 of the Ontario Bureau of Mines.

Studies (including Geoscience Studies, Geological Circulars) (S): this series reports on new information or concepts of scientific merit not covered by other series. The content varies, but mainly covers larger areas than are covered by the report series or discusses a specific subject.

Annual Reports: this series reported on all investigations of the Ontario Bureau of Mines and Ontario Department of Mines from 1891 to 1960. From 1961 to 1972, the annual reports contained statistical reviews of mining in Ontario. The last report in this series was published in 1972.

Bulletins: most of the 173 bulletins deal with mining accidents and annual mineral production. Approximately 20 of the early bulletins cover geological or miscellaneous topics.

Educational Series: this series of nontechnical booklets, which cover topics of interest to explorationists, was begun in 1991. There are only 2 reports in the series.

General Index to Reports Volumes: this series provides a general subject index to all publications of the Mines and Minerals Division and its predecessors. Last issued in 1984, the 9 volumes cover publications from 1891 to 1980.

Geophysical Reports: these reports contain the results of geophysical investigations of specific areas. There are only 2 reports, issued in 1973–1974.

Guidebooks (including Geological Guidebooks): guidebooks are informative and colourful guides to the geology, physiography and scenery of specific areas of the province.

Industrial Mineral Reports: this series presents the results of investigations of the geology and uses of industrial minerals. The series was issued during the period 1953–1975.

Information Circulars: this series of leaflets was begun in 1991 to provide general information about mineral commodities in Ontario.

Mineral Policy Background Papers: this series covers a variety of subjects, each related to the background information needed by government agencies and companies to make in-depth economic decisions on metallic mineral matters.

Nonserial Publications: approximately 150 nonserial publications are available. Most of these are information brochures or booklets, but some are technical reports.

Northern Ontario Engineering Geology Terrain Studies: these reports include detailed descriptions of engineering geology and terrain studies of a specific area. Each report is accompanied by 1 or 2 coloured maps. The series was issued during the period 1979–1983.

Occasional Papers: this series covers a wide variety of mineral-related subjects. The most recent report in this series was issued in 1981.

Oil and Gas Papers (including Papers): this series reports annually on the exploration, drilling and production of oil and gas in Ontario.

Preliminary Reports: this series was issued from 1928 to 1966 and presented preliminary results of geological investigations. The series was replaced by the MP and OFR series.

Video Census Series: this series was used to release annually a statistical computer analysis of the mining industry of Ontario including exploration and development work, and production.

Map Series

Maps (M2), 2000 Series: this series of coloured geological maps presents the final results of the geological investigation of specific areas. Most are accompanied by a final published report, generally in the Report series but occasionally also in the Open File Report, Studies or Mineral Deposit Circular series. This map series replaced the 1900 series.

Maps (M6), 60 000 Series: this series of geophysical and geochemical maps has been produced since 2001. This map series provides a means of releasing data purchased by the Ontario Geological Survey.

Maps (M8), 80 000 Series: this series of geophysical and geochemical maps has been produced since 1979.

Maps, Open File Map (OFM) Series: this series was started in 1985 with the purpose of providing a means for rapid release of information. The last map in this series was issued in 1994.

Maps, Preliminary (P) Series: these maps show the preliminary results obtained for each of the areas studied. The series started in 1956 to provide a means for rapid release of information after each field season and, until 1997, featured uncoloured maps with descriptive notes. Since 1997, preliminary maps, providing information after one or more field seasons, have been produced in colour, generally without descriptive notes.

Maps, 1900 Series: first issued in 1931, these maps show information on a provincial or regional scale. Later, the 1900 series included all geological maps and replaced the “AR” series of maps, which accompanied Annual Reports. This series was discontinued and replaced by the 2000 series in 1960.

Maps, 5000 Series: this series of coloured, engineering geology maps usually accompany Northern Ontario Engineering Geology Terrain Studies (NOEGTS) reports. There are also similar Southern Ontario Engineering Geology Terrain Studies (SOEGTS) maps published; however, the reports to accompany these latter maps were never published. The most recent map in the 5000 series was published in 1990.

Maps, A Series: this series of maps, recording magnetic surveys by Ontario Department of Mines, was issued during the period 1950–1959.

Maps, Annual Report Series: this series, accompanying the Annual Reports of the Ontario Bureau of Mines and Ontario Department of Mines, was issued during the period 1891–1944. The maps cover all geological investigations during that time, but the majority show the results of geologic surveys of specific areas. In 1931, the series was discontinued and replaced by the 1900 series.

Maps, G Series: this series of aeromagnetic maps of Canada provides coverage of standard quadrangles of the National Topographic System (NTS). Within Ontario, these maps are funded and produced jointly or individually by the governments of Canada, Manitoba and Ontario. A complete listing of these maps is given in Index to Maps, Geophysical Surveys, 1950–1991.

Maps, S Series: these maps show surficial geology and were produced by the Ontario Department of Lands and Forests in 1965. There are only 4 maps in this series.

Digital Data Series

Earth Resources and Land Information System (ERLIS) Data Sets (EDS): this series, initiated in 1993, presents the results of the Geology of Ontario Provincial Mapping Project in vector format. The publications of this series provide access to the provincial bedrock geology, Quaternary geology and tectonic assemblage compilations, as well as the Ontario Drill Hole Database. Updates to provincial ground and aeromagnetic data publications, originally released in this series, have been re-released under the Geophysical Data Set series (see below).

Geophysical Data Sets (GDS): this series provides the digital data from geophysical surveys in Ontario and usually accompanies 60 000 or 80 000 series maps. The data are available normally in ASCII and Geosoft® formats, and occasionally in native format. This series was introduced in 2000.

Groundwater Resources Studies (GRS): the Groundwater Resources Study series, first published in 2006, has the objective of providing information on groundwater-related themes, including local- to watershed-scale aquifer characterization and delineation; geologic controls and influences on groundwater quantity and quality; and methods development. The series typically consists of digital reports accompanied by full-colour digital maps and figures.

Mineral Deposit Inventory (MDI): this publication is not a series, but is a stand-alone inventory, in database format, of mineral deposits in the province of Ontario. Originally compiled in the early 1970s by the Resident Geologist Program (RGP) staff, the database is continually reviewed and updated by the RGP staff.

Miscellaneous Release—Data (MRD): this series is an avenue for releasing large amounts of information in digital form, rather than as inclusion as an appendix in a hard-copy report, and allows clients to perform their own data analysis. Some examples of information published in this series are geochemical data, drill hole data and geochronology data; field photographs; and geographic information system (GIS) map compilations.
