Aggregate Potential Maps

In 1995, the BC Geological Survey initiated a program of aggregate potential mapping in British Columbia in response to the need for data to be utilized in the management of aggregate resources and general land use planning at the regional and local levels.
An aggregate potential map typically outlines areas of aggregate resource potential as polygons on the map and qualitatively ranks the relative potential of the areas. Rankings assigned are Historic (which represent recent and present producing areas), Primary, Secondary, Tertiary (potential hosts to future aggregate deposits) and Unclassified. The parameters used in the derivation of the rankings, including landform type, quantity of sand versus gravel, volume estimate, thickness of deposit, etc., are also detailed on the map. On-site geotechnical evaluation is still required to quantitatively confirm the aggregate potential of any specific target. However, the maps provide a quick "first approximation" for alternative land use by also identifying areas which hold little or no potential for aggregate resources. Ultimately, such maps save those planners, developers and producers involved in aggregate considerable effort and cost by focusing attention on select areas.
In 1995, the BC Geological Survey initiated a pilot study in the Prince George area of central B.C. This has been followed with a larger study in the Okanagan area of southeastern B.C. and, since 1998, studies of the Nanaimo, Sea to Sky, Sunshine Coast and North Coast areas.
