This aggregate potential map is based on a compilation of published bedrock geology maps and the technical data collected for Economic Geology Series ME 2001-1, Overview of Bedrock Aggregate Potential in the Halifax-Dartmouth Metropolitan Area, Nova Scotia, by G. Prime. Only those rock types capable of producing high quality stone products are identified as having resource potential.
The bedrock aggregate resource potential for the Metro area consists of quartzite and granitic rocks which have been divided into three generalized lithological/textural categories. They are not ranked in terms of aggregate quality on the map because of the geological complexity of the region and the variability in characteristics that can be expected within any grouping. The findings of this study indicate that the bedrock aggregate potential within a category can vary from good to unacceptable for construction aggregate, depending on the geotechnical properties of the stone at any given location.

The data is in six-degree Universal Transverse Mercator (UTM) projection, Zone 20, Central Meridian 63° 00' West using the North American Datum of 1927 (NAD27).
The data files have been compressed using PKZIP into a single, self-extracting EXE file.
The EXE file can also be opened in WinZip to view and extract the compressed files in the data set.
On UNIX platforms, the unzip command will extract the compressed files in the EXE.
All data sets are in six-degree Universal Transverse Mercator (UTM) Zone 20 projection using the NAD27 datum. A readme file and a copy of the licence agreement are also included with each data set.
