LEGEND
Sample types (based on laboratory sieve analysis - see Table 1)SampleSymbol Definition
NoteThis is a composite legend for all granular-aggregate resource maps. All aggregate zones and sample types shown in the legendmay not appear on this map. Aggregate zone classification is based on airphoto interpretation, field investigation and sieveanalyses. Areas outside the numbered zones have no known potential for granular materials; however silty tills, rock rubblesuitable for fill, and bedrock suitable for aggregate may be present. Classification criteria used on this map do not considercurrent or conflicting land uses, nor do they guarantee either access to, or the quality of, the material located within these zones.
Multiple samples taken from the same site in different years are listed in order from oldest to youngest. Multiple samples taken atthe same site in the same year are listed in order, from the top of the exposure to bottom.

GRAIN-SIZE ANALYSES
Commonly gravel or sand, having silt-clay content < 5 percent. Deposits are commonly graded and stratified.
Commonly till, poorly graded and of variable grain size, having a silt-clay content (> 5 and < 15 percent) and stonesize exceeding allowable limits for most geotechnical purposes (except subgrade uses) without processing (i.e.,washing, screening or crushing).
Commonly silty till, silt or clay samples, having silt-clay content > 15 percent.

INDEX MAP
Grain-size results from the 63, 32, 16 and 8 mm mesh sieves were obtained at the sample site location by sieving between 10 and 15kg of material. A 500 to 1000 gm split of the <8 mm material (sand-silt-clay) was retained for laboratory sieve analysis. Laboratorysieve analyses included the use of seven sieves with mesh openings of 4, 2, 1, 0.5, 0.25, 0.125, 0.062 and the -0.062 mm panfraction. Samples were wet and/or dry sieved (Kirby et al., 1983) depending on silt-clay content and consolidation of particles.et al.,
ZONES OF AGGREGATE POTENTIAL
Contains granular materials; probability of locating economic deposits is moderate to high
Contains thin (less than 2 m) or discontinuous granular materials; also includes areas where extent of thickerdeposits could not be determined by field investigation; probability of locating economic deposits is moderate to low
May contain granular materials but deposits are not substantiated by field investigation; probability of locatingeconomic deposits is moderate to low
Material of granular composition (e.g., sandy tills and colluvium) that generally contains up to 8 percent silt-claycontent, but could be improved for higher grade uses by washing or screening
Contains sand-size granular materials; high potential for economic exploitation of sand; low to moderate potential forcoarser granular materials
Eskers: sinuous ridges of granular materials; moderate to high potential for economic exploitation
Study Area within the dashed outline
In addition to this map data, a granular-aggregate database is accessible in the Geoscience Resource Atlas of Newfoundlandand Labrador (http://gis.geosurv.gov.nl.ca) for all granular-aggregate maps and sample data. The database providesinformation on more than 13 000 samples collected from 230, 1:50 000-scale-map areas in Newfoundland and Labrador.
This map was originally produced in a series of blueline maps from airphoto interpretation and field work (Environmental GeologySection, 1983). In some map areas additional sample data was collected after the publication date.
The location of roads added to topographic map base are approximate.
