• 59, Soil sample sieved to less than 149 microns (-100 mesh)
• 61, Stream-sediment sample from dry stream, sieved to less than 149 microns (-100 mesh) and dried (if necessary) at less than or equal to 110 °C
• 62, Talus sample
• 64, Playa sediment sample
• 66, Stream-sediment sample from flowing stream; sample treatment is most probably as follows: sieved to greater than 149 microns (+100 mesh) but less than 1,000 microns (-18 mesh), and dried at less than or equal to 110 °C
• 70, Wet sediment sample dried at 110 °C; probably prepared from bulk and sieved to -80 mesh
• 72, Dry sediment sample dried at 110 °C; probably prepared from bulk and sieved to -80 mesh

LONGITUDE

Longitude, in decimal degrees, of the sample site. Negative numbers indicate west longitudes. These values are assumed to be based upon the NAD27 Datum and Clarke 1866 Ellipsoid. Sample-site locations recorded by ORGDP commonly give values with 3 decimal places instead of the more common usage of 4 decimal places; therefore, the possible error of location is ±183 feet or ±55 meters.

LATITUDE

Latitude, in decimal degrees, of the sample site. Positive numbers indicate north latitudes. These values are assumed to be based upon the NAD27 Datum and Clarke 1866 Ellipsoid. Sample-site locations recorded by ORGDP commonly give values with 3 decimal places instead of the more common usage of 4 decimal places; therefore, the possible error of location is ±183 feet or ±55 meters.
