Abstract:

This data set contains geochemical data from soils and other regoliths collected and analyzed by Hans Shacklette and colleagues beginning in 1958 and continuing until about 1976. Geochemical point-symbol maps were plotted from these data and published as U.S.G.S. Professional Paper 1270 entitled "Element Concentrations in Soils and Other Surficial Materials of the Conterminous United States". The samples were collected at a depth of about 20 cm from sites that, insofar as possible, had surficial materials that were very little altered from their natural condition and that supported native plants. The sample material at most sites could be termed "soil" because it was a mixture of disintegrated rock and organic matter. Some of the sampled deposits, however, were not soils as defined above, but were other regolith types. These included desert sands, sand dunes, some loess deposits, and beach and alluvial deposits that contained little or no visible organic material. The samples were chemically analyzed by a variety of techniques in the U.S. Geological Survey laboratories in Denver, CO.

Purpose:

These data provide an ultra-low-density geochemical baseline for soils and other surficial materials in the conterminous United States. The data set contains 1,323 samples for a sampling density of approximately 1 sample per 6,000 square kilometers. The data set is currently the only national geochemical data set collected and analyzed according to standardized protocols. The data are most appropriately used to provide information on background concentrations of elements in soil. The major drawback with the data set is its extremely low number of samples for the entire conterminous US.

Attribute_Accuracy:

Attribute_Accuracy_Report:

The soil samples were chemically analyzed by a variety of techniques over a period of time from the mid-1960's to the late 1970's. Details of the methods are given in the references listed in USGS Open-File Report 81-197 and USGS Professional Paper 1270.

In summary, the methods used were:

1) Emission spectrography (Myers and others, 1961; Neiman, 1976) for Al, Ba, Be, B, Ca, Ce, Cr, Co, Cu, Ga, Fe, La, Pb, Mg, Mn, Mo, Nd, Ni, Nb, P, K, Sc, Na, Sr, Ti, V, Yb, Y, Zn, and Zr;

2) EDTA titration for Ca;

3) colorimetric methods for P and Zn (Ward and others, 1963);

4) flame photometry for K (Ward and others, 1963);

5) flame atomic absorption (Huffman and Dinnin, 1976) for Hg, Li, Mg, Na, Rb, and Zn;

6) flameless atomic absorption for Hg (Vaughn, 1967);

7) X-ray fluorescence spectrometry (Wahlberg, 1976) for Ca, Ge, Fe, K, Se, Ag, S, and Ti;

8) Combustion (Huffman and Dinnin, 1976) for total carbon; and neutron activation (Millard, 1975, 1976) for U and Th.

The accuracy varies with the analytical methodology and with the concentration of the element being analyzed. A small portion of the database contains qualified data. The types of qualifiers in this data set are:

"N", meaning that the element was not detected at concentrations above the detection limit-this is shown in the data set as, for example, 5.000N meaning that the element was not detected at a concentration of 5 concentration units (ppm or %), the detection limit of the technique.

"L", meaning that the element was detected by the technique, but at a level below the detection limit-this is shown in the data set as, for example, 1.000L meaning that the element was detected by the instrument, but at a level that could not be quantified at or above the detection limit, 1 concentration unit.

"B", meaning that there is no data for that particular element in a given sample-this is shown in the data set as .0000B.

"G", meaning that the element was measured at a concentration greater than the upper determination limit for the technique-this is shown in the data set as, for example, 10.0000G, meaning that the element was measured at a concentration greater than 10 concentration units.

Logical_Consistency_Report:

USGS Open-File Report 81-197 gives analytical values for 46 elements analyzed by a variety of methods. For some elements, the methods of chemical analysis were the same throughout the study, while for others, the methods changed as analytical technology improved. However, all the methods used were specifically designed to give the total contents of the element analyzed. Therefore, the results of earlier analysis should be comparable with results of more recent analyses.

Completeness_Report:

Where chemical data is lacking for a given element in a given sample, ".0000B" is shown as the concentration value. Virtually every element in the data set has some samples in which the element was not analyzed. This may have been a conscious decision on the part of the investigators or it may have been the result of insufficient sample to complete all the analytical procedures. This lack of data is most common for the elements Br, C, Ge, I, Rb, S, Sb, Si, Sn, Th, and U.

Sample locations were determined from USGS topographic maps of various scales. The sites are estimated to be accurate to the nearest minute of latitude and longitude.

Process_Step:

Process_Description:

The data were generated by the analytical laboratories of the USGS over several years, beginning in the early-mid 1960's when data were not stored in digital databases. In about 1980, upon completion of the sampling and analysis, the data were keypunched and stored in the PLUTO database. At about this same time, the data were put into .CIM format. In about 1996, a copy the data in .CIM was converted to .dbf format. In 1998, the data in .dbf format was converted to Microsoft ACCESS format (.mdb) and then to ARC-INFO format.
