INTRODUCTION

This report contains analytical data for 62 rock samples, and 122 stream-sediment samples collected by the U.S. Geological Survey (USGS), and 57 soil, and 10 stream-sediment samples collected during the National Uranium Resource Evaluation (NURE) program. The NURE samples were re-analyzed for the present study. All samples are from the Chocolate Mountain Aerial Gunnery Range and vicinity, Riverside and Imperial Counties, California. The analyses of these samples can be used for baseline, mineral resource, and environmental geochemical studies.

The location of the Chocolate Mountain Aerial Gunnery Range is shown in figure 1. The Chocolate Mountain Aerial Gunnery Range occupies most of the area of the northwest-trending Chocolate Mountains, and includes a part of the Little Mule Mountains. The Salton Sea and Imperial Valley lie to the west, and the Orocopia and Chuckwalla Mountains are to the north. Elevation ranges from sea level along the west side up to 2,990 ft (911 m) at the highest point. The Salton Sea sheet (Jennings, 1967) of the Geologic Map of California includes the area of the Chocolate Mountains Aerial Gunnery Range. The geologic map of Imperial County (Morton, 1977) includes the part of the gunnery range that is within that county, at a scale of 1:125,000. Brief descriptions of the geology of the Chocolate Mountains are given by Dillon (1986), and by Powell, and others (1994).

This report consists of two parts. Part A is this printed report. Part B is an IBM- compatible digital version of most of Part A on an 1.44 MB diskette. The diskette includes this text in Corel WordPerfect, version 6.1, as well as an ASCII "readme" file, and the complete data for tables 3 through 6 in both "dbf' and "wkl" formats. The "dbf' files are similar to the tables in part A. The "wkl" files are more complete and include the specific limits for elements with more than one lower limit of determination. The wkl file for table 3 also includes the rock descriptions. The four figures are not included in the diskette version.

SAMPLE COLLECTION AND PREPARATION

A total of 62 rock samples were collected from 60 sites. The samples consisted of composited chips from several outcrops, or of a composite of several grab samples from a mine or prospect dump, all of which were collected from within a 30-meter radius of each sample site plotted on figure 2.

Samples of bulk stream sediment were collected from 122 sites. All samples were taken from dry stream beds, and most were from stream beds with gentle to moderate gradients. The bulk stream sediment at each site was composited from several localities extending across what appeared to be the most recently active stream channel. The localities were within a 30-meter radius of each site plotted on figure 3.

Selected soil and stream-sediment samples previously collected for the NURE program study of the Salton Sea 1x2 degree quadrangle were obtained from USGS archives in Denver, CO, for re-analysis. NURE sampling (Heffner, 1980) was done in 1979 in the southern half of the Chocolate Mountain Aerial Gunnery Range, southeast of the proximity of Surveyors Pass,

and along the northern fringes of the gunnery range. NURE sampling methods are described in Price and Jones (1979). Locations of the NURE sample sites are shown on figure 3.

The rock and stream-sediment samples collected during the present study were prepared and analyzed by Enzyme Laboratories, Inc. Enzyme Laboratories (formerly ACTLABS, Inc.) routinely crushed the entire rock sample to minus- 10-mesh (2 mm), mechanically split the rock sample, and pulverized a split to at least minus-150-mesh for analysis. The stream-sediment samples were sieved at the sample site to minus-10-mesh (2 mm) with stainless-steel sieves. These samples were further sieved in the laboratory and the minus-80-mesh (0.189-mm) fraction was retained for analysis and pulverized as described for the rock samples.

The NURE stream-sediment and soil samples had previously been prepared. The samples were sieved to minus- 100-mesh, and pulverized to a fine powder that was also approximately minus 150-mesh. These samples were analyzed by XRAL Laboratories.

ANALYTICAL METHODS

All samples were submitted to the laboratories in a random sequence and generally in groups of 40 samples. Duplicate samples and internal standards were submitted with the samples to check the accuracy and reproducibility of the analyses. Enzyme Laboratories analyzed samples for 29 elements (As, Au, Ba, Br, Ce, Co, Cr, Cs, Eu, Fe, Hf, Hg, Ir, La, Lu, Na, Nd, Rb, Sb, Sc, Se, Sm, Sn, Ta, Tb, Th, U, W, and Yb) by instrumental neutron activation (INAA), and for 19 elements (Ag, Al, Be, Bi, Ca, Cd, Cu, K, Mg, Mn, Mo, Ni, P, Pb, Sr, Ti, V, Y, and Zn) by inductively coupled plasma-atomic emission spectrometry (ICP-AES) after a hot-acid extraction technique. The elements analyzed and lower limits of determination are listed in table 1.

XRAL analyzed samples using two methods of ICP-AES, a partial-extraction method, and a hot-acid extraction method. The methods are similar to those described by Motooka (1990), and by Briggs (1990), respectively. Nine elements (Ag, As, Bi, Cd, Cu, Mo, Pb, Sb, and Zn) were analyzed by the partial-extraction method of ICP-AES, and 37 elements (Ag, Al, Au, Ba, Be, Ca, Cd, Ce, Co, Cr, Cu, Eu, Fe, Ga, Ho, K, La, Li, Mg, Mn, Mo, Na, Nb, Nd, Ni, P, Pb, Sc, Sr, Ta, Th, Ti, U, V, Y, Yb, and Zn) were analyzed by the hot-acid extraction method. The elements analyzed and lower limits of determination are given in table 2.

The results for all elements analyzed by the two laboratiories are listed in tables 3-6 of part A and are included as digital files in part B of this report. Elements with no reported values have been omitted from tables 3-6 included in part A of this report. Thus, of the original 48 elements determined by ACTLABS, three elements determined by INAA (Hg, Ir, and Sn), and one element determined by ICP-AES (Bi), were deleted from the rock data set (table 3), and three elements determined by INAA (Hg, Ir, and Sn), were deleted from the stream-sediment data set (table 4). Of the original 46 elements determined by XRAL, one element determined by the partial extraction method of ICP-AES (Ag), and six elements determined by the hot-acid extraction method of ICP-AES (Ag, Au, Cd, Ho, Ta, and U), were deleted from the stream- sediment and soil data sets presented in tables 5 and 6. One additional element determined by the hot-acid extraction method of ICP-AES (Mo), was also deleted from the soil data set in table 6. Analyses for the remaining elements for each sample type are listed in tables 3-6.

DESCRIPTION OF DATA TABLES FOR PART A

The analyses are listed in tables 3-6. Information on the column headings and sample numbers is given below.

Sample For each sample in tables 3 and 4, the first two letters, CD, identify the current project. For each sample in tables 5 and 6, the first two letters, SS, identify samples originally collected as part of the NURE study of the Salton Sea 1x2 degree quadrangle. For tables 5 and 6 the next two letters identify the 15' quadrangle from which the samples were collected (Heffner, 1980, p. 13). The three digits following letters in all tables give the site number. For tables 5 and 6, the site numbers given are for sites within the 15' quadrangle indicated by the previous two letters. For samples listed in tables 3 and 4, the letters following the site numbers indicate the sample type as follows: "RK" for rock and "SS" for stream sediment. For samples listed in tables 5 and 6, the site numbers are followed by the letter "S"; for these tables the sample type is identified by the title of the table.

In table 3, a sample ID with "RK" followed by an "A", "B", or "C" and with the sample number duplicated, indicates additional samples at the same site.

Latitude and longitude-The next two columns give the latitude and longitude, in degrees, minutes, and seconds, for each sample.

AG PPM, or AL PCT, through ZN PPM--These columns of analyses list the element symbol, whether the concentrations are in parts per million (PPM), parts per billion (PPB), or percent (PCT), and the analytical method. An "ICP" below the element symbol indicates inductively coupled plasma-atomic emission spectrometry (ICP-AES), with total digestion; an "INAA" below the element symbol indicates instrumental neutron activation analysis (tables 3 and 4, ACTLABS analyses); and "ICP-P" indicates a partial-extraction method of ICP-AES was used; an "ICP-T" indicates a hot-acid extraction method of ICP-AES was used.

Rock descriptions~The rock descriptions given in table 3a are field terms based on identification with a hand lens. The list also includes locality comments, where appropriate.

OTHER INFORMATION

More than one lower limit of determination was reported for some of the elements analyzed by ACTLABS. The elements with more than one lower limit are Ag by ICP-AES, and Au, Ba, Ta, and W, by INAA. The "wkl" files in part B of this report show the correct lower limits for each censored value. Although the lower limit of determination is not shown for each qualified analysis in the tables of analyses in this part of the report, most lower limits for these elements are as shown in tables 1 and 2. These differences in lower limits resulted from the use of a smaller than standard sample aliquot for a given analysis because of insufficient available sample material, or from sample matrix differences.

Because of the formatting in the computer programs used to produce the data in the "dbf' and "wkl" files on the diskette, the elements listed in the tables may carry one or more nonsignificant zeros to the right of the significant digits. The analysts did not determine these elements to the accuracy suggested by the extra zeros shown. In general, the elements shown in percentage, are correct to two decimal places (P is correct to three places). For other elements, values to the left of the decimal point generally do not contain more than two or three significant digits.

Sample numbers have been modified for the sample location maps (figures 2-4). The first two letters of the prefix for NURE samples have been removed. For samples collected during the current study ("CD" prefix), the letter suffixes were removed.
