ABSTRACT 

This study reports bulk chemical composition of rocks collected from two exposed, 

measured stratigraphic sections at a phosphate mine in southeastern Idaho. The samples 

constitute a set of channel-sampled intervals across the entire thickness of the Meade Peak 

Phosphatic Shale Member of the Phosphoria Formation at two locations exposed during 

mining. The samples characterize the lower phosphate ore, interlayered middle waste rock, 

upper ore, and upper waste units of the member. The rocks from measured section C lie 

closer to the original, pre-mined ground surface than those of measured section D and, 

hence, are more oxidized and weathered than those of Section D. Section C includes a 

channel sample of the overlying Rex Chert Member, and Section D includes a channel 

sample of the underlying Grandeur dolomite, with both samples taken immediately adjacent 

to the Meade Peak Member.

INTRODUCTION 

Background 

The U.S. Geological Survey (USGS) has studied the Permian Phosphoria 

Formation in southeastern Idaho and the Western U.S. Phosphate Field throughout much 

of the twentieth century. In response to a request by the U.S. Bureau of Land Management 

(BLM), a new series of resource and geoenvironmental studies was initiated by the USGS 

in 1998. Present studies consist of (1) integrated, multidisciplinary research directed toward 

resource and reserve estimations of phosphate in selected 7.5-minute quadrangles; (2) 

elemental residence, mineralogical and petrochemical characteristics; (3) mobilization and 

reaction pathways, transport, and disposition of potentially toxic elements associated with 

the occurrence, development, and use of phosphate; ( 4) geophysical signatures; and (5) 

improving the understanding of depositional origin. To carry out these studies, the USGS 

has formed cooperative research relationships with two Federal agencies, BLM and the U.S. 

Forest Service (USFS), which are responsible for land management and resource 

conservation on public lands; and with five private companies currently leasing or 

developing phosphate resources in southeastern Idaho. The companies are Agrium U.S. 

Inc. (Rasmussen Ridge mine), FMC Corporation (Dry Valley mine), Rhodia Inc. (Wooley 

Valley mine-inactive), J.R. Simplot Company (Smoky Canyon mine), and Solutia Inc. 

(Enoch Valley mine). Because raw data acquired during the project will require time to 

interpret, the data are released in open-file reports for prompt availability to other workers. 

The open-file reports associated with this series of resource and geoenvironmental studies 

are submitted to each of the Federal and industry cooperators for technical review; however, 

the USGS is solely responsible for the data contained in the reports. 

Location and General Geology 

The location of the measured sections is shown in figure 1. The sections lie 

approximately 25 km northeast of Soda Springs, Idaho, in an area of southeastern Idaho 

that has had extensive phosphate mining over the past several decades and currently has 

four active phosphate mines. Service (1966) provides an evaluation of the western 

phosphate industry in Idaho and a brief description of the mining history, ore occurrence, 

and geology. More detailed discussion of the Phosphoria Formation in the Western 

Phosphate Field is given by McKelvey and others (1959). Cressman and Swanson (1964) 

discuss detailed stratigraphy and petrology of these same rock units in nearby southwestern 

Montana. Gulbrandsen and Krier (1980) discuss general aspects of the large and rich 

phosphorus resources in the Phosphoria Formation in the vicinity of the Soda Springs, 

Idaho. Gulbrandsen (1966, 1975, and 1979) summarizes bulk chemical compositional data 

for various lithologies of the phosphatic intervals in the Phosphoria Formation.

Correlation with Measured Sections 

Stratigraphic sections of the Phosphoria Formation were measured and sampled by 

the USGS at the Dry Valley mine in southeastern Idaho. Brief descriptions of the 

stratigraphic sections from which the samples discussed in this report have been taken are 

already published (Tysdal and others, 2000), although no thin section, X-ray, or analytical 

technique other than gamma-ray spectrometry has been used to augment the field 

descriptions of the rock units of that report. This report lists the analytical information for 

rock sequences described from those sections. The two reports are best used together in a 

complementary fashion to obtain both descriptive and analytical information about the rock 

sections. Informal bed names-introduced by Hale (1%7, p. 152) and used generally 

throughout southeastern Idaho-are included in a column of each of the data tables in this 

report and in accompanying figures that graphically display the analytical data. Informal 

bed names used only within a specific mine are not presented here. English units of 

measurement are used throughout this report to facilitate direct correspondence with units in 

the extensive historical literature on the Phosphoria and with current industry usage. 

Thicknesses and interval boundary footages listed here are true thickness of the strata at the 

sample site; these thicknesses are corrected for apparent thickening due to dip of the strata 

at the exposed sections at the mine benches. 

The Phosphoria Formation in the vicinity of the measured sections consists of three 

members, which in ascending order are the Meade Peak Phosphatic Shale, the Rex Chert, 

and the informally named cherty shale (McKelvey and others, 1959; Hale, 1%7; Rioux and 

others, 1 g]5). The measured sections of this report focus on the Meade Peak Phosphatic 

Shale Member. The Meade Peak unconformably overlies the Grandeur Tongue of the 

Permian Park City Formation, and the cherty shale member is overlain by the Triassic 

Dinwoody Formation. 

Both sections were measured at essentially the same geographic position, but section 

wpsC (western phosphate section C) was of rock about 1.50 ft higher in elevation than that 

of section wpsD, and much closer to the land surface that existed just prior to mining. 

Measuring a pair of sections close together, but at different depths below this land surface, 

permits evaluation of important effects of weathering on rock geochemistry. Except for 

upper waste strata of wpsD, the two sections were measured on horizontal surfaces exposed 

by mining equipment. The two sections are of similar thickness, as expected. The upper 

ore zone of section wpsD was not exposed on the floor of the open-pit mine because it was 

mostly covered by talus and waste-pile debris at the base of the pit wall. Waste above the 

upper ore zone of wpsD was measured on the pit wall. 

METHODS 

Field Sampling 

The samples within the measured sections that were obtained for geochemical and 

petrological analysis were taken as channeled samples across the entire thickness of the 

interval, as noted in the data tables. The choice of sampling intervals is intended to 

characterize strata of more or less uniform lithology and of a broad thickness that can be 

handled by typical mine equipment should the results of our analyses suggest that separate 

handling of such zones would be advantageous. Within these broad intervals, we have 

sampled finer-scale strata, sometimes as little as one foot thick, where we have noted a 

lithology different or distinctive from the broad interval as a whole. 

6 
Approximately .SOOg to 1 kg of rock were collected for each sample interval. Rock 

samples were scraped or chiseled in a consistent manner across each interval of uniform 

lithology in order to obtain a representative single sample of the entire interval. The bulk 

samples were shipped to the laboratories of the USGS in Denver, Colorado, for sample 

preparation. 

Rock Sample Preparation 

Rock samples were dried in air at ambient temperature. The coarse-fraction samples 

were disaggregated in a mechanical jaw crusher and a split was then ground in a ceramic 

plate grinder to <100 mesh (<0.15 mm). Splits of the latter material were provided to 

various collaborators and to the contract laboratory for analysis. All splits were obtained 

with a riffle splitter to ensure similarity with the whole sample. A set of splits for all samples 

was archived. Splits of about ~50 g were sent to the contract laboratory where they were 

prepared for analysis. 

Analysis 

Samples were analyzed for 40 major, minor, and trace elements using acid digestion 

in conjunction with inductively coupled plasma-atomic emission spectrometry (ICP-AES). 

For 40-element analysis (referred to as ICP-40), a split was dissolved using a lowtemperature ( <1.SOOC) digestion with concentrated hydrochloric, hydrofluoric, nitric, and 

perchloric acids (Crock and others, 1983). The analytical contractor has modified this 

procedure to shorten the digestion time (P. Lamothe, USGS, oral communication). The 

acidic sample solution was taken to dryness and the residue was dissolved with 1 ml of aqua 

regia and then diluted to 10.0 g with 1% (volume/volume) nitric acid. This technique also 

provides analysis of Bi and Sn. However, an inconsistent bias in the Bi and Sn data exists 

presently for the analytical contractor (P. Lamothe, USGS, oral communication). 

Consequently, the concentration data for these two elements have been eliminated from the 

original analytical data set. Sr concentrations are determined in both the ICP-40 and ICP16 (see below) techniques. However, some detection errors occurred in the data set 

analyzed for Sr by ICP-40 for Section 0. Consequently, that set was eliminated from the 

data files. The ICP-40 technique measures Au above 8 ppm, and Ta above 40 ppm; 

however, no samples from either of the two sections had concentrations above these 

detection limits. Consequently, those data were eliminated from the data files. 

Another split of the sample was fused in lithium metaborate then analyzed by ICPAES after acid dissolution of the fusion mixture. This technique (referred to as ICP-16) 

provides a separate analysis of Si, all other major rock-forming elements, and a few trace 

elements. Most importantly, this is the only analytical technique of those used that 

measures Si in these siliceous, phosphatic shale samples. Although the Meade Peak 

Phosphatic Shale Member is known mostly for its phosphatic content, it also contains 

minor to important amounts of siliceous components, which result from aluminosilicate 

minerals, quartz, or biogenic silica. Si measurement is not possible using the 4-acid 

digestion ICP-40 technique because the Si is lost as a volatile fluoride compound during 

digestion. Analysis of major elements using the fusion technique also provides a 

compositional check on the concentrations of these same elements as measured by acid 

digestion. Ti and Cr were analyzed using both ICP techniques. However, the fusion 

technique is superior to acid digestion for analysis of resistant minerals containing those 

elements. Consequently, the analytical data for these two elements using the ICP-40 

technique have been eliminated from the data set and only those concentration data for the 

fusion technique are reported. The ICP-16 technique also measures Nb above 8 ppm; 

however, no samples from Section 0 had concentrations above these detection limits. 

Consequently, those data were eliminated from the data file. 

7 
Se analysis was petformed using hydride generation followed by atomic absorption 

(AA) spectroscopy. The hydride and AA technique also is used for the analysis of As, Sb, 

and Tl. For the analysis of Se and As, the hydride analytical technique is superior to other 

analytical techniques. Consequently, the analytical data for Se by energy-dispersive x-ray 

fluorescence and for As using acid digestion ICP-AES have been eliminated from the data 

set and only those for the hydride technique are reported. 

Te is measured using AA graphite furnace spectroscopy. TotalS and total Care 

measured using combustion in a LECO furnace followed by gas chromatographic 

measurement. For the other forms of carbon, carbonate carbon is measured as evolved C02 

after acidification of the sample, and organic carbon is calculated as the difference between 

total and carbonate carbon. Crock and Lichte ( 1982) and Jackson and others ( 1988) 

discuss additional analytical methodology. 

X-ray diffraction (XRD) was used to provide a semi-quantitative estimate of apatite 

and other mineral abundance. In the case of phosphate, this estimate is obtained from the 

relative peak heights on the x-ray diffractogram of the 211 lattice-plane diffraction peak of 

the apatite. This technique measures only the phosphate associated with the mineral 

carbonate-fluorapatite, which is the common sedimentary form of apatite in these rocks. In 

theory, the relative peak height is directly proportional to the concentration of the carbonatefluorapatite. This technique provides a minimum estimate of total phosphate because it is 

possible that small amounts of phosphate occur in other forms that are not detected by this 

method. For example, phosphate in organic compounds, amorphous forms, or in minerals 

other than carbonate-fluorapatite would be not be detected using this x-ray analysis. 

Each of the two sections is accompanied by a profile of the equivalent uranium (eU) 

measurements taken with a gamma-ray spectrometer. Concentrations of eU are given in 

parts per million (ppm). Section wpsC was measured with an Exploranium GR-320 and 

section wpsD was measured with a GAD-6 spectrometer. These instruments measure gross 

gamma-ray flux (including cosmic rays) and provide a quantitative measure of K, U, and 

Th. Determination of the abundance of U and Th occurs via detection and counting of 

gamma ra~s of specific energy associated with a particular daughter radionuclide for each 

element, 2 4

Bi with a 1.76 MeV (million electron volt) gamma-ray in the case of uranium. 

Calculation of total abundance of U and Th assumes secular equilibrium between the 

measured daughter nuclide and the parent isotope and all intermediate daughter nuclides for 

each individual element. Potassium abundance is determined from the measurement of 

gamma rays associated with the decar of 40K. The spectrometer integrates detection over a 

23t geometry of approximately 1/2 m and has proportionally higher detection sensitivity to 

those gamma rays that are emitted closer to the detector. The calibration equations for the 

two spectrometers assume this geometry on a planar sutface and are based on analysis of 

concrete pads of known composition of the three elements. The calibration coefficients, as 

well as the constants for subtracted background counts, are a function of latitude, altitude, 

rock density, and moisture. The coefficients become less reliable as location and rock 

conditions change from those of the calibration. 

In Tysdal and others (1999), we plotted eU concentration data after normalization of 

the highest eU concentration of section wpsA, 373 ppm, to 200 ppm and of section wpsB 

from a high of 468 ppm to a scaled high value of 282 ppm. For.the eU data graphed in 

Tysdal and others ( 1999) and tabulated in Herring and others ( 1999) the original eU 

measurement can be extracted from the plotted values by multiplying by scaling factors of 

1.87 for section spsA and 1.66 for section wpsB. This scaling was done because published 

reports from the 1970's and earlier on uranium and eU concentrations in the Meade Peak 

Phosphatic Shale Member state that few uranium concentrations from this member exceed 

200 ppm (see Swanson, 1970, and references therein) and we had little independent check 

on accuracy of the spectrometer data. However, new analytical data as part of our study 

question these past published relationships. 

8 
Recently, we re-analyzed a subset of samples using delayed neutron (DN) analysis, 

which has a precision of better than 3 percent and an accuracy of generally better than 5 

percent (McKown and Millard, 1987). The relationship between the two measurement 

techniques is shown in figure 2 for 70 samples. The DN analysis can be used to assess the 

uranium concentration data in Herring and others (1999), which were obtained using ICP40 measurements with a lower detection limit of 100 ppm. For a common set of 12 samples 

where ICP-AES measurements for uranium concentrations are greater than the detection 

limit of 100 ppm, this technique shows that ICP-40 measurements average 12 percent 

greater than those ofDN and have a relative standard deviation of 12 percent. Given this 

relative credibility in the ICP-40 technique as verified by DN analysis, the frequency of 

uranium concentrations> 100 ppm among the set of all composited stratigraphic samples of 

the Meade Peak Phosphatic Shale Member consequently can be estimated. For 182 

channel samples of sections wpsA, wpsB, wpsC, and wpsD as measured by ICP-40, 18 

percent of the uranium concentrations are> 100 ppm, with 16 percent between 100 and 200 

ppm and 2 percent >200 ppm. These channel samples average over intervals from 1 to 15 

feet of true stratigraphic thickness. Clearly, each channel sample will have some uranium 

concentrations that are indeed higher, perhaps considerably so, than the interval average. 

Consequently, we believe that uranium concentrations in excess of 200 ppm are not as 

scarce as reported by Swanson (1970 and references therein) and that uranium 

concentration measurements from the gamma-ray spectrometers are reasonably correct and 

should be reported as measured rather than scaling them against an assumed upper limit 

value.

Previous studies of the Phosphoria Formation maintain that there is a consistent 

relationship between eU and total uranium contents and between total uranium and 

phosphate contents (McKelvey, 1956). Our measurements indicate considerable scatter in 

9 
both relationships (fig. 2; Herring and others, 1999; Herring, unpub. data). Measured eU 

concentrations, even between adjoining 1 foot intervals of consistent lithologic character, 

often exhibit considerable variability. We expect that this results from: (1) fine-scale 

variability in the concentration of uranium; (2) the effect of the geometry of the dipping 

rocks; or (3) from lack of secular equilibrium. Scatter in the U to P20 5 relationship results 

from uranium removal or addition by syndepositional effects and (or) by post-depositional 

alteration, especially weathering. The uranium is mostly located in the phosphate mineral 

lattice as a substitute for Ca; location of the decay (daughter) products is uncertain. For the 

phosphatic rocks of the Phosphoria Formation, total gamma-ray counts are dominated by 

decay of uranium and its various daughter products. ~0 is generally < 1 percent in the 

phosphorite and <3 percent in the middle waste shale; Th concentrations are generally < 15 

ppm in ore and waste shale (Altschuler and others, 1958; Swanson, 1970; Herring and 

others, 1999; Herring, unpub. data). 

The measurements for eU were obtained on high-resolution, 1-foot (true-thickness) 

spacing across both of the sampled sections. These concentration data are graphed in the 

preliminary report on the stratigraphic descriptions of sections C and D (Tysdal and others, 

2000). The eU concentrations reported for the channel-sampled intervals in the data tables 

are obtained by averaging the 1-foot measurements over the spacing that corresponds to 

each channel-sampled interval. 

RESULTS 

Analytical results of the rock analyses for the more-weathered stratigraphic section 

C and less-weathered section D (wpsC and wpsD) are listed in data tables 1 and 2, 

respectively. The tables include listings of the concentrations of the major rock-forming 

elements as oxides as well as elements. The oxide concentrations are calculated from the 

elemental concentrations using standard stoichiometric conversions. Table 1 also includes 

analytical data for a previously un-analyzed channel sample from section B (wpsB) that 

extends from the upper waste unit into the overlying Rex Chert Member. Interval base and 

top footages are specified relative to the stratigraphic base of the Meade Peak Phosphatic 

Shale Member. This base is defined specifically as the base of the Fish-scale marker 

stratum, a bioclastic phosphorite unit. Measured footage numbers increase upward through 

the sections. The concentration data in tables 1 and 2 are listed as reported by the contract 

laboratory and other collaborators. There has been no statistical manipulation of the data or 

consideration of qualified values. Qualified values of concentration result from detection of 

elements that are present but at concentrations less than their lower detection limits (LDL). 

They are listed in the data table with"<" preceding the LDL. No replacement values for 

these qualified concentrations, typically done with most traditional data summarization and 

analysis (for example, see Cohen, 1959), are included. 

As a measure of analytical accuracy, a phosphatic rock analytical standard 

accompanied the rock samples that were submitted to the contract laboratory. The reported 

analysis and best ongoing average values of this standard is given in table 3. Analyses of 

the standards SARM and SARL that are routinely included as a part of the quality control 

monitoring of the contract laboratory also are included in table 3. Finally, we introduce 

three carefully prepared standards to be used as ongoing monitors of analytical accuracy for 

this project (Wilson and others, in preparation). These standards are finely ground splits of 

composite channel samples of two sections of middle waste rock and one of ore from 

Section B. This section was described by Tysdal and others (1999) and its analytical data 

were reported by Herring and others ( 1999). The preparation and use of these standards 

are intended to provide better analytical quality control for the project, especially because the 

standards have similar mineralogy and composition to the typical rocks being analyzed 

within the project. The first reported set of analyses for these standards is listed in table 3. 

10 
As a measure of analytical precision, the analytical sample set includes 6 replicated 

sample pairs for section C and 9 pairs for section D. These samples are identified in the 

data tables. Table 3 includes a listing of the average relative standard difference and average 

relative standard deviation for each element for all replicated samples that did not have 

qualified data in their concentrations. 

The samples were submitted to the contract laboratory in a randomized sequence. 

This eliminates systematic errors from sources such as, for example, instrumental drift. The 

abbreviations for analytical techniques in the column headings of tables 1, 2, and 3 for 

analytical methodology are defined as follows: 

XRD: X-ray diffraction 

Hydr. AA: hydride generation followed by atomic absorption 

CV AA: cold vapor atomic absorption 

ICP-16: inductively-coupled plasma spectrometry, fusion digestion 

ICP-40: inductively-coupled plasma spectrometry, acid digestion. 

Concentrations of various elements in the channel samples of the two sections are 

graphed in figure 3. The few "less-than" concentrations reported for some of these 

elements have been replaced with their lower detection limits for graphing.
