Introduction 

 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. These studies 

involved many scientific disciplines within the USGS and 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 trace elements 

associated with the occurrence, development, and use of phosphate rock; (4) 

geophysical signatures; and (5) improving the understanding of depositional 

origin. 

 This report presents the diffuse reflectance infrared Fourier transform 

(DRIFT) spectra for samples of phosphatic shale collected from the Enoch Valley 

mine located in the Caribou County, Idaho. These measurements were made to 

characterize the infrared spectral signatures of different rock types within the 

more-weathered and less-weathered sections of the Meade Peak phosphatic 

shale member of the Phosphoria Formation. These sections are described in 

detail by Tysdal and others (1999). 

Infrared (IR) spectra were collected on a Nicolet Magna-IR 760 Fourier 

transform infrared spectrometer (FTIR) equipped with a liquid nitrogen cooled 

mercury cadmium telluride (MCTA) detector, a KBr beam splitter, and a Barnes 

Analytical/Spectra-Tech diffuse reflectance accessory. Diffuse reflectance 

spectra were collected in two overlapping regions of the infrared spectrum, 

including the near-IR region from 10,000 to 2,000 cm-1 and the mid-IR region 

from 5,000 to 500 cm-1. For the near-IR region a white-light source was used; 

and for the mid-IR region, an IR glow-bar source was used. The data were 
collected with a nominal resolution of 2 cm-1; typically 200 interferograms were 

co-added to produce each spectrum. 

Ten samples, five from the more-weathered section A, and five from the 

less-weathered section B, were measured. Samples were selected to represent 

the upper and lower ore zones and the different waste zones (fig. 1). The bulk 

mineralogy of the samples, as determined by XRD analysis, are given in table 1 

(from Knudsen and Gunter, in press). The measured samples were splits of 

samples prepared for mineralogical (Knudsen and others, 2000) and chemical 

(Herring and others, 1999 and 2001) analysis. The samples were measured as 

received. They had been air dried and ground to >100 mesh (<0.15mm). No 

additional preparation was performed. 

Results 

The DRIFT spectra for each sample are given in figures 2 through 11. The 

position of absorption bands observed in the spectra can be used to identify 

minerals present in the samples. The given spectra were corrected for 

atmospheric water and CO2 absorptions by using a silvered mirror background 

reflectance spectra as a reference. Band positions and intensities at band 

minimums, were obtained using the Nicolet peak analysis software (OMNIC, 

1999). No additional spectral processing was performed. On the figures the 

band position of major absorption features are labeled in wave numbers (cm-1). 

Minor absorption features are not labeled on the figures but are given in 

Appendix 1. 

Absorption band intensities are given as percent reflectance, relative to 

the background reference spectra. When collecting the background spectrum off 

the mirror, the aperture of the Magna-IR 760 spectrometer typically is closed to a 

minimum setting. Many of the phosphatic shale samples are black, with very low 

spectral reflectance. To measure the spectra of these dark samples, the 

spectrometer’s aperture was opened to a maximum setting to compensate for the 
samples’ low reflectance. Due to the wide-open aperture, some of the measured 

sample reflectance may exceed the background reflectance, resulting in a 

percent reflectance calculation greater than 100 percent for some parts of the 

measured spectra. 

Ore Zone Samples

Samples wpsa006c and wpsb008c are from the lower ore zone of sections 

A and B, whereas samples wpsb131c and wpsb133c are from the upper ore 

zone of section B. These samples primarily consist of apatite, ranging from 75 to 

88 percent. These ore zone samples have very similar spectral signatures (fig. 

12), regardless of the section (A or B) or ore zone (lower or upper). A 

characteristic absorption band at 966 cm-1 is a fundamental apatite vibrational 

band (Ross, 1974). 

Sample wpsb038c is a carbonate-rich sample from the lower ore zone of 

the less-weathered section B. The wpsb038c spectrum (fig. 8) is significantly 

different than other spectra due to the high percentage of calcite. Characteristic 

calcite absorption bands (White, 1974) are observed at 880, 1,099, 1,409cm-1. 

Other high intensity bands observed at 2,163, 2,336, 2,525, 2,628, 2,898 and 

3,022 cm-1 are not seen in the noncarbonate sample spectra and, therefore, 

probably represent overtone and combination bands of calcite fundamental 

absorption features. 

Waste Zone Samples

Samples wpsa085c, wpsa087c, wpsa131c, and wpsb095c are from the 

middle waste zone. The spectra of these middle waste samples are somewhat 

similar (fig. 13); however, the spectrum of sample wpsb095c varies due to the 

relatively high carbonate content. These middle waste samples also contain 

buddingtonite, an ammonium feldspar, in percentages ranging from ~16 to 53 

percent. Figure 14 shows the characteristic absorption band at ~4,717 cm-1 
produced by the NH4+ ion within the buddingtonite crystal structure (Clark and 

others, 1993). 

Sample wpsa156c is from the upper waste zone of the more-weathered 

section A. The wpsa156c spectrum (fig. 6) is similar to the middle waste spectral 

signatures; however, it lacks the 4,717 cm-1 buddingtonite absorption feature. 

The 4,527cm-1 band is a combination band (OH stretch + OH bend) produced by 

clay minerals. 

Equivalent Interval Samples

Several samples were collected from essentially the same interval, but 

from different sections. Samples wpsa006c and wpsb008c come from the lower 

ore zone of the more-weathered and less-weathered sections, respectively. 

These ore zone samples do have very similar spectra as shown fig. 15. The 

weathering, which differentiates the two sections has not produced significant 

differences in the spectral character of these lower ore zone samples. However, 

subtle differences are present in the higher frequency part of the spectra, 

particularly in the 3,000 to 5,000 cm-1 region. Absorption band position data given 

in Appendix 1 indicate a 4,526 cm-1 clay band in the more-weathered wpsa006c 

spectra but not in the less-weathered wpsbB008c spectra. 

Samples wpsa131c and wpsb131c are from much higher in the section. 

Although these samples are from the same interval, they are located in different 

units. Sample wpsa131c is from the middle waste unit, whereas sample 

wpsb131c is from the D bed of the upper ore zone (Tysdal and others, 1999). 

These samples have significantly different mineral compositions (table 1) 

producing markedly different spectral signatures (fig. 16). 

Summary 

DRIFT spectra were collected to characterize the infrared spectral 

signatures of different rock types within the more-weathered and less-weathered 
sections of the Meade Peak Phosphatic Shale member of the Phosphoria 

Formation. The ore-bearing samples have characteristic spectral signatures 

produced by the high concentration of apatite in the ore zones. No significant 

differences were observed in the spectra of ore samples from the upper and 

lower ore zone samples. Minor spectral differences were observed between ore 

samples from the more- and less-weathered sections, caused by the presence of 

clay minerals in the more-weathered section. Samples from the different waste 

zones have significantly different spectral signatures. The spectral signature of 

carbonate-bearing waste is distinguished easily from that of noncarbonate 

bearing waste by the presence of characteristic calcite absorption bands. Waste 

containing buddingtonite is characterized by an absorption band at ~4,717 cm-1.

APPENDIX 1

 DRIFT absorption band positions (cm-1) and intensities (% reflectance), at

band minimums, obtained by using the Nicolet peak analysis software (OMNIC, 

1999). Absorption band intensities are given as percent reflectance relative to a 

background reference spectra. Many of the phosphatic shale samples have very

low diffuse reflectance. To measure the spectra of these dark samples, the 

spectrometer’s aperture was opened to a maximum setting to compensate for the 

samples low reflectance. Due to the large aperture setting, the measured sample 

reflectance may exceed the background reflectance resulting in a greater than 100 

percent intensity calculation.
