Sediment Collected along a Transect from the 

Mojave Desert to the Colorado Plateau

Introduction 

This report presents data and describes the methodology for magnetic, geochemical, and 

textural measurements of sediment and bedrock samples collected along a transect across the 

Southwestern United States (fig. 1). 

The results presented here support a study that examines compositional variations of 

mineral dust deposited during the past few centuries in isolated natural traps spanning a region 

from the Mojave Desert of southern California to the central Colorado Plateau (Goldstein and 

others, in press; fig. 1). In particular, the study addresses the spatial and temporal variations in dust 

composition in the context of landscape geochemistry over a large area of the southwestern United 

States. 

Methods 

Site Selection and Sampling 

The sampling sites were determined on the basis of spatial coverage along the transect and 

occurrences of mature eolian sandstone substrates. The sediments for this study were collected 

from natural depressions (potholes) that weathered into mostly eolian sandstones of Jurassic age 

(table 1). The sampled potholes are topographically isolated, so sediment in them can come from 

only two sources — airborne dust and detritus derived from the immediately surrounding 

catchment of the sandstone surface. The surface area of individual potholes and their catchments 

ranged from about 0.5 to 1.0 m2

 and 50 to 100 m2, respectively. 

Sediment in each pothole was sampled incrementally by depth. Three sediment samples 

from most potholes were collected with a trowel at depths of 0–1 cm, 1–2 cm, and 2–5 cm. Only 

4
two sediment samples, 0–1 cm and 1–2 cm, were collected from site 05U–1. For each sample, 

about 50 grams of fine-grained material was obtained over an area of 0.5–1.0 m2. A sample of the 

bedrock in which the pothole formed was also collected. Pothole elevations were determined from 

30-meter digital elevation models (National Elevation Dataset, http://seamless.usgs.gov). 

Laboratory Analysis 

Samples were analyzed at the USGS Earth Surface Processes soils and magnetics 

laboratories (Denver, Colo.) for hygroscopic moisture factor, calcium carbonate percent, particle 

size, and magnetic properties (table 2). The soil analyses followed the protocols outlined in Singer 

and Janitzky (1986). Geochemical analysis was performed by the U.S. Geological Survey 

Geologic Discipline geochemistry laboratoy (Denver, Colo.). 

Hygroscopic Moisture Factor 

The hygroscopic moisture factor (table 2) is a measure of the moisture content of a sample 

at or near field conditions and is calculated by: 

H = OD/AD, where 

H = hygroscopic moisture factor 

OD = oven-dry sample weight (105°C; 16 hours) 

AD = air-dry sample weight 

Calcium Carbonate Percent 

Calcium carbonate percent (table 2) was measured using a Chittick apparatus (Dreimanis, 

1962) as described by Machette (1986), whereby 6N HCl is applied to the sample and the gas 

evolved from the reaction displaces fluid within the Chittick apparatus. The volume of displaced 

liquid is used to calculate the percentage of calcium carbonate in the sample. 

CaCO3 % = (VCO2 * C)/WS, where 

CaCO3 % = calcium carbonate percent 

VCO2 = The volume of liquid displaced during reaction in presence of HCl 

C = Variable; (PB/TK)*0.16, where 

PB = barometric pressure in Hg mm 

TK = temperature in Kelvin 

WS = oven-dry sample weight (105oC; 16 hours) 

5
Particle-Size Analysis 

Particle-size analysis (PSA) was performed on the <2-mm-size fraction of the pothole 

sediment and on bulk bedrock by using a laser analyzer (tables 2 and 3). Bedrock samples were 

lightly disaggregated to obtain the PSA sample. Prior to analysis, all samples were prepared by 

digesting organic matter and CaCO3 using 30 percent H2O2 and 15 percent HCl, respectively. Also 

prior to analysis, sodium hexametaphosphate was added to each sample to deflocculate clays. 

Magnetic Properties 

Magnetic properties were determined on both <2-mm- and <63-μm-size fractions of the 

pothole samples as well as on bulk bedrock samples (tables 2 and 4). Magnetic properties 

determined included low-frequency and high-frequency magnetic susceptibility (MSlf, MShf), 

anhysteretic remanent magnetization (ARM), and isothermal remanent magnetization (IRM). 

Magnetic Susceptibility 

Magnetic susceptibility (MS) was measured by using a susceptometer with a sensitivity better than 

about 4 × 10–7 m3/kg. Samples were measured in a 0.1-mT (millitesla) induction at a low 

frequency of 600 Hz (MSlf ) and high frequency of 6,000 Hz (MShf). For each sample, the MS 

value was determined as the mean of four measurements. Frequency-dependent susceptibility was 

calculated as: 

FDMS = (MSlf – MShf )/ MSlf. 

Laboratory-Induced Magnetization 

Measurements of anhysteretic remanent magnetization (ARM) and isothermal remanent 

magnetization (IRM) experiments were made by using a high-speed spinner magnetometer. 

Anhysteretic remanent magnetization was imparted in a decreasing alternating field from a peak 

induction of 100 mT and a DC bias of 0.1 mT. IRM magnetizations were generated at room 

temperature by using an impulse magnetizer. First, IRM was imparted in a 1.2-T induction 

(IRM1.2T). The samples then were magnetized in the opposite direction by using an induction of 

0.3 T (IRM-0.3T). Hard isothermal remanent magnetization (HIRM) and the S-parameter were 

calculated as follows (King and Channel, 1991): 

HIRM = (IRM1.2T + IRM-0.3T)/2; 

6
S = IRM-0.3T / IRM1.2T 

Geochemical Analysis 

Samples were analyzed for chemical properties by inductively coupled plasma–atomic 

emission spectrometry (ICP–AES), inductively coupled plasma–mass spectrometry (ICP–MS) and 

X-ray fluorescence (XRF) techniques (tables 2 and 5) (Lichte and others, 1987). Sediment and 

bedrock samples were analyzed on the <63-μm and bulk size fractions, respectively, and were 

finely ground using a shatterbox.

Table 3. Particle size data. 

This table contains high-resolution particle-size data obtained using a laser particle-size analyzer. The particle size is 

displayed in accordance with the Wentworth scale (Wentworth, 1922). Values are reported as volume percent. Each 

value corresponds to the volume percent of the sample that has a grain size falling within that range.

Table 5. Geochemical data. 

This table contains geochemical data obtained by ICP–AES (inductively coupled plasma–atomic emission 

spectrometry), ICP–MS (inductively coupled plasma–mass spectrometry), and XRF (X-ray fluorescence) techniques 

(Litche and others, 1987). All analyses were performed at the USGS Geologic Division geochemistry laboratory in 

Denver, Colorado, and are reported in parts per million (ppm) or percent (%). 

[Sample no., Unique sample number (for example, 44/0-1); presented as site designation (44), and depth in centimeters 

(0-1).
