INTRODUCTION

This paper presents sediment magnetic data from Holocene soil and 

parent loess material from the Elba Cut of central Nebraska. These data were 

collected as part of a broader study of the magnetic properties of midcontinent 

soils and loess. The ultimate objective of this study is to better understand the 

types, characteristics, and origins of magnetic minerals in midcontinent soils and 

loess and their possible relations to paleoclimate. The magnetic data presented 

here are part of a larger study by the U.S. Geological Survey of North American 

paleoclimates during the last interglacial period.

The Elba Cut, located about 5 km east of Elba, Nebraska, represents a 

dramatic exposure of Pliocene to Holocene sediments. These sediments were 

exposed in 1991 when the Fullerton Canal was cut through the divide between 

North Loup River and Cedar Creek. The exposure is about 305 m long and 19.8 

m high. A detailed description of the stratigraphy and age relations of sediments 

in the Elba Cut is provided by May and others (1995).

METHODS 

Sampling

Samples were collected in three separate traverses. The first traverse 

provided samples from a modern soil profile developed on the Peoria Loess. 

Samples were collected as representative "channel" samples from each of the 

major soil units (e.g., the A1 horizon, the BK2 horizon, etc.). Each sample was 

collected from material over the depth range of the exposed horizon. Similarly, a 

profile of "bulk" samples was collected from the thick exposure of Pliocene and 

Holocene sediments in the Elba Cut. In this traverse representative samples of 

all major units were collected (e.g., samples of Peoria Loess, Sangamon soils, 

Oilman Canyon soil, etc.). Finally, a detailed collection of samples every 0.05 m 

was obtained from this same thick section.

For the analysis of magnetic properties such as magnetic susceptibility 

and laboratory induced magnetizations, splits of the soil and loess samples were 

packed into plastic cubes that are capable of holding approximately 3.2 cm3 of 

material. Each sample and cube were weighed, and the average weight of an 

empty sample holder was subtracted from the gross weight in order to get the 

true weight of the sample.

Magnetic Susceptibility

A susceptibility meter, operating at a sensitivity better than 10~5 volume SI 

at about 600 Hz or 6000 Hz, was used to measure low-frequency (LFMS) and 

high-frequency (HFMS) magnetic susceptibility of soil and loess samples. In 

addition, useful magnetic parameters, the frequency dependence of magnetic
susceptibility (FDMS) and the percentage of FDMS (%FDMS), were calculated 

using the following formulas:

FDMS = (LFMS-HFMS)

and

%FDMS = [(LFMS-HFMS)/LFMS] * 100. 

Magnetic susceptibility data are listed in Table 1. 

Laboratory Induced Magnetizations

An anhysteretic remanent magnetization was imparted to each sample by 

placing it in a slowly decaying alternating field with a peak field of 100 mT while 

it was subjected to a DC bias of 0.1 mT. The ARM was then measured using a 

high-speed spiriner magnetometer operating at 90 Hz. Following the ARM 

acquisition experiments, an impulse magnetizerwas used to impart isothermal 

remanent magnetizations (IRMs) to each specimen. Each specimen was given 

an initial IRM in an induction of 1.2 T (i.e., IRMi.2-r), and the resultant 

magnetization was measured using the spinner magnetometer. Each sample 

was then given an oppositely directed IRM in an induction of 0.3 T (IRM.0.3-r) and 

the remanence was again measured with the magnetometer. The "hard" 

isothermal remanent magnetization (HIRM) and the S parameter were then 

calculated as:

HIRM = (IRMis + IRM.0. 3)/2,

and S = -IRM.o.3/IRMi2, 

as suggested by King and Channel (1991).

Raw and corrected induced magnetization data and the HIRM and S 

parameters are listed in Table 1 .

Thermomagnetic Determinations

Curie temperatures were determined for magnetic minerals separated 

from several bulk sediment/soil samples. Separation of the magnetic phases was 

made by dispersing the soil or loess sample in distilled water, along with a small 

amount of a surfactant, in an ultrasonic cleaner. The resultant slurry was then 

pumped past a permanent magnet using a technique similar to that described by 

Petersen and others (1986). The resultant magnetic separates were rinsed with 

acetone to remove water and then allowed to dry in air.

Curie temperatures of the soil and loess samples were investigated using 

two different types of thermomagnetic devices. The first consisted of sensitive
electrobalance similar to that described by Larson and others (1975). In this 

device, saturation magnetization in an applied field of 0.2 to 0.45 T was 

measured as a function of temperature. The samples were heated in air up to a 

maximum temperature of about 660°C (approximately 15°C/min) and then 

allowed to cool to near room temperature. Each sample consisted of about 0.15 

to 0.40 mg of magnetic material separated from the magnetic separate using a 

hand magnet. Thermomagnetic curves obtained using the Curie balance are 

given in Figure 1.

The second device used in the thermomagnetic experiments measured 

magnetic susceptibility as a function of temperature. In this device, the magnetic 

separate was placed in dry A^Oa powder and placed in a quartz tube. A platinum 

temperature sensor was then inserted into the tube such that the end of the 

sensor was nearly in contact with the magnetic separate. The sample was then 

heated in a series of steps to a peak temperature of 630 to 660°C and then 

cooled. Magnetic susceptibility was measured approximately every 3°C by 

inserting the furnace assembly into a coil and switching off the furnace current. 

Thermomagnetic experiments were performed both in an atmospheric 

environment and by allowing a low flow (approximately 0.05 liters/min) of argon 

to pass over the sample. The magnetic susceptibility of all samples were 

corrected for the diamagnetic susceptibility of the SiO2 tube and AI203 powder by 

subtracting the average susceptibility of a "blank" sample consisting of a tube 

containing an approximately equivalent amount of A^Oa to that used in each 

experiment.

Experiments at the U.S. Geological Survey sediment magnetism 

laboratory (Denver) have shown that the Curie temperature of individual samples 

determined using this device, held in a constant position from experiment to 

experiment, are reproducible to about 1 to 2°C (assuming no significant phase 

changes during the experiments). The presence of temperature gradients in the 

furnace system and inherent uncertainties in the position of samples in individual 

heating experiments, however, indicates that the uncertainty in the determination 

of Curie temperatures for individual samples is probably on the order of 4 to 5°C 

(one standard deviation). Thermomagnetic curves of magnetic susceptibility vs. 

temperature are shown in Figure 2; analytical data obtained during these 

experiments are listed in Table 2.

Howard County, Nebraska.

Sample No: A unique number assigned to loess and/or sediment samples that 

are placed in approximately 3.2 cm plastic boxes.

Unit: The lithologic unit from which the sample was derived.

Depth (m): The original depth in the section from which the sample was 

obtained. In general, this number represents the midpoint of the interval over 

which the sample was collected.

Com. Depth (m): The depth obtained after combining the Elba Modern soil with 

the other two sampling profiles. Because there is a break in section, the 

composite depth for the loess sections was calculated by arbitrarily adding 1.8 m 

to the true sampling depth for both the detailed section and the "bulk" section.

;

Mass (g): Sample mass after correction for weight of the empty sample box.

LFMS (m3/kg): the low frequency magnetic susceptibility obtained by multiplying 

the LFMS (emu/g) by 411/1000 to obtain units of m3/kg.

HFMS (m3/kg): the high frequency magnetic susceptibility (in m3/kg) obtained by 

multiplying the HFMS (emu/g) by 4IT/1000 to obtain units of m3/kg.

FDMS (m3/kg): Frequency dependent magnetic susceptibility = LFMS-HFMS in 

units of m3/kg.

%FDMS: The percent frequency dependent magnetic susceptibility = [(LFMSHFMS)/LFMS]x 100.

ARM (Am2/kg): the raw moment of the anhysteretic remanent magnetization 

divided by the sample mass to obtain units of Am2/kg.

IRM 1.2T (Am2/kg): the raw moment of the isothermal remanent magnetization 

acquired in an induction of 1.2 T, divided by the sample mass to obtain units of

IRM-0.3T (Am2/kg): the raw moment of the isothermal remanent magnetization 

acquired after first exposing the sample to an induction of 1.2 T, followed by the 

application of an oppositely directed induction of 0.3T. The moment of the IRM 

has been divided by the sample mass to obtain units of Am2/kg.

HIRM: the "hard" isothermal remanent magnetization obtained by the formula: 

(IRMi.2T+ IRM.0.3T)/2, in units of Am2/kg.

Sample No: A unique number assigned to loess and/or sediment samples.

Heating Time (sec): The time in seconds during the progressive heating 

experiment.

Heating Susceptibility (raw): The raw susceptibility value (x 10~6 SI) for the 

sample during the progressive heating experiment.

Heating Susceptibility (corrected): The corrected susceptibility value (x 10~6 

SI) during progressive heating after subtracting out the diamagnetic effects of the 

quartz tube and AI2 C>3 powder.

Cooling Time (sec): The time in seconds during the progressive cooling of the 

sample following the attainment of peak heating temperatures.

Cooling Susceptibility (raw): The raw susceptibility value (x 10"6 SI) for the 

sample during progressive cooling.

Cooling Susceptibility (corrected): The corrected susceptibility value (x 10"6 

SI) during cooling after subtracting out the diamagnetic effects of the quartz tube 

and A^Os powder.
