Because speleothems provide a temporal record of geochemical variations in groundwater precipitating calcite, ( (super 234) U)/( (super 238) U) variations in speleothems provide a unique method of investigating water-rock interaction processes over millennium time scales. We present high precision Thermal Ionization Mass Spectrometric (TIMS) U-series analyses of speleothems and drip waters from Fogelpole Cave in southern Illinois. Data from all speleothems from the cave show an inverse correlation between ( (super 234) U)/( (super 238) U) and U concentration, following the pattern observed in groundwaters globally. Within a 65-cm-long stalagmite, concordant (super 234) U- (super 238) U- (super 230) Th and (super 235) U- (super 231) Pa ages for 5 samples indicate accurate chronology from 78.5 ka to 30 ka. Notably, ( (super 234) U)/( (super 238) U) (sub o) which differs from most speleothems by having ( (super 234) U)/( (super 238) U) (sub o) <1, positively correlates with speleothem growth rate. We generalize this to the observation that speleothems globally show ( (super 234) U)/( (super 238) U) (sub o) deviating farther from secular equilibrium at lower growth rates and approaching secular equilibrium at higher grow rates. Based on the Fogelpole observations, we suggest that groundwater ( (super 234) U)/( (super 238) U) is controlled by the U oxidation state, the U concentration of the water and the fluid velocity. A transport model whereby U-series nuclides react and exchange with mineral surfaces can reproduce the observed trend between growth rate and ( (super 234) U)/( (super 238) U) (sub o) . Based on this result, we suggest that ( (super 234) U)/( (super 238) U) (sub o) in speleothems may record changes in hydrologic flux with time and thus could provide a useful proxy for long term records of paleoprecipitation.

The loading was normalized to land use and NO (sub 3) (super -) and herbicide losses were compared to estimated losses in other agricultural areas of the Midwestern USA. Our study area consisted of two large karst springs that drain two adjoining groundwater basins (total area of 37.7 km (super 2) ) in southwestern Illinois' sinkhole plain, USA. The springs and stream that they form were monitored for almost 2 years. Nitrate-nitrogen (NO (sub 3) -N) concentrations at three monitoring sites were almost always above the background concentration (1.9 mg/l). NO (sub 3) -N concentrations at the two springs ranged from 1.08 to 6.08 with a median concentration of 3.61 mg/l. Atrazine and alachlor concentrations ranged from <0.01 to 34 mu g/l and <0.01 to 0.98 mu g/l, respectively, with median concentrations of 0.48 and 0.12 mu g/l, respectively. Approximately 100,000 kg/yr of NO (sub 3) -N, 39 kg/yr of atrazine, and 2.8 kg/yr of alachlor were discharged from the two springs. Slightly more than half of the discharged NO (sub 3) (super -) came from background sources and most of the remainder probably came from fertilizer. This represents a 21-31% loss of fertilizer N from the groundwater basins. The pesticide losses were 3.8-5.8% of the applied atrazine, and 0.05-0.08% of the applied alachlor. The loss of atrazine adsorbed to the suspended solid fraction was about 2 kg/yr, only about 5% of the total mass of atrazine discharged from the springs.

At some point, most of the sediment was flushed from the caves and from about 22,700 to 4000 cal yr B.P., floods deposited a drape of sandy and silty sediment on remnant slackwater successions, cobbly alluvium, and bedrock (especially from 7700 to 4000 cal yr B.P.). Clay mineral analyses of the slackwater cave sediment reveal a provenance of chiefly Petersburg Silt, a smectite- and illite-rich proglacial lacustrine unit present in the overlying Illinois Episode glacial succession. Today, remnants of the ancient subterranean slackwater deposits nearly fill several secondary passages and, in at least two locations, cover a cobble-mantled strath terrace 1.3 to 1.5 m above active stream channels. Slumping and sinkhole formation appear to have been important mechanisms for deposition of the ancient subterranean deposits. Slumping of these surficial deposits and associated vegetation can occur along the flanks of sinkholes (in addition to sinkhole formation) and enter caves; however, the finer organics, some of them comminuted during transport into the caves, become part of the cave alluvium. This finer organic fraction is the modern analog of the humified organic matter disseminated in slackwater sediment dated in this investigation by radiocarbon methods. Twenty-four (super 14) C ages on humified organic matter provide chronologic control. The delta (super 13) C values of the organic matter reflect the proportion of C (sub 4) -type to C (sub 3) -type vegetation growing in and around swallets and sinkholes at the time of redeposition. Drought-tolerant C (sub 4) -type vegetation was more prevalent relative to C (sub 3) -type vegetation from 42,500 to 31,200 cal yr B.P. compared to conditions from 28,800 cal yr B.P. to the present. The delta (super 13) C values are consistent with the results from other investigations of speleothems and organic matter from loessial paleosols.

Sinkhole counts were prepared by hand and compared to those generated from USGS DLG data using ArcView 3.2 and the ArcInfo Workstation component of ArcGIS 8.1 software. The study area for this investigation, chosen for its great density of sinkholes, included the 42 public land survey sections that reside entirely within the Renault Quadrangle in southwestern Illinois. Differences between the sinkhole counts derived from the two methods for the Renault Quadrangle study area were negligible. Although the initial development and refinement of the GIS method required considerably more time than counting sinkholes by hand, the flexibility of the GIS method is expected to provide significant long-term benefits and time savings when mapping larger areas and expanding research efforts.

S. Department of Agriculture; United States AB: Abstract A simple model of spring flow in a karst watershed with numerous sinkholes is presented. The watershed is divided into subwatersheds and runoff volume calculated using the NRCS curve number procedure with corrections for actual antecedent moisture conditions using the 5-day antecedent rainfall volume as a parameter. The peak discharge for each subwatershed is calculated with the TR-55 unit discharge equations with time of concentration corrected for the flow through the epikarst and routed exponentially to the spring, using a calibration coefficient. Total discharge at the spring is calculated by summing attenuated peaks from each subwatershed, using a weighting factor based on the predicted arrival time for each peak flow. The model was calibrated on long-term flow data collected at the spring. The calibrated model was then evaluated on four storms measured subsequent to the calibration. The results were acceptable for all but one storm, but indicate the need for improved runoff volume calculation methods in karst watersheds.

Spectra of the stretching bands of methane and water in the aqueous phase were collected at variable temperatures up to a few degrees above the homogeneisation temperature. The composition of the aqueous phase for temperatures below the homogeneisation temperature was calculated with a computer program, using the model of Duan et al. [Geochim. Cosmochim. Acta 56 (1992) 1451]. Results show the dependency of the estimate of the CH (sub 4) concentration on salinity: at constant CH (sub 4) concentration, the CH (sub 4) /H (sub 2) O area ratio of Raman bands decreases with increasing salinity from 0 to 1.6 m and remains constant up to 3.5 m NaCl. The P-T projection of the isopleth of a natural fluid inclusion is deduced from the homogeneisation temperature, its composition obtained from cryometry (mNaCl eq.) and Raman analysis (mCH (sub 4) ) ratio. This methodology was applied to a sample from the Cave-in-Rock MVT deposit (fluorite-Pb-Zn district, southern Illinois, USA) presenting petroleum fluid inclusions associated with fluid inclusions of the system H (sub 2) O-NaCl-CH (sub 4) . Hydrocarbon isochore intersects the isopleth of the H (sub 2) O-NaCl-CH (sub 4) inclusions at the homogenization temperature, which validates this procedure.

The groundwater in this aquifer is an important source of potable water for about half of the residents of the sinkhole plain area. Previous work has shown that groundwater from approximately 18% of the wells in the sinkhole plain has NO (sub 3) (super -) concentrations in excess of the USEPA's drinking water standard of 10 mg N/l. Relative to background levels, the NO (sub 3) (super -) concentrations in water from 52% of the wells, and probably all of the springs in the study area, are anomalously high, suggesting that sources other than naturally occurring soil organic matter have contributed additional NO (sub 3) (super -) to groundwater in the shallow karst aquifer. This information, and the dominance of agriculture in the study area, suggest that agrichemical contributions may be significant. To test this hypothesis, water samples from 10 relatively large karst springs were collected during four different seasons and analyzed for inorganic constituents, dissolved organic carbon, atrazine, and delta (super 15) N and delta (super 18) O of the NO (sub 3) (super -) ions. The isotopic data were most definitive and suggested that the sources of NO (sub 3) (super -) in spring water are dominated by N-fertilizer with some possible influence of atmospheric NO (sub 3) (super -) and, to a much lesser extent, human and/or animal waste. Differences in the isotopic composition of NO (sub 3) (super -) and some of the chemical characteristics were observed during the four consecutive seasons in which spring water samples were collected. Isotopic values for delta (super 15) N and delta (super 18) O of the NO (sub 3) (super -) ranged from 3.2 per mil to 19.1 per mil and from 7.2 per mil to 18.7 per mil, respectively. The trend of delta (super 15) N and delta (super 18) O data for NO (sub 3) (super -) also indicated that a significant degree of denitrification is occurring in the shallow karst hydrologic system (within the soil zone, the epikarst and the shallow karst aquifer) prior to discharging to springs.

This change correlates with increased development and the increased use of aeration systems for private sewage treatment and disposal. The Mississippi Karst Resource Planning Committee was formed by concerned citizens to address the problem. The committee is now engaged in both education and research in the sinkhole plain. Some of these activities are supported by a US EPA Section 319 Grant. The data generated and conclusions drawn should allow for improvement of ground water quality in the region through education and, possibly, regulation on the state or local level. Some local karst regulations have been adopted, in part, due to the efforts of the committee.

Compositional changes are compared to the paragenetic sequence. The fluid inclusions in the early ore minerals are nearly saturated sodium-calcium chloride brines. Fluid inclusions in late minerals are less concentrated and have a lower relative deuterium concentration. In the Cave-in-Rock district the composition of primary fluid inclusions in yellow fluorite, the earliest ore mineral, is similar to that of connate water in the Illinois basin in the same strata as the ore deposits. The change in composition of fluid inclusions in the later quartz and sulfide minerals indicates a water of different origin, possibly magmatic, was introduced. Connate and possible magmatic waters were largely flushed out during deposition of the gangue minerals in the last stages of mineralization, and the composition of the fluid inclusions in these gangue minerals trends toward that of meteoric water or a dilute mixture of meteoric and magmatic water. In the Wisconsin-Illinois-Iowa district, fluid inclusions in the ore minerals are highly concentrated sodium-calcium chloride brines that have a high relative deuterium concentration; inclusion fluid in late gangue minerals contains less deuterium and is relatively dilute.

The stratigraphy of the ore-bearing horizons is described with emphasis on the chemical and physical characteristics of the formations. The contact relationship between the host formation and the blanketing formation is discussed in detail because of its apparent role in the movement of solutions. The structure is defined in 3 categories on the basis of inducing forces or elements. The mineralogy and paragenesis discussions stress the occurrence and the depositional characteristics of the minerals. These factors permit the statement of a new theory of origin of the textural features of the ores. Two breccia pipes are described and are designated as the points at which mineralizing solutions rose from a deep source. The distribution of ore about these breccia pipes indicates that the solutions moved by simple hydraulic principles and provide a basis for the study of solution movement.

Inclusions were studied in minerals of both principal stages of deposition indicated in the deposits. The data obtained indicate that ore deposition took place in the temperature range of 94 degrees C. to 142 degrees C., assuming a pressure correction of +13 degrees C., and that temperature oscillated during mineralization. Fluorite, the first mineral to be deposited in each stage, was deposited in the upper part of the temperature range, and sphalerite and quartz, which followed fluorite in each stage, were deposited at lower temperatures. Petroleum inclusions in fluorite show considerably lower temperatures of vapor bubble disappearance than aqueous inclusions, but petroleum inclusions cannot be used for temperature determinations, because pressure corrections cannot be estimated. The basic assumptions of the method are evaluated with respect to the deposits and it is concluded that no errors of first order magnitude are expected. The apparent variation in temperature during mineralization is tentatively interpreted as the result of 2 pulsations of hydrothermal solutions from a single source.
