Accuracy is estimated to be ∓ 20% for those elements making up more than 0.1 wt.% of the particles and ∓ 50% for elements making up less than 0.1 wt.%. Using IMMA data, we found statistically significant differences between the two samples for five (Fe, Ca, Mn, Li, Ce) of the 25 elements detected. For Li and Mn the differences between the mineral-rich particles within samples were similar to differences found between samples on a whole-coal basis. For Ca and Fe, the differences are attributed to different modes of occurrence, and for Ce, the differences are probably due to an irregular distribution of an inorganic phase. We conclude that the IMMA can be used to obtain semi-quantitative data that may provide insight into the distribution and mode of occurrence of some of the elements in coal.</p></div></div></div></div><div id=\"preview-section-introduction\"><br></div><div id=\"preview-section-snippets\"><br></div><div id=\"preview-section-references\"><br></div>","language":"English","publisher":"Elsevier","doi":"10.1016/0166-5162(84)90021-1","issn":"01665162","usgsCitation":"Finkelman, R.B., Simons, D., Dulong, F., and Steel, E., 1984, Semi-quantitative ion microprobe mass analyses of mineral-rich particles from the upper freeport coal: International Journal of Coal Geology, v. 3, no. 3, p. 279-289, https://doi.org/10.1016/0166-5162(84)90021-1.","productDescription":"11 p.","startPage":"279","endPage":"289","numberOfPages":"11","costCenters":[],"links":[{"id":220631,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"3","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8d08e4b08c986b318234","contributors":{"authors":[{"text":"Finkelman, R.

The study showed that rates of carbonaceous decay were low (kr = 0.03-0.06/day) and that point-source loadings of carbonaceous biochemical oxygen demand (BOD) accounted for less than one-third of the satisfied oxygen demand. Nitrification of industrially discharged ammonia was the dominant cause of DO depletion. The study led to the calibration and verification of a steady-state DO model which was used to examine selected scenarios of BOD loading, ammonia loading, and flow augmentation. In 1976, the modeling projections for the Willamette River were presented to resource managers. A review in 1981 indicated that the State of Oregon had instituted an effluent standard on the major discharger of ammonia, rescinded an order for all municipal wastewaters to receive advanced secondary treatment by 1980, and more fully acknowledged the need for flow augmentation during summer to attain the DO standards.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of the Water Pollution Control Federation","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"JSTOR","issn":"00431303","usgsCitation":"Rickert, D.A., 1984, Use of dissolved oxygen modeling results in the management of river quality: Journal of the Water Pollution Control Federation, v. 56, no. 1, p. 94-101.","startPage":"94","endPage":"101","numberOfPages":"8","costCenters":[],"links":[{"id":219905,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":269368,"type":{"id":11,"text":"Document"},"url":"https://www.jstor.org/stable/25042162"}],"volume":"56","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bbee8e4b08c986b32985e","contributors":{"authors":[{"text":"Rickert, D.

The absence of significant 238U loss in the samples emphasises the reducing conditions at the sampled depths. ?? 1984.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"LITHOS","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/0024-4937(84)90021-5","issn":"00244937","usgsCitation":"Smellie, J.A., and Rosholt, J., 1984, Radioactive disequilibria in mineralised fracture samples from two uranium occurrences in northern Sweden: LITHOS, v. 17, no.

First, the relation between the sum of seismic moments of tremors and the volume of stope closure caused by mining during a given period can be used in conjunction with magnitude-frequency statistics and an empirical relation between moment and magnitude to estimate the maximum possible sized tremor for a given mining situation. Second, it is shown that the 'energy release rate,' a commonly-used parameter for predicting underground seismic hazard, may be misleading in that the importance of overburden stress, or depth, is overstated. Third, results involving the relation between peak velocity and magnitude, magnitude-frequency statistics, and the maximum possible magnitude are applied to the problem of estimating the frequency at which design limits of certain underground support equipment are likely to be exceeded.","conferenceTitle":"Rockbursts and Seismicity in Mines.","conferenceLocation":"Johannesburg, S Afr","language":"English","publisher":"South African Inst of Mining and Metallurgy","publisherLocation":"Johannesburg, S Afr","isbn":"062006708X","usgsCitation":"McGarr, A., 1984, SOME APPLICATIONS OF SEISMIC SOURCE MECHANISM STUDIES TO ASSESSING UNDERGROUND HAZARD., Rockbursts and Seismicity in Mines., Johannesburg, S Afr, p. 199-208.","startPage":"199","endPage":"208","numberOfPages":"10","costCenters":[],"links":[{"id":220099,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505aaf6ee4b0c8380cd875a6","contributors":{"editors":[{"text":"Gay N.C.Wainwright E.H.","contributorId":128366,"corporation":true,"usgs":false,"organization":"Gay N.C.Wainwright E.H.","id":536276,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"McGarr, Art 0000-0001-9769-4093","orcid":"https://orcid.org/0000-0001-9769-4093","contributorId":43491,"corporation":false,"usgs":true,"family":"McGarr","given":"Art","affiliations":[],"preferred":false,"id":366318,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Measurements are commonly censored if they fall below a level associated with some minimum acceptable level of reliability (detection limit). Trace-level organic data were simulated with best- and worst-case estimates of measurement uncertainty, various concentrations and degrees of linear trend, and different censoring rules. The resulting classes of data were subjected to a nonparametric statistical test for trend. For all classes of data evaluated, trends were most effectively detected in uncensored data as compared to censored data even when the data censored were highly unreliable. Thus, censoring data at any concentration level may eliminate valuable information. Whether or not valuable information for trend analysis is, in fact, eliminated by censoring of actual rather than simulated data depends on whether the analytical process is in statistical control and bias is predictable for a particular type of chemical analyses.","language":"English","publisher":"ACS Publications","doi":"10.1021/es00125a009","issn":"0013936X","usgsCitation":"Gilliom, R.J., Hirsch, R., and Gilroy, E., 1984, Effect of censoring trace-level water-quality data on trend-detection capability: Environmental Science & Technology, v. 18, no. 7, p. 530-535, https://doi.org/10.1021/es00125a009.","productDescription":"6 p.","startPage":"530","endPage":"535","costCenters":[],"links":[{"id":220642,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"18","issue":"7","noUsgsAuthors":false,"publicationDate":"2002-05-01","publicationStatus":"PW","scienceBaseUri":"505a05c8e4b0c8380cd50f60","contributors":{"authors":[{"text":"Gilliom, R.

The shale rock appears to have formed in a restrictive marine environment which provided opportunity for the accumulation of marine organic matter to form sufficient kerogen. The shale contains approximately 18% to 22% organic matter which is primarily kerogen. The kerogen has a relatively high H:C ratio indicative of an alginite and/or exinite source (Type 1 and Type II kerogen) and a high proportion of alkane and saturated ring hydrocarbons. However, a few samples have low H:C ratio values and are interpreted to have been formed in a shallow water oxidizing environment. Also, there is a possibility that these low H:C values may represent mixtures of terrestrial and marine organic material suggesting lateral facies changes of the rock from marine to near shore depositional environments. Trace metal values for both the whole rock and the shale oil fraction indicate a generally high V:Ni ratio, also indicative of a marine environment. Other trace metal values are in good agreement with data from other Devonian shales. Throughout the north Alabama and south-central Tennessee study area, the average oil yield from the shale is 13.9 gallon per ton. The highest oil yield values were obtained from the middle and upper parts of the shale sequence.

This advance assures a prominent future position for the use of these techniques in geochemical exploration for concealed mineral deposits. Partial dissolution techniques are classified as single dissolution or sequential multiple dissolution depending on the number of steps taken in the procedure, or as “nonselective” extraction and as “selective” extraction in terms of the relative specificity of the extraction. The choice of dissolution techniques for use in geochemical exploration is dictated by the geology of the area, the type and degree of weathering, and the expected chemical forms of the ore and of the pathfinding elements. Case histories have illustrated many instances where partial dissolution techniques exhibit advantages over conventional methods of chemical analysis used in geochemical exploration.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/0375-6742(84)90078-5","issn":"03756742","usgsCitation":"Chao, T.T., 1984, Use of partial dissolution techniques in geochemical exploration: Journal of Geochemical Exploration, v. 20, no. 2, p. 101-135, https://doi.org/10.1016/0375-6742(84)90078-5.","productDescription":"35 p.","startPage":"101","endPage":"135","numberOfPages":"35","costCenters":[],"links":[{"id":220414,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"20","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bbf53e4b08c986b329abe","contributors":{"authors":[{"text":"Chao, T.

The work was concentrated in the Fort Union, Powder River, and Green River coal resource regions where measures of extractable metals in soils were found to have limited use in predicting metal levels in plants. Correlations between Cu, Fe, and Zn in plants and extractable (DTPA, EDTA, and oxalate) or total levels in native A- and C-horizons of soil were occasionally significant. A simple linear model is generally not adequate, however, in estimating element uptake by plants. Prediction capabilities were improved when a number of soil chemical and physical parameters were included as independent variables in a stepwise linear multiple regression analysis; however, never more than 54% of the total variability in the data was explained by the equations for these metals. Soil pH was the most important variable relating soil chemistry to plant chemistry. This relation was always positive and apparently a response to soil levels of metal carbonates and not Fe and Mn oxides. Studies that compared the metal uptake by rehabilitation species to extractable (DTPA) metal levels in mice soils produced similar results. ?? 1984 Science and Technology Letters.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Minerals and the Environment","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisherLocation":"Kluwer Academic Publishers","doi":"10.1007/BF02043989","issn":"01427245","usgsCitation":"Gough, L.P., 1984, Regional investigations of soil and overburden analysis and plant uptake of metals: Minerals and the Environment, v. 6, no. 3, p. 105-110, https://doi.org/10.1007/BF02043989.","startPage":"105","endPage":"110","numberOfPages":"6","costCenters":[],"links":[{"id":204982,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF02043989"},{"id":219875,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"6","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50e4a534e4b0e8fec6cdbd7f","contributors":{"authors":[{"text":"Gough, L.

R. Doell and G. B. Dalrymple in 1973. We have determined geomagnetic paleointensities by the Thelliers' method for 14 lavas from the three sites. During these experiments, considerable difficulty was encountered because of the presence of titanomaghemite in many lavas and the contamination of natural remanent magnetization by lightning in many others. Moreover, we often observed the production of spurious high‐temperature chemical remanent magnetization during the Thellier experiments. An analysis of this particularly troublesome problem is presented. Two of the sites showed low paleointensities associated with angular departures of the paleomagnetic field direction from that of a geocentric axial dipole, which suggests that these excursions represent aborted reversals or fragments of reversals. At the third site, however, the paleointensity did not become low as the field diverged.
