The Blue Ridge anticlinorium in northern Virginia is a part of an integrated deformational system spanning the area from the Piedmont to the Appalachian Plateaus. Deformation intensity within the system decreases from east to west. Differences of opinion have emerged concerning the central Appalachians as to whether the basement rocks exposed in the core of the Blue Ridge anticlinorium are rooted or are allochthonous. Available surface and subsurface stratigraphic and structural data suggest that the anticlinorium may be a rootless thick-skinned analogue to the rootless thin-skinned Powell Valley anticline in the Valley and Ridge. Both structures were produced during the Alleghenian orogeny by similar deformational processes. The form of the Powell Valley anticline is attributed to duplication of about 4,575 m (15,000 ft) of sedimentary rock during approximately 16 km (10 mi) of northwest movement above a subhorizontal décollement. Similarly, the form of the Blue Ridge anticlinorium is attributed to duplication of about 9,150 m (30,000 ft) of igneous, metamorphic, and sedimentary rock during a minimum of 59 km (37 mi) of northwest movement above an eastward continuation of a subhorizontal décollement within Cambrian sedimentary rocks beneath the Valley and Ridge. Thus, in northern Virginia there is a mixing of structural styles: the thick-skinned rootless Blue Ridge anticlinorium sits above a thin-skinned detachment. This relationship implies that thin- and thick-skinned styles are simply end members of a complex deformational process that includes a transition zone, where characteristics of both styles commingle. © 1979 Geological Society of America.

Varving of the diatomaceous clay suggests that the diatoms were deposited in a restricted basin or lagoonal area that had oxygen-deficient bottom waters. The Middle Miocene diatom assemblage of the Hawthorn is correlative with that of approximately the upper half of Miocene Lithologic Unit 16 of the Choptank Formation in the Chesapeake Bay region of Maryland and with the Serravallian Stage.

Miliolids and elphidiids predominate on the inner part of the shelf. Their dominance gives way to textulariids and bolivinids as the shelf edge is approached. Cassidulinids and nodosariids become prominent near the shelf edge and on the slope. Samples from the Blake Plateau are less rich in benthonic species and specimens but are strongly dominated by planktonic specimens. -from Authors

Two moderate (ML = 5) earthquakes have occurred within the network during the interval. No convincing preseismic or coseismic anomalies associated with those earthquakes have been identified. The deformation of the network can be described roughly by rigid body motion of the three blocks bounded by the two faults with accommodation occurring by right‐lateral strike slip on the San Andreas (13±2 mm/a) and Calaveras (17±2 mm/a) faults. The required slip rates are within the range of the observed fault creep on those faults. A more detailed analysis of the deformation indicates appreciable strain accumulation (0.4 μstrain/a tensor shear) within the block lying between the San Andreas and Calaveras faults. Many of the features of the observed deformation can be produced by an elementary dislocation model, indicating that most of the deformation is associated directly with slip on the major faults. The network is not extensive enough to define uniquely the relative motion across the San Andreas fault system, but the data are consistent with a value of about 38 mm/a. The rate of deformation in 1971–1978 was not uniform but rather appears to have been higher than normal in 1973–1974 and lower than normal in 1975–1976.

The average strain across the entire network is essentially a uniaxial north‐south contraction at the rate of about 0.3 μstrain/a. There is no substantial strain perpendicular to the Salton trough, indicating no tendency to either open or close that rift. The observed uniaxial north‐south contraction differs from a pure shear parallel to the major faults by a uniform dilatation of about −0.25 μstrain/a that is only partly explained. The shear strain across the network reaches a maximum near the San Jacinto fault and could be explained by right lateral slip at depth on that fault. The displacement pattern also suggests right lateral slip at depth on the San Jacinto fault with total right lateral relative movement near 50 mm/a across the 120‐km breadth of the network. The deformation appears to be uniform in time in the 1973–1977 interval. A dislocation model of the deformation suggests about 50±15 mm/a of relative right lateral slip at depth distributed between the San Andreas, San Jacinto, and Elsinore faults and demonstrates that a significant average dilatation can be generated by pure strike slip on several subparallel faults.

Sixteen nets are located along the San Andreas fault system between Point Reyes, California, and the United States‐Mexico border. Other locations are across the Garlock fault in California; across Puget Sound near Seattle, Washington; near Hanford in eastern Washington; near Hebgen Lake in Montana; across the Wasatch fault at Ogden, Utah; across the Rio Grande rift at Socorro, New Mexico; and Dixie Valley in Nevada; and at the northern end of Owens Valley on the California‐Nevada border. Implicit in the treatment are the assumptions that the strain was accumulating at a constant rate over the time period (within the interval 1970–1978) and over the local area (usually about 50‐km diameter) covered by the surveys. Of the nets located away from the San Andreas fault, only Ogden and Hebgen show significant strain accumulation. At Ogden the deformation is principally an east‐west compression of 0.23±0.05 μstrain/yr and at Hebgen Lake a northeast‐southwest extension of 0.17±0.03 μstrain/yr. Along the San Andreas fault system the rate of shear is 0.2 to 0.4μ/yr. The direction of shear agrees very well with the surface strike of nearby faults. This agreement is maintained even in regions like the ‘big bend,’ where both the fault strike and the observed shear direction are more westerly than they are elsewhere. Shear strain in northern California appears to be concentrated more closely on the faults, whereas in southern California the strain is a broader, smoother feature. In the San Francisco Bay area the strain data indicate slip at depth on both the San Andreas and the Calaveras faults. In addition to the observed shear the nets in California indicate a negative dilatation (areal decrease) of about 0.2 μstrain/yr. This dilatation is unexplained, but the following sources appear unlikely: (1) systematic survey error, (2) an association with the southern California uplift, (3) an association with the big bend in the San Andreas fault in Southern California, or (4) the result of the superposition of a uniaxial strain on the Pacific‐North American plate boundary shear.

Specifically, no evidence of an increment in compressional strain normal to the San Andreas fault at the time of the uplift was found. Geodolite measurements at four networks along the big bend independently indicate that the strain rate during the 1974–1977 episode of subsidence was essentially a uniaxial north‐south compression at the rate of about ⅓ μstrain/yr. Whether the 1974–1977 rate is significantly different from earlier rates determined by triangulation is not clear owing to a rather large variability in the earlier determinations.

The most likely cause of this rapid and unusually large surface deformation is a recent influx of molten or partially molten material to a location within the crust beneath Yellow-stone National Park.

It has long been known, from fish cultural experience, that in certain site specific locations, chronic problems can be expected with salmonid egg development and early fry mortality. However, fingerlings which survive usually grow normally. A complete explanation is lacking although several environmental factors have been proposed to account for this phenomenon. One, which has so far received little attention, is that nitrate levels in the ground and surface waters of many areas have been increasing significantly over historical background levels. Ammonia, urea, and other potential sources of nitrate can enter natural waters from a variety of sources, such as domestic or industrial sewage, animal feedlots, or seepage and return flows from agricultural lands. The latter may be the largest contributor, since billions of tons of nitrate fertilizers are applied to agricultural crops on a worldwide basis each year. In addition, intensive forest management techniques include the aerial application of nitrate fertilizer to increase the yield of wood products, while range management practices call for use of nitrates to increase forage production. The nitrate that is not taken up by plants ultimately appears in ground or surface waters.

Chemical analyses of water from monitor wells and backflow from the injection well indicate that organic carbon compounds are converted to CO2 and nitrate is converted to N2. These transformations are caused by bacteria immediately after injection, and are virtually completed within 100 m of the injection well. The zone near the injection well behaves like an anaerobic filter with nitrate respiring bacteria dominating the microbial flora in this zone.
Sodium thiocyanate contained in the waste is unaltered during passage through the injection zone and is used to detect the degree of mixing of injected waste liquid with native water at a monitor well 312 m (712 ft) from the injection well. The dispersivity of the injection zone was calculated to be 10 m (33 ft). Analyses of samples from the monitor well indicate 80 percent reduction in chemical oxygen demand and virtually complete loss of organonitriles and nitrate from the waste liquid during passage from the injection well to the monitor well. Bacterial densities were much lower at the monitor well than in backflow from the injection well.

The capture probability of each individual is assumed to be constant over time. Based on this model we give a nonparametric estimation procedure for population size. The estimator involves selecting one of a sequence of estimator which are each linear combinations of the capture frequencies. The individual estimators are derived from the generalized jackknife method. We also give a goodness of fit test for the model's assumption that individual capture probabilities do not change during the study. The robustness of the estimation procedure is investigated with a simulation study. By virtue of this study, and the theoretical nature of the estimator, it is judged to be robust to moderate variations in individual capture probabilities which may occur in commonly used short-term livetrapping studies.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Ecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Ecological Society of America","publisherLocation":"Brooklyn, NY","doi":"10.2307/1936861","usgsCitation":"Burnham, K., and Overton, W., 1979, Robust estimation of population size when capture probabilities vary among animals: Ecology, v. 60, no. 5, p. 927-936, https://doi.org/10.2307/1936861.","productDescription":"10 p.","startPage":"927","endPage":"936","numberOfPages":"10","costCenters":[],"links":[{"id":291966,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":291965,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2307/1936861"}],"volume":"60","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53e9d8d4e4b008eaa4f3f68e","contributors":{"authors":[{"text":"Burnham, K.P.","contributorId":63760,"corporation":false,"usgs":true,"family":"Burnham","given":"K.P.","email":"","affiliations":[],"preferred":false,"id":497859,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Overton, W.S.","contributorId":47488,"corporation":false,"usgs":true,"family":"Overton","given":"W.S.","email":"","affiliations":[],"preferred":false,"id":497858,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70012494,"text":"70012494 - 1979 - Contribution of groundwater modeling to planning","interactions":[],"lastModifiedDate":"2025-04-10T16:56:14.014137","indexId":"70012494","displayToPublicDate":"1979-10-01T00:00:00","publicationYear":"1979","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2342,"text":"Journal of Hydrology","active":true,"publicationSubtype":{"id":10}},"title":"Contribution of groundwater modeling to planning","docAbstract":"The consideration of groundwater in water-resource planning frequently has been neglected because many planners believed that groundwater could not be adequately evaluated in terms of availability, quality, cost of development, or effect of development on the surface-water supply. The development of predictive groundwater models now provides the water planner with tools to evaluate these problems. Highly sophisticated digital models can be used in planning the development of groundwater and the conjunctive use of ground- and surface water. About 250 digital models have been used to evaluate groundwater problems: The models are powerful tools for predicting the response of groundwater systems to stresses. They can also clarify the cause and progress of past stresses. With these developments it is now possible to integrate the utilization of groundwater into water-resource planning with a high degree of confidence.

A controlled field experiment was conducted to ascertain the validity of the rate calculations made using this method. The vertical velocity, or leakage, of groundwater between two aquifers was calculated utilizing both hydrologic and temperature measurements in a well drilled into the Paw Paw buried bedrock valley in northern Illinois.
The experiment showed that accurate estimates of leakage can be made in stable boreholes where there are no geologic complications. Estimates utilizing temperature and hydrologic methods produced similar results for one of two aquicludes. However, the methods produced dissimilar results for the second aquiclude. It is speculated that the presence of a thin organic silt caused most of the problem; other complicating factors were lithologic variation and a very low hydraulic gradient. Nevertheless, the method appears to have great promise in many geologic environments.

These factors affect the geochemical environment of the sediments and therefore the distribution of trace elements reported to be present. The near-shore, sandy-bottom and fine-grained, soft, deep-lake sediments were investigated; areas of hard till or bedrock were not included in the study.
Thirty-three piezometers were placed in near-shore sands in waters 5-15 m deep. The piezometers were placed an average of 3 m into the bottom sediment. Water levels from the piezometers averaged 0.6 cm above the lake level, equivalent to an upward hydraulic gradient of about 0.002 cm/cm. Water samples taken from the piezometers have a distinctly different chemical composition from that of the lake water. The total dissolved mineral content and hardness of the groundwater are about twice those of the lake water.
Twenty-two hydraulic gradient measurements were made in the fine-grained soft deep-lake sediments in waters 48-140 m deep by using a differential-pressure transducer dropped into the sediments. These measurements show an upward gradient averaging 0.2 cm/cm. No chemical data were obtained for the groundwater in the deep-lake sediments.
The results of this study indicate that the groundwater flux is upward through the bottom sediments into Lake Michigan and that there is a chemical change in the water near the water-sediment contact.
