The older unit (Bed 3A of the Calvert Formation and its correlatives) was deposited in a relatively restricted basin of middle Burdigalian (middle early Miocene) age. The younger unit (Bed 3B of the Calvert Formation and its correlatives) was deposited in a much more widespread basin of late Burdigalian (late early Miocene) age. The older deposit was completely overlapped by the younger deposit. These two beds of substantially differing geologic age are difficult, if not impossible, to distinguish solely by lithostratigraphy. They are, however, readily differentiated on the basis of their distinctive silicoflagellate and diatom assemblages.

In an early application of numerical modeling techniques to the two-dimensional simulation of field-scale plumes, previous investigators identified longitudinal and transverse dispersivities using an independently calibrated steady-state flow model and matching contours of observed and simulated concentrations. The unusual result of calibrated transverse dispersivity (140 m) being significantly larger than longitudinal dispersivity (90 m) has been attributed to spatial heterogeneity, the fractured nature of the aquifer, and to the use of a two-dimensional model. New calibrations of the solute-transport model are performed on point concentration observations using a flow model incorporating transient recharge conditions that cause significant fluctuations in velocity. Under transient flow conditions, lowest calibration errors are achieved with significantly larger dispersivities than previously hypothesized, and with the longitudinal component larger than the transverse component. Unfortunately, the sensitivity of the model calibration error to dispersivity is low. Incorporating transient flow in this two-dimensional porous-media model does not significantly improve our understanding of the processes controlling chloride transport at this site.

Mine site case studies","docAbstract":"The effectiveness of preventing or ameliorating acid mine drainage (AMD) through the application of alkaline additives is evaluated for eight surface coal mines in Pennsylvania. Many of the mine sites had overburden characteristics that made prediction of post‐mining water quality uncertain. Alkaline materials were applied at rates ranging from 42 to greater than 1,000 tons as calcium carbonate per acre. In addition, two sites that were mined and reclaimed without alkaline additives are included for comparative purposes.
Overburden sulfur concentration and \"neutralization potential\" (NP) data for multiple strata at each mine site were used to compute the cumulative, mass‐weighted \"maximum potential acidity\" (MPA) and \"net neutralization potential\" (NNP = NP ‐ MPA) by using three different calculation methods. Post‐reclamation water‐quality data were used to compute the net alkalinity (= alkalinity ‐ acidity). The most conservative determination of NNP, whereby MPA is calculated by multiplying the total sulfur concentration, in weight percent, by 62.5 instead of 31.25, yielded the best agreement with net alkalinity (patching signs on NNP and net alkalinity). The error in prediction using each method was that the reclaimed overburden was computed to be alkaline overall (NNP > 0), but the post‐reclamation water was acid (net alkalinity < 0).
In general, alkaline addition rates were probably insufficient to neutralize, or too late to prevent, acid production in the mine spoil. At six of the seven mine sites that had overburden with insufficient NP relative to MPA (NNP < 0), the addition of alkaline materials failed to create alkaline mine drainage; AMD was formed or persisted. A control site which also had insufficient alkaline material, but did not incorporate alkaline additives, generated severe AMD. Two sites that had substantial, natural alkaline overburden produced alkaline drainage. Although the addition rates appear to be inadequate, other factors, such as unequal distribution and exposure of the acid‐forming or neutralizing materials and hydrogeological variability, complicate the evaluation of relative effectiveness of using different alkaline materials and placement of the acid‐ or alkaline‐producing materials.

This typically occurs when the horizontal length scale of the headland is comparable to or smaller than the tidal excursion. The effects of these headlands on dispersion are investigated using a depthaveraged hydrodynamic model combined with a particle tracking model. The dispersion of patches of fluid is found to vary by more than an order of magnitude, depending both on position and tidal phase at the time of release. This is due to the infrequent interaction of material with the strongly sheared flow at the tip of the headland, where flow separation occurs during times of maximum tidal flow. Spreading of these patches over many tidal cycles is not Gaussian, but rather shows a patchy, streaky structure.

Geochemical considerations","docAbstract":"The addition of alkaline materials to supplement deficient \"neutralization potential\" (NP) of mine spoil, and thus to prevent or abate acid mine drainage, has riot been successful at most surface coal mines in Pennsylvania. A basic problem may have been improper accounting for acid‐production potential and thus inadequate addition rates of calcium carbonate (CaCO3 ), calcium oxide (CaO) , or calcium hydroxide [ Ca (OH)2 ] at many mines. The commonly used acid‐base accounting method is based on the following overall reaction:
FeS2 + 2 CaCO3 + 3.75 O2 + 1.5 H2O --> Fe(OH)3 + 2 SO4-2 + 2 Ca+2 +2 CO2(g),
where the acidity from 1 mole of pyrite (FeS2) is neutralized by 2 moles of CaCO3 . This method presumes that gaseous carbon dioxide (CO2) will exsolve, and therefore may underestimate by up to a factor of 2 the quantity of CaCO3 required to neutralize the \"maximum potential acidity\" (MPA) in the mine spoil. This paper reviews some geochemical reactions involving FeS2 and various alkaline additives that support the argument that the acid‐base accounting method for computing MPA from overburden analyses should be revised. Considering the stoichiometry of the following overall reaction:
FeS2 + 4 CaCO3 + 3.75 O2 + 3.5 H2O --> Fe(OH)3 + 2 SO4-1 + 4 Ca+2 + 4 HCO3-,
4 moles of CaCO3 are required to neutralize the maximum potential acidity produced by the oxidation of 1 mole of FeS2 . Therefore, the multiplication factor for computing MPA from the overburden sulfur concentration, in weight percent, should be increased from 31.25 to 62.5.

Like the younger analogues, the volcanism within this older rift can be explained by decompression melting and rapid extrusion of igneous material during lithospheric extension above a broad, asthenospheric, thermal anomaly which we call the Keweenaw hot spot. Great Lakes International Multidisciplinary Program on Crustal Evolution seismic reflection profiles constrain end-member models of melt thickness and stretching factors, which yield an inferred mantle potential temperature of 1500°–1570°C during rifting. Combined gravity modeling and subsidence calculations are consistent with stretching factors that reached 3 or 4 before rifting ceased, and much of the lower crust beneath the rift consists of relatively high density intruded or underplated synrift igneous material. The isotopic signature of Keweenawan volcanic rocks, presented in a companion paper by Nicholson and Shirey (this issue), is consistent with our model of passive rifting above an asthenospheric mantle plume.

However, this relative plate motion cannot account for coeval convergence in the Ouachitas and Variscides and is incompatible with some tectonic transport indicators in the Appalachians. An alternative kinematic model is proposed in which early sinistral transpression in the Appalachians is followed by counterclockwise rotation of Gondwana and the development of a system of dextral strike-slip faults extending from southern Europe to Alabama.

Assuming uniform slip on a rectangular surface, the mean values for a range of reasonable fault geometries are 1.6 ± 0.3 m right‐lateral strike slip and 1.2 ±0.3 m reverse slip. Slip on an adjacent extension of the rupture to the southeast, recorded in the aftershock sequence, is not well constrained by the geodetic data.

Roughly 1.3 years before the earthquake, at about the time of the first magnitude‐5 foreshock, the rate of change in line length for two of the lines appears to change; the rate for the third line does not change. Other similar, though smaller, changes in rate are apparent in the eight‐year record. Thus, there is marginal evidence for a change in deformation rate about one year before the Loma Prieta earthquake, but that change need not be a precursor.

Each exhibits 0.14 μrad/yr simple right‐lateral engineering‐shear‐strain accumulation across the local vertical plane tangent to the small circle. Local faults (e.g., Owens Valley, Garlock, Helendale) traversing these networks are not as closely aligned with the vertical planes of maximum shear‐strain accumulation as is the local tangent to the small circle. A fifth network slightly east of the small circle shows no significant strain accumulation. Thus, a shear zone trending N35° W from near the eastern end of the big bend of the San Andreas fault to northern Owens Valley is indicated by these data. This corresponds to the Eastern California shear zone proposed on geological evidence by Dokka and Travis. The shear zone carries ∼8 mm/yr of the Pacific‐North America relative plate motion from the San Andreas fault north‐northwest across the Mojave Desert into Owens Valley and the northern Basin and Range province. The shear zone observed at the surface may be a manifestation of a through‐going subcrustal fault.

Recent evidence showed these early claims were exaggerated, but animal control was already entrenched in government policy. As a result, ongoing government subsidized poisoning has reduced prairie dogs to about 2% of their former distribution. The reduction of prairie dogs diminished species diversity in the arid grasslands of North America, including the potential extinction of the black-footed ferret (Mustela nigripes). Cost-benefit analysis revealed that poisoning costs more than any grazing benefits accrued. This analysis did not consider the long-term costs of reversing ecosystem degradation, the intangible value of biological diversity as a public benefit, or the depletion of biotic resources as a loss of actual or potential wealth. The government presently finances the poisoning policy and the preservation of endangered species like the black-footed ferret, two apparently conflicting programs. We, therefore, propose an integrated management plan that considers both interests. We propose that federal monies allocated to the poisoning program be converted into a rebate for ranchers who manage livestock while preserving the prairie dog community. This would redirect funds and personnel already allocated to prairie dog eradication to an incentive for ranchers who manage for livestock and wildlife. Livestock interests and grassland biotic diversity would both benefit.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Environmental Management","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer-Verlag","publisherLocation":"New York, NY","doi":"10.1007/BF02394170","usgsCitation":"Miller, B., Wemmer, C., Biggins, D., and Reading, R.P., 1990, A proposal to conserve black-footed ferrets and the prairie dog ecosystem: Environmental Management, v. 14, no. 6, p. 763-769, https://doi.org/10.1007/BF02394170.","productDescription":"7 p.","startPage":"763","endPage":"769","numberOfPages":"7","costCenters":[],"links":[{"id":293748,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":293747,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF02394170"}],"volume":"14","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5412b99be4b0239f1986b9fa","contributors":{"authors":[{"text":"Miller, Brian","contributorId":100753,"corporation":false,"usgs":true,"family":"Miller","given":"Brian","affiliations":[],"preferred":false,"id":500749,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wemmer, Christen","contributorId":40135,"corporation":false,"usgs":true,"family":"Wemmer","given":"Christen","email":"","affiliations":[],"preferred":false,"id":500747,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Biggins, Dean","contributorId":85519,"corporation":false,"usgs":true,"family":"Biggins","given":"Dean","affiliations":[],"preferred":false,"id":500748,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Reading, Richard P.","contributorId":104824,"corporation":false,"usgs":true,"family":"Reading","given":"Richard","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":500750,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":70124339,"text":"70124339 - 1990 - Development of survival skills in captive-raised Siberian polecats (Mustela eversmanni) I: locating prey","interactions":[],"lastModifiedDate":"2014-09-11T13:00:41","indexId":"70124339","displayToPublicDate":"1990-12-01T12:59:33","publicationYear":"1990","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2271,"text":"Journal of Ethology","active":true,"publicationSubtype":{"id":10}},"title":"Development of survival skills in captive-raised Siberian polecats (Mustela eversmanni) I: locating prey","docAbstract":"Captive-raised mustelids appear to have a rudimentary capacity to kill prey, but the skills necessary for locating prey may be eroded during captivity. We tested the maturational component of prey-searching behavior with captive-raised Siberian polecats (Mustela eversmanni) by subjecting polecats to a simulated prairie dog colony of 6 burrows within a 200 m2 arena. Ten naive Siberian polecats at ages 2.5, 3.5, and 4.5 months (30 total) were deprived of food for 12 hours. A dead prairie dog was placed in 1 prairie dog burrow and the other 5 were empty. A single Siberian polecat was released onto the colony shortly before sunset and its movements monitored from an observation tower. Older Siberian polecats located prey significantly quicker than younger polecats, but all age groups spent a great deal of time in surface activity not directed toward a burrow. When Siberian polecats were about 10 months old, all burrows in the arena were plugged with dirt including the burrow with the prairie dog. In this winter test, Siberian polecats located the prey but still spent a great deal of time in non-burrow directed surface activity. Economical use of surface time, with a low amount of non-burrow directed behavior, would presumably reduce the risk of predation for hunting polecats.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Ethology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer-Verlag Tokyo","publisherLocation":"Tokyo","doi":"10.1007/BF02350279","usgsCitation":"Miller, B., Biggins, D., Wemmer, C., Powell, R., Hanebury, L., Horn, D., and Vargas, A., 1990, Development of survival skills in captive-raised Siberian polecats (Mustela eversmanni) I: locating prey: Journal of Ethology, v. 8, no. 2, p. 89-94, https://doi.org/10.1007/BF02350279.","productDescription":"6 p.","startPage":"89","endPage":"94","numberOfPages":"6","costCenters":[],"links":[{"id":293729,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":293728,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF02350279"}],"volume":"8","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5412b9a3e4b0239f1986ba42","contributors":{"authors":[{"text":"Miller, Brian","contributorId":100753,"corporation":false,"usgs":true,"family":"Miller","given":"Brian","affiliations":[],"preferred":false,"id":500731,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Biggins, Dean","contributorId":85519,"corporation":false,"usgs":true,"family":"Biggins","given":"Dean","affiliations":[],"preferred":false,"id":500729,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wemmer, Chris","contributorId":55358,"corporation":false,"usgs":true,"family":"Wemmer","given":"Chris","email":"","affiliations":[],"preferred":false,"id":500725,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Powell, Roger","contributorId":83848,"corporation":false,"usgs":true,"family":"Powell","given":"Roger","affiliations":[],"preferred":false,"id":500728,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Hanebury, Lou","contributorId":87465,"corporation":false,"usgs":true,"family":"Hanebury","given":"Lou","email":"","affiliations":[],"preferred":false,"id":500730,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Horn, Deborah","contributorId":81822,"corporation":false,"usgs":true,"family":"Horn","given":"Deborah","email":"","affiliations":[],"preferred":false,"id":500726,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Vargas, Astrid","contributorId":82629,"corporation":false,"usgs":true,"family":"Vargas","given":"Astrid","affiliations":[],"preferred":false,"id":500727,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}} ,{"id":70124337,"text":"70124337 - 1990 - Development of survival skills in captive-raised Siberian polecats (Mustela eversmanni) II: predator avoidance","interactions":[],"lastModifiedDate":"2014-09-11T12:52:09","indexId":"70124337","displayToPublicDate":"1990-12-01T12:49:24","publicationYear":"1990","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2271,"text":"Journal of Ethology","active":true,"publicationSubtype":{"id":10}},"title":"Development of survival skills in captive-raised Siberian polecats (Mustela eversmanni) II: predator avoidance","docAbstract":"We exposed naive Siberain polecats (Mustela eversmanni) (aged 2, 3, and 4 months) to a swooping stuffed great horned owl (Buho virginianus) and a stuffed badger (Taxidae taxus) mounted on a remote control toy automobile frame. The first introduction to each was harmless, the second was accompanied by a mild aversive stimulus, the third (1 day after attack) was harmless, and the fourth (30 days after attack) was harmless. Alert behavior increased after a single attack by either predator model. Escape responses of naive polecats did not differ between ages when exposed to the badger, but 4 month old polecats reduced their escape times after a single badger attack. When exposed to the swooping owl, naive 4 month old polecats redponded more quickly than the other two age groups, and 3 and 4 month old polecats reduced escape times after a single owl attack. This indicates an innate escape response to the owl model at 4 months of age, and a short-tert ability to remember a single mild aversive encounter with the badger and owl models at 3 or 4 months of age.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Ethology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer-Verlag Tokyo","publisherLocation":"Tokyo","doi":"10.1007/BF02350280","usgsCitation":"Miller, B., Biggins, D., Wemmer, C., Powell, R., Calvo, L., Hanebury, L., and Wharton, T., 1990, Development of survival skills in captive-raised Siberian polecats (Mustela eversmanni) II: predator avoidance: Journal of Ethology, v. 8, no. 2, p. 95-104, https://doi.org/10.1007/BF02350280.","productDescription":"10 p.","startPage":"95","endPage":"104","numberOfPages":"10","costCenters":[],"links":[{"id":293720,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":293718,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/BF02350280"}],"volume":"8","issue":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5412b9a5e4b0239f1986ba47","contributors":{"authors":[{"text":"Miller, Brian","contributorId":100753,"corporation":false,"usgs":true,"family":"Miller","given":"Brian","affiliations":[],"preferred":false,"id":500719,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Biggins, Dean","contributorId":85519,"corporation":false,"usgs":true,"family":"Biggins","given":"Dean","affiliations":[],"preferred":false,"id":500717,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wemmer, Chris","contributorId":55358,"corporation":false,"usgs":true,"family":"Wemmer","given":"Chris","email":"","affiliations":[],"preferred":false,"id":500715,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Powell, Roger","contributorId":83848,"corporation":false,"usgs":true,"family":"Powell","given":"Roger","affiliations":[],"preferred":false,"id":500716,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Calvo, Lorena","contributorId":24291,"corporation":false,"usgs":true,"family":"Calvo","given":"Lorena","email":"","affiliations":[],"preferred":false,"id":500714,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Hanebury, Lou","contributorId":87465,"corporation":false,"usgs":true,"family":"Hanebury","given":"Lou","email":"","affiliations":[],"preferred":false,"id":500718,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Wharton, Tracy","contributorId":103194,"corporation":false,"usgs":true,"family":"Wharton","given":"Tracy","email":"","affiliations":[],"preferred":false,"id":500720,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}} ]}
