The greisens contain varying amounts of disseminated cassiterite and wolframite. Several types of quartz veins are peripheral to the greisens; some of these contain minor wolframite. The deposit is genetically associated with a highly differentiated, peraluminous alkali-feldspar granite (587 + or - 8 Ma) that is part of a mostly peralkaline, igneous ring complex intruded into Late Proterozoic, immature sandstones of the Murdama Group. We recognize four distinct phases of the peraluminous granite. Only the smallest, most highly differentiated cupolas contain significant tin greisen mineralization. Greisens developed beneath aplitic carapaces that overlie the granite and created impermeable barriers to rising volatiles. The geometry of a cupola correlates strongly with the intensity of alteration; cupolas with the smallest cross sectional areas and steepest marginal contacts have the most intensely greisenized apexes. The paragenetic sequence can be divided into five stages: pegmatite formation, locally pervasive albitization, locally pervasive greisenization and deposition of cassiterite, deposition of quartz-wolframite veins, and deposition of quartz veins with minor base metal sulfides. Pressure-corrected fluid inclusion filling temperatures indicate that the hydrothermal system generally cooled as it evolved and that the delta&nbsp;</span><sup><span>18</span></sup><span>O values of the hydrothermal quartz increased from 10.8 to 15.7 per mil. Calculated delta&nbsp;<sup>18</sup>O</span><span>&nbsp;values of the hydrothermal fluid varied concomitantly from the pegmatite stage (delta&nbsp;<sup>18</sup>O</span><span>&nbsp;fluid approximately 8.6ppm; T [asymp] 550 degrees C) to the greisen stage (5.4 and 5.6[ppm; T [asymp] 360 degrees C), the quartz-wolframite vein stage (6.3 and 7.5ppm; T [asymp] 390 degrees C), and the late vein stage (4.0 and 5.1ppm; T [asymp] 270 degrees C). This evolution probably reflects the admixture of generally increasing amounts of meteoric or formation water having a lower delta&nbsp;</span><span>18</span><span>&nbsp;O value into the cooling magmatic hydrothermal system. In delta&nbsp;<sup>18</sup>O</span><span>-delta&nbsp;<sup>18</sup>O</span><span>&nbsp;plots for mineral separates from fresh to altered samples of the peraluminous granite the values for quartz and feldspar conform to a steep, positive-sloped disequilibrium trend that indicates interaction with high&nbsp;<sup>18</sup>O</span><span>&nbsp;hydrothermal fluid, mirrored by a negative-sloped disequilibrium trend for quartz and mica. These complementary trends suggest strongly that individual granite cupolas were essentially closed systems during alteration. To our knowledge, this is the first oxygen isotope demonstration of a closed-system, hydrothermal metal deposit. The sandstone country rock has whole-rock delta&nbsp;<sup>18</sup>O</span><span>&nbsp;values of 12.4 + or - 2.0 per mil. The highest values (&gt;13ppm) form a approximately 3-km-wide high delta&nbsp;<sup>18</sup>O</span><span>&nbsp;annulus immediately peripheral to the ring complex. The data suggest that the country rocks were pervasively exchanged with an outward-migrating, high delta&nbsp;<sup>18</sup>O</span><span>&nbsp;fluid moving down a temperature gradient. This fluid was probably formation water that flowed radially inward toward the pluton at a deeper level, forming a largely horizontal, unicellular flow system that had fluid-flow lines nearly vertical next to the intrusion, and directed upward and outward at higher levels. Low delta&nbsp;<sup>18</sup>O</span><span>&nbsp;fluids that formed quartz associated with the tin-tungsten mineralization and later veins are inferred to be the result of a subsequent and distinct phase of the hydrothermal system. Almost all the geologic processes necessary for the formation of an economically viable tin deposit occurred at Silsilah, but the lack of a strong localizing mechanism for cassiterite mineralization resulted in an economically marginal deposit. If the greisenized cupolas had been vertically stacked, as are the intrusions and ore zones in Climax-type molybdenum deposits, or if the mineralizing fluids had been channeled into veins, as in the tin deposits in Cornwall, England, a higher grade deposit might have formed. The generally closed-system behavior of the hydrothermal system at Silsilah may have prevented additional scavenging of metals and the formation of a larger, richer deposit.</span></p>","language":"English","publisher":"Economic Geology Pub.

Totals of 438 species, 281 genera, and 93 families of vascular plants were discovered, representing 40% of the flora of Ross County, and 17% of the flora of Ohio. Introduced species constituted 32% of the flora. Sixty-five species are new records for Ross County.

From April through September 1993, water samples were collected from 50 shallow domestic wells and 50 springs in the Springfield Plateau and Ozark aquifers and analyzed for 47 pesticides and metabolites. Pesticides were detected in 17 water samples from the Springfield Plateau aquifer and 12 water samples from the Ozark aquifer. Fourteen pesticides were detected, with a maximum of four pesticides detected in any one sample. The most commonly detected pesticides were atrazine (14 detections), prometon (11 detections), and tebuthiuron (seven detections).

Both shallow (2.0–2.6 km depth) breakout data and deep (20–45 km depth) crustal earthquake focal mechanisms indicate a N to NNE maximum horizontal compression in the vicinity of the Paleozoic Amazonas rift in central Brazil. This compressive stress direction is nearly perpendicular to the rift structure and represents a ∼75° rotation relative to a regional E‐W compressive stress direction in the South American plate. Elastic two‐dimensional finite element models of the density structure associated with the Amazonas rift (as inferred from independent gravity modeling) indicate that elastic support of this dense feature would generate horizontal rift‐normal compressional stresses between 60 and 120 MPa, with values of 80–100 MPa probably most representative of the overall structure. The observed ∼75° stress rotation constrains the ratio of the regional horizontal stress difference to the rift‐normal compressive stress to be between 0.25 and 1.0, suggesting that this rift‐normal stress may be from 1 to 4 times larger than the regional horizontal stress difference. A general expression for the modification of the normalized local horizontal shear stress (relative to the regional horizontal shear stress) shows that the same ratio of the rift‐normal compression relative to the regional horizontal stress difference, which controls the amount of stress rotation, also determines whether the superposed stress increases or decreases the local maximum horizontal shear stress. The potential for fault reactivation of ancient continental rifts in general is analyzed considering both the local stress rotation and modification of horizontal shear stress for both thrust and strike‐slip stress regimes. In the Amazonas rift case, because the observed stress rotation only weakly constrains the ratio of the regional horizontal stress difference to the rift‐normal compression to be between 0.25 and 1.0, our analysis is inconclusive because the resultant normalized horizontal shear stress may be reduced (for ratios &gt;0.5) or enhanced (for ratios &lt;0.5). Additional information is needed on all three stress magnitudes to predict how a change in horizontal shear stress directly influences the likelihood of faulting in the thrust‐faulting stress regime in the vicinity of the Amazonas rift. A rift‐normal stress associated with the seismically active New Madrid ancient rift may be sufficient to rotate the horizontal stress field consistent with strike‐slip faults parallel to the axis of the rift, although this results in a 20–40% reduction in the local horizontal shear stress within the seismic zone. Sparse stress data in the vicinity of the seismically quiescent Midcontinent rift of the central United States suggest a stress state similar to that of New Madrid, with the local horizontal shear stress potentially reduced by as much as 60%. Thus the markedly different levels of seismic activity associated with these two subparallel ancient rifts is probably due to other factors than stress perturbations due to dense rift pillows. The modeling and analysis here demonstrate that rift‐normal compressive stresses are a significant source of stress acting on the lithosphere and that in some cases may be a contributing factor to the association of intraplate seismicity with old zones of continental extension.</p></div><div class=\"accordion article-accordion\"><h2><br

In addition to anorthositic and felsic intrusions, the Duluth Complex is composed of many individual mafic layered intrusions of tholeiitic affinity. The cumulate stratigraphies and cryptic variations of six of the better exposed and better studied intrusions are described here to demonstrate the variability in their cumulus mineral paragenesis. Although the general paragenetic sequence is: O1(±Pl) → Pl+Ol → Pl+Cpx+Ox(±Ol±Opx) → Pl+Cpx+Ox+Ap(±Ol) considerable differences exist among the six intrusions in the relative order and timing of cumulus arrivals, most notably with regard to augite (Cpx) and Fe-Ti oxide (Ox).</div><div id=\"simple-para.0015\" class=\"u-margin-s-bottom\">The various cumulate stratigraphies and cryptic variations represented by the six intrusions described here largely reflect differences in the degree of open-system behaviour to recharge, eruption, and country-rock assimilation, but also may have been influenced by differences in parent magma composition, in the efficiency of fractional crystallization, and in the conditions of crystallization (<i>e.g.</i><span>&nbsp;</span>P<sub>total</sub>, f<sub>O2</sub><span>&nbsp;</span>P<sub>H2O</sub>). The Sonju Lake intrusion, wherein cumulus augite arrived before ilmenite, formed by essentially closed-system fractional crystallization. However, its compositional evolution may have been affected to an uncertain degree by assimilation of a granitic hanging-wall. The monotonous, thick troctolitic cumulate sequences of the lower parts of the South Kawishiwi and Partridge River Intrusions appear to represent the effects of frequent magma recharge coupled with<span>&nbsp;</span><i>in situ</i><span>&nbsp;</span>(or boundary layer) crystallization though other interpretations have been proposed. Extensive Cu-Ni sulphide mineralization at the base of these intrusions is attributed to country-rock contamination of the earliest intruded magmas. The cyclical progression of cumulates in the Layered Series at Duluth, wherein cumulus augite and oxide arrived nearly simultaneously, formed in a moderately open system characterized by periodic eruption and recharge. The Wilder Lake Intrusion is different from other intrusions in that cumulus ilmenite appears before augite and that olivine and augite composition define an inverted cryptic variation. The latter phenomenon may be related to a strong upward gradation toward lesser amounts of trapped liquid in the cumulates. Finally, the incomplete cumulate stratigraphy of the Bald Eagle Intrusion, which is composed of approximately equal thicknesses of troctolite (PO) and gabbro (PAO) adcumulates, is unique in that Fe-Ti oxide did not arrive as a cumulus phase despite prolonged crystallization of cumulus augite. These different cumulus parageneses probably produced a variety of derivative magmas, which may have contributed in part to the compositional diversity of the Midcontinent rift volcanics.</div>","language":"English","publisher":"Elsevier","doi":"10.1016/S0167-2894(96)80010-8","usgsCitation":"Miller, J., and Ripley, E., 1996, Layered intrusions of the Duluth Complex, Minnesota, USA: Developments in Petrology, v. 15, p. 257-301, https://doi.org/10.1016/S0167-2894(96)80010-8.","productDescription":"45 p.","startPage":"257","endPage":"301","numberOfPages":"45","costCenters":[],"links":[{"id":227133,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"15","noUsgsAuthors":false,"publicationDate":"2007-09-28","publicationStatus":"PW","scienceBaseUri":"505a4593e4b0c8380cd6741d","contributors":{"editors":[{"text":"Cawthorn R.G.","contributorId":128377,"corporation":true,"usgs":false,"organization":"Cawthorn R.G.","id":536432,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Miller, J.D.

PDTs are a principal source of information for the Science Advisory Committee, which is a standing committee charged with the duty of making recommendations to the Program Office based upon overall program objectives. PDT-1 focused on theoretical issues, and PDT-2 on observational issues; PDT-3 is the first of several to focus on more specialized topics. PDT-3 was convened to identify forecasting problems related to U.S. coastal weather and oceanic conditions, and to suggest likely solution strategies. There were several overriding themes that emerged from the discussion. First, the lack of data in and over critical regions of the ocean, particularly in the atmospheric boundary layer, and the upper-ocean mixed layer were identified as major impediments to coastal weather prediction. Strategies for data collection and dissemination, as well as new instrument implementation, were discussed. Second, fundamental knowledge of air-sea fluxes and boundary layer structure in situations where there is significant mesoscale variability in the atmosphere and ocean is needed. Companion field studies and numerical prediction experiments were discussed. Third, research prognostic models suggest that future operational forecast models pertaining to coastal weather will be high resolution and site specific, and will properly treat effects of local coastal geography, orography, and ocean state. The view was expressed that the exploration of coupled air-sea models of the coastal zone would be a particularly fruitful area of research. PDT-3 felt that forecasts of land-impacting tropical cyclones, Great Lakes-affected weather, and coastal cyclogenesis, in particular, would benefit from such coordinated modeling and field efforts. Fourth, forecasting for Arctic coastal zones is limited by our understanding of how sea ice forms. The importance of understanding air-sea fluxes and boundary layers in the presence of ice formation was discussed. Finally, coastal flash flood forecasting via hydrologic models is limited by the present accuracy of measured and predicted precipitation and storm surge events.

Buck Lake is located in southern Oregon just east of the crest of the Cascade Range. Lacustrine sediments, from 5.2 to 19.4 m in depth in core, contain tephra layers with ages of ≈300–400 ka at 9.5 m and ≈400–470 ka at 19.9 m. In these sediments magnetic properties reflect the absolute amount and relative abundances of detrital Fe-oxide minerals, titanomagnetite and hematite. The lacustrine section is divided into four zones on the basis of magnetic properties. Two zones (19.4–17.4 m and 14.5–10.3 m) of high magnetic susceptibility contain abundant Fe oxides and correspond closely to pollen zones that are indicative of cold, dry environments. Two low-susceptibility zones (17.4–14.5 m and 10.3–5.3 m) contain lesser amounts of Fe oxides and largely coincide with zones of warm-climate pollen. Transitions from cold to warm climate based on pollen are preceded by sharp changes in magnetic properties. This relation suggests that land-surface processes responded to these climate changes more rapidly than did changes in vegetation as indicated by pollen frequencies. Magnetic properties have been affected by three factors: (1) dissolution of Fe oxides, (2) variation in heavy-mineral content, and (3) variation in abundance of fresh volcanic rock fragments. Trace-element geochemistry, employing Fe and the immobile elements Ti and Zr, is utilized to detect postdepositional dissolution of magnetic minerals that has affected the magnitude of magnetic properties with little effect on the pattern of magnetic-property variation. Comparison of Ti and Zr values, proxies for heavy-mineral content, to magnetic properties demonstrates that part of the variation in the amount of magnetite and nearly all of the variation in the amount of hematite are due to changes in heavy-mineral content. Variation in the quantity of fresh volcanic rock fragments is the other source of change in magnetite content. Magnetic-property variations probably arise primarily from changes in peak runoff. At low to moderate flows magnetic properties reflect only the quantities of heavy minerals derived from soil and highly weathered rock in the catchment. At high flows, however, fresh volcanic rock fragments may be produced by breaking of pebbles and cobbles, and such fragments greatly increase the magnetite content of the resulting sediment. Climatically controlled factors that would affect peak runoff levels include the accumulation and subsequent melting of winter snow pack, the seasonality of precipitation, and the degree of vegetation cover of the land surface. Our results do not distinguish among the possible contributions of these disparate factors.</p></div>","language":"English","publisher":"Geological Society of America","doi":"10.1130/0016-7606(1996)108<1328:ROMPCC>2.3.CO;2","issn":"00167606","usgsCitation":"Rosenbaum, J.G., Reynolds, R.L., Adam, D., Drexler, J., Sarna-Wojcicki, A., and Whitney, G., 1996, Record of middle Pleistocene climate change from Buck Lake, Cascade Range, southern Oregon - Evidence from sediment magnetism, trace-element geochemistry, and pollen: Geological Society of America Bulletin, v. 108, no. 10, p. 1328-1341, https://doi.org/10.1130/0016-7606(1996)108<1328:ROMPCC>2.3.CO;2.","productDescription":"14 p.","startPage":"1328","endPage":"1341","numberOfPages":"14","costCenters":[],"links":[{"id":227407,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Oregon","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -122.8751846376905,\n              42.899776590965416\n            ],\n            [\n              -122.8751846376905,\n              41.83648605920985\n            ],\n            [\n              -120.94159088769044,\n              41.83648605920985\n            ],\n            [\n              -120.94159088769044,\n              42.899776590965416\n            ],\n            [\n              -122.8751846376905,\n              42.899776590965416\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"108","issue":"10","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50e4a272e4b0e8fec6cdb5e3","contributors":{"authors":[{"text":"Rosenbaum, J.
