Controls inherited from sedimentation and preore diagenesis","docAbstract":"

Mineable zones of the Spar Lake deposit occur where argentiferous copper sulfides and native silver formed cements and replaced certain earlier cements and clasts in the gently dipping middle quartzite beds of the upper member of the Revett Formation, middle Proterozoic Belt Supergroup. The copper sulfides and native silver are part of a large, zoned system of authigenic ore and gangue minerals at Spar Lake. Mineral zone boundaries of ore and gangue phases cross all five stratigraphic units of the upper member.Deduced depositional environments for the host sedimentary rocks include beach and near-shore slope environments for the lower quartzite beds and subtidal(?) channels for the middle quartzite beds. The deposit must be epigenetic because mineral zone boundaries cross every facies in the sequence of beach and nearshore slope sediments.Mineral zonation has been mapped, and seven major associations, each named for its most abundant sulfide and/or most characteristic gangue cement, are recognized. Zones that appear to be developed on a regional scale include, in spatial order, pyrite-calcite, chalcopyrite-ankerite, and the lavender (hematitic) zone. Minor concentrations of base and precious metals occur along boundaries between the hematite and chalcopyrite-ankerite zones, and between the chalcopyrite-ankerite and pyrite-calcite zones; however, at the major concentrations of metals in the Revett Formation, including the Spar Lake deposit, additional mineral zones are developed between the chalcopyrite-ankerite and pyrite-calcite regional zones. Mineral zones at the deposit are, from northwest to southeast: pyrite-calcite, galena-calcite, chalcopyrite-calcite, bornite-calcite, chalcocite-chlorite, and chalcopyrite-ankerite. Gangue minerals, including carbonates, Fe-Ti oxides, chlorite, barite, authigenic feldspars, and apatite, are zonally distributed with boundaries parallel to the sulfide-mineral zone boundaries. Bornite-calcite and chalcocite-chlorite zones form ore grades in certain, but not all, quartzite intervals.As observed at unmetamorphosed deposits where sulfide-mineral zonation is similar, some pyrite-calcite-zone minerals were probably replaced by galena-calcite-zone minerals, which were probably succeeded, in sequence, by minerals of the chalcopyrite-calcite, bornite-calcite, and chalcocite-chlorite zones. This inferred paragenesis suggests that the chalcocite-chlorite zone is more proximal to the source of ore solutions than the galena-calcite or pyrite-calcite zones. The subeconomic chalcopyrite-ankerite zone, found farthest to the southeast at the Spar Lake deposit, was apparently even more proximal to the source than ore. Ore deposition took place during diagenesis from solutions that migrated upward and laterally through the sediments from a southeasterly source.The distributions of mineral zones and ore grades were controlled by two factors, one inherited from sedimentation and the other from preore diagenesis. All mineral zones spread out within coarser grained portions of quartzite units, suggesting that lateral migration of ore solutions was controlled by primary permeability of the sediments. However, high grades of copper and silver are found only in certain of the coarser grained beds. The distributions of higher grades suggest that ore mineral abundances reflect the abundances of preore diagenetic phases which were involved in the ore precipitation reactions. Preore reactant phases were evidently more abundant in sandstones deposited in subtidal(?) channels (the ore-grade middle quartzite beds) than in sandstones deposited in beach and nearshore slope environments (the lower quartzite beds). The identity of the reactant phases and the processes that resulted in their concentration at the site of later ore deposition remain unknown, although a preore sulfide- and hydrocarbon-bearing pore fluid appears to be the best hypothesis as to the identity of the reactants.

Cordell and Grauch (1982, 1985) discussed a technique to estimate the location of abrupt lateral changes in magnetization or mass density of upper crustal rocks. The final step of their procedure is to identify maxima on a contoured map of horizontal gradient magnitudes. We attempt to automate their final step. Our method begins with gridded magnetic or gravity anomaly data and produces a plan view of inferred boundaries of magnetic or gravity sources. The method applies to both local surveys and to continent-wide compilations of magnetic and gravity data (e.g., Zietz, 1982; Simpson et al., 1983a; Kane et al., 1982).

This investigation assesses geographic variations in atmospheric deposition in Washington, Oregon, and California using snow cores from the Cascade-Sierra Nevada Mountains, collected from late February to mid-March 1983. A statistical analysis of the analytical and sampling precision was made. The snowpack in the higher Cascades and Sierra Nevada is not strongly influenced by anthropogenic activities at present. The pH of snow samples ranges from 5.11 to 5.88. Sulfate and nitrate correlate with H+ in some segments of the sample traverse. The SO4 data show apparent influence from major source areas in Washington and California; nitrate does not. An apparent decrease in NH4 in snow in Washington and California suggests atmospheric interactions resulting in the removal of NH4. The NH4 reduction raises questions about nutrient supply to the mountain vegetation. Heavy-metal correlations included Cd, Cu, and Fe with Pb, and Mn with K and DOC, among others. No correlation was found between constituents and snow-water content.

An inductively coupled plasma atomic fluorescence spectrometric (ICP-AFS) method was used for the determination of nine elements in natural water. Reference and acid mine water samples were analysed by this method to demonstrate its usefulness for hydrogeochemical exploration. The elements were determined in two groups based on the compatibility of operating conditions and consideration of element abundance levels in natural water. Ca, Mg and Na were determined as a group using one set of instrumental conditions and a 1 + 99 dilution of the sample, and Cd, Cu, Fe, K, Li and Zn were determined using another set of conditions and the undiluted sample. The detection limits for the elements are as follows: Ca, 1.4; Mg, 1.7; Na, 2.0; Cd, 1.8; Cu, 6.2; Fe, 15.8; K, 3.5; Li, 0.3; and Zn, 1.2 ng ml–1. Each element has a linear range spanning about four orders of magnitude. The method has good precision and accuracy, as shown by statistics on replicate analyses and by the agreement between values obtained and those recommended for the reference water samples, and also those obtained by atomic absorption spectrometry for the acid mine water samples.

Underwater plants are a valuable part of the Great Lakes ecosystem, providing food and shelter for aquatic animals. Aquatic plants also help stabilize sediments, thereby reducing shoreline erosion. Annual fall die-offs of underwater plants provide food and shelter for overwintering small aquatic animals such as insects, snails, and freshwater shrimp.

\n

In some areas, underwater plants may be the dominant primary producer in the food chain supporting animal populations. Fish, for example, are usually more abundant where underwater plants are found. Plants and associated animals are a source of food for fish and waterfowl in the Great Lakes (Table 1). Despite the importance of underwater plants in the Great Lakes, very little is known about them, partly because of the difficulty of observing the plants in their natural habitat.

\n

The purpose of this field guide is to aid in the identification of common underwater plants in the Great Lakes. These plants are found mostly in shallow, nearshore waters along sheltered bays, peninsulas, and the four connecting rivers of the Great Lakes, including the St. Lawrence River (Figure 1). Connecting rivers are especially favorable for aquatic plants because they are shallow, have a consistent flow of water, and are protected from heavy wave action typical of other Great Lakes shorelines.

It was highly sensitive to differences among samples and consistently provided ecologically meaningful species ordinations. Gradients related to seasonality of taxa and year-to-year differences in population densities were evident in DCA ordinations if data for all sampling dates were included, and these gradients complicated interpretation of the copper gradient.

Paleomagnetic measurements and K‐Ar age determinations on volcanic rocks from Long Valley caldera, California, have enabled further refinement of eruptive activity within this large silicic volcanic center. K‐Ar age determinations show that postcaldera volcanic eruptions began 0.73 m.y. ago and continued periodically until about 50,000 years ago. The eruptions were not temporally random but tended to occur in distinct episodes separated by periods of quiescence. Volcanism in the western half of the caldera was particularly intense between 0.15 and 0.50 m.y. ago, when many units ranging in composition from basalt to rhyolite were erupted. An average of the virtual geomagnetic poles for 33 units from the caldera yields a paleomagnetic pole at 89.7°N, 138.4°E, (α95 = 5.1°), which is indistinguishable from the earth's rotational axis. The ancient geomagnetic field dispersion about this mean pole is 16.0°, with upper and lower limits of 19.3° and 13.6°, respectively.

Researchers in geomorphology, geochemistry, quaternary geology, soil science, and mineralogy will welcome this volume, the first to focus exclusively on rates of silicate chemical weathering. Consisting largely of previously unpublished data from six countries, the volume examines the latest experimental, modelling, and field results.

New information is presented on topics of current research interest, including inferences about chemical mechanisms at the level of mineral surfaces, and data relating weathering rates to landscape evolution over millions of years. The volume integrates the variety of approaches used by diverse subdisciplines in the assessment of weathering rates, and provides up-to-date references.

Examination of grades, tonnages, and basement rocks for 88 epithermal precious- and base-metal quartz-adularia-type districts in North, Central, and South America, and Japan reveals that the type of basement rock below the mineralized veins is useful for predicting grade and size of deposits. Epithermal districts overlying basement with salt and evaporites, or rocks with trapped sea water, have a median tonnage (production and reserves) of 1.4 million metric tons and median grades of 1.5g/t Au, 130g/t Ag, 2.5%Pb, 1.7%Zn, and 0.16%Cu. Districts overlying sedimentary basements have a median tonnage of 0.77 million metric tons and median grades of 7.5g/t Au, 110g/t Ag, <0.025%Zn, <0.005%Cu, and <0.001%Pb. Districts overlying igneous basements have a median tonnage of 0.3 million metric tons and median grades of 5.9g/t Au, 38g/t Ag, <0.25%Zn, <0.002%Cu, and <0.003%Pb. This investigation suggests that basement rocks affect vein components in epithermal precious- and base-metal quartz-adularia-type deposits.

At the Reeds Creek (West Virginia) state hatchery, mortality from enzootic furunculosis is most severe among brown trout Salmo trutta, intermediate in brook trout Salvelinus fontinalis, and virtually nonexistent in rainbow trout Salmo gairdneri. In each species, survivors of epizootics had developed similar levels of protective antibodies in their sera as demonstrated by microtiter agglutination and passive immunization experiments. We concluded that serum antibodies were not related to graded differences in resistance to furunculosis. These same fishes, however, produced a mucus precipitin that reacted with cell‐free bacterial extracts in single‐radial immunodiffusion assays. The mucus precipitin activity correlated with the resistance of the three species to furunculosis. Breeding studies with brown trout also showed that fish selected for a high level of mucus precipitin activity against Aeromonas salmonicida, the cause of fish furunculosis, produced progeny that were more resistant to furunculosis than other progeny produced from random matings. The nonspecificity of the mucus precipitin reaction was also confirmed by reactions with cell‐free extracts from Vibrio anguillarum and Aeromonas hydrophila.

The Clarno Formation, a mostly Eocene and partly early Oligocene sequence of andesitic lavas and volcaniclastic rocks, is the oldest Tertiary formation exposed in north central Oregon. Remanent magnetization directions at 46 sites in the lavas provide a paleomagnetic pole at 84°N, 278°E with a 95% confidence cone of 7°. Comparison of this pole with the North American reference pole for Eocene time indicates that the Clarno Formation has rotated 16° clockwise with an uncertainty of 10° but has undergone no significant latitudinal displacement. Further comparison with paleomagnetic data from the Miocene Columbia River Basalt Group and Steens Basalt shows that large‐scale block rotations in the eastern Columbia Embayment ceased sometime between 38 m.y. and 15 m.y. A paleogeographic reconstruction for 38 m.y. is offered which is consistent with the observed rotation of the Clarno and with the other paleomagnetic data from the Pacific Northwest, which are briefly reviewed. This reconstruction shows that it is possible to account for virtually all of the paleomagnetically indicated rotations in pre‐Miocene Tertiary rocks of the Pacific Northwest by an extensional tectonic model. As a consequence, only part of the rotations in the pre‐Tertiary rocks of the eastern Columbia Embayment need to be the result of accretionary tectonics. The initiation of magmatism in the eastern Columbia Embayment that is represented by the Clarno Formation itself may have been contemporaneous with the beginning of crustal extension in the Pacific Northwest.

Published distributional records for the stipitate kelp Pleurophycus gardneri Setchell and Saunders 1900 (Phaeophyceae: Laminariaceae) indicae a geographic range from Montague Island (59°58’N, 147°22W), Alaska to Fort Bragg (39°27’N, 123°47’W), California (Druehl 1969, 1970; Kjeldsen 1972). P. gardneri is found primarily in rocky intertidal and shallow subtidal locations (Scagel 1967; Nicholson 1976). In California, populations of P. gardneri have been reported only from the lower rocky intertidal near Fort Bragg (Kjeldsen 1972).

On 7 and 8 July 1982 and 23 March 1984 we censused stipitate kelps during SCUBS dives at a site 2.3 km south southeast of Pt. Sierra Nevada (35°41’ N, 121°18’W). we counted kelps in 1 x 5-m plots along a 50-m tape laid across the bottom in an arbitrarily predetermined direction from the skiff anchor. We also measured water depth at 1-m intervals along the tape, using a SCUBA depth gauge. On 20 August 1982, we used the same tehniques to sample kelp densities at a site 2.4 km east southeast of Pt. Piedras Blancas (35°39’N, 121°15’W).

The most abundant kelps at the Pt. Sierra Nevada ste were Pterygophora californica Ruprect 1852 (Phaeophyceae: Alariaceae) and a species we tentatively identified as P. gardneri (Table 1). Based on specimens we collected on 8 July 1982, our field identification was subsequently confirmed by I. A. Abbot. Voucher specimens were placed in the Gilbert M. Smith Herbarium at Hopkins Marine Station, Stanford University, Pacific Grove, California.

The abundance and species composition of conspicuous fishes were compared within two canopy forming kelp forests (giant kelp, Macrocystis pyrifera, and bull kelp, Nereocystis luetkeana) in Central California. The primary investigative method was a subtidal belt transect, in which visual observation was used. The species composition of fish assemblages in the two canopy types was similar. Densities of fish were generally greater in Macrocystis than in Nereocystis forests. The major difference was the density of midwater species of the genus Sebastes. The blue rockfish, Sebastes mystinus, was the numerically dominant species in both canopy types. Estimates of the biomass of fish were about 2.4 times greater in Macrocystis beds than in Nereocystis beds.
