The occurrence of the second known specimen of Parahyus vagus, from the Tepee Trail Formation, Wyoming, is recorded. As the first specimen was reported from the lower Eocene, this second occurrence casts doubt on the supposed age ranges of both Parahyus and the Tepee Trail.

Ore-stage pyrite forms as the result of redistribution and accretion from the preore pyrite. Accretion of the ore-stage pyrite seems to be governed by natural laws that limit its concentration to only a few times the concentration of the preore pyrite. Accumulations of ore-stage pyrite build up along the leading edge of a supergene oxidation zone which spreads through the host rocks, literally pushing the ore deposits ahead of it. The ore-stage pyrite probably progresses much as a wave that first grows to a nearly fixed amplitude and thereafter is steadily maintained as the mature deposit continues to advance.

The first step in the study of such a mixture is the fractionation of the mixture. The most common approach with humic acids is to attempt to obtain a molecular weight fractionation by gel-permeation chromatography. However, since the preponderance of evidence indicates that the components of humic acid do not fulfill the basic criteria of uniform shape and chemical structure necessary for obtaining a molecular fractionation on gel-permeation media, molecular weight distributions in humic acids cannot be
evaluated by this method. A fractionation dependent upon chemical structure can be obtained by the manipulation of elution conditions on
a gel-permeation column. This procedure provides a beginning in the isolation and identification of discrete components of humic acids.
A thick sequence of highly deformed flyschlike metasandstone, slate, and argillite crops out in southern Alaska in the Kenai-Chugach Mountains and on Kodiak and the Shumagin Islands to the southwest. These poorly fossiliferous rocks have long been considered Cretaceous in age because of scattered occurrences of fragmentary shells of Inoceramus. Mainly on the basis of new fossil collections, the age of some of these rocks can now be firmly established as Late Cretaceous (Maestrichtian); the critical fossil is Inoceramus kusiroensis Nagao and Matsumoto. Inoceramus kusiroensis also occurs in the much more fossiliferous and only slightly deformed Matanuska Formation that forms a parallel belt north of the Chugach Mountains. On the basis of faunal, lithologic, and bedding characteristics, the Matanuska Formation is the shelf equivalent of the deepwater, trench, or continental-rise deposits of the Kenai-Chugach Mountains and islands to the southwest. \"Inoceramya concentrica\" Ulrich occurs with Inoceramus kusiroensis and is Maestrichtian in age, not Early Jurassic as E. 0. Ulrich suggested
in 1910. The syntypes of I. concentrica are refigured and a lectotype is designated.
Many housing projects in the metropolitan area of Boston are beyond the reach of municipal sewer systems. Waste water disposed of through septic-tank or cesspool systems percolates to ground-water reservoirs and eventually reaches the streams. The dissolved-solids load in the streams receiving septic-tank effluent is increased by an amount that can be predicted from the housing density. In the study area, highway deicing salts are the only materials other than septic-tank discharge that contribute to water-quality degradation. The effect of these salts on the relationship with housing density is eliminated by subtracting the specific conductance due to sodium chloride from the measured specific conductance of a water sample. The difference is called residual conductance and is proportional to the dissolved-solids content minus the concentration of sodium chloride.

Although changes in water chemistry and lower biota have been generally modest (except locally), those in native fish stocks have been vast. Exploitation, exotic fish species, and eutrophication and other forms of pollution all have played a role in bringing about the changes (mostly declines in abundance) in fish populations. Exploitation resulted in a noticeable reduction in abundance of certain native species (especially whitefish) soon after the establishment of the commercial fishery in the 1840's. By the 1930's the sturgeon and the two largest deepwater ciscoes (Coregonus nigripinnis and C. johannae) became severely depleted. Other species- whitefish (Coregonus clupeaformis), lake trout (Salvelinus namaycush), and lake herring (C. artedii)- remained important commercially, but at a lower level of production than originally; greatly increased fishing effort and efficiency were required to maintain even these decreased catches. The catch of intermediate-size ciscoes held relatively stable, but again only through sharply increased fishing effort and efficiency. The earliest serious effects of exotic fish species on native fish stocks may have been during the 1930's, when smelt (Osmerus mordax), first became abundant. Powerful influences by exotics were not obvious, however, until the 1940's, when the sea lamprey's (Petromyzon marinus) predation on several species, particularly the lake trout, became critical. In the 1950's the sea lamprey was joined by the alewife (Alosa pseudoharengus), another exotic strongly deleterious to several native fish. The alewife apparently inhibited reproduction of deepwater ciscoes, yellow perch (Perca flavescens), deepwater sculpins (Myoxocephalus quadricornis), emerald shiners (Notropis atherinoides), and perhaps others (through competing with young, or feeding on them). At the same time, however, the alewife as a prolific forage fish has made possible the highly successful introduction of several species of salmonines. The effects of accelerated eutrophication and other pollution, although not always as easy to identify as the influences of other factors, were nevertheless clearly important as early as the mid-1800's. The first conspicuous contamination of Lake Michigan was by sawmill wastes, which covered spawning grounds in streams and around stream mouths. This type of pollution was particularly destructive to whitefish. Other forms of stream degradation (e.g., dams, deforestation of watersheds) although not strictly \"pollution,\" must also have been detrimental to stream spawners. Heavy pollution in southern Green Bay (a large area of the bottom of which is now covered with anoxic gray sludge) probably has resulted in reduction in abundance of several species, e.g., lake herring and walleye (Stizostedion v. vitreum).\nExploitation was largely responsible for the changes in Lake Michigan fish stocks before the invasion of the smelt, and probably before the invasion of the sea lamprey. The lamprey and alewife, however, have exerted a greater impact than the fishery on native fish populations in recent decades. Accelerated eutrophication and other pollution, although important, have not equalled the other factors in causing changes in native fish populations.","language":"English","publisher":"Great Lakes Fishery Commission","collaboration":"Out-of-print","usgsCitation":"Wells, L., and McLain, A.L., 1973, Lake Michigan: Man's effects on native fish stocks and other biota: Technical Report 20, 55 p.","productDescription":"55 p.","startPage":"0","endPage":"55","numberOfPages":"55","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":199179,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":92058,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://www.glfc.org/pubs/TechReports/Tr20.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b28e4b07f02db6b168a","contributors":{"authors":[{"text":"Wells, LaRue","contributorId":75476,"corporation":false,"usgs":true,"family":"Wells","given":"LaRue","email":"","affiliations":[],"preferred":false,"id":324984,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McLain, Alberton L.","contributorId":15561,"corporation":false,"usgs":true,"family":"McLain","given":"Alberton","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":324983,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":81361,"text":"81361 - 1973 - Unharvested fishes in the U.

The δ18O values correlate in general with lake salinities as inferred from geologic evidence, indicating that most chert was formed from its precursor in contact with lake water trapped at the time of deposition. A few of the analyzed cherts probably formed in contact with dilute meteoric water. From the widely varying δ18O values we conclude that precursors were transformed to chert in fluids of widely varying salinity and aNa+/aH+ ratio.
Electron microprobe analyses of green hornblende and coexisting cummingtonite from garnet amphibolite show identical Fe/Mg ratios ( = 0.9). Cummingtonite is iron-magnesium silicate with very little calcium and aluminum and practically no alkalies. In contrast, the hornblende has 1.5 tetrahedral Al, 0.9 octahedral Al and a considerable amount of Ca and alkalies. Comparison with the hornblendes from the Sierra Nevada shows a higher relative amount of tschemakite molecule in the hornblendes from Idaho where pressures during the recrystallization were higher.
Deuterium and O18 analyses were made on 25 formation-water samples from Miocene (Temblor Formation) and Eocene (McAdams Formation) reservoir rocks at Kettleman North Dome oil field, California, and on three surface water samples from Reef Ridge located about three miles to the west of the field. The δO18 values obtained generally increase with depth and most probably are due to temperature controlled exchange reactions with carbonate cement and dissolved carbonate species. The δD values obtained seem to be controlled primarily by the membrane behavior of shales modifying the assumed original values. The contribution of isotopic exchange between water and clays cannot be evaluated at present.
The isotopic data support the conclusions based on a detailed study of geology, hydrodynamics, and formation water geochemistry (Kharaka, 1971) which indicate that:
1. The Temblor Formation waters are probably meteoric in origin concentrated chemically and isotopically by shale membranes, and 2. The McAdams Formation waters were most probably obtained by squeezing the original interstitial marine connate waters of deposition from the underlying Mesozoic sediments.

Succeeding Cretaceous-Eocene sediments unconformably overlie this basement and extend outwards onto oceanic crust. Tertiary tectonism occurred in three distinct phases.
At the present time, the tectonics of the southwest Pacific are related to a series of opposite facing subduction (Benioff) zones connected by transform faults extending from New Britain-Solomon Islands south through the New Hebrides to New Zealand and marking the boundary between the Australian and Pacific plates. Available geologic data from this region suggest that a similar geometry existed during the Tertiary and that the microcontinents of New Guinea, New Caledonia and New Zealand all lay along the former plate boundary which has since migrated north and east by a complex process of sea-floor spreading behind the active island arcs.

The data indicate that the Luna 20 soil is mainly a mixture of highland anorthosites and low-K basalt, but little KREEP basalt. The U-Th-Pb systematics are discussed in comparison with other lunar soils, especially with Apollo 16 soils which were collected from a ‘typical’ highland region. The data fit well in the Apollo 16 soil array on a U-Pb evolution diagram, and they exhibit excess lead relative to uranium. This relationship appears to be a characteristic of highland localities. Considering the previous observations of lunar samples, we infer that lead enrichment in the soil relative to uranium occurred between 3.2 and 3.9 b.y. ago and that the soil was disturbed by ‘third events’ about 2.0 b.y. ago. A lunar evolution model is discussed.
