Fe metal. Swatching kamacite surrounding troilite in iron meteorites formed by nucleation at the troilite-metal interface during the formation of the Widmanstätten texture.The blue pike (Stizostedion vitreum glaucum) contributed about 12.7 million lb annually to the commercial production of fish in Lake Erie in 1915–59. Production averaged about 27% of the total for all species; in some years it exceeded 50%. The catch fluctuated greatly and was featured by a series of seven \"highs\" and \"lows\" during the 45-year period. The landings ranged between 2 million and 26 million lb; periods of peak production were 5 to 9 years apart. A sharp decline in the catch started in 1957. The take of 79,000 lb in 1959 was the lowest on record to that time.Age and size compositions of the catch were determined from samples of blue pike taken from commercial landings in the fall, 1943–59. Peaks in production in that period were attributed to a few strong year-classes separated by several weak year-classes. Of the 20 year-classes represented in the samples, those of 1944 and 1949 were by far the strongest; together they contributed 42% (by weight) of the fall blue pike production in 1943–59. The strength of the 1939 and 1940 year-classes was moderate and the 1954 year-class was the last one of any importance. The other 15 year-classes were weak.The 1957–59 decline in production was accompanied by a marked increase in rate of growth. Blue pike in age-group III weighed nearly eight times more and were 7.7 inches longer in 1959 than in 1951. Landings after 1958 consisted of only a few large fish. The collapse of the fishery forced blue pike fishermen either to fish for less valuable species or to discontinue operation.

Middle Devonian rocks are thicker and cover a greater area.
\n
Both Early and Middle Devonian corals are more similar to western European species than they are to presumably contemporary forms from western North America, although some of the eastern faunas contain a significant portion of endemic genera. The general outline of an eastern province was inherited from the Silurian, but disappeared by Late Devonian time when the worldwide Frasnian fauna invaded the area.
A reef fauna of middle Helderberg age is known from the northeast part of the province and is composed of both endemic and widespread genera. Approximately contemporaneous off-reef deposits have few species, but these are common in argillaceous rocks of a somewhat larger area.
Rocks of middle Onesquethaw (Schoharie) age, although thin and discintinuous, include the largest and most widespread Early-Devonian coral fauna. Endemic genera are numerous but other elements are widespread and some species are apparently ancestral to species in the succeeding Onondaga fauna.
The late Onesquethaw (Onondaga) faunas are the largest and most widely distributed of all those under review. Succeeding faunas of the Cazenovia, Tioughnioga and Taghanic Stage (Hamilton-Tully sequence) are less widespread and are clearly derivatives of the late Onesquethaw fauna. The Taghanic fauna is the latest Middle Devonian rugose coral fauna in the area
A number of iron meteorites contain elongated inclusions consisting predominantly of troilite, which have been termed Reichenbach lamellae. Two types of inclusions exist, the first up to 6 cm long and 0·2 mm wide, the second up to 2 cm long and 3 mm wide. The first type contains troilite with subordinate daubreelite and is commonly rimmed by schreibersite and swathing kamacite; the second consists largely of troilite with daubreelite and rare graphite and silicate grains.
Both types formed from a residual sulfide melt after the solidification of NiFe metal. Swatching kamacite surrounding troilite in iron meteorites formed by nucleation at the troilite-metal interface during the formation of the Widmanstätten texture.
Meteorites containing troilite inclusions of the second type appear to have cooled more rapidly than most iron meteorites.
In view of the confusion surrounding the use of the term Reichenbach lamella, it is suggested that the term be dropped from the literature.

The nearly complete Devonian sequence in New York has been established as the North American standard of reference.
\nThe structural belt that includes unmetamorphosed Devonian geosynclinal strata is bonded on the southeast and east by metamorphic and igneous rocks of the Blue Ridge and Piedmont provinces. Some meta-sedimentary and igneous rocks of the Piedmont may be Devonian, but the only rocks known to be of this age southeast of the structural belt are mudstones and siltstones in the subsurface of northwest Florida and adjacent Georgia.
\nThe three oldest stages of the Devonian in the Appalachian area — Helderberg, Deerpark, and Onesquethaw— consist (in ascending order) of carbonate, clastic, and carbonate rocks across an increasingly broad area. The rock units are thin, and facies relations are complex. Most units appear to have accumulated on a relatively stable base in medium- to high-energy environments.
\nSignificant subsidence began in Onesquethaw time and continued into the Carboniferous. Concurrently uplifted source areas to the east shed vast amounts of detritus, most of which was trapped in the trough. Middle and Upper Devonian strata are dominantly shallow-marine, fine-grained clastic rocks. These reach a maximum thickness of over 11,000 feet in eastern Pennsylvania.
\nMiddle Devonian terrestrial rocks occur locally on the east side of the structural belt. By the close of the Devonian they had spread widely over the northern half of the geosyncline.
\nOn the craton, the Middle and Upper Devonian rocks are limestones and shales, but units are thin and discontinuous except for black shale, which, over broad areas, is the latest Devonian deposit. Deposition of this shale persisted into post-Devonian times.

Comparison of the results with ‘blank’ and dosed analyses shows that radiogenic 40Ar was detected and was measured to within a factor of two or better. The estimated standard deviation of precision is 12% for analyses containing 5% or more radiogenic 40Ar. A statistical analysis suggests that real differences in apparent age were detected between three of the analyzed domes. The ages, which range from 6400 to 10,200 years for experiments with 5% or more radiogenic 40Ar, are, in general, consistent with ionium ages on 5 of the same samples and with glacial and 14C evidence of age. They suggest that most of the Mono Craters volcanos are on the order of 10,000 years old or less. The results also suggest that the problem of excess 40Ar may not be severe for KAr dating of volcanic rocks.
An analysis of data on hydraulic parameters collected during a single boat trip down a river system is presented, plotted in form of the hydraulic geometry. A dimensionless rating curve is used to estimate bankfull and average discharge for basins of various sizes. When compared with gaging station data, estimates of bankfull discharge are as consistent and possibly equal in accuracy to estimates made from gaging station data. Estimates of average discharge are less consistent; within the range of drainage areas represented by the gaging stations, errors of estimate vary from 0 to 58 percent. Local variations of bed material size along the river are compensated mostly by changes in local channel slope and roughness and do not much affect the progressive downstream changes in width, depth, or velocity.

Complete conventional, rapid rock, and spectrochemical analyses by the U.S. Geological Survey are reported for a granite (replacement for G-1), a granodiorite, an andesite, a peridotite, a dunite, and a basalt. Analyses of variance for nickel, chromium, copper, and zirconium in each rock sample showed that for these elements, the rocks can be considered homogeneous. Spectrochemical estimates are given for the nickel, chromium, copper, and zirconium contents of the samples. The petrography of five of the six rocks is described and CIPW norms are presented.
A classification of the craters photographed by the Ranger VIII and IX missions into four categories according to relative sharpness shows that at diameters of 100 meters, the predominant craters have broad rims and low depth-diameter ratios and are partly covered with smaller craters which generally have sharper rims and higher depth-diameter ratios but include all classes. If competing processes of crater formation and destruction are responsible for the mix of crater types observed, an abrupt increase in the proportion of sharp craters suggests an intense episode of crater destruction to produce a smoothed surface that was subsequently recratered. Data comparable to those presented can readily be obtained from Lunar Orbiter photographs to determine if an increase in the proportion of sharp craters is present over more extensive areas and to test various cratering histories that may account for it.

Chloride solutions and muscovite-bearing assemblages characteristic of hydrothermal wall-rock alteration were used; weak acidities at temperature were therefore involved. The metal concentrations encountered tended to be higher than those observed in high bisulfide-H2S systems at neutral to weakly basic pH used in most previous experimentation; the chemical conditions of the work, although not completely satisfactory, are geologically more realistic than previous experimentation done in the basic-pH region.
Carbon unusually rich in C13(δC13 = +5.4 to +19.0 per mil relative to the Peedee belemnite carbonate standard of the University of Chicago) is characteristic of certain diagenetic limestones and dolomites in the Miocene Monterey Shale of California and the Nye Mudstone of Oregon. This heavy carbon may have originated through low-temperature equilibration between CO3- - and CO2 in migrating carbonated waters or between CH4 and CO2 in natural gas. Light carbon (δC13 = -5.6 to -18.2 per mil) derived through nonequilibrium oxidation of organic matter also occurs in the carbonate of Monterey Shale in some localities, but at most places it is much less common than heavy carbon.
The chemical compound 3-trifluoromethyl-4-nitrophenol (TFM) is used to control the sea lamprey (Petromyzon marinus) in the upper Great Lakes. It is introduced into streams in which sea lampreys have spawned, to kill the larvae. These 'treatments' are carried out at intervals shorter than the larval phase of the sea lamprey's life cycle (about 4 to 7 years) to prevent movement of the metamorphosed parasitic lampreys into the lakes. Most of the streams which contain sea lamprey larvae also have valuable resident fish or serve as spawning and nursery areas for fish of the Great Lakes. These species must be protected from both the direct toxic effects of the control method and from indirect effects such as destruction of food supplies. Studies have shown that TFM is nontoxic to most species of fish when used at the concentrations that kill larval lampreys. Information on the effect of TFM on aquatic invertebrates is meager. Applegate et al. reported that TFM was not harmful to selected invertebrates which they included in simulated stream tests. They also stated that no harmful effects to invertebrates were observed during actual stream application. The variety of invertebrate species used in simulated stream tests was limited, and close observation of invertebrates under stream conditions is difficult. Therefore, the present laboratory bioassays were conducted to determine the toxicity of TFM to representatives of a number of groups of invertebrates.

Experimental results show that intense ultraviolet radiation reacts with the constituents of the Jovian atmosphere to produce C2H4, C2H6, C3H8, and higher polymers. The general procedure for calculating both equilibrium and nonequilibrium abundances of these products is formulated and applied to the case of the surface passage of a satellite shadow. A specific example is made of ethylene, for which an analytical approximation gives 1010 molecules in an atmospheric column of 1 cm2 cross section after a very rapid rise to equilibrium. Such a concentration of ethylene does not substantially affect the infrared radiation in the shadow.

Physiographically, the area is marked by steep slopes of silty carbonate sediment and precipitous rock cliffs dusted by carbonate debris. Three rocks, obtained from the lower and middle side of the canyon (914–1676 m depth), are late Miocene-early Pliocene to late Pleistocene-Recent in age; all are deep-water pelagic limestones. They show (i) that the Tongue of the Ocean has been a deep-water area at least back into the Miocene, and (ii) that much shallow-water detritus has been swept off neighbouring banks to be incorporated with the deep-water fauna in the sediment.

From 1460 to 1310 meters the sidewall is covered by unconsolidated sediment lying at 35° to 40° from the horizontal. An outcrop of Pleistocene or younger sediment at 1460 meters is probably a remnant of a former fill.
