Graptolites collected from the uppermost part of the Martinsburg Formation (Pen Argyl Member) at and near the contact with the overlying Shawangunk Formation at Lehigh Gap, Pa., indicate that the uppermost Martinsburg is as young as Edenian to early Maysvillian (upper subzone [Climacograptus spiniferus subzone] of zone 13 | Orthograptus truncatus intermedius zone]). The Martinsburg gradationally overlies the Jacksonburg Limestone of late Middle Ordovician age, suggesting a lower age limit for the Martinsburg.

The granitic parts of the complex have Rb-Sr ages of about 2.5 b.y. and are classed as of Precambrian W age. The rocks are divided into two major units: (1.) Bell Creek Gneiss consisting mostly of coarse megacrystic granitic rocks and lesser amounts of mafic gneiss and metasedimentary rocks in layers concordant to the foliation of the granitic gneiss, and (2) Compeau Creek Gneiss, previously described to the east, which is mostly medium-grained granitic gneiss and lesser amounts of massive granitic rocks and locally abundant xenoliths of mafic and metasedimentary rocks. Compeau Creek Gneiss intrudes Bell Creek Gneiss throughout the area. Mafic and metasedimentary rocks in the Bell Creek Gneiss are interpreted as remnants of a greenstone belt. The granitic parts of the Bell Creek Gneiss are of problematic origin. Their
composition suggests a magmatic origin, but they do not intrude any rocks with which they are in contact; they form concordant layers in all
observed places. Granitic parts of the Compeau Creek Gneiss are suspected to be highly altered and partly melted sedimentary rocks.
The mafic parts are probably xenoliths of mafic rocks from the Bell Creek Gneiss.
Quantitative electron microprobe analyses of biotite grains for iron, magnesium, and titanium from tuff beds in the lacustrine
Green River Formation (Eocene) of Colorado and Utah provide a tentative method of identification and a permissive stratigraphic correlation of tuffs. Tuff beds that have been identified and correlated by stratigraphic means were sampled at five localities in Colorado and Utah to determine if microprobe analyses of biotite could be used as a method of correlation. Although most of the original phenocrysts and
glass shards of these pyroclastic beds have undergone extensive postdepositional alteration, biotite seems to have been unaffected. The
iron, magnesium, and titanium contents of the biotite do not uniquely characterize individual tuff beds, but when the proportions of these
elements are compared in a continuous stratigraphic sequence of beds, correlation of individual tuffs or groups of tuffs is possible over areas
exceeding several hundred square miles. The method may be used for detailed correlation of pyroclastic beds where stratigraphic, faunal, and radiometric methods have been unsatisfactory.
Humic acids, the most abundant organic components of natural water systems, are complex mixtures of molecular aggregates of different chemical and physical properties. 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.
The variation in solvent composition of a mixed solvent used in Soxhlet extraction of sediments has apparently often been overlooked. Owing to azeotropic distillation of the solvent introduced into the apparatus, care must be taken to determine the composition of the solvent actually doing the extracting.

Within the Park City Group (Permian), the Plymton Formation, overlying the Kaibab Limestone, is divided informally into five parts. The uppermost Plympton has yielded silicified fossils. The faunule studied is characterized by the scaphopod Plagioglypta and by bellerophontacean and neritacean gastropods, suggestive of a middle Permian age. Specimens are worn, and several lines of evidence suggest that this is a high-energy beach deposit associated with a residual high. The interpretation supplements the field evidence of a hiatus between the Plympton and the overlying Gerster Formation. Other occurrences of elements of the faunule in the equivalent Phosphoria rock complex are noted, but only a few were probably deposited in a high-energy beach environment.

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.
New magnetization data for Late Cretaceous glassy welded tuffs, volcanic breccias, and altered basalts from the Elkhorn Mountains volcanic field, together with geologic, mineralogic, and K-Ar data, indicate that (1) the glassy tuffs have unusually strong, uniform remanent magnetizations which are reversely polarized, much of the remanence perhaps residing in submicroscopic single-domain iron oxide particles within the glass itself, (2) breccias emplaced at minimum temperatures of about 400°C have moderately dispersed remanent magnetization directions which are normally polarized, and (3) basalts that occur within a broad area of hydrothermal alteration have remanent magnetization directions which are normally, horizontally, and reversely polarized. Present and previous studies indicate the occurrence of from two to eight complete field reversal cycles during emplacement of the volcanic field about 78 m.y. ago. Among the rocks

Recently completed fission-track and K-Ar dating of zircon, sphene, apatite, muscovite, biotite, and hornblende indicate that the Clayton Peak stock was intruded 37-41 m.y. ago, the Alta stock about 32-33 m.y. ago, and the Little Cottonwood stock between 24 and 31 m.y. ago. Pb-a ages on zircon, though showing the same sequence, are about twice as great and are inferred to represent a partial
mixing of inherited Precambrian zircons. Acceptance of a middle Tertiary age for the Little Cottonwood stock requires revision of earlier
interpretations that it could be as old as Late Cretaceous. K-Ar dates also indicate that the Keetley Volcanics are 32 to 35 m.y. old, and a
single date of 37.3 m.y. was obtained on the Traverse Volcanics, suggesting that they are more closely related to volcanic activity in the
adjoining Oquirrh Mountains.
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.

Moreover, the geometry of such a photograph provides the same angular measurements between objects as can be made with a transit. A measurement of distance on a single photograph, however, requires control points. These can be surveyed at any convenient time, not necessarily when the initial photograph is made. Distances can also be determined by simple stereophotography from a base line of suitable length.

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.

Time-drawdown data measured at 17 observation wells during a 3.5-day aquifer test define an average apparent specific yield of 0.13. Soil-moisture-content data measured at nine access holes during the aquifer test indicate that complete gravity drainage had not been attained in the cone of depression by the end of the drawdown period. The moisture-content data were therefore extrapolated with time to define an average specific yield in the range 0.13 to 0.15. The results obtained by the two methods arc in close agreement. However, the significantly lower standard deviation of the results from the moisture-content analysis indicates that extrapolation of the apparent values derived by this method may provide a more reliable estimate of the true specific yield than the apparent values derived by the time-drawdown method. Reliable estimates of specific yield in the zone of seasonal water-level fluctuations are also possible from an evaluation of the soil-moisture change in the spring and summer recession period.

A complete chemical analysis is given for one. In the Snake Creek-Williams Canyon
outcrop area, where the hybrid rocks grade from granodiorite with 63 percent SiO2 to a quartz monzonite with 76 percent SiO2 within a
horizontal distance of about 3 miles, abundance and crystal habit of the apatite change with rock chemistry. The apatite probably is slightly
more than 90 mole percent fluorapatite in the most felsic rocks, slightly less in the most mafic. The range of F->OH substitution in apatite from this outcrop area is much smaller than in the coexisting biotites. Except for manganese, strontium, sodium, and the rare earths, there is very limited substitution for calcium in the crystal structure of these apatites. Apatites from the more mafic rocks tend to contain a lighter,
more basic assemblage of rare earths, in agreement with results obtained for coexisting allanites, monazites, and zircons.
Phyllite and marble dredged from the lower part of the continental slope between Cuba and the Yucatan Peninsula seem to support the contention that a pre-early Tertiary metamorphic belt extends from the western Greater Antilles into northern Central America. The minimum K-Ar ages derived from the samples suggest that the metamorphic event was pre-Late Cretaceous, and evaluation of the K-Ar data implies that this metamorphic event is not older than Late Jurassic. Greater antiquity, however, is inferred from structural and stratigraphic relations in British Honduras, where the latest regional metamorphic event was post-Early Permian and pre-Middle Jurassic. Rifting and extension related to plate motions along the British Honduras Quintana Roo margin through Mesozoic and earliest Cenozoic time presumably would preclude extensive regional metamorphism, permitting only limited development of schistose rocks there during that interval. The timing of metamorphic events in western Cuba is uncertain, but a pre-Middle Jurassic episode possibly is reflected in the phyllite and marble terranes of Isla de Pinos and Sierra de Trinidad. Local incipient metamorphism of Early and Middle Jurassic strata in the Sierra de los Organos may have resulted from severe tectonism that began in Late Cretaceous time and diminished in the Eocene.

Packer seats were poor in the uncased part of the hole because of unstable wall conditions, and leakage around packers occurred during some tests. However, leakage generally was slight, as shown on pressure-gage charts, and had little effect on the tests. The static water levels in the intervals tested ranged from 31.6 meters (104 feet) below land surface in the upper interval tested to about 115 meters (377 feet) below land surface in the lower interval tested, indicating decreasing head with depth. The relative specific capacities of isolated zones ranged from less than 0.001 cubic meter per day per meter (less than 0.001 gallon per minute per foot) of drawdown to 0.898 cubic meter per day per meter (0.050 gallon per minute per foot) of drawdown.
