Preliminary field tests of an active ultraviolet imaging system have shown that it is possible to produce linages of the terrain from distances as great as 75 feet by means of reflected ultraviolet light at wavelengths longer than 3300 A. Minerals that luminesce when exposed to ultraviolet energy have been detected from distances as great as 200 feet. With appropriate design modifications, it may be possible to utilize a similar system in detecting luminescing minerals from greater distances. Also, with a similar system and appropriate auxiliary equipment such as image intensifiers, it may be possible to discriminate between naturally occurring materials on the basis of reflected ultraviolet energy at wavelengths shorter than 3000 A. In this part of the spectrum image contrast for some rock types may exceed that from visible light. Information from these and related ultraviolet spectralanalysis studies may be useful in evaluating data obtained from passive ultraviolet systems in lunar orbit as well as from active systems on the lunar surface.

Most of the alternative explanations recognize a décollement to some extent, but attribute it to movement of the basement beneath. Surface and subsurface data are here reviewed to show that the Jura deformation was produced in a gliding sheet, in which the forces of gravity and inertia were generated within the total moving mass. Features of the folded Jura which support the décollement hypothesis are: (1) Nowhere are rocks older than Middle Triassic exposed, which strongly suggests that the folding does not extend to the older rocks. (2) Subsurface data in the Lons-le-Saunier region clearly show that the external border of the Jura has moved northwestward over the eastern margin of the Bresse Basin. (3) Lower Jurassic rocks rest on Upper Jurassic along a horizontal fault 1234 m deep in the Risoux well near the middle of the Jura. (4) The tabular areas, with their absence of folds, are expectable in a décollement. (5) High-angle tear faults, interpreted as not extending into the basement, are normal features of a décollement sheet. A continuous décollement around the southwestern end of the Swiss Plain can reasonably be inferred, connecting the internal Jura, the Salève, and the Subalpine folds as part of the décollement mass. Elsewhere, the internal border of décollement extends southeastward into the Molasse basin for an unknown distance and probably underlies the entire basin; if it does, a causal relation to the Alps is indicated. © 1966, The Geological Society of America, Inc.

After a search of some 40 years, four lakes have been found that are producing a kind of organic ooze judged to be a modern analogue of the precursors of rich oil shale. Two of the lakes are in central Africa and two are in Florida. All four are shallow. The ooze in all four is predominantly algal, entirely in the form of minute fecal pellets, and does not decay in warm, wet, oxidizing environments.
Several of the most unusual, mummified microorganisms found in the oil shale of the Green River are illustrated as testament to the inference that the Eocene organic oozes also were resistant to decay.
Studies to determine why these algal oozes do not decay are in progress, but as yet no satisfactory explanation is available. The ooze from Mud Lake, Florida, contains very few living bacteria but a great many bacterial spores, suggesting some active inhibitor. Gentle and slow anaerobic decay takes place in the ooze 1 foot or more below the mud-water interface.
The algal ooze accumulates slowly. That at a depth of 3 feet below the mud-water interface has a C14 age of 2280 ± 200 years. If compacted, this 3-foot layer would amount to a layer only about 0.5 inch thick.
The air-dried algal mud (from Mud Lake) looks much like oil shale and has a C-H ratio essentially like that of the organic matter in oil shale. The oxygen of the mud, however, is roughly 5 times as high as in oil shale. The calorific value of dried Mud Lake algal ooze is about 6600 cal/g, whereas the organic matter from Green River oil shale averages about 9500 cal/g.
Analyses show that the dried algal ooze from Mud Lake contains small quantities of higher fatty acids (C12–C34), with C16 being dominant. It also contains some unsaturated fatty acids and about 0.3 per cent of n-alkanes, predominantly odd carbons, with C29 being dominant. A few qualitative analyses show that carotenoid pigments and terpenes are also present.
A possible source of hydrocarbons is the long branched side chain of the chlorophyll molecule. Small crustaceans liberate this in the form of phytol, which, by dehydration, can go over into a series of saturated and unsaturated hydrocarbons, including phytanc and pristane, both of which are common in Green River oil shale. Search for other precursors of hydrocarbons continues.

S. Geological Survey and the U. S. Coast and Geodetic Survey. The profiles were flown at 20,000 feet above sea level and cover approximately 1,350,000 square miles of the Arctic Ocean between the North Pole and the North American continent. When the profiles are smoothed to remove crustal anomalies, the resulting contoured values differ from the U. S. Hydrographic Office Chart 1703 N for 1955 corrected to 1951 by as much as 2000 gammas in the northern part of the Arctic Archipelago. A nondipole regional focus east of Greenland has decreased in amplitude but has changed very little in position since 1907.5. There is a profound difference in the magnetic characteristics of the rocks on either side of the underwater Lomonosov Ridge across the Arctic Ocean. In the Eurasian Basin the high-altitude profiles are relatively smooth or show only minor anomalies, but on the North American side of the ridge there is a large area of closely spaced, high-amplitude anomalies which has been designated the Central Magnetic Zone. Although the anomaly trends parallel the Alpha Rise, this zone is far more extensive, including nearly half of the Canadian Basin on one side and probably all the Central Arctic Basin on the other side of the rise. The Lomonosov Ridge is marked by a persistent anomaly of moderate size that indicates the presence of magnetic material in the ridge. Probable block-fault structures along the flanks of the Alpha Rise are associated with blocklike magnetic anomalies of comparable widths. A characteristic magnetic pattern occurs over an area of jagged bottom topography in the Eurasian Basin. A similar magnetic pattern over part of the Lena Trough may indicate another area of jagged topography. The belt of epicenters associated with the Mid-Atlantic Ridge continues through this rugged part of the Eurasian Basin, but the absence of the typical high magnetic anomaly makes it doubtful that the mid-oceanic ridge extends through this part of the Arctic. Magnetic data indicate that the thick sections of sedimentary rocks in the Paleozoic geosynclinal belts of northern Ellesmere Island and northern Greenland continue out under the adjacent continental shelves north of Greenland, west of the Arctic Archipelago, north of the part of Alaska east of Barrow, and under part of the Chukchi Shelf, and that they make up the bulk of the Nansen Swell off Spitsbergen. Thick sedimentary fill is indicated in the magnetically flat areas of the Eurasian Basin next to the Lomonosov Ridge and in the southern part of the Canadian Basin. The magnetic profiles on the Eurasian side of the Lomonosov Ridge closely resemble typical magnetic profiles over both Atlantic and Pacific oceans, where as the profiles of the Central Magnetic Zone on the North American side of the Lomonosov Ridge are completely unlike the oceanic data and show a striking similarity to typical profiles over the Precambrian rocks of the Canadian Shield and its buried equivalent under the Central Stable Region of the United States. Therefore, it is concluded that the Arctic region consists of a probable oceanic area on the Eurasian side and a basin formed by downdropped continental rocks, presumably a Precambrian complex similar to that of the Canadian Shield, on the North American side of the ridge.

A whole-rock Rb-Sr isochron age on the St. Kevin Granite establishes it as 1390 ± 60 m.y. old. Mineral ages on the St. Kevin and numerous other rocks are either about the same as the St. Kevin whole-rock age or younger by as much as 200 m.y., even where the relative age is known to be older. Some minor Precambrian intrusive masses that are probably younger than St. Kevin Granite yield mica ages within analytical error of the St. Kevin age, indicating that these rocks can be younger than the granite by only a few tens of millions of years. The mica ages, both Rb-Sr and K-Ar, are thought to be minimal, but a K-Ar age of 2020 m.y. on horn-blende probably reflects excess argon. Mica ages from all rocks known geologically to be older than St. Kevin Granite are low and are interpreted as heating ages reflecting intrusion of the granite, in some cases modified further by heating during Laramide time. In this area, Precambrian intrusion and deformation had largely ended by 1200 or 1300 m.y. ago. Plutonism, represented here by the St. Kevin Granite and elsewhere by the Silver Plume and other granites, probably accounts for the numerous mineral ages of about 1300 m.y. previously reported from Colorado although weak regional metamorphism may also have been a factor.

So that the negotiating officials could allocate the water equitably, the amount of streamflow depletion caused by ground‐water withdrawals upgradient from the State line needed to be determined. At the request of the Nebraska officials, the U. S. Geological Survey constructed an electric analog model which could be used to determine the amount of streamflow depletion expected to occur in the next 60 years. The model simulates hydraulic conditions in an area of 7,400 square miles which includes the entire area drained by the Big and Little Blue Rivers in Nebraska. The trans‐missibility of the aquifer (Pleistocene in age) ranges from less than 1,000 to as much as 300,000 gallons per day per foot, and the storage coefficient averages about 0.20. The transmissibility values are based on examination of test‐ hole samples from more than 400 test holes in and adjacent to the basin. Analysis of the model indicates that predicted maximum ground‐water withdrawals between 1962 and 2022 will not deplete the base flow of the Big or Little Blue Rivers by more than 5 percent.

In the past year a number of computer programs in FORTRAN IV have been developed by Charles O. Morgan and Jesse M. McNellis using an IBM-7040 computer to store, retrieve, and manipulate water-quality data. These programs:
(1) Tabulate data at the rate of 40 chemical analyses of water per minute in a format similar to that found in the Kansas ground-water publications.
(2) Perform necessary calculations and print Stiff diagrams at the rate of 30 per minute.
(3) Perform necessary calculations and print Piper diagrams, including a square modification of the normally diamond-shaped cation-anion diagram, and trilinear diagrams of the cations and anions. The symbol representing the analyses located on the diagrams can be designated by either an analysis number or a geologic unit number. A cation-anion diagram showing the average chemical composition of water for an aquifer can also be printed. These diagrams for 50 analyses can be produced in 1.5 minutes.
(4) Plot maps of 42 individual, combined, or calculated parameters obtained from the data cards. These maps can be plotted to any specified scale and for as many as 10 designated geologic units. Computer time involved for one map with 50 plotted points is 15 seconds.
It is estimated that the use of these programs will save several man-months during a ground-water study, and the error inherent in the manual manipulation of data is greatly reduced. The present cost for running 50 analyses through the four water-quality programs on the computer is approximately $20.

Before 1930, students of the stratified deposits of manganese minerals have generally concluded that the contained manganese was derived from the decomposition of the rocks that formed the borders of the basins. Only in a few places have geologists recognized that if these rocks were the principal source of the contained manganese the basins should contain also enormous quantities of iron minerals, whereas most of the large deposits of manganese contain little iron. Even though more than 100 years ago some geologists proposed that the iron contained in some deposits of stratified iron minerals was probably derived from hydrothermal waters related to centers of volcanism, not until about 1930 was this source of manganese in similar deposits seriously proposed. This mode of origin was given the name \"volcanogene sedimentaire\" by French geologists working in Morocco. Since then, other names, such as \"exhalative sedimentaire,\" have been used by geologists working in several European districts. Because of the development of new techniques for the study of the chemical and physical features of the minerals, and because close attention to the lithologic environments of the beds is being given more and more during recent years, it has seemed advisable to review the features of stratified deposits of the manganese minerals in many parts of the world and over a wide range in age. This study indicates that at least three sources may have contributed the manganese in the large deposits of iron-free oxides and carbonates: (1) the rocks that form the borders of the basins, either marine or continental; (2) the nearby underlying sediments, largely of igneous origin, decomposed by warm waters largely derived from depth; and (3) waters of hydrothermal origin derived from great depths during epochs of volcanism from which iron minerals with little manganese are deposited in deep zones, then minerals with much iron and more manganese at intermediate depths, and, finally, manganese minerals with little iron near the surface. As the hot waters of many thermal springs contain more manganese than iron, such waters could yield the pure manganese oxides and carbonates found in stratified deposits. Several kinds of evidence indicate that most of the manganese in the large stratified deposits of the oxides and carbonates of manganese in many parts of the world has been derived from hydrothermal waters from depth related to centers of volcanism. Obviously, manganese derived from decay of the rocks on the lands adjacent to large basins-marine and continental -may have been added to that derived from centers of volcanism to form the sedimentary deposits found in the basins.

The main phreatic explosions, which were preceded by ejection of basaltic spatter, opened a new crater 1.5 km long and 0.3 km wide on the southwest side of Volcano Island in Lake Taal. The eruption covered an area of about 60 square kilometers with a blanket of ash more than 25 cm thick and killed approximately 200 persons.
The clouds that formed during the explosive eruption rose to heights of 15 to 20 km and deposited fine ash as far as 80 km west of the vent. At the base of the main explosion column, flat, turbulent clouds spread radially, with hurricane velocity, transporting ash, mud, lapilli and blocks. The horizontally moving, debris-laden clouds, sandblasted trees, coated the blast side of trees and houses with mud, and deposited coarse ejecta with dune-type bedding in a zone roughly 4 km in all directions from the explosion crater.

Two water bearing units of the same hydrologic system have the potential of yielding water to wells: 1) alluvial deposits, possibly as thick as 60 feet and locally containing beds and lenses of gravel 1 to 5 feet thick; and 2) fractured and jointed bedrock, especially where it is overlain by alluvium.
The most productive ground-water areas are expected to be the lower reaches of the larger valleys. Here the alluvial deposits are thickest and the valleys often follow the trace of fault or fracture systems in the bedrock. A potential yield of 195,000 gpd (U.S. gallons per day) is estimated to be available in the Road Bay area, 55,000 gpd in the Long Look area, and 8,000 gpd in the West End area.
Sites are suggested for test and monitoring wells in the lower courses of six of the valleys on the south coast.

Dating of the warm interval is based on eight radiocarbon dates. Although these do not provide tight control for either the beginning or the end, they permit the interpretation that the warm event began at the start of the worldwide, postglacial warming and that it ended at the time of the Anivik Lake glacial readvance in the Brooks Range. If this is correct, the early Recent warm interval and the \"postglacial thermal maximum\" recognized by Livingstone in the Brooks Range were separated by a period of cooler climate. Deposits 7200 and 3600 years old also record moments when the climate was warmer than at present in coastal northwestern Alaska. Although these may record a continuation of the early Recent warm period, it seems more likely that they represent later and separate brief intervals of warmer climate. A postglacial thermal maximum between 6000 and 3000 years ago is recorded by pollen profiles in the Brooks Range, but is not clearly recorded in the coastal areas of northwestern Alaska. We suggest that as sea level rose to near its present position, the accompanying maritime climate lowered summer temperatures in this coastal area during the time at which areas farther inland were experiencing the high temperatures of the postglacial thermal maximum.

Selective activation techniques make it possible to detect some thirty or more elements by irradiating the ground for periods of a few minutes with either 3-MeV or 14-MeV neutrons. The depth of penetration of neutrons, the effect of water content of the soil on neutron moderation, gamma ray attenuation in the soil and other problems are considered.
The analysis shows that, when exploring for most elements of economic interest, the reaction 2H(d,n)3He yielding ∼ 3-MeV neutrons is most practical to produce a relatively uniform flux of neutrons of less than 1 keV to a depth of 19″–20″. Irradiation with high energy neutrons (∼ 14 MeV) can also be used and may be better suited for certain problems. However, due to higher background and lower sensitivity for the heavy minerals, it is not a recommended neutron source for general exploration use.
Preliminary experiments have been made which indicate that neutron activation in situ is feasible for a mineral exploration or qualititative soil analysis.
Theoretical consideration of the charge-transfer mechanism operative in cells with an electrode of a semiconductive binary compound leads to the conclusion that the half-cell potential of such a compound is not only a function of ionic activities in the electrolytic solution, but also a function of the activities of the component elements in the compound phase. The most general form of the electrode equation derived for such a compound with a formula MiXj which dissociates into Mj+ and Xi− ions in aqueous solution is
EMiXj = EMiXj0 +
where
EMiXj0 =
The equation can be modified to other forms. When applied to semiconductive simple binary sulphides, these equations appear to give better descriptions of the observed electrode potentials of such sulphides than any other proposed equations.

During a three-month trial period, 70 million gallons of industrial wastes were successfully injected at moderate pressures into a deep limestone in the westernmost part of Florida. The movement of these wastes is expected to be predominantly southward toward the natural discharge area which is presumed to be far out in the Gulf of Mexico. The limestone lies between two thick beds of clay (aquicludes) and contains 13,000 parts per million salty water. A series of aquifers and aquicludes appear capable of preventing contamination of the overlying fresh-water aquifers.

Major constituents of the average phosphorite are, by weight per cent: SiO2, 11·9; Al2O3, 1·7; Fe2O3,1·1; MgO, 0·3; CaO, 44·0; Na2O, 0·6; K2O, 0·5; total H2O, 2·2; H2O−, 0·6; TiO2, 0·1; P2O5, 30·5; CO2, 2·2; SO3, 1·8; F, 3·1; organic matter, 2·1; and oil, 0·2. Uranium averages 0·009 per cent.
The phosphate mineral is basically apatite, Ca5(PO4)3F, with small but significant and variable substitutions—Na, Sr, U and Th for Ca, and CO3 and SO4 for PO4.
Rare metals not associated with apatite are associated principally with the organic-matter component of the rocks. This group includes As, Ag, Cd, Cr, Cu, Mo, Ni, Sb, Se, V and Zn. Chromium is the most abundant, having a modal abundance of 0·1 per cent and a maximum concentration of 0·3 per cent.
The average phosphorite is composed of approximately 80 per cent apatite, 10 per cent quartz, 5 per cent muscovite-illite, 2 per cent organic matter, 1 per cent dolomite—calcite, 1 per cent iron oxide, and 1 per cent other components. It is texturally a medium-grained pellet phosphorite.
