    STATISTICAL BASIS FOR CYCLOTHEMS: A QUANTITATIVE STUDY OF THE SEDIMENTARY SUCCESSION IN THE EAST PENNINE COALFIELD (1962)
    Oxford, UK : Blackwell Publishing Ltd
    Sedimentology 1 (1962), S. 0

    Thema: Geologie und Paläontologie
    Notizen: Study of cyclic sedimentation in the Coal Measures is impeded by confused terminology and ideas. It is suggested that the first steps in the investigation of an area or sequence where cyclic sedimentation is suspected should be:(1) to determine statistically if a modal cycle is present and to define that cycle,(2) to erect a composite sequence representative of the succession.The Coal Measures of the East Pennine (Yorkshire-Derbyshire-Nottinghamshire) Coalfield. England, are examined to illustrate the application of this idea. The succession shows a modal cycle of non-marine shale followed upwards by seat-earth with secondary modes (also non-marine sediments) made up of shale—siltstone—shale—seat-earth and shale—siltstone and sandstone—shale—seat-earth. The composite sequence for the whole succession is marine shale—non-marine shale—siltstone and sandstone—non-marine shale—seat-earth.Consideration of cycle types, horizontal and vertical variation and thickness, lead to the suggestion that sedimentational controls played the major part in the development of the cyclic succession in the Coal Measures of the East Pennine Coalfield. Only three horizons are exceptional and suggest the possibility of regional diastrophic controls or world-wide changes of sea level.

    RECENT SEDIMENTARY HISTORY OF ST. JOSEPH BAY, FLORIDA (1962)
    Oxford, UK : Blackwell Publishing Ltd
    Sedimentology 1 (1962), S. 0 
    Details
    ISSN: 1365-3091
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Geologie und Paläontologie
    Notizen: The history of St. Joseph Bay, on the west coast of Florida, begins with the last rise in sea level about 5,000 years ago. The formation of an extensive cuspate spit has formed a basin which is now in the process of being filled by detrital sands delivered via longshore drift from the eastern Apalachicola River. Prior to or during early stages of spit development, a wedge of fine material was deposited over the old terrace surface from an old distributary of the Apalachicola. Present sedimentation has as yet failed to obscure portions of this older surface within the lagoon.Clean quartz sand and biological carbonates comprise the bulk of the present sediment contribution. The typical East Gulf “kyanite-staurolite” heavy mineral suite is present, as is the kaolinite-montmorillonite-illite clay mineral suite common to this coast.Sediments in this area have an average organic content of about 1.4%. A high organic carbon/organic nitrogen average of 15.4 has resulted from the accumulation of highly carbonaceo us plant debris under the restrictive environment of the lagoon.

    MINOR STRUCTURES OF UNCONSOLIDATED MARINE SEDIMENTS REVEALED BY X-RADIOGRAPHY (1962)
    Oxford, UK : Blackwell Publishing Ltd
    Sedimentology 1 (1962), S. 0 
    Details
    ISSN: 1365-3091
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Geologie und Paläontologie
    Notizen: Hamblin's (1962) X-radiographic technique for examining the minor structures of sandstone and siltstone is applied to the study of structures in cores of unconsolidated sediments. The technique is capable of revealing particles not visible on the surface of the core, of resolving structures poorly defined in reflected light, and of revealing latent structures in apparently homogeneous sediments.

    THERMODYNAMIC STUDIES ON DOLOMITE FORMATION AND THEIR GEOLOGIC IMPLICATIONS: AN INTERIM REPORT (1962)
    Oxford, UK : Blackwell Publishing Ltd
    Sedimentology 1 (1962), S. 0 
    Details
    ISSN: 1365-3091
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Geologie und Paläontologie
    Notizen: Many theories have been advanced for the origin of sedimentary dolomites. Yet some of these theories are chemically and thermodynamically unsound. The present paper is an interim report on the study of thermodynamics (and chemistry) of dolomite formation. It is hoped that this and other similar papers on chemistry and thermodynamics of dolomite formation will prevent the perpetuation of unsound and untenable theories in the geological literature.

    THE FREE ENERGY OF THE FORMATION OF DOLOMITE FROM ITS CARBONATE COMPONENTS (1962)
    Oxford, UK : Blackwell Publishing Ltd
    Sedimentology 1 (1962), S. 0 
    Details
    ISSN: 1365-3091

    Thema: Geologie und Paläontologie
    Notizen: Three methods for the determination of the free energy A F, of the reaction, 〈displayedItem type="mathematics" xml:id="mu1" numbered="no"〉〈mediaResource alt="image" href="urn:x-wiley:00370746:SED191:SED_191_mu1"/〉 are discussed: the method of two triple points, that of combining solubility products and that of combining dissociation pressure curves.The first method, although thermodynamically well founded, fails by irreversibility, and by the third method data of sufficient accuracy are unlikely.The solubility products (L) necessary for the second method may be derived either from solubility or from pH measurements, the results being in good agreement. For dolomite, L25D= (1.26 ± 0.24) · 10-17 is the average of values from the experiments described in this paper and these of Kramer (1959). The mean value obtained from the solubility and the pH data is Δ F1°= 1720 ± 280 cal.; for LM25 the two values 3.43 · 1.3 · and 1.3 · 10-7 have been found in both ways.

    EVAPORITE TYPE DOLOMITE IN SALT FLATS OF WESTERN UTAH (1962)
    Oxford, UK : Blackwell Publishing Ltd
    Sedimentology 1 (1962), S. 0 
    Details
    ISSN: 1365-3091
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Geologie und Paläontologie
    Notizen: Beds of fairly pure to impure dolomite, varying in thickness from 1 mm to 1 ft., occur widely throughout a large part of the Salt Flats of the Great Salt Lake Desert in Western Utah. Most of the sediments studied evidently formed within the past few tens of thousands of years (as dated by C14 methods), during late Lake Bonneville and Recent time. Alternating dark and light layers of dolomite, carbonate-bearing clays, and clays make up the upper few feet of sediment that was sampled. Dark layers however, are significantly higher in silicates plus SiO2, content and have approximately twice as much Mg2+ as the light layers. The writers suggest that the process of dolomite-formation was hastened by elevated temperatures, occasioned by solar absorption through a saltcrust “window” over the salt pans. Results of this study indicate that the dolomite is possibly of secondary origin (replacement type). Enough information is not available at this time in order to determine the duration of diagenetic dolomitization in terms of days, weeks or years, nor is it known if the diagenetic alteration of calcite to dolomite occurred at the sediment-water interface or after burial (or both at different times).

    SOME MIDDLE SILURIAN REEFS OF GOTLAND (1962)
    Oxford, UK : Blackwell Publishing Ltd
    Sedimentology 1 (1962), S. 0 
    Details
    ISSN: 1365-3091
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Geologie und Paläontologie
    Notizen: A number of illustrations are presented, which show some characteristics of the reefs occurring in the Upper Visby and Hogklint Beds of Gotland. These series should probably be correlated with the uppermost Llandoverian and Lower Wenlockian. Reef growth took place as the water became progressively shallower. There are no reefs in the lower part of the Upper Visby Beds, which consist of marl with limestone Ienses, and was formed in relatively deep water. No reefs occur in the uppermost Hogklint, which consists of an algal limestone formed in very shallow water.

    THE STRUCTURE OF SEDIMENTARY DEPOSITS OF BRAIDED RIVERS (1962)
    Oxford, UK : Blackwell Publishing Ltd
    Sedimentology 1 (1962), S. 0 
    Details
    ISSN: 1365-3091
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Geologie und Paläontologie
    Notizen: A description is given of the sedimentary structures and pebble orientations of two braided rivers, the Durance and Ardkhe, whose origin, hydrology, mineralogy, and mechanical composition are already well known.Microtopographic measurements indicate uneven bedding planes. Macrostructures of the deposits show many channel or festoon laminations alternating with bar deposits, showing parallel bedding or oblique, foreset laminations.Oblique laminations (foreset lamination) occur mainly at the downstream ends of the bars along the upstream side of steep concave banks of channels running obliquely to the general valley trend.Pebbles, gravel, and coarse sand dominate over silty deposits which occur as the top layer of the flood plain and occasionally as channel fill. These silty deposits (loams) are very sandy and contain many irregular current ripple marks, distinguishing them from the heavy clay deposits of the flood plain of meandering rivers.Graded bedding is rare. Structures resembling the flute casts and load casts of turbidity currents have been observed but are uncommon. Irregular current ripple marks of horseshoe shape and erosion flow marks parallel to the current direction are common.The average orientation of the long axis of cobbles, pebbles, and coarse sand grains is normal to the current direction. The inclination of flat pebbles is upstream. Points aiding in discrimination between deposits of braided rivers and of turbidity currents are given in Table II.
