    Description / Table of Contents: Summary The author who for over 30 years has studied deep-sea sediments and especially the Red clay has, especially on basis of results from the Swedish Deep-Sea Expedition with the “Albatross”, arrived at the conviction that the current explanation for the disappearance of the lime leading to the formation of Red clay is not sufficient. The formation of Red clay during Tertiary time cannot be ascribed to the action of cold Antarctic and Arctic bottom currents, which must have been very feeble or missing, when there were no polar ice-caps and the bottom temperature of the oceans was about 8° to 10° higher than at present. A principal lime-dissolving agency, responsible for the formation of Red clay are “magmatic volatiles”, i.e. carbon dioxide, hydrochloric acid etc., released at submarine volcanic eruptions or at the extrusion of subcrustal matter, leading to the formation of the Madatlantic Ridge and other submarine ridges.
    Abstract: Résumé L'auteur qui, depuis plus de 30 années, étudie les sédiments abyssaux et, en particulier, les argiles rouges, est convaincu, et cela notamment depuis l'expédition océanographique suédoise de «Albatross», que l'explication courante de la disparition du calcaire qui conduit à la formation de cette argile n'est pas suffisante. Pendant la période tertiaire, on ne peut pas en attribuer la formation à l'action, de courants très froids arctiques et antarctiques parcourant le fonds des océans, car ceux-ci durent être très faibles, voire inexistants si l'on admet que les calottes glaciaires des pôles n'existaient pas et que la température abyssale était supérieure de 8° à 10° C à celle d'aujourd'hui. Le principal agent solvant du calcaire à l'origine des argiles rouges doit être reconnu dans certaines volatilisations du magma, tels le dioxyde de carbone et l'acide chlorhydrique par exemple. Celles-ci doivent avoir été provoquées par des éruptions volcaniques sous-marines ou par des extrusions de matériaux volcaniques qui ont conduit à la formation de nombreuses chaînes de montagnes sous-marines comme par exemple celle du centre de l'Atlantique.
    Notes: Zusammenfassung Der Verfasser, der seit mehr als 30 Jahren die Tiefseesedimente und insbesondere den Roten Ton untersucht, ist namentlich auf Grund der Ergebnisse der Schwedischen Tiefsee-Expedition mit der „Albatross” zur Überzeugung gelangt, daß die landläufige Erklärung für das Verschwinden des Kalks, dank dessen es zur Bildung des Roten Tones kommt, nicht genügt. Die Bildung desselben während des Tertiärs darf nicht der Wirkung kalter antarktischer und arktischer Grundströmungen zugeschrieben werden; diese werden im Gegenteil sehr schwach gewesen sein oder gar nicht existiert haben, da es damals keine polaren Eiskappen gab und die Bodentemperatur der Ozeane um 8 bis 10° C höher war als heute. Viel eher kommen für die Bildung des Roten, Tones magmatische Gase wie CO2, HCl usw. als wichtigste Kalklöser in Betracht, die zu der Zeit ausgeworfen wurden, als submarine Vulkanausbrüche oder Extrusionen von Tiefenmaterial zur Bildung des mittelatlantischen Rückens und anderer submariner Gebirgszüge geführt haben.

    Notes: Abstract The internal conversion spectrum following the decay of193Au has been studied in the electron energy region 0.8 to 700 keV, with the use of high-resolution magnetic beta-ray spectrometers. Several not previously reported transitions have been estabblished. Multipolarities and mixing ratios have been deduced fromK/L and subshell intensity ratios, and the majority of the transitions were found to be ofM1 and/orE2 characters. A revised level scheme for193Pt, which consistently accomodates most transitions, has been constructed. Tentative spin-parity values have been assigned to all levels.

    Notes: Abstract An electron-electron coincidence method for precise measurements of internal conversion probabilities is described. By usingK-Auger electrons the atom itself provides a unity standard in the same nuclear decay. The method is applied to the decay of111In in which theK-conversion probability of the 245 keV transition is determined to be 0.0494±0.0011. Relative internal conversion intensities and transition energies are determined using a double focussing spectrometer. These data make it possible to calculate conversion coefficients for all electron shells.
