Resultados indicam um maior engajamento e produção de sentidos por parte dos estudantes, embora dificuldades com o uso dos recursos digitais tenham sido relatadas.
An approach to a quantum-mechanical model for solid solutions
Authors: Cloke Paul L. 
Published: November 2019

Band gaps calculated theoretically by Kunz, De Cicco, and others, using the augmented plane wave approximation to obtain solutions to the Schrödinger equation, are first shown to yield, utilizing the equation proposed by Van Vechten, good estimation (± 10 %) of the enthalpies of formation of the six alkali halides, NaCl, KCl, NaI, NaBr, LiCl, and LiI over the temperature range 298 K to 900 K, taking account of the changes in lattice constant, band gaps, and ionicities as a function of temperature. This result, together with the remarkable success achieved by Van Vechten in estimating enthalpies of formation of numerous semiconductor compounds and predicting phase diagrams in semiconductor alloy systems suggests strongly that the equation is of general validity.
Nevertheless, when applied to the NaCl-KCl system, with the assumption of linear variation of the lattice constants, ionicities, and band gaps between end members, the equation fails to predict the solvus. Because the lattice constants and ionicities must surely vary approximately linearly with composition, large deviations from linearity must be ascribed to the band gaps, a result again in concordance with theoretical and experimental results reported for semiconductor compounds. In this paper these deviations are arbitrarily assumed to be approximately parabolic, first with the parabolic axis oriented perpendicular to the compositional axis, which yields a reasonable fit to the observed solvus, and then with a rotation of about one degree, which yields an exact fit. Ideal entropy of mixing has been assumed, although this seems rather unlikely in view of the large enthalpy of mixing.
As compared to the two parameter Margules equation, which is widely used to model solid solutions in applications to metamorphic petrology, the two band quantum dielectric model predicts activities differing by up to nearly 600 %, depending upon the component and the composition.
Interprétation du spectre infrarouge de variétés isotopiques de pyropes synthétiques
Authors: Cahay René , Tarte Pierre , Fransolet André-Mathieu 
Published: November 2019

3 échantillons de pyrope pur Mg₃Al₂Si₃O₁₂, ²⁶Mg₃Al₂Si₃O₁₂ et Mg₃Al₂³⁰Si₃O₁₂ ont été synthétisés à 1 000 °C et 25 kbar.
Les spectres infrarouges de ces composés montrent que le remplacement isotopique ²⁸Si — ³⁰Si provoque, pour toutes les bandes situées au-dessus de 500 cm⁻¹, un décalage de fréquence significatif, tandis qu'on n'observe, pour ces mêmes bandes, aucune modification liée au remplacement ²⁴Mg — ²⁶Mg : ceci confirme définitivement l'attribution de ces bandes à des vibrations des groupes SiO₄.
En revanche, les bandes observées en dessous de 500 cm⁻¹, subissent un décalage de fréquence, quel que soit le type de remplacement isotopique envisagé. On doit donc, dans ce cas, renoncer à l'hypothèse de vibrations localisées, spécifiques des modes internes des groupes SiO₄ ou des translations des cations Mg²⁺ et considérer l'existence de vibrations complexes auxquelles participent simultanément les tétraèdres SiO₄, les cations Mg²⁺ et aussi probablement Al³⁺.
Le spectre infrarouge du pyrope synthétique se différencie de celui du pyrope naturel par des fréquences légèrement plus élevées et par des bandes plus fines. Ceci est lié à l'accroissement des dimensions de la maille lors de la substitution de Mg par Fe et surtout par Ca dans le pyrope naturel.
On enhanced vector symmetry and homometry in polytype
Authors: Ohsumi Kazumasa , Nowacki Werner 
Published: November 2019

Pour déterminer la symétrie d'un cristal ou une structure cristalline, on utilise généralement la méthode de diffraction. Cependant, les figures de diffraction d'un cristal dépendent plus directement du réseau vectoriel du cristal que de la structure elle-même. Donc, le relèvement de la symétrie vectorielle (l'élévation de la symétrie par diffraction ; Sadanaga et Takeda, 1968) et l'homométrie peuvent être traités de manière presque identique et considérés comme le problème de la correspondance entre une structure cristalline et son réseau vectoriel.
A la suite de l'étude récente déterminant les conditions nécessaires à une structure pour avoir une symétrie vectorielle augmentée (Sadanaga et Ohsumi, 1979), nous développons l'étude des rapports entre un accroissement de la symétrie vectorielle et une homométrie, ce qui conduit, dans le cas d'autohomométrie, à l'existence d'une structure à symétrie vectorielle augmentée ayant un correspondant homométrique.
La recherche d'exemples ayant cette complexité structurale conduit à deux sortes de conditions suffisantes pour qu'un polytype MX — ou MX₂ — ait une symétrie vectorielle accrue et une homométrie, comme le polytype 20 Hq CdI₂ de la littérature.

Published: November 2019

Goethite-coated eluvial (?) and fresh-looking (alluvial ?) Pt-Fe nuggets from Joubdo stream, Birbir River are very variable in external morphology from rounded, flattened to very irregular with sharp projections. Scanning electron microscopy has revealed crystalline details of the Pt-Fe alloys at magnifications not reported previously. The most common Pt-Fe alloy is Pt₃Fe, probably isoferroplatinum, but tulameenite and tetraferroplatinum are also present. A combined electron probe and quantitative optical study has documented an extensive suite of primary inclusions in Pt-Fe alloy matrix : osmium, irarsite, erlichmanite, genkinite (second world occurrence), hollingworthite, laurite, stibiopalladinite, cuprian gold, bornite, chalcopyrite, cubanite, chromite, magnetite, diopside (?), ferroaugite (?), forsterite (?), rhodian « pentlandite » (?), unnamed RhSbS (Raicevic and Cabri, 1976), and unnamed Rh₂S₃ (Begizov et al., 1975). In addition, unnamed minerals reported for the first time include : Pt(Rh, Ir)CuS₄, Rh(Te, Bi)₂, and unidentified anisotropic Fe — Rh — Ni and Fe — Ni — Ir — Rh sulphides.
Genkinite and osmium are the only platinum-group minerals exhibiting alteration to secondary minerals, the latter to an unidentified iridium-rich alteration product.
Discovery of metallic residues of the Rochechouart meteorite in basement rocks
Authors: Horn Wolfgang , El Goresy Ahmed 
Published: November 2019

The Rochechouart structure of Triassic or early Jurassic age is deeply eroded to the level of the crater floor. At Champonger, the crater floor could be recognized by the association of shatter cones in shocked basement rocks overlain by low temperature suevite. Metal veinlets and particles were found to occur in Champonger basement gneisses within shock produced inter- and intragranular microfractures in various minerals.
The metals very probably are condensates of the vaporized impacting projectile and were probably implanted as metal vapor. The condensed metallic vapor was tightly sealed within these fractures. The metals consist of an alloy containing on the average 73 wt. % Fe, 17 wt. % Cr and 8 wt. % Ni. No Mn was found, small amounts of Co may be present. Due to the high Cr content we suggest that the Rochechouart meteorite was a stony and not an iron as previously proposed by Janssens et al. (1977).
New data on chlorine sulfosalts

Published: November 2019

On a fait des études par diffraction de rayons X et d'électrons sur des sulfoantimonites de plomb antérieurement décrits : ardaite naturel du gisement polymétallique de Madjarovo dans la Bulgarie du sud (Breskovska et al., 1979) et phase synthétique A (Bortnikov et al., 1979). Les paramètres de la maille élémentaire des chlorosulfosels étudiés sont égaux (a = 22,09, b = 21,11, c = 8,05 Å, β = 103° 01', Z = 2) ce qui indique une différence structurale essentielle avec la boulangérite, le minerai le plus proche des chlorosulfosels par sa teneur en Pb, Sb, S et par contre une parenté structurale avec les sulfoantimonites moins riches en Pb : playfairite et launayite. Ces derniers ainsi que les chlorosulfoantimonites, outre leurs constituants principaux Pb, Sb, S contiennent des éléments accessoires (Ag dans la playfairite et la launayite, Fe dans la jamesonite). En conclusion on peut dire que la présence des éléments accessoires stabilise la structure playfairite˗launayite dans le système PbS˗Sb₂S₃ tandis que leur absence rend la structure boulangérite et ménéghinite sans Cu plus stable.
The dielectric thermal analysis
Authors: Egerer Frigyes 
Published: November 2019

The variation of polarization and that of dielectric constants of minerals is determined by recrystallization and chemical processes. So if the change of the dielectric constant of a mineral is measured with temperature, the unknown mineral can be identified.
On the basis of the experimental material described in the present paper as well as the standard curves determined on different minerals according to the requirements, the presence of a large number of minerals can be shown in unknown mineral matters.
Evaluation of prograde regional metamorphic conditions : their implications for the heat source and water activity during metamorphism in the Williyama Complex, Broken Hill, Australia
Authors: Phillips G. Neil , Wall Victor J. 
Published: November 2019

The Willyama Complex around Broken Hill shows a NW to SE increase in metamorphic grade from andalusite-muscovite to sillimanite-muscovite, sillimanite-K feldspar and two pyroxene grade. Mineral assemblages in the dominant pelitic and lesser mafic gneisses (andalusite → sillimanite, cummingtonite-plagioclase, cordierite) indicate a low-intermediate pressure metamorphic path ; and by using solid-solid, silicate-based barometers (cordierite-garnet, orthopyroxene-garnet-plagioclase, garnet-plagioclase-sillimanite) pressures of 5-6 kbar are inferred for a large part of the two pyroxene zone including Broken Hill itself. The overall increase in pressure to the SE is accompanied by a small rise in temperature (T from 650 to 800 °C) and a gradual decrease in water activity (from 1.0 to ~ 0.5) above the second sillimanite isograd. A gradual transition from amphibolite to granulite facies conditions is indicated.
The decrease in water activity appears to be related to the onset of partial melting ; i.e. as in situ partial melting proceeds in response to temperature rise, water activity declines. The latter is compatible with increased dilution of an aqueous fluid by another component, perhaps carbon dioxide, or with fluid-absent conditions.
The low-intermediate pressure prograde P-T path and nearly constant pressure retrograde path cannot be explained by a heat source related to tectonic thickening alone and instead an external heat source (perhaps a deep crustal mafic magma) may be required. Such a heat source may have wider applicability to other low-intermediate pressure terrains.
Approche thermodynamique des phénomènes de dissolution. Aspect cinétique en système fermé et comparaison système ouvert˗système fermé dans le cas de l'albite
Authors: Massard Pierre 
Published: November 2019

La dissolution d'un minéral dans une solution altérante est régie par une loi cinétique simple, valable que le système soit ouvert ou fermé (Massard, 1977) :
v = k.A'/T
où v est la cinétique de la dissolution, A' l'affinité chimique de la réaction associée, T la température et k une constante proportionnelle à k₀, paramètre caractéristique du minéral. Cette relation est ici appliquée à l'albite, minéral étudié en système fermé par Lagache (1965) et en système ouvert par nous-mêmes. Ces deux approches expérimentales, qui correspondent à des contraintes et des conditions de T et P différentes, vérifient les prévisions théoriques et conduisent à des estimations de k₀ concordantes sur l'intervalle de température étudié (85 °C à 200 °C). Nous déduisons de ces études une méthode simple de détermination de k₀ en système ouvert.
Analyse géochimique de divers nodules de péridotites en enclaves dans des basaltes alcalins ou des pipes de kimberlites : mise en évidence de leur nature résiduelle
Authors: Loubet Michel 
Published: November 2019

Considering elements presenting intermediate to high partition coefficients, i.e. less susceptible to have been introduced through contamination by the surrounding magma, it is shown that the composition of a set of peridotitic nodules from alkali-basalts and kimberlite pipes plot in continuity to the one of orogenic lherzolites, defining a same evolution kind.
Through the analysis of the evolution of a set of trace element contents it is shown that this trend should be residual. All these peridotites are interpreted as residual from a lherzolitic upper mantle originally rather homogeneous. The enrichment of most of these nodules in incompatible elements should result from a contamination by a magma rich in these elements (alkali basalt to kimberlitic) during a further process.

Die keltische Grabenobjekte in Südpolen
Authors: Gedl Marek 
Published: November 2019

Celtic funerary objects in Southern Poland.
In Kietrz (Voj. Opole) in Southern High Silesia, were discovered in the necropolis of La Tène culture (with cremation and inhumation Celtic burials) four-angled and circular funerary objects in association with the traces of regularly ranked posts. We find analogues in the Celtic milieu, mainly in Eastern France and in the Rhine region. The custom of depositing funerary objects (little sanctuaries or chapels) on the necropolis first occurs in the eastern part of Middle Europe, at the beginning of La Tène B, with a peopling wave of La Tène culture. Celtic traditions, and especially the custom of depositing four angled funerary objects on necropolis, lasted in Southern Poland (High Silesia and Small Poland) till the phase B2-C1 of the Roman Empire.
The Celts in Western Iberia

The Celtic presence and influence in Western Iberia is largely witnessed not only by its epigraphic traces and the toponymy, but also in its ancient gods and believes.
A general approach to the problem will open this paper ; Then since the Congress is especially centred in artistic aspects, more attention will be given to the general art of the Celts in western Iberia and the decorative motives of ceramics and jewellery.
Die moderne Gesellschaft und die Zukunft / La société moderne et l'avenir

Published: November 2019

Jürgen Moltmann : Modern society and the future.
Modern society is in the process of ruining its own future. The fear of «no future» has genuine causes : it is the result of widespread unemployment, the system of nuclear deterrents, and the ecological crisis. Justice can alone lead to peace and open up a future to the members of the community, to the human community in its successive generations, to the generations of humanity in its natural environment and to the Creation before God.

Le rempart de Damas : un faux pas de Paul ?
Authors: Trocmé Étienne 
Published: November 2019

Etienne Trocmé : The wall of Damascus : A Faux Pas of Paul ?
Why does the apostle Paul unespectedly mention in II Corinthians 11/32-33 his acrobatic escape from Damascus ? There are two reasons for this : (1) that flight had amounted to a somewhat callous desertion of the Damascus Church ; (2) the intruders who questioned Paul's authority in Corinth recalled on that occasion the faux pas Paul had thus made in his early missionary days. This means that they had their roots in Syria-Palestine and were probably part of the «Hellenist» group.
