Precambrian geodynamics and ore formation: The Fennoscandian Shield

Compared with present-day global plate tectonics, Archaean and Palaeoproterozoic plate tectonics may have involved faster moving, hotter plates that accumulated less sediment and contained a thinner section of lithospheric mantle. This scenario also fits with the complex geodynamic evolution of the Fennoscandian Shield from 2.06 to 1.78 Ga when rapid accretion of island arcs and several microcontinent-continent collisions in a complex array of orogens was manifested in short-lived but intense orogenies involving voluminous magmatism. With a few exceptions, all major ore deposits formed in specific tectonic settings between 2.06 and 1.78 Ga and thus a strong geodynamic control oil ore deposit formation is suggested. All orogenic gold deposits formed syn- to post-peak metamorphism and their timing reflects the orogenic younging of the shield towards the SW and west. Most orogenic gold deposits formed during periods of crustal shortening with peaks at 2.72 to 2.67, 1.90 to 1.86 and 1.85 to 1.79 Ga. The ca. 2.5 to 2.4 Ga Ni-Cu PGE deposits formed both as part of layered igneous complexes and associated with mafic volcanism, in basins formed during rifling of the Archaean craton at ca. 2.5 to 2.4 Ga. Svecokarelian ca. 1.89 to 1.88 Ga Ni-Cu deposits are related to mafic-ultramafic rocks intruded along linear belts at the accretionary margins of microcratons. All major VMS deposits in the Fennoscandian Shield formed between 1.97 and 1.88 Ga, in extensional settings, prior to basin inversion and accretion. The oldest "Cyprus-type" deposits were obducted onto the Archaean continent during the onset of convergence. The Pyhasalmi VMS deposits formed at 1.93 to 1.91 Ga in primitive, bimodal arc complexes during extension of the arc. In contrast, the Skellefte VMS deposits are 20 to 30 million years younger and formed in a strongly extensional intra-arc region that developed on continental or mature arc crust. Deposits in the Bergslagen-Uusimaa belt are similar in age to the Skellefte deposits and formed in a microcraton that collided with the Karelian craton at ca. 1.88 to 1.87 Ga. The Bergslagen-Uusimaa belt is interpreted as an intra-continental, or continental margin back-arc, extensional region developed on older continental crust. Iron oxide-copper-gold (IOCG) deposits are diverse in style. At least the oldest mineralizing stages, at ca. 1.88 Ga, are coeval with calc-alkaline to monzonitic magmatism and coeval and possibly cogenetic subaerial volcanism more akin to continental arcs or to magmatic arcs inboard of the active subduction zone. Younger mineralization of similar style took place when S-type magmatism occurred at ca. 1.80 to 1.77 Ga during cratonization distal to the active N-S-trending subduction zone in the west. Possibly, interaction of magmatic fluids with evaporitic sequences in older rift sequences was important for ore formation. Finally, the large volumes of anorthositic magmas that characterize the Sveconorwegian Orogeny formed a major concentration of Ti in the SW part of the Sveconorwegian orogenic belt under granulite facies conditions, about 40 million years after the last regional deformation of the Sveconorwegian Orogeny, between ca. 930 and 920 Ma.

Prêcher la Trinité dans le royaume carolingien. Un facteur de cohésion de l’Imperium christianum ?

Une lecture attentive des admonestations ecclésiastiques de Charlemagne laisse entrevoir un renforcement très net du souci du souverain de l'enseignement de la doctrine chrétienne au lendemain du couronnement impérial. La foi en la Trinité s'impose dans les capitulaires des missi des quinze premières années du IXe siècle comme l'une des priorités du programme religieux. Or, cet intérêt impérial ne date pas du couronnement. Il était déjà exprimé dans le texte fondateur de la réforme carolingienne, l'Admonitio Generalis de 789. Dans cette communication, l'auteur proposait un passage en revue des grandes étapes de l'instauration de l'enseignement de la doctrine trinitaire, d’abord en Francia, puis dans l'empire suivi d'un examen de quelques textes représentatifs du processus de maturation de la "théologie impériale". Il s'arrêtait ensuite sur les moyens mis à la disposition du clergé pour se préparer à enseigner ce mystère avant de formuler l'hypothèse d'une notable influence de cette "prédication" de la Trinité sur le processus d'unification de l'empire renaissant.
