Critical reappraisal of Late Mesozoic-Cenozoic Central and North Atlantic, Caribbean and Mediterranean evolution

(l) The Pacific basin (Pacific area) may be regarded as moving eastwards like a double zip fastener relative to the continents and their respective plates (Pangaea area): opening in the East and closing in the West. This movement is tracked by a continuous mountain belt, the collision ages of which increase westwards. (2) The relative movements between the Pacific area and the Pangaea area in the W-E/E-W direction are generated by tidal forces (principle of hypocycloid gearing), whereby the lower mantle and the Pacific basin or area (Pacific crust = roof of the lower mantle?) rotate somewhat faster eastwards around the Earth's spin axis relative to the upper mantle/crust system with the continents and their respective plates (Pangaea area) (differential rotation). (3) These relative West to East/East to West displacements produce a perpetually existing sequence of distinct styles of opening and closing ocean basins, exemplified by the present East to West arrangement of ocean basins around the globe (Oceanic or Wilson Cycle: Rift/Red Sea style; Atlantic style; Mediterranean/Caribbean style as eastwards propagating tongue of the Pacific basin; Pacific style; Collision/Himalayas style). This sequence of ocean styles, of which the Pacific ocean is a part, moves eastwards with the lower mantle relative to the continents and the upper-mantle/crust of the Pangaea area. (4) Similarly, the collisional mountain belt extending westwards from the equator to the West of the Pacific and representing a chronological sequence of collision zones (sequential collisions) in the wake of the passing of the Pacific basin double zip fastener, may also be described as recording the history of oceans and their continental margins in the form of successive Wilson Cycles. (5) Every 200 to 250 m.y. the Pacific basin double zip fastener, the sequence of ocean styles of the Wilson Cycle and the eastwards growing collisional mountain belt in their wake complete one lap around the Earth. Two East drift lappings of 400 to 500 m.y. produce a two-lap collisional mountain belt spiral around a supercontinent in one hemisphere (North or South Pangaea). The Earth's history is subdivided into alternating North Pangaea growth/South Pangaea breakup eras and South Pangaea growth/North Pangaea breakup eras. Older North and South Pangaeas and their collisional mountain belt spirals may be reconstructed by rotating back the continents and orogenic fragments of a broken spiral (e.g. South Pangaea, Gondwana) to their previous Pangaea growth era orientations. In the resulting collisional mountain belt spiral, pieced together from orogenic segments and fragments, the collision ages have to increase successively towards the West. (6) With its current western margin orientated in a West-East direction North America must have collided during the Late Cretaceous Laramide orogeny with the northern margin of South America (Caribbean Andes) at the equator to the West of the Late Mesozoic Pacific. During post-Laramide times it must have rotated clockwise into its present orientation. The eastern margin of North America has never been attached to the western margin of North Africa but only to the western margin of Europe. (7) Due to migration eastwards of the sequence of ocean styles of the Wilson Cycle, relative to a distinct plate tectonic setting of an ocean, a continent or continental margin, a future or later evolutionary style at the Earth's surface is always depicted in a setting simultaneously developed further to the West and a past or earlier style in a setting simultaneously occurring further to the East. In consequence, ahigh probability exists that up to the Early Tertiary, Greenland (the ArabiaofSouth America?) occupied a plate tectonic setting which is comparable to the current setting of Arabia (the Greenland of Africa?). The Late Cretaceous/Early Tertiary Eureka collision zone (Eureka orogeny) at the northern margin of the Greenland Plate and on some of the Canadian Arctic Islands is comparable with the Middle to Late Tertiary Taurus-Bitlis-Zagros collision zone at the northern margin of the Arabian Plate.

Evolution of Iberia during the Cenozoic with special emphasis on the formation of the Betic Cordillera and its relation with the western Mediterranean

The extensional process affecting Iberia during the Triassic and Jurassic times change from the end of the Cretaceous and, throughout the Palaeocene, the displacement between the African and European plates was clearly convergent and part of the future Internal Zone of the Betic Cordillera was affected. To the west, the Atlantic continued to open as a passive margin and, to the north, no significant deformation occurred. During the Eocene, the entire Iberian plate was subjected to compression. which caused major deformations in the Pyrenees and also in the Alpujarride and Nevado-Filabride, Internal Betic, complexes. In the Oligocene continued this situation, but in addition, the new extensional process ocurring in the western Mediterranean area, together with the constant eastward drift of Iberia due to Atlantic opening, compressed the eastern sector of Iberia, giving rise to the structuring of the Iberian Cordillera. The Neogene was the time when the Betic Cordillera reached its fundamental features with the westward displacement of the Betic-Rif Internal Zone, expelled by the progressive opening of the Algerian Basin, opening prolonged till the Alboran Sea. From the late Miocene onwards, all Iberia was affected by a N-S to NNW-SSE compression, combined in many points by a near perpendicular extension. Specially in eastern and southern Iberia a radial extension superposed these compression and extension.

Tertiary evolution of the São Vicente and Setúbal submarine canyons, Southwest Portugal: insights from seismic stratigraphy

The Setúbal and São Vicente canyons are two major modern submarine canyons located in the southwest Iberian margin of Portugal. Although recognised as Pliocene to Quaternary features, their development during the Tertiary has not been fully understood up to date. A grid of 2D seismic data has been used to characterise the sedimentary deposits of the adjacent flanks to the submarine canyons. The relationship between the geological structure of the margin and the canyon's present location has been investigated. The interpretation of the main seismic units allowed the recognition of three generations of ravinements probably originated after middle Oligocene. Six units grouped in two distinctive seismic sequences have been identified and correlated with offshore stratigraphic data. Seismic Sequence 2 (SS2), the oldest, overlies Mesozoic and upper Eocene deformed units. Seismic Sequence I (SS1) is composed of four different seismic packages separated from SS2 by an erosional surface. The base of the studied sediment ridges is marked by an extensive erosional surface derived from a early/middle Oligocene relative sea-level fall. Deposition in the adjacent area to the actual canyons was reinitiated in late Oligocene in the form of transgressive and channel-fill deposits. A new depositional hiatus is recorded onshore during the Burdigalian, coincident with the unconformity separating SS1 and SS2. This can be correlated with the Arrábida unconformity and with the paroxysmal Burdigalian phase of the Betic domain. Presently, the Setúbal and São Vicente submarine canyons locally cut SS1 and SS2, forming distinctive channels from those recognised on the seismic data. On the upper shelf both dissect highly deformed areas subject to important erosion.

On the hydrogeology of the Lower Tagus Basin and its Cenozoic geologic evolution

The chemical features of the ground water in the Lower Tagus Cenozoic deposits are strongly influenced by lithology, by the velocity and direction of the water movement as well as by the localization of the recharge and discharge zones. The mineralization varies between 80 and 900 mg/l. It is minimal in the recharge zones and in the Pliocene sand and maximum in the Miocene carbonated and along the alluvial valley. Mineralization always reflects the time of permanence, the temperature and the pressure. The natural process of water mineralization is disturbed in agricultural areas because the saline concentration of the infiltration water exceeds that of the infiltrated rainwater. In the discharge zones, the rise of the more mineralized, some times thermal deep waters related to tectonic accidents give rise to anomalies in the distribution of the aquiferous system mineralization model. The diversity of the hydrochemical facies of the ground water may be related to several factors whose identification is some times difficult.

Palynologic data from Aquitaine (SW France) Middle Miocene Sables Fauves Formation. Climatic evolution

Climatic reconstructions based on palynological data from Aquitaine outcrops emphasize an important degradation phase during the Lower Serravallian. Climatic and environmental changes can be related to sea-level variations (Bur 5 / Lan 1, Lan 2 / Ser 1 and Ser 2 cycles). Transgressive phases feature warmer conditions and more open environments whereas regressive phases are marked by a cooler climate and an extent of the forest cover. From Langhian to Middle Serravallian, a general cooling is highlighted, with disappearance of most megathermic taxa and a transition from warm and dry climate to warm-temperate and much more humid conditions. Conclusions are consistent with studies on bordering areas and place the major degradation phase around 14 My. The palynologic data allow filling a gap in the climatic evolution of Southern France, as a connection between Lower and Upper Miocene, both well recorded. These results document, on Western Europe scale, latitudinal climatic gradient across Northern hemisphere while featuring a transition between Mediterranean area and northeastern Atlantic frontage.

Os reais hospitais militares em Portugal administrados e fundados pelos Irmãos Hospitaleiros de S. João de Deus 1640-1834

RESUMO: Desde 1640 até data extrema de 1834, os Irmãos Hospitaleiros de S. João de Deus foram os responsáveis, directa e indirectamente, pela administração e corpo de enfermagem dos Reais Hospitais Militares em Portugal, actividades que analisamos ao longo dos séculos, desenvolvendo pressupostos temáticos relativamente a sua actuação no tempo e no espaço. É durante o séc. XVII até ao séc. XIX, que vemos os cuidados da corte para com a assistência aos soldados enfermos e doentes, ao publicar inúmera legislação relativamente à complexidade assistencial na área militar, a qual foi por nós compilada para melhor contextualização da importância dos Hospitais Militares em Portugal. Os Regimentos, os Alvarás, os Regulamentos e as Ordens do Dia, constituem um objecto fundamental de pesquisa e análise para caracterizar o quotidiano nesses mesmos locais. Os Hospitais Militares desde a sua fundação, dos primórdios das Guerras da Aclamação em 1640, até ao advento do liberalismo em 1834, eram centros de conhecimento técnico e científico com um corpo assistencial especializado, onde um conjunto pluridisciplinar de profissionais zelava qualitativamente pelos assistidos, e onde os Irmãos Hospitaleiros de S. João de Deus desempenhavam funções de administradores, enfermeiros e capelães. Nesse sentido elaboramos uma listagem cronológica para inter relacionar os Irmãos Hospitaleiros e os Hospitais Militares, pois é impossível separar a Ordem de S. João de Deus da componente assistencial aos enfermos e doentes militares em Portugal. A importância urbana e arquitectónica, que os Reais Hospitais Militares tiveram no contexto orgânico e defensivo nas Praças de Guerra, é realçado pela forma como estes se encontravam implantados e construídos, demarcando-se esteticamente da globalidade edificada, pois constituíam parte integrante dos equipamentos militares, como era teorizado pelos técnicos militares. Assim analisamos a localização dos imóveis, para além do próprio edifício hospitalar, com o meio, ou seja com a urbanidade das Praças de guerra. A sobriedade arquitectónica dos Hospitais Militares, integrada nos grandes ciclos das correntes culturais europeia e nacional, associada à riqueza decorativa e iconoclasta desenvolvida nesses locais, dá-nos uma dimensão da importância científica que esses núcleos assistenciais tiveram, contribuindo para a difusão do culto e circulação da imaginária de S. João de Deus em Portugal e dos Santos venerados nos Hospitais Militares. Desta forma compreendemos o alicerçar devocional que o reino tinha por este Santo, como o fundador do conceito assistencial do hospital moderno. Estando intrinsecamente ligado a este facto vemos o proliferar do culto e da imaginária de S. João de Deus em Portugal, centrando-se a iconografia artística do Santo em torno das localidades onde se enraizaram os Hospitais Militares. Hoje, nos imóveis hospitalares, não é difícil analisar uma lenta evolução da funcionalidade dos seus espaços, gravitando o desenvolvimento estrutural assistencial em torno das enfermarias e salas de cirurgia, mantendo-se perene este arquétipo arquitectónico desde o séc. XVII até meados do séc. XIX, as quais foram levantadas, comparadas e analisadas. Foi com a exclaustração das Ordens Religiosas, pelo Decreto de 29 de Maio de 1834, que acabou a extraordinária e valorosa acção administrativa, tutelar e corpo de enfermagem dos Irmãos Hospitaleiros de S. João de Deus, na área específica da assistência militar em Portugal, extinguindo-se, nalguns casos, os Hospitais Militares, pois o reino não estava preparado para substituir esses profissionais de saúde. O nosso estudo desenvolve-se por cerca de 295 anos, espaço temporal em que os Hospitais Militares foram administrados e fundados pelos Irmãos de S. João de Deus em Portugal.---------ABSTRACT: Since 1640 until 1834 the Hospitaller Brothers of S. John of God were the responsibles, direct and indirectly, for the administration and nursing body of the Royal Military Hospitals in Portugal, activities that we analyse throughout the centuries, developing thematic presuppositions regarding its performance in time and in space. It is during the 17th century until the 19th century, that we see the court’s care with the assistance of the wounded and sick by the publishing of much legislation regarding the assistance complexity in the military area, which was compiled by us in order to achieve a better comprehension of the importance of the Military Hospitals in Portugal. The Regiments, Charters, Regulations and Orders of Day constitute a fundamental object of research and analysis to characterise the quotidian of these locations. The Military Hospitals, since its foundation, in the beginning of the Wars of Acclamation in 1640, until the advent of liberalism in 1834, were centres of technical and scientific knowledge with a specialized assistance body, were a multidisciplinary set of professionals took qualitatively care of the attended, and where the Hospitaller Brothers of S. John of God performed the tasks of administrators, nurses and chaplains. In this perspective, we created a chronological listing in order to relate the Hospitaller Brothers with the Military Hospitals, since it is impossible to separate the Hospitaller Order of S. John of God from the component of assistance to the military sick and wounded in Portugal. The urban and architectural importance that the Royal Military Hospitals had in the organic and defensive context of the War Fortifications is emphasized by the way these were implanted and built and by its architectural demarcation of the edified whole, since they constituted an integrant part of the military equipments, as it was theorized for the military architecture. Therefore we analyse the location of the real estate, analysing not only the hospital building itself, but also its relation with the environment, i. e. with the urbanism of the war fortifications. The architectural sobriety of Military Hospitals, integrated in the big cycles of cultural streams in Europe and Portugal, associated to the decorative and iconoclastic wealth developed in these locations, give us a dimension of the scientific importance that these hospitals had, contributing to the diffusion of the cult and circulation of sculptures and paintings of S. John of God in Portugal and of the Saints revered in the Hospitals. In this way, we understand the consolidation of the devotion that the kingdom had for this Saint, the founder of the assistance concept of the modern hospital. The proliferation of the cult and iconography of S. John of God is intrinsically connected to this fact, the artistic iconography concentrating itself around the localities were the Military Hospitals were built. Today, in the assistance buildings, it is not difficult to analyse a slow evolution of the functionality of its spaces, gravitating the structural assistance development around the infirmaries and surgery rooms, this architectural archetype being perennial from the 17th century until the middle of the 19th century. These infirmaries were pointed out, compared and analysed. It was the expulsion of the Religious Orders, by the Decree of May 29th 1834, that ended with the extraordinary and valorous administrative and tutelary action and nursing body of the Hospitaller Brothers of S. John of God, in the specific area of military assistance in Portugal, extinguishing, in some cases, the Military Hospitals, since the kingdom wasn’t prepared to substitute these health professionals. Our study is developed in a timeframe of 295 years, period in which the Military Hospitals were administrated and founded by the Brothers of S. John of God in Portugal.
