Evolução tectónica mesozóica da Bacia Lusitaniana

The evolution of the Lusitanian Basin, localized on the western Iberian margin, is closely associated with the first opening phases of the North Atlantic. It persisted from the Late Triassic to the Early Cretaceous, more precisely until the end of the Early Aptian, and its evolution was conditioned by inherited structures from the variscan basement. The part played by the faults that establish its boundaries, as regards the geometric and kinematic evolution and the organization of the sedimentary bodies, is discussed here, as well as with respect to important faults transversal to the Basin. A basin evolution model is proposed consisting of four rifting episodes which show: i) periods of symmetrical (horst and graben organization) and asymmetrical (half graben organization) geometric evolution; ii) diachronous fracturing; iii) rotation of the main extensional direction; iv) rooting in the variscan basement of the main faults of the basin (predominantly thick skinned style). The analysis and regional comparison, particularly with the Algarve Basin, of the time intervals represented by important basin scale hiatuses near to the renovation of the rifting episodes, have led to assume the occurrence of early tectonic inversions (Callovian–Oxfordian and Tithonian–Berriasian). The latter, however, had a subsequent evolution distinct from the first: there is no subsidence renovation, which is discussed here, and it is related to a magmatic event. Although the Lusitanian Basin is located on a rift margin which is considered non-volcanic, the three magmatic cycles as defined by many authors, particularly the second (approx. 130 to 110 My ?), performed a fundamental part in the mobilization of the Hettangian evaporites, resulting in the main diapiric events of the Lusitanian Basin. The manner and time in which the basin definitely ends its evolution (Early Aptian) is discussed here. Comparisons are established with other west Iberian margin basins and with Newfoundland basins. A model of oceanization of this area of the North Atlantic is also presented, consisting of two events separated by approximately 10 My, and of distinct areas separated by the Nazaré fault. The elaboration of this synthesis was based on: - information contained in previously published papers (1990 – 2000); - field-work carried out over the last years, the results of which have not yet been published; - information gathered from the reinterpretation of geological mapping and geophysical (seismic and well logs) elements, and from generic literature concerning the Mesozoic of the west iberian margin.

Zonal distribution of gold and platinium group elements in the Mondunguara deposits Mozambique

The Mondunguara copper mines are situated in mountainous terrain in west-central Mozambique. The mineralization consists of chalcopyrite, pyrrhotite, common pcntlandite, cobaltpentlandite, pyrite and several minor oxides and sulphides in tabular ore bodies deeping steep to the north. Gold was known to occur in small quantities but no systematic sampling and analysis for precious clements was ever done. Mineralogical and geological evidence has shown that the ores are magmatic in origin and were derived from gabbro-peridotitic magma dykes saturated in sulphides when intruded. The ore bodies show a clear zonation. Platinum group elements as well as pure gold are associated with high temperature hexagonal pyrrhotite. This pyrrhotite being of no use is generally discarded to the tailing dumps. Late hydrothermal phases are enriched in native silver, silver tellurides as well as electrum.

Fundamentos teóricos e objectivos estratégicos de uma unidade de ética em saúde pública : caso de estudo : o gabinete de ética e responsabilidade da Direcção-Geral da Saúde

RESUMO - Este trabalho de projecto visa responder à questão de saber como gerir uma unidade de ética num serviço público central de saúde pública, “de forma racional e informada”, definindo os seus objectivos estratégicos (Baranger, citando Drucker, 1990) utilizando como caso de estudo o Gabinete de Assuntos Jurídicos, Ética e Responsabilidade, adiante designado por Gabinete, da Direcção‐Geral da Saúde. Para o efeito, fez‐se, em primeiro lugar, uma abordagem teórica descritiva das bases filosóficas da ética realçando a sua aplicação prática na determinação das características dos sistemas de saúde. Em seguida, analisa‐se a utilização do conceito de ética no âmbito da Saúde Pública, no contexto da bioética, verificando‐se elementos distintivos que parecem justificar a autonomização do conceito de ‘Ética em Saúde Pública’. Para tal, foram consultadas as principais fontes de princípios éticos em saúde, tais como a Declaração Universal dos Direitos do Homem, a Declaração de Helsínquia, bem como a Constituição da República Portuguesa e os Códigos Deontológicos das profissões de saúde. Nesta fase do trabalho é pesquisada, nas perspectivas nacional e internacional, a existência de unidades de ética, congéneres ou de âmbito similar, bem como respectivas áreas e níveis de intervenção, tendo‐se nesse sentido auscultado as entidades idóneas dos Estados‐Membros da União Europeia. Na segunda parte do trabalho de projecto, desenvolveu‐se o planeamento estratégico através da aplicação da metodologia balanced scorecard, apresentando‐se uma proposta de objectivos estratégicos e iniciativas a serem desenvolvidas pelo gabinete de ética sub judice, para um horizonte temporal fixado em três anos. Da utilização desta metodologia resultaram doze objectivos estratégicos, dos quais se destacam: ‘fomentar a discussão ética’; ‘promover a igualdade dos utentes do SNS’; e ‘identificar prioridades de actuação’. Entre as iniciativas a desenvolver salienta‐se o desenho de um questionário, a aplicar às comissões de ética do sistema de saúde com o objectivo de identificar prioridades de actuação do Gabinete. O trabalho finaliza‐se com as conclusões, recomendações e linhas de investigação que se considera deverem ser desenvolvidas, num futuro próximo, para o aprofundamento da matéria alvo deste estudo. ------------------ABSTRACT - This research‐project aims to answer the question of how to manage a unit of ethics within the directorate‐general of public health in a "rational and informed” way, defining their strategic goals (Baranger, quoting Drucker, 1990) using as case study the Office of Legal Affairs, Ethics and Responsibility, hereinafter referred as the Office, of the Directorate‐General of Health. For this purpose, the first part of the study, includes a framework description of the main philosophical basis of ethics, emphasizing that its practical application determines the characteristics of health systems; the use of the concept of ethics of Public Health in the context of bioethics was analyzed, and distinctive elements were found that seem to justify the autonomy of the concept of 'Ethics of Public Health'. The main sources of this part were the fundamental ethical principles in health, such as the Universal Declaration of Human Rights, the Helsinki Declaration, and also the Constitution of the Portuguese Republic and the Codes of Ethics of the health professions. At this stage of the study a description is also made, at both a national and international perspective, on the existence of similar units of ethics or with similar scope, and their areas and levels of intervention. For the international dimension the appropriate bodies of the Member States the European Union were consulted. In the second part of the research‐project, a strategic planning for the Office was designed, using the balanced scorecard methodology, and a proposal of the strategic objectives and initiatives to be developed within a time schedule of three years are presented. The use of this method resulted in twelve strategic objectives, among which we note the following: 'to promote the ethical discussion'; 'to promote equality of users of the NHS'; and ‘to identify priorities for action’. The design of a questionnaire to be answered by the ethics committees for health of the Portuguese health system, in order to identify priorities for the Office’s activities is also presented in the study. The work ends with the conclusions and recommendations, as well as a suggestion of lines for future research to further investigate the subject of this study.
