Microfacies studies of carbonate rocks from Jurassic outcrops in the north of Faro, Southern Portugal

The Middle and Upper Jurassique limestones investigated were sub-divided into nine microfacies (MF) types. The firsts four represent Bathonian sediments with shallow water characteristics typical for carbonate platforms. They are comparable with Wilson's facies zones 6 to 8. Reef and reef debris, near-shore clastic-dominated limestones are not present. These MF-types are reiterated several times without cyclicity. The vertical development of the differentiated facies units indicates a close interfingering. The microfacies data are typical of inter to shallow subtidal environments; both authigenous quartz and low faunal and floral diversity of several layers point to temporary restricted conditions. The occurrence of Dictyoconus cayeuxi LUCAS and Callovian ammonites from the above lying strata argue for a Bathonian age. The MF-types 5-9 (Oxfordian-Kimmeridgian) show completely different sedimentation conditions. Fully marine nearshore recifal limestones alternate with pelagic sediments formed at deeper shelf areas. The pelagic micritic limestones of Oxfordian age are characterized by allodapic intercalations whereas the Oxfordian/Kimmeridgian limestones with tuberolithic fabrics often show intensive silifications. Only initial patch reef growth-stages were reached during the development of the Oxfordian and Kimmeridgian shallow water limestones.

Roy Campbell (1901-1957): o hispanista escocês da África Austral

Cinquenta anos após o trágico desaparecimento de Roy Campbell, em acidente rodoviário ocorrido próximo de Setúbal, vale a pena revisitar a figura deste poeta e hispanista de ascendência escocesa, nascido em Durban, cuja actividade lusófila o torna merecedor de um estudo fatalmente mais vasto do que este artigo visa empreender. Não obstante a importância das vivências sul-africanas e espanholas (por exemplo, o testemunho presencial da eclosão, em 1936, da Guerra Civil), a orientação comparativista desta publicação justifica que privilegiemos as vertentes inglesa e anglo-portuguesa de Roy Campbell, começando por apontar, no que toca à primeira e além do parentesco (familiar, que não político-ideológico...) com George Orwell (1903-1950), a contemporaneidade e os contactos mantidos com poetas, romancistas, ensaístas e críticos como Wyndham Lewis (1884-1957), os irmãos Sitwell (Edith, 1887-1964, Osbert, 1892-1969 e Sacheverell, 1897-1988), T. S. Eliot (1888-1965), 5 Vita Sackville- West (1892-1962), L. P. Hartley (1895-1972), Robert Graves (1895-1985), Edmund Blunden (1896-1974), o também sul-africano Laurens Van der Post (1906-1996) e Dylan Thomas (1914-1953).
