Contribución al conocimiento de la geología del depósito de Au-Cu de La Pava (Península de Azuero, Panamá)

The «La Pava» Au-Cu deposit is hosted by a vulcanosedimentary sequence, named Ocú Formation,developed in an island arc environment that resulted from the subduction of the Nazca Plate beneath the Caribbean Plate during the Cretaceous times. The deposit consists of disseminations and stockworks of pyrite and chalcopyrite accompanied by barite, quartz and carbonates. Three hydrothermal alteration zones have been recognized: silicic, argillic and propilityc, typical of gold-related high sulfidation systems. A supergenic alteration overprints the hydrothermal alterations developing a cap rich in silica and Feoxides. The detailed study of the Ocú Fm. indicates that the sulfides and the accompanying gold was formed in a submarine environment. Therefore we suggest that «La Pava» represents an Au-Cu hybrid deposit between high sulphidation epithermal and VMS types, which are found in volcanogenic massive sulphide environments.

La Religió ibèrica en el territori de la Indigècia

Aquest treball parteix de la pregunta: quines eren les característiques principals de la religió ibèrica? A partir d’aquesta pregunta, n’han sorgit d’altres que han permès concretar aspectes més específics de la religió en aquest territori: quins llocs de culte utilitzaven?, quines divinitats veneraven?, qui s’encarregava de dur a terme el culte?, com es manifestava aquesta religió?, creien en el més enllà?, quins ritus o pràctiques cultuals realitzaven?

[cat] Es donen a conèixer diversos objectes singulars localitzats en superfície en els jaciments ibèric i romà de la Fogonussa, que romanien inèdits en la població de Sant Martí de Maldà, municipi de Sant Martí de Riucorb. La selecció està formada per una vora d'àmfora grecoitàlica tardana, que conté una inscripció ibèrica, dues nanses de vasos contenidors ibèrics amb grafits i tres nanses d'àmfora ibèrica estampillades, una d'elles amb la figura d'un griu.

Homogenization Dynamics and Introduction Routes of Invasive Freshwater Fish in the Iberian Peninsula

Nonnative invasive species are one of the main global threats to biodiversity. The understanding of the traits characterizing successful invaders and invasion-prone ecosystems is increasing, but our predictive ability is still limited. Quantitative information on biotic homogenization and particularly its temporal dynamics is even scarcer. We used freshwater fish distribution data in the Iberian Peninsula in four periods (before human intervention, 1991, 1995, and 2001) to assess the temporal dynamics of biotic homogenization among river basins. The percentage of introduced species among fish faunas has increased in recent times (from 41.8% in 1991 to 52.5% in 2001), leading to a clear increase in the similarity of community composition among basins. The mean Jaccard's index increase (a measure of biotic homogenization) from the pristine situation to the present (17.1%) was similar to that for Californian fish but higher than for other studies. However, biotic homogenization was found to be a temporally dynamic process, with finer temporal grain analyses detecting transient stages of biotic differentiation. Introduced species assemblages were spatially structured along a latitudinal gradient in the Iberian Peninsula, with species related to sport fishing being characteristic of northern basins. Although the comparison of fish distributions in the Iberian Peninsula and France showed significant and generalized biotic homogenization, nonnative assemblages of northeastern Iberian basins were more similar to those of France than to those of the rest of the Iberian Peninsula, indicating a main introduction route. Species introduced to the Iberian Peninsula tended to be mainly piscivores or widely introduced species that previously had been introduced to France. Our results indicate that the simultaneous analysis of the spatial distribution of introduced assemblages (excluding native species that reflect other biogeographical patterns) and their specific traits can be an effective tool to detect introduction and invasion routes and to predict future invaders from donor regions

Presence of the Nearctic Water Boatman Trichocorixa Verticalis Verticalis (Fieber, 1851) (Heteroptera, Corixidae) in the algarve region (S Portugal)

This paper describes the presence of the nearctic water boatman Trichocorixa verticalis verticalis in southern Portugal. This species has been cited recently for the first time in Europe from individuals captured in southern Spain. This species, native to Atlantic coast of America, has also been cited from New Caledonia and South Africa, and has been found in the open sea. Two kinds of introduction are reported for this species: involuntary introduction with exotic fish, and passive dispersion through marine currents and severe storms. The possibility of this kind of introduction in Europe is discussed

Argilas bentoníticas da península de Santa Elena, Equador: pilarização, ativação ácida e seu uso como descolorante de óleo de soja

Two samples of calcic bentonite of the Santa Elena Peninsula, Ecuador, were pillared with Al13 ions in the ratio of 10, 15 and 20 meq of Al g-1 of clay, calcinated at 573, 723 and 873 ºK and acid activated with 4, 6 and 8 mol L-1 H2SO4. Analyses by X-ray diffraction, X-ray fluorescence, differential and gravimetric thermal, density, surface area and porosity, were applied in order to study the modifications occurred in the crystalline structure of the montmorillonite. The 8 mol L-1 H2SO4 acid-activated 15 meq of Al g-1 of clay at 573 ºK Al-pillared samples indicated the best results in the bleaching of the soybean oil measured by UV-visible spectrophotometer.
