Paralophiodon cf. leptorhynchum (tapiroidea, mammalia) à Vale Furado: contribution à la connaissance de l’éocène au Portugal

A canine tooth from Vale Furado is classified as Paralophiodon cf. leptorhynchum. The genus Paralophiodon indicates an age from Lower Lutetian to Auversian, Middle Eocene. As it belongs in the lineage of P. leptorhynchum, possible age span is furth~L~uced from Middle Lutetian to Auversian. This conclusion remains valid or nearly so even in the less probable case of confusion with some form included in P. isselensis lineage. Our previous (1975) datation for sandstones and pelites from Vale Furado is thus confirmed, and more accurately recognized. Paralophiodon and the crocodilian Iberosuchus are a rather sound basis for correlation with stratigraphical units near Zamora and Salamanca in Spain.

Ocorrência de ouro nos depósitos pliocénicos da região de Cruz de Pau (Seixal)

Recently had been discovery, in the area of the construction of the Carla Sacramento Athletics Stadium at Cruz de Pau (Seixal), a set of stopes and wells with characteristics of ancient Roman mining activities. The old mining works are incised in pliocene sandy formations with conglomeratic facies, where four preliminary samples were collected in a coarser level with subrounded pebbles. The heavy minerais of those samples were studied in accordance with the Heavy Mineral Concentrate Laboratory of the IGM. The previously mentioned facies has interesting gold percentages and the presence of grey (nodular) and classic monazite, xenotime, cassiterite, spinels s.l., ilmenite and rutile. The morphology of the gold grains as well as the heavy minerals shows two phases of transport; an initial fluvial phase and a secondary aeolian phase influenced their concentracion. The high percentage of toroid grains showing evidence of wind ablation, suggests that this was the main factor for reconcentration of the gold. The amount of gold particles obtained in the concentrates is considerable and in one sample, a grade of 3.2 ppm was calculated. The samples also have been analysed for Au + 34 elements by INAA and ICP-MS, the results of which show similar grades as previously obtained.
