Improving visual attractiveness to enhance city-river integration - a methodolo...
Silva, J.B.; Saraiva, M.G.; Ramos, I.L.; Bernardo, F.The relationship between rivers and cities has evolved from a natural coexistence and interdependence to a progressive relationship of segregation and disintegration. This article uses a planning experiment to explore and discuss some concerns about visual attractiveness of city–river landscapes in promoting spatial integration of cities and rivers. It presents a methodological approach integrating expert opini...
The missing Rheic Ocean magmatic arcs: Provenance analysis of Late Paleozoic
Pereira, M.F.; Chichorro, M.; Johnston, S.T.; Gutierrez-Alonso, G.; Silva, J.B.; Linnemann, U.; Hofmann, M.; Drost, K.Early Carboniferous turbiditic sedimentary rocks in synorogenic basins located on both sides of the Rheic suture in SW Iberiawere studied for provenance analysis. An enigmatic feature of this suture, which resulted from closure of the Rheic Ocean with the amalgamation of Pangea in the Late Carboniferous, is that there are no recognizable mid- to Late Devonian subduction-related magmatic rocks,which should have ...
The provenance of Late Ediacaran and Early Ordovician siliciclastic rocks in th...
Pereira, M.F.; Linnemann, U.; Hofmann, M.; Chichorro, M.; Solá, A.R; Medina, J.; Silva, J.B.U–Pb geochronology of detrital zircon from Late Ediacaran (Beiras Group greywackes) and Early Ordovician (Sarnelhas arkosic quartzites and Armorican quartzites of Penacova) sedimentary rocks of the southwest Central Iberian Zone (SW CIZ) constrain the evolution of northern Gondwana activepassive margin transition. The LAICPMS U–Pb data set (375 detrital zircons with 90–110% concordant ages) is dominated by Neop...
North-Gondwana assembly, break-up and paleogeography: U–Pb isotope evidence fro...
Pereira, M.F.; Solá, A.R.; Chichorro, M.; Lopes, L.; Gerdes, A.; Silva, J.B.The Estremoz Anticline in the Ossa-Morena Zone (SW Iberia) includes upper Ediacaran detrital rocks uncon- formably overlain by lower Cambrian detrital and carbonate rocks. The spectra of detrital zircon U–Pb ages dominated by Cryogenian and Ediacaran ages (with a typical gap in Mesoproterozoic ages) of the upper Edi- acaran greywackes and lower Cambrian arkosic sandstones indicate provenance from sources placed...
Detrital zircon from a late Paleozoic accretionary complex of SW Iberia (Varisc...
Pereira, M.F.; Drost, K.; Chichorro, M.; Silva, J.B.; Sola, R.In this study we present new U-Pb ages of detrital zircons from greywackes and quartzites of the Pulo do Lobo Anticline (PLA) that have been interpreted to represent a Late Paleozoic accretionary complex in SW Iberia. The PLA separates the Ossa Morena Zone, which has a North- Gondwana affinity throughout Late Ediacaran and Early Paleozoic times, from the South Portuguese Zone, which is considered to be underlai...
