Dados geocronológicos para o soco pré-Mesozoico localizado a Oeste da Falha Por...

SUMMARY: Geochronological data from the pre-Mesozoic basement of the Lusitanian Basement (West of the Porto-Tomar Fault) was obtained. Results show a predominant Cadomian/Pan-African and Eburnean inheritance/source, placing this sector as a peri-Gondwanan domain. However, two major differences can be seen in the data: samples with a clear absence in Mesoproterozoic ages vs. samples with a clear presence of thes...

Programa de cartografia transfronteiriça do LNEG-IGME na Zona Sul Portuguesa na...

SUMMARY: The South Portuguese Zone (SPZ) 1/200 000 and 1/400 000 scale maps and stratigraphic program in SW Iberia is presented by a LNEG-IGME consortium and funded by GEO_FPI/Interreg-POCTEP. The 1/200 000 mapped area corresponds to the border area and is based on previous work (Folha 8 and Sevilla-Puebla de Guzmán maps). The 1/400 000 map covered a larger area, from Lisbon to Seville. The following domains of...

A new approach to palynostratigraphy of the middle late Famennian Gafo Formatio...

ABSTRACT: New palynological results from the Gafo Formation (southern sector of the Pulo do Lobo Domain, South Portuguese Zone) are integrated with recently studied sections and drillholes from the Portuguese and Spanish sectors. A total of 44 samples were studied, 27 of which were positive for palynomorph taxonomy. This research revealed well preserved palynological assemblages, including 73 spore species allo...

A total of 44 samples were studied, 27 of which were positive for palynomorph taxonomy. This research revealed well preserved palynological assemblages, including 73 spore species allocated to 2...
