AMS and IRM studies in the late-variscan Santa Eulália Plutonic Complex (Ossa-M...

The Santa Eulália Plutonic Complex (SEPC) is a calc-alkaline granitic body, with an area of 400 km2, and is located in the north of the Ossa Morena Zone of the Variscan Iberian sector, near the limit with the Central Iberian Zone. SEPC is considered late-Variscan because it cross-cuts the regional variscan structures. The host rocks are metamorphic formations from Upper Proterozoic to Lower Paleozoic. The SEPC ...

Petrogenesis of the Santa Eulália Plutonic Complex (Alentejo, Portugal): contri...

The Santa Eulalia Plutonic Complex (SEPC) is a late-Variscan granitic massif with elliptical contours intersecting the NW-SE Variscan dominant regional structures in the most northerly sectors of the Ossa-Morena Zone (Iberian massif). The host rocks of this plutonic complex are meta-sedimentary formations generated between Proterozoic and Lower Paleozoic, some of them strongly affected by contact metamorphic pr...

Santa Eulália Plutonic Complex (Southern Portugal): petrology, geochemistry and...

The Santa Eulália Plutonic Complex (SEPC) is a 400 km2 late variscan granitic pluton in the SW sector of the Iberian Variscides which cross-cuts the regional NW-SE Upper Proterozoic to Lower Palaeozoic lithological units. From the rim to the core, SEPC shows a medium- to coarse-grained pink granite (G0 group) involving large elongated masses of mafic to intermediate rocks (M group) and a central grey monzonitic...

Efeitos térmicos induzidos pelo Complexo Plutónico de Santa Eulália (ZOM)

O Complexo Plutónico de Santa Eulália (CPSE) é um corpo granítico tardi-varisco situado próximo do limite entre a Zona Centro Ibérica (ZCI) e a Zona Ossa Morena (ZOM) mais concretamente na parte norte da Zona Ossa Morena do maciço Ibérico Varisco. Este plutão tem cerca de 400 km2 e corta estruturas variscas de orientação predominante NW-SE. As rochas do encaixante do CPSE englobam unidades meta-ígneas e metas...

Late-Variscan emplacement and genesis of the Vieira do Minho composite pluton, ...

In the Central Iberian Zone synorogenic (syn- and late-D-3, the last deformation phase) composite batholiths of biotite-rich granitods with peraluminous character are well represented. We report here U-Pb zircon and monazite ages, geochemical, Sr-Nd-O isotopic data and Anisotropy of Magnetic Susceptibility (AMS) studies for the late-D-3 Vieira do Minho pluton, in northern Portugal. AMS reveals the paramagnetic ...

Correlation of magnetic susceptibility with 18O data in magnetite- and ilmenit...

The relationship between oxygen isotopic values and magnetic susceptibility composition on 11 Variscan Portuguese granites has been investigated. Whole-rock oxygen-isotope (18O ) values for Vieira do Minho (VM), Vila Pouca de Aguiar (VPA), Chaves, Castelo Branco (CB), Manteigas and Serra da Estrela (SE) granitoids, were compilated from bibliography [1,2,3,4], and 18O for Santa Eulalia Plutonic Complex (SEPC)...

Petrofísica e Geoquímica no Complexo Plutónico de Santa Eulália

O Complexo Plutónico de Santa Eulália (CPSE) é um corpo granítico calco-alcalino situado na parte norte da Zona da Ossa Morena do maciço Ibérico Varisco. O complexo é considerado tardi-Varisco, uma vez que corta estruturas regionais variscas. O CPSE é um complexo anelar onde podem identificar-se, da periferia para o centro: (i) uma fácies granítica de cor rosa e grão médio a grosseiro (G0) que envolve corpos de...

Petrophysical and geochemical characterization of the late-variscan Santa Eulál...

The Santa Eulália Plutonic Complex (SEPC) is a calc-alkaline granitic body located in the northern part of the Ossa Morena Zone, composed by a medium- to coarse-grained pink granite (G0 group) involving large elongated masses of mafic (gabbroic) to intermediate (granodioritic) rocks, M group, and a central gray monzonitic granite (G1 group) which present dominant medium granular facies. A multidisciplinary stud...
