On the Use of Thermal Properties for Characterizing Dimension Stones
Amaral, Paulo; Correia, António; Lopes, Luís; Rebola, Paula; Pinho, António; Lopes, José CarrilhoThe use of dimension stones in architecture and civil engineering implies the knowledge of several mechanical, physical, and chemical properties. Even though it has been usual practice to measure physical and mechanical properties of dimension stones the same is not true for thermal properties such as thermal conductivity, thermal diffusivity, specific heat capacity, and heat production. These properties are pa...
AMS and IRM studies in the late-variscan Santa Eulália Plutonic Complex (Ossa-M...
Sant’Ovaia, Helena; Gomes, Celeste; Lopes, José Carrilho; Nogueira, Pedro; Cruz, Cláudia; Rocha, ArmandoThe 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...
Lopes, José Carrilho; Sant'Ovaia, Helena; Nogueira, Pedro; Martins, Helena; Noronha, Fernando; Lopes, LuisThe 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...

Lopes, Luis; Lopes, José Carrilho; Sant'Ovaia, Helena; Nogueira, Pedro; Ribeiro, Maria dos AnjosThe 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)
Cruz, Cláudia; Ribeiro, Maria; Martins, Helena; Sant'Ovaia, Helena; Nogueira, Pedro; Lopes, José Carrilho; Lopes, LuísO 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...
Composições Mineralógicas Virtuais em Rochas Ígneas: Norma CIPW
Lopes, José CarrilhoAs rochas ígneas são estudadas, em primeira aproximação, a partir dos seus aspetos petrográficos que incluem a determinação qualitativa e quantitativa da composição mineralógica, bem como a análise de critérios texturais que, entre outros objetivos, visa estabelecer a ordem de cristalização dos diferentes minerais presentes. Em rochas de origem vulcânica, o súbito arrefecimento do magma pode, em casos extremos,...
Correlation of magnetic susceptibility with 18O data in magnetite- and ilmenit...
Sant'Ovaia, Helena; Martins, Helena; Lopes, José Carrilho; Machado, Joana; Noronha, FernandoThe 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
Sant'Ovaia, Helena; Nogueira, Pedro; Lopes, José Carrilho; Dória, Armanda; Gomes, Celeste; Cruz, Cláudia; Noronha, FernandoO 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...

Sant'Ovaia, Helena; Lopes, José Carrilho; Nogueira, Pedro; Gomes, Celeste; Cruz, Cláudia; Machado, JoanaThe 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...
