Roseiro, José; Moreira, Noel; Andrade, Laura; Nogueira, Pedro; de Oliveira, Daniel Pipa Soares; Eguiluz, Luis; Mirao, Jose; Moita, PatríciaABSTRACT: he Cambrian Series 2 Carbonate Formation from the Alter do Chão Elvas-Cumbres Mayores unit (Ossa-Morena Zone, SW Iberian Massif) is composed of regionally metamorphosed marbles and marlstones that underwent chlorite zone metamorphism and preserve the primaeval limestone 87Sr/86Sr ratios (0.7083–0.7088). These are consistent with the established Lower Cambrian seawater curve, and therefore used for age...

Rosa, Jéssica; Moreira, Noel; Santos, José Francisco; Ribeiro, SaraThe exploitation of carbonate crystalline rocks in the Ossa-Morena Zone (OMZ) dates back more than two thousand years. Several historical exploitation poles in OMZ were identified based on the identification of distinctive marble lithotypes in Roman consumption areas, and some of those historical exploitation places were, subsequently, identified in situ through geo- archaeological works (e.g. Almadén de la Pla...

Characterisation and Historical Quarries Location of Marbles from Guarrazar Arc...
Freire-Lista, David; Santos, José Francisco; Lopes, LuísMarbles have been used for the beautification of cities, temples and palaces throughout history. These building stones are compositionally analogue but show differences in texture and colour that can be associated with some petrographic and petrophysical properties, which makes possible to identify their origin. A variety of building marbles from Guarrazar archaeological site (Toledo, Spain) was investigated. T...
