Marmora del anfiteatro de Itálica. Identificación arqueométrica: un ejemplo del...
Ontiveros Ortega, Esther; Moreira, Noel; Lopes, Luis; Loza Azuaga, Maria Luisa; Beltran Fortes, JoseEste capítulo tiene como objetivo conocer la procedencia geológica de algunos mármoles usados originalmente en el anfiteatro de Itálica (Santiponce, Sevilla). Los estudios de procedencia de materiales geológicos en yacimientos arqueológicos constituyen una línea de investigación que se ha desarrollado ampliamente en las últimas décadas en España, poniendo de manifiesto que, junto a materiales pétreos de importa...
Laboratory experiments and modelling of the geochemical interaction of a gabbro...
Berrezueta, Edgar; Moita, Patricia; Pedro, Jorge; Abdoulghafour, Halidi; Mirão, José; Beltrame, Massimo; Barrulas, Pedro; Araújo, AlexandreThe potential for mineral carbonation of carbon dioxide (CO2) in a plutonic mafic rock is addressed in this work through a set of laboratory experiments on a gabbro-anorthosite sample from the Torrão - Odivelas Massif (Portugal). The experiment was conducted in two stages under pressure (8 MPa) and temperature (313.15 K) conditions similar to those expected around a CO2 injection well. Stage-I simulated dissolu...
Comparative multi-analytical study to forecast marble and limestone structural ...
Pires, Vera; Sitzia, Fabio; Lisci, Carla; Mirao, José; Lopes, LuisFor centuries, natural stone has adorned facades, evolving from thick construction elements to thin cladding applications due to advanced cutting technologies. However, durability issues, especially in thin marble cladding, have surfaced after approximately 50 years of installation, as seen in iconic structures like the Amoco Building and Finlandia Hall. This study focuses on characterizing Carrara and Ruivina ...
Almadén de la Plata marble: a Heritage Stone Proposal
Lopes, Luis; Beltran, José; Ontiveros, Esther; Moreira, Noel; Loza, Maria Luisa; Carneiro, AndréAlmadén de La Plata marble is located in Ossa-Morena Zone (Iberian Massif) and generated through Variscan metamorphism of Cambrian limestones, being exploited during the Roman period. They were used in a wide variety of ways, such as architectural elements and decoration, statuary, and epigraphic monuments. The quarries for these marbles did not reach the dimensions found in other places (i.e., Vila Verde de Fi...
A Novel Approach for the Reuse of Waste from the Extractive and Processing Indu...
Afonso, Paula; Pires, Vera; Faria, Paula; Azzalini, Antônio; Lopes, Luis; Mourão, Paulo; Martins, RubenThis paper discusses the historical use of natural stone for various purposes and highlights the substantial waste generated by quarries and stone processing plants in modern industrialized production. These waste materials are typically categorized into unused rock and sludges from processing. This accumulation of waste presents a global environmental challenge and a financial burden for the stone industry. In...
Mortar Based on Sludge from Carbonate Dimension Stone Processing Industry - an ...
Afonso, Paula; Azzalini, Antônio; Faria, Paula; Lopes, Luis; Martins, Ruben; Mourão, Paulo; Pires, VeraThe extractive and processing of carbonate dimension stone, such as limestone and marble is particularly important in Portugal. The main extractive centres are in the marble triangle formed by Estremoz, Borba, Vila Viçosa and also the Estremenho Limestone Massif. The large number of quarries and processing units, given the techniques used, both in extraction and processing, and the high-quality criteria require...
Marble facades structural decay due to bowing – A comprehensive review
Pires, Vera; Lisci, Carla; Sitzia, Fabio; Lopes, Luis; Mirao, Jose; Dias, luis; neves, samuelNatural stone has been used in façades for centuries. Initially, stone elements were rather thick when used as construction elements, and the durability was appropriate. Scientific research on the properties of marble began in the late 19th century. In the following years, the thicknessof naturalfacadestonesdecreasedfromover1000mm(asinconstructionelements) to20-50mm (incladdingapplications)becauseofnewcuttingte...
Avanços no projeto LouMu – Muografia para levantamentos geofísicos
Teixeira, Pedro; Blanco, Alberto; Caldeira, Bento; Tomé, Bernardo; Alexandre, Isabel; Matos, João; Silva, Jorge; Borges, José Fernando; Cazon, LorenzoO Projeto LouMu é uma colaboração em curso entre o Laboratório de Instrumentação e Física Experimental de Partículas, o Instituto de Ciências da Terra – Universidade de Évora e o Centro Ciência Viva do Lousal, contando ainda com o apoio do Laboratório Nacional de Energia e Geologia. O objetivo é explorar o potencial da técnica de muografia na Mina do Lousal, com a finalidade de criar as condições para a utiliza...
Portuguese limestones from the Middle Jurassic of the MCE candidate for heritag...
Lopes, Luis; Carvalho, JorgeABSTRACT: The Monastery of Alcobaça (1152 AD), the Convent of Christ in Tomar (1160 AD) and the Monastery of Batalha (1386 AD), are classified as UNESCO World Heritage Sites, having in common the construction materials that built them - Limestones from the Middle Jurassic of the Estremenho Limestone Massif (MCE). The use of these rocks, first as a structural element and later as an ornamental rock, continues to...
Middle Jurassic dinosaur footprints from the Serras de Aire and Candeeiros [Res...
Lopes, Luis; Sá, Artur Abreu; Carvalho, Jorge; Mergulhão, Lia; Cachão, Mário; Galopim de Carvalho, António MarcosABSTRACT: The Dinosaur Footprints Natural Monument of Ourém/Torres Novas, known as Galinha quarry, and the Vale de Meios quarry, are located in the Serras de Aire e Candeeiros Nature Park (Central Portugal). They are two geosites, duly geoconserved, of recognized international scientific value, due to its exceptionality regarding to the age, size, and quality of preservation of ichnites. Both quarries are locat...
