- Natural Stones from Portugal : Proposal for harmonizing Commercial NamesPublication . Carvalho, Jorge; Carvalho, Cristina Isabel Paulo; Lopes, Luis; Silva, António; Santos, Catarina; Sousa, Luís; Martins, Ruben; Marques, CéliaABSTRACT: Over the years, the Portuguese Geological Survey – LNEG, has been dedicated to the characterization of Portuguese natural stones. Today, a newly updated LNEG web portal contains information on 149 natural stones, which are known by their unique trade names. Many of these names integrate the EN 12440 - Natural Stone - Denomination Criteria standard, but others do not. Furthermore, there many other names used to identify natural stones that are traded today and that do not integrate the LNEG web Portal or the EN 12440. This work presents a harmonization proposal for the commercial denomination of the Portuguese natural stones. It is a working basis for a final list that must be submitted to ISO/Technical Committee 118 – Natural Stones.
- A Pedra Natural Portuguesa : Proposta de harmonização de Designações ComerciaisPublication . Carvalho, Jorge; Carvalho, Cristina Isabel Paulo; Lopes, Luis; Silva, António; Santos, Catarina; Martins, Ruben; Marques, Célia; Sousa, LuísRESUMO: No início dos anos 80 do século passado, o LNEG – Laboratório Nacional de Energia e Geologia (Serviços Geológicos de Portugal), através das suas instituições públicas antecessoras, deu início à caracterização e à inventariação das rochas ornamentais extraídas em Portugal. Deste trabalho inaugural resultou o primeiro Catálogo de Rochas Ornamentais Portuguesas, publicado em 4 volumes entre 1983 e 1994, complementado por 8 fichas técnicas editadas entre 1995 e 2000. Em 2002, a 1ª versão em formato digital do catálogo começou a ser desenvolvida, tendo sido incluída no site do LNEG como o Portal das Rochas Ornamentais Portuguesas – ROP. Foi atualizado em 2021 (https://geoportal.lneg.pt/pt/bds/rop/), englobando toda a informação contida no catálogo, além de novas funcionalidades como a “pesquisa por critérios”, tais como a designação comercial, o município de exploração, a cor, assim como diversas características tecnológicas. Ao longo dos anos, novas pedras foram acrescentadas ao ROP, que atualmente contém a informação relativa a 149 litótipos comerciais portugueses.
- Portuguese limestones from the Middle Jurassic of the MCE candidate for heritage stone [Resumo]Publication . 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 today. In fact, considering the volumes of ornamental rock exploited in Portugal, these rocks have the highest values and are exported annually to more than a hundred countries, playing a decisive role in placing Portugal in the top ten world exporters of ornamental rocks.
- Middle Jurassic dinosaur footprints from the Serras de Aire and Candeeiros [Resumo]Publication . 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 located in limestones of the Serra de Aire Formation (Bathonian, Middle Jurassic) (Azerêdo 2007). The Galinha quarry preserves 20 trails with sauropod footprints, in an excellent state of conservation, and it is possible to observe finger marks and a ridge formed by the sediment that was removed under the weight of the animal. This deposit has some of the oldest and longest sauropod tracks known in the world (up to 147 m long) and allows to obtain a dynamic image of the locomotion of these sauropods (Santos et al 2009). The Vale de Meios quarry preserves more than 700 theropod tracks. They are organized in at least 80 unidirectional trackways, arranged in a bimodal orientation pattern (W/NW and E/SE). Paleoenvironmental studies in this quarry indicates an inter-tidal flat located at the margin of a coastal barrier (Razzolini et al 2016).
