This study investigates the potential for mineral carbonation of carbon dioxide (CO2) in plutonic basic rocks through a series laboratory experiments conducted two stages, under pressure (8 MPa) and temperature conditions (313.15 K) akin to those near CO2 injection well. Stage-I facilitated dissolution with crushed rock exposed supersaturated seawater (0.6 M), while Stage-II promoted cubic specimens contact subsaturated (0.1 M). A multi-analytical approach was employed track mineralogical...
During the Islamic period, ceramic workshops were commonly established in settlements throughout Gharb al-Andalus region (Western Iberia at time), to produce ceramics for local supply. Along middle valley of Tagus river (i.e., nowadays central Portugal), hundreds sherds, either glazed or common wares, recovered over different archaeological excavations. At site Serradinho, located Muge (Municipality Salvaterra de Magos, Santarem District, a fortuitous finding was unearthed during...
This study examines the sourcing of amphibolite polished stone artifacts from Late Neolithic–Chalcolithic contexts at Perdigões archaeological complex. The analyzed alongside geological samples collected broader region, for straightforward comparison. Petrographic, mineralogical, and geochemical analyses reveal a clear mismatch between within 60-kilometer radius, indicating that raw materials were not obtained nearby sources.
The potential for mineral carbonation of CO2 in plutonic mafic rocks is addressed through a set laboratory experiments on cumulate gabbro and gabbro-diorite specimens from the Sines Massif (Portugal). were conducted an autoclave, maximum 64 days, using supersaturated brine under pressure temperature conditions similar to those expected around injection well during early-phase injection. Multiple techniques mineralogical geochemical characterization applied ante- post-carbonation experiments....
The potential for mineral carbonation of carbon dioxide (CO2) in a plutonic mafic rock is addressed this work through set laboratory experiments on gabbro-anorthosite sample from the Torrão - Odivelas Massif (Portugal). experiment was conducted two stages under pressure (8 MPa) and temperature (313.15 K) conditions similar to those expected around CO2 injection well. Stage-I simulated dissolution conditions, with crushed (1–3 mm) exposed 30 days supersaturated seawater (0.576 M). Stage-II...
This article describes the screening, ranking and characterization of ultramafic mafic rocks in southern Portugal for mineral carbonation as an alternative to conventional CO2 storage sedimentary rocks. A set criteria including mineralogy, structure, surface area, distance sources, expected volume, socioeconomic conditions was applied screen rock massifs Alentejo region, Portugal. Ranking indicated that plutonic Sines Torrão‒Odivelas were most promising. made massif, a subvolcanic massif...
This study focuses on the analysis of Islamic ceramics from Alcaçova Santarém, Portugal. To establish ceramic raw material provenance and technology, a set materials was sampled compared with archaeological ceramics. Raw were dry sieved to increase clay content, reconstruct ceramist homogenization process, evaluate chemical mineralogical variation. Results showed that two selected for local production, whereas some artefacts imported.
Anthracological analyses of charcoal samples retrieved from Pit 16 Perdigões (Reguengos de Monsaraz, Portugal), a secondary deposition cremated human remains dated back to the middle 3rd millennium BC, enabled identification 7 different taxa: Olea europaea, Quercus spp. (evergreen), Pinus pinaster, Fraxinus cf. angustifolia, Arbutus unedo, Cistus sp. and Fabaceae. All taxa are characteristic both deciduous evergreen Mediterranean vegetation, this data might indicate that gathering woods...
In this work, a protocol of partially invasive sampling for the archaeometric characterization ancient mortars from little Roman Bath Nora (Sardinia, Italy) is presented. Optical microscopy and different analytical techniques such as X-ray diffraction, fluorescence, thermo-gravimetric analysis, physical/mechanical tests have been carried out on mortars. These analyses were performed to investigate chemical composition, alteration products, binder pozzolanic activity. An innovative method...
Abstract A multidisciplinary approach has been applied to investigate the production technology of a collection copper-based artefacts found during archaeological excavation campaigns carried out in Almohad neighbourhood Mārtulah, Islamic name modern Mértola (South Portugal). In stark contrast other materials same site such as common and finely decorated pottery, glass, bone artefacts, metal objects have received less attention despite high number recovered. This study focuses on chemical...
Abstract In this article, the archaeological and archaeometrical study of several roof tiles bricks retrieved at Etruscan Domus dei Dolia is presented. The located in Etrusco-Roman neighbourhood (Hellenistic – Late Republican periods, third–first centuries BC) ancient city Vetulonia (central Italy), area Poggiarello Renzetti . main goals were to establish characteristics raw material/s used their production, possible provenance, technology applied, get insight regarding production...
The Etruscan Domus of the Dolia remained hidden until 2009, when archaeological excavations began in Etruscan–Roman district Vetulonia (Southern Tuscany). Based on classification materials recovered, destruction and city was traced back to 1st century BC. highly various precious recovered inside revealed richness building its inhabitants. With this study, we present anthracological analyses from Dolia. Wood charcoals were different house rooms, which had functions based evidence. tree...
In the present study an archaeometry programme has been developed on a limited number of coarse wares, monochrome, and bichrome glazed ceramics retrieved in cities Évora, Mértola, Silves, located Western Iberia, Portugal (Gharb al-Andalus during Islamic period). The goals were to shed light provenance, technology, trading, glaze technology applied. For this purpose, multi-analytical approach was employed characterize ceramic pastes glazes using optical microscopy (OM), X-ray diffraction...
Resumo:Fragmentos cerâmicos vidrados e não vidrados, recuperados nas cidades de Évora, Mértola Silves foram objeto dum estudo morfo-funcional, considerando as características tipológicas decorativas observadas no Gharb al-Andalus. As possíveis produções locais não-locais em cada cidade identificadas por petrografia dos corpos cerâmicos, a composição mineralógica da pasta cerâmica geologia local. Como resultado abordagem proposta, é sugerido uma cronologia, entre os séculos X meados do século...
Cacela-a-Velha, located on a cliff the Algarve coast, had castle in Islamic medieval period with jurisdiction over territory of Baixo Guadiana. Clay deposits were an important raw material region’s pottery production, which dates back to Roman times, impact settlement subsequent times. Archaeological excavations carried out Cacela since 1989 have brought together collection around 25,000 ceramic pieces. Archeology motivated development interdisciplinary project, aim understanding how...
The Bell Beaker site near Brodek u Prostějova (Czechia) has yielded remains of a large timber construction accompanied by four symmetrical ritual deposits with numerous artefacts, including more than fifty ceramic vessels. Their decoration consists incised patterns, in nineteen cases preserved white inlaid incrustations. To investigate the social relations at this extraordinary site, multi-analytical and micro-destructive approach was employed to determine provenance technology pottery...
Do conjunto de intervenções arqueológicas ocorridas na área urbana Évora nos últimos trinta anos resultou um espólio cerâmico bastante significativo e heterogéneo cronologia medieval-islâmica (entre os séculos VIII XII). Neste destaca-se uma tigela com técnica ornamental até agora nunca documentada Península Ibérica. Ao expor discutir resultados do estudo estilístico analítico efetuado sobre a peça, revelou-se originalidade da decorativa, caracterizada por cor base castanho/castanho escuro...
