Summary: In this study, a pilot study integrating automated drill core scanning technology based on simultaneous X-ray computed tomography (XCT) and X-ray fluorescence (XRF) analyses was conducted. The results showed that this technique provides valuable information on 3-D rock textures and structures, chemical composition, and density, which is useful for mineral exploration and research.

Summary: A series of quantitative micro X-ray fluorescence analyses were conducted on different parts of archaeological copper alloys from Iran to evaluate the feasibility of quantitative XRF data for ancient copper alloy classification. The study found that corroded surfaces may provide misleading information, but areas with the lowest tin concentration may represent the closest compositional data to the absolute quantity of other elements. The quantitative mu-XRF data from stripped-patina surfaces and polished cross sections showed comparable results with ICP-OES data and can be confidently utilized for determining the diversity and technology of ancient copper alloys.

Summary: This study improved the spatial resolution of micro-X-ray fluorescence analysis through oversampling and image restoration techniques. Different algorithms were tested, and the Richardson-Lucy method showed the best results. The blind deblurring method did not significantly improve the resolution. The technique also showed promising results in reducing resolution variations caused by polychromatic X-rays in rock samples.

Summary: The combination of brilliant liquid metal jet sources (LMJS) and polycapillary lenses can significantly improve the excitation efficiency of traces of transition metals by micro-X-ray fluorescence spectroscopy (mu XRF) in the laboratory. By optimizing the parameters of polycapillary lenses and energy dependent influence of the source spot size, a significant increase in excitation efficiency for specific elements can be achieved, resulting in clearer and more detailed analysis results.

Summary: The largest lake in Europe was the Neogene Lake Pannon, and its maximum extent was during the Tortonian Thermal Maximum. A detailed lake record from a 60-meter-long core of Lake Pannon provides information on its environmental development during its maximum extent, including stable sedimentation, low surface productivity, and bottom-water anoxia.

Summary: Sarissa, an important city of the Hittite Empire, believed to be destroyed by fire or battle, had its mudbricks deformed. XRF analysis was used to analyze the compounds and oxides of the mudbricks, comparing them with geological formations. SEM and EDX analysis helped estimate firing temperatures and elemental distribution, showing potential formation of gypsum due to glass melting and low viscosity bubble formation.

Summary: Metal additive manufacturing enables the production of high value and high performance components through layer-by-layer fabrication. A new technique called vat photopolymerization (VP) is introduced, which allows the production of metals and alloys with microscale resolution. This technique does not require reoptimization of resins and curing parameters for different materials, enabling quick fabrication and compositional tuning.

Summary: This study examined the production technology of Egyptian blue through the investigation of an unsuccessfully produced pellet from the Hellenistic production site of Kos in Greece. The use of inappropriate starting materials with unusually high iron content, rather than inadequate firing temperatures, may have led to the unsuccessful production. The results highlight the intertwined relationship between the production of Egyptian blue and metallurgy.

Summary: The variation of sulphur in stalagmites can be used to infer past volcanic activities, anthropogenic pollution, and climate change. Synchrotron radiation micro X-Ray fluorescence (SR-XRF) microprobe and benchtop micro-XRF are effective tools for analysing and imaging sulphur in stalagmites with high resolution.

Summary: The study of terraced agricultural soils in the high-altitude eastern margin of the Atacama Desert in northern Chile reveals intentional soil changes through terracing, removal of soil rock fragments, and probable fertilization. Agricultural soils have anthropogenic horizons ranging from 16 to 54 cm thick, with higher phosphorus levels indicating enrichment from fertilization. Initial studies suggest that agriculture in this region was sustainable in terms of conserving soils and maintaining or possibly improving soil productivity over centuries.

Summary: This research conducted a sensitivity analysis of response spectrum values for various physical earthquake parameters in order to generate synthetic seismograms consistent with expected seismicity in north Chile. The study found that rupture directivity and slip rise time have significant effects on seismic response, with shorter slip rise times leading to higher seismic demands in long period structures.

Summary: The stable isotope analyses on camelid bone remains in Chile revealed changes in isotopic values associated with environmental transformations during the Early and Middle Archaic period. However, the high size variability within the large camelid group made it impossible to establish the use of specific herding areas.

Summary: Aerial archaeology has been rarely developed in Galicia in the past due to several reasons, but the increasing availability of open access datasets is beginning to change this. Recent discoveries of potential archaeological features around a large group of castros in A Coruna and Lugo provinces provide strong arguments for the development of future projects in this direction, utilizing bespoke platforms, sensors, and imaging for profitable results in the near future.

Summary: Studies of archaeological goldwork in the south-central Andes region have often focused on visually striking artefacts, ignoring the potential complexity and cultural significance of gold technology in the area. Using a life-history approach, this study examines gold and silver objects from northern Chile through chemical and microscopic analyses. The results reveal diverse compositions, techniques, and skill levels, suggesting that gold artefacts were imported from various areas in the south-central Andes and used in different ways, including small-scale production and modifying imported objects. This research highlights the significance of integrative approaches in understanding the cultural context and production methods of archaeological goldwork.

Summary: This study presents new archaeological evidence from the Pedernales Valley in the southern puna of Chile, suggesting that the coastal Huentelauquen groups explored and inhabited the Andean highlands between approximately 10,151 and 9,695 years ago. The findings contribute to our understanding of the diversity of environments utilized by coastal populations during the Early Holocene, as well as their mobility and settlement strategies.

Summary: This study assesses the potential of crustal faults in the northern Chile outer forearc to experience reactivation due to stress perturbations induced by the interseismic and coseismic phases of the megathrust earthquake cycle. The results show that both interseismic and coseismic stages can lead to fault reactivation, with each stage favoring specific fault types. A great megathrust earthquake in the area could promote the reactivation of most of the upper crustal faults, increasing the seismic hazard in the region.

Summary: This article presents the findings of interdisciplinary research conducted in Quebrada Pedernales in the highlands of northern Chile. The investigations revealed diverse pre-Hispanic evidence, suggesting continuous occupation between certain time periods. The analyses of various data indicate the existence of mobility circuits between the coast and the puna, coinciding with improved environmental conditions and increased aridity. The study also documents the impact of extreme aridity on human settlement and mobility.

Summary: This article presents the results of excavations at the Infieles-1 site, located at 3529 m. a.s.l. in the Salar de Infieles (25 degrees S), highlands of the Chile's southern Puna ecoregion. An initial human occupation was discovered, consisting of lithic wasted-flakes and knapping debris, an ultra-marginal andesite side-scraper, vicuna bone fragments and traces of red mineral pigment. This is the first human occupation recorded in the southern Puna, associated with more favorable environmental conditions during the late Central Andean Pluvial Event II (CAPE II).
