Complexities and span of crystallization ages of a non-foliated Svecofennian granite pluton

Upper-intercept U-Pb ages (TIMS) of two non-foliated I-type granites are 1887 ± 20 Ma (part of a granodiorite-granite sequence) and 1881 ± 2 Ma (leucogranite with transitions into pegmatite). A non-foliated S-granite, which according to field observations, is younger than the two I-granites, occurs within the same composite pluton. Zircons of this granite are heterogeneous and contain abundant cor

Experimental Analysis of Multipath Characteristics in Indoor Distributed Massive MIMO Channels

Distributed multiple-input multiple-output (MIMO), also known as cell-free massive MIMO, has emerged as a promising technology for sixth-generation (6G) wireless networks. This letter introduces an indoor channel measurement campaign designed to explore the behavior of multipath components (MPCs) in distributed MIMO channels. Fully coherent channels were measured between eight distributed uniform

Taxonomic diversity in the global wheat phyllosphere mycobiome – a meta analysis

Wheat (Triticum aestivum L.) is a major crop grown on all continents. Due to environmental concerns, it is desirable to reduce the inputs of both chemical pesticides and inorganic fertilizers. However, yield reduction must be expected when switching to low-input systems. To mitigate such losses, the use of natural or introduced microbiomes may provide the key to maintaining sustainable yield. Phyl

The invention pertains to a process for preparing a random co-poly(urethane-carbonate) comprising reacting a 6-membered di-cyclic carbonate with a polyamine via a ring- opening polymerization (ROP) by catalytic control for carbonate unit formation, in the presence of a catalyst, through a ring-opening polymerization reaction. Also, the invention pertains to a random co-poly(urethane-carbonate) bei

Forensic differentiation of Malaysia biodiesel and illicit fuels using GC-FID and GC–MS techniques

Illegal, unreported, and unregulated (IUU) fishing poses a serious threat to marine biodiversity and economic stability, particularly in coastal nations like Malaysia, where the smuggling of government-subsidized fuel is often linked to IUU activities. This study presents a forensic approach using gas chromatography-flame ionization detection (GC-FID) and gas chromatography-mass spectrometry (GC–M

Geochemistry of greenstones in theTasiusarsuaq terrane, southern West Greenland

Tonalite-trondhjemite–granodiorite (TTG) gneisses and melanocratic to ultramafic greenstones dominate the Archaean basement of southern West Greenland. The greenstones are likely to represent different original environments, which is important as the mineral deposits they may host depend on this. For example, massive sulphide deposits associated with gold and base metals are commonly volcanogenic,

Provenance of Cretaceous and Paleocene sandstones in the West Greenland basins based no detrital zircon dating

The extensive and very deep ?Jurassic/Cretaceous–Palaeogene sedimentary basins offshore West Greenland have a significant petroleum exploration potential. This is particularly true for the offshore region west of Disko and Nuussuaq where a live petroleum system has been documented for many years. At present, stratigraphic knowledge in this area is almost nonexistent and analogue studies from onsho

A well-preserved bimodal Archaean volcanic succession in the Tasiusarsuaq terrane, South-West Greenland

During the field campaign in the Nuuk region, one of the objectives was to describe Archaean primary geological environments (Hollis et al. 2006). On Nunatak 1390, which is part of the Tasiusarsuaq terrane (Figs 1, 2), a bimodal volcanic succession is preserved and interpreted as former ocean floor. The field investigation included geological mapping and sampling of the volcanic sequence comprisin

Geological observations in the southern West Greenland basement from Ameralik to Frederikshåb lsblink in 2008

In 2008, the Geological Survey of Denmark and Greenland began a project in collaboration with the Bureau of Minerals and Petroleum of Greenland with the aim to publish a web-based, seamless digital map of the Precambrian bedrock between 61°30´ and 64°N in southern West Greenland. Such a map will be helpful for the mineral exploration industry and for basic research. Producing an updated digital ma

The 7Be(d, α)5Li(p α) and 7Be(d, p)8Be*(p 7Li) reactions at 5 MeV/u

The 7Be(d, α)5Li and 7Be(d, p)8Be*(p 7Li) reactions are studied at 5 MeV/u in the context of the cosmological lithium problem. This work aims to probe the contribution of 7Be destruction mechanisms, particularly through channels that populate intermediate unbound states of 5Li and 8Be. The contribution of 7Be(d, α)5Li(p α) reaction is separated from the 7Be(d, p)8Be*(2α) reaction. The 7Be(d, p)8Be

Ion probe dating of a migmatite in SW Sweden : The fate of zircon in crustal processes

A migmatitic orthogneiss in the Western Segment in the Sveconorwegian Province of the Baltic Shield was dated using the ion-probe U-Pb method on zircon grains, which were also analysed for rare earth elements. Mesosome zircons have 1.605±0.010Ga magmatic cores, which places the gneiss protolith in the same 1.61-1.59Ga time bracket as continental arc-related gneisses, abundant in this part of the S

Subgrain-scale decoupling of Re and 187Os and assessment of laser ablation ICP-MS spot dating in molybdenite

Reproducibility of Re-Os molybdenite ages depends on sample size and homogeneity, suggesting that Re and Os are decoupled within individual molybdenite crystals and do not remain spatially linked over time. In order to investigate the Re-Os systematics of molybdenite at the subgrain (micron) scale, we report LA-ICP-MS Re-Os ages for an Archean molybdenite crystal from Aittojärvi, Finland, analyzed

187RE-187OS evidence for crustal lenses of Svecofennian age within the Mylonite Zone, SW sweden

Re and Os concentrations and isotopic composition were analysed in four ultramafic cumulates from the Kedum tectonic lens within the Mylonite Zone, SW Sweden. An 1887±36 Ma isochron is obtained for six samples and interpreted to date the Kedum body. This is significantly older than the -1600-1700 Ma surrounding crust and the first rocks of Svecofennian age west of the Trans Scandinavian Igneous Be

Feasibility study of the internet-based intervention “Strategies for Empowering activities in Everyday life” (SEE 2.0) for use by people with chronic diseases and long-term disorders in healthcare: A study protocol.

Introduction: Proactive and easily accessible interventions are needed to support people with long-term health conditions who experience limitations in activities of everyday life. However, there is a lack of interventions that promote self-management skills that prevent deterioration and improve health. The internet-based programme 'Strategies for Empowering Activities in Everyday Life' (SEE) sup

Sensory pollutants have negative but different effects on nestbox occupancy and breeding performance of a nocturnal raptor across Europe

Anthropogenic noise and artificial light at night (ALAN) are expanding globally, acting as pervasive sensory pollutants that can disrupt wildlife behaviour and reproduction. While most research has focused on diurnal species, the effects of these pollutants on the ecological response of nocturnal predators remain poorly understood. Using data from nine European countries, we investigated the effec

The relationship between experienced losses and damages, risk tolerance and livelihood thresholds in the East Gippsland, Australia, farming sector

Losses and damages are residual impacts of climate change that occur despite mitigation and adaptation actions. Losses and damages are borderless, albeit experienced differently between and within countries. Although Australia is a high-income country, recent losses and damages have been particularly severe. Over the last eight years, farmers in East Gippsland, Victoria, have been severely affecte

The remarkable Re-Os chronometer in molybdenite : How and why it works

The Re-Os (rhenium-osmium) chronometer applied to molybdenite (MoS2) is now demonstrated to be remarkably robust, surviving intense deformation and high-grade thermal metamorphism. Successful dating of molybdenite is dependent on proper preparation of the mineral separate and analysis of a critical quantity of molybdenite, unique to each sample, such that recognized spatial decoupling of 187Re par

Dating mafic-ultramafic intrusions by ion-microprobing contact-melt zircon : Examples from SW Sweden

Zircons from anatectic melts of the country rocks of three Proterozoic mafic-ultramafic intrusions from the Sveconorwegian Province in SW Sweden were microanalyzed for U-Th-Pb and rare earth elements. Melting and interaction of the wall rocks with the intrusions gave rise to new magmas that crystallized zircon as new grains and overgrowths on xenocrysts. The ages of the intrusions can be determine
