Abstract:
The rocks of the Sobsky complex, composing the bulk of the Sobsky batholith in the Polar Urals, contain mafic inclusions. The geological, petrographic and petro‐geochemical data show that the mafic inclusions of the Sobsky rocks belong to igneous formations, which are similar in their characteristics to autoliths. According to all the characteristics, these are the structures non‐contrasting to host rocks and having different structural‐textural features, a more basic composition of minerals and a more basic composition of rocks. The contact with the rocks of the complex is sharp and clear. The rocks of the complex in contact with autoliths are medium‐grained massive diorite rocks, quartz diorites, tonalites, mafic inclusions rocks – fine‐grained gabbros, gabbro‐diorites, and diorites. Isotopicgeochemical (U‐Pb, SIMS) data on zircons from the mafic inclusions suggest that their age is close, within the error limits, to the age of zircons from the enclosing Sobsky complex rocks.

Abstract:
Mafic granulites (metamorphosed tholeite-komatiite volcanic rocks) represent the inclusions in gneissenderbite of the Bug complex (southwest of the Ukrainian shield). The studied mafic inclusion has two zircon generations of magmatic origin that yield, respectively, SHRIMP zircon U–Pb ages of 3628±58 Ma and 2845±65 Ma. The first age is the oldest date the earliest stage of basic magmatism on the Ukrainian shield. The age of the second zircon is interpreted as a result of partial melting, synchronous with the metamorphism in the area.

Abstract:
Abstract Understanding the origins of the mantle melts that drive voluminous silicic volcanism is challenging because primitive magmas are generally trapped at depth. The central Taupō Volcanic Zone (TVZ; New Zealand) hosts an extraordinarily productive region of rhyolitic caldera volcanism. Accompanying and interspersed with the rhyolitic products, there are traces of basalt to andesite preserved as enclaves or pyroclasts in caldera eruption products and occurring as small monogenetic eruptive centers between calderas. These mafic materials contain MgO-rich olivines (Fo79–86) that host melt inclusions capturing the most primitive basaltic melts fueling the central TVZ. Olivine-hosted melt inclusion compositions associated with the caldera volcanoes (intracaldera samples) contrast with those from the nearby, mafic intercaldera monogenetic centers. Intracaldera melt inclusions from the modern caldera volcanoes of Taupō and Okataina have lower abundances of incompatible elements, reflecting distinct mantle melts. There is a direct link showing that caldera-related silicic volcanism is fueled by basaltic magmas that have resulted from higher degrees of partial melting of a more depleted mantle source, along with distinct subduction signatures. The locations and vigor of Taupō and Okataina are fundamentally related to the degree of melting and flux of basalt from the mantle, and intercaldera mafic eruptive products are thus not representative of the feeder magmas for the caldera volcanoes. Inherited olivines and their melt inclusions provide a unique “window” into the mantle dynamics that drive the active TVZ silicic magmatic systems and may present a useful approach at other volcanoes that show evidence for mafic recharge.

Abstract:
Chromian spinels occur in mafic–ultramafic inclusions in the Sublayer of the Sudbury Igneous Complex (SIC) as well as in mafic–ultramafic rocks in the immediate footwall of the Sublayer. The host rocks are pyroxenite and melanorite with minor dunite, harzburgite, and melatroctolite. As common accessory phases in these rocks, the chromian spinels display euhedral or subhedral forms and are included in olivine and orthopyroxene. Chromian spinel grains generally have ilmenite lamellae and contain abundant inclusions (zircon, olivine, diopside, plagioclase, biotite, and sulfide). All the chromian spinels have similar trace element abundances and are rich in TiO2 (0.5–15 wt.%). They have constant Cr# (100Cr/(Cr + Al)) (55–70) and exhibit a continuum in composition that traverses the normal fields of spinels in a Al–(Fe3+ + 2Ti)–Cr triangular diagram. This continuum extends to that of the composition of chromian magnetite in the host norite matrix to the mafic–ultramafic inclusions. This continuum in composition of the spinels suggests that the noritic matrix to the Sublayer formed from the same magma as the inclusions. A positive correlation between the Cr and Al contents of the spinels was probably produced by dilution of these elements by Fe3+ contributed, perhaps, by a plagioclase-saturated melt. Zircon inclusions in a chromian spinel grain reflect incorporation of crustal, felsic materials into the magma before crystallization of chromian spinel. The chemical characteristics and mineral inclusions of the spinels suggest that the Sublayer formed in response to magma mixing. It is suggested that subsequent to the formation of the crustal melt, mantle-derived high-Mg magmas mixed vigourously with this and generated the magmatic sulfides that eventually formed the Ni – Cu – platinum-group elements sulfide ore deposits. Some of the early crystallization products of the high-Mg magma settled to the chamber floor, where they partially mixed with the crustal melt and formed the mafic–ultramafic inclusions and footwall complexes.

Abstract:
AbstractHere we present a study on the quenchability of hydrous mafic melts. We show via hydrothermal experiments that the ability to quench a mafic hydrous melt to a homogeneous glass at cooling rates relevant to natural samples has a limit of no more than 9 ± 1 wt% of dissolved H2O in the melt. We performed supra-liquidus experiments on a mafic starting composition at 1–1.5 GPa spanning H2O-undersaturated to H2O-saturated conditions (from ~1 to ~21 wt%). After dissolving H2O and equilibrating, the hydrous mafic melt experiments were quenched. Quenching rates of 20 to 90 K/s at the glass transition temperature were achieved, and some experiments were allowed to decompress from thermal contraction while others were held at an isobaric condition during quench. We found that quenching of a hydrous melt to a homogeneous glass at quench rates comparable to natural conditions is possible at water contents up to 6 wt%. Melts containing 6–9 wt% of H2O are partially quenched to a glass, and always contain significant fractions of quench crystals and glass alteration/devitrification products. Experiments with water contents greater than 9 wt% have no optically clear glass after quench and result in fine-grained mixtures of alteration/devitrification products (minerals and amorphous materials). Our limit of 9 ± 1 wt% agrees well with the maximum of dissolved H2O contents found in natural glassy melt inclusions (8.5 wt% H2O). Other techniques for estimating pre-eruptive dissolved H2O content using petrologic and geochemical modeling have been used to argue that some arc magmas are as hydrous as 16 wt% H2O. Thus, our results raise the question of whether the observed record of glassy melt inclusions has an upper limit that is partially controlled by the quenching process. This potentially leads to underestimating the maximum amount of H2O recycled at arcs when results from glassy melt inclusions are predominantly used to estimate water fluxes from the mantle.

Abstract:
Melt inclusions record valuable information about pre-eruptive melt volatile concentrations. However, a vapor bubble commonly forms in inclusions after trapping, and this decreases the dissolved CO2 concentration in the trapped melt. To quantify CO2 loss to bubbles, Raman spectroscopic analysis was used to determine the densities of CO2 vapor in the bubbles. The samples analyzed in this study are from two Cascade cinder cones near Mt. Lassen and two Mexican cinder cones (Jorullo, Paricutin). Using analyses of dissolved CO2 and H2O in the glass in the inclusions, the measured CO2 vapor densities were used to reconstruct the original dissolved CO2 contents of the melt inclusions at the time of trapping. The Raman-restored CO2 values are similar to restored CO2 values calculated using a model of cooling and olivine crystallization in the trapped melts.

Full text
Abstract:
Throughout its eruptive history, Mount Hood has produced compositionally similar calc-alkaline andesite as lava flows and domes near the summit and basaltic andesitic flows from flank vents. Found within the andesite are slightly more mafic inclusions that are compositionally similar to the host andesite (or host lavas); no inclusions were found in the flank lavas. Host lavas and inclusions have the following mineral assemblage: plag + opx ± cpx ± amp + oxides. Flank lava mineralogy is similar to the inclusions and host lavas, but since they are more mafic they contain olivine instead of amphibole. Average silica content among samples analyzed ranges from 57.6 to 62.7 weight percent; however the incompatible trace element composition is more variable at lower silica contents and becomes less variable at higher silica contents. In terms of incompatible trace element composition, the host lavas and inclusions are either depleted (no amp) or enriched (amp± cpx).

Abstract:
With the worldwide focus on financial inclusion to decrease poverty levels by banking the unbanked, understanding how to facilitate the banking of the previously unbanked in developing countries has become a globally topical issue. To contribute to this discussion from the perspective of Africa, the following paper endeavours to compute financial inclusion indices (FII) for 36 African countries. The paper leverages a model developed by Cámara and Tuesta (2014), using a two-stage Principal Component Analysis with definitions for financial inclusion variables from Sarma (2008). Upon computing the indices, we then endeavour to study the relationship between financial technology (fintech) and financial inclusion by running a regression analysis between fintech variables and the financial inclusion indices. As expected, we find that the highest financial inclusion levels are in the Southern and East African regions, with the lowest in Central Africa. The introduction of mobile money has had a significant impact on financial inclusion levels, particularly in East Africa. Our analysis also finds that the usage variable is critical in understanding the depth of financial inclusion. While this is so, there is still a great need for improvements across financial access, usage and availability in Africa. The regression analysis confirms this assessment, showing that overall, the use of mobile accounts has a positive and significant relationship with financial inclusion. At the same time, the use of digital payments for existing accounts also improves financial inclusion but to a lesser extent. The distinction between the impact of mobile banking and digital payments is an important one given that ownership of mobile banking increases the number of people with access to financial services while using digital payments merely deepens and enhances the usage of existing account holders. Macroeconomic factors of economic growth and banking sector development also are significant for financial inclusion, though to a lesser degree. This paper recommends the study of what impacts the sub-indices both positively and negatively, and how countries can maximise each sub-index, as it is an important focus area for policymakers who are looking to improve financial inclusion levels for their respective countries. We further recommend the development of a unified taxonomy on financial inclusion and its measurements. The role of policymakers would be to propel forward the formulation of this taxonomy, working with all the relevant stakeholders.

Abstract:
This thesis explores how coloniality of heritage, denial of racialization and forced passing impact Black women in Sweden. In response, it investigates practices of self-care adopted to buffer and cope with racism-related stress. Often, we connect self-care to spa-days, luxurious masks, and spoiling oneself as capitalism has translated self-care into one if its buzzword for people to consume. It is characterized by the privatization of wellbeing rather than a collective endeavor, which feeds into a capitalist agenda (Michaeli, 2017). Queering self-care and adopting self-care as self-preservation in the words of Audre Lorde (2017), provides a holistic embodiment of Black feminist thought, especially for us facing intersecting oppressions. Healing circles as a method for this research provides a safe-space where experiences can be shared over the commonality of being Black women in Sweden. Moreover, separatist settings are found to hold therapeutic value as they limit the risks of being alienated when talking about a common identity. In extension, the healing circles of this research explore how representation in media and art provide possibilities of being included in a global community as a response to not having access to physical affinity groups. Concludingly, I suggest how healing circles can and should be integrated in gender and feminist studies as an intersectional methodology that further develops the possibilities of not speaking for the Other.

Abstract:
ABSTRACT The Maksyutov complex is a mid- to late-Paleozoic high- to ultrahigh-pressure (HP-UHP) eclogite-bearing subduction zone terrane in the south Ural Mountains. Previous reports of radial fractures emanating from quartz inclusions in garnet, omphacite, and glaucophane, cuboid graphite pseudomorphs after matrix diamond, and microdiamond aggregates preserved in garnet identified by Raman spectroscopy indicate that parts of the complex were subjected to physical conditions of ∼600 °C and >2.8 GPa for coesite-bearing rocks, and >3.2 GPa for diamond-bearing rocks. Peak UHP eclogite-facies metamorphism took place at ca. 385 Ma, and rocks were exhumed through retrograde blueschist-facies conditions by ca. 360 Ma. Bulk analyses of 18 rocks reflect the presence of mid-oceanic-ridge basalt (MORB), oceanic-island basalt (OIB), and island-arc tholeiite (IAT) basaltic and andesitic series plus their metasomatized equivalents. To more fully constrain the petrotectonic evolution of the complex, we computed isochemical phase equilibria models for representative metabasites in the system Na2O-CaO-K2O-FeO-MgO-Al2O3-SiO2-H2O-TiO2 based on our new bulk-rock X-ray fluorescence (XRF) data. Both conventional Fe-Mg exchange thermometry and phase equilibrium modeling result in higher peak equilibrium temperatures than were previously reported for the complex. Pseudosection analysis provides minimum P-T conditions of 650–675 °C and 2.4–2.6 GPa for peak assemblages of the least retrogressed Maksyutov eclogites, whereas Fe-Mg exchange thermometry yields temperatures of 750 ± 25 °C for a pressure of 2.5 GPa. We interpret our new P-T data to reflect a thermal maximum reached by the eclogites on their initial decompression-exhumation stage, that defines a metamorphic field gradient; the relict coesite and microdiamond aggregates previously reported testify to pressure maxima that define an earlier prograde subduction zone gradient. The eclogitic Maksyutov complex marks underflow of the paleo-Asian oceanic plate and does not represent subduction of the Siberian cratonal margin.

The Mattawa domain, part of the Algonquin domain in Ontario, Canada, hosts some of the most deeply buried metamorphic rocks of this orogen. This high-grade metamorphic terrane consists of large areas of felsic orthogneiss and kilometer-sized mafic boudins. Dark-colored metabasite cropping out near Mattawa, Ontario, Canada, contains relict mineral assemblages and decompression textures indicative of high-pressure eclogite. Garnet porphyroblasts surrounded by plagioclase coronae are hosted in fine-grained symplectic intergrowths of diopside + plagioclase ± amphibole, which compositionally reintegrated into an omphacite composition (Na/[Na + Ca] ~0.5). Phase equilibria analysis revealed an eclogite-facies peak pressure of ~2 GPa at 850 °C. This temperature is consistent with the zirconium contents of rutile inclusions in garnet (up to 1725 ppm Zr). Despite high-temperature metamorphism, garnet growth zonation is partially preserved. Diffusion modeling of representative garnet profiles yielded a time scale of <0.1 m.y. for decompression from the peak pressure to ~1.2 GPa, suggesting an average exhumation rate of several decimeters per year. Decompression was followed by fast cooling within hundreds of thousands of years. Such fast decompression and cooling rates contrast with the protracted metamorphic evolution recorded in most of the Grenville orogen and likely resulted from local extrusion of lower-crustal material in response to localized extension during the early Ottawan stage. Since very few examples of Precambrian short-duration regional metamorphism have been documented, the fast decompression documented in this study provides valuable constraints for the geodynamic transition to a modern plate-tectonic regime.

Abstract:
Chapter 5 reviews the visual evidence on the basis of the stripped picture before the infilling of lost areas of paint. Pentimenti are apparent, most conspicuously in the repositioning of the thumb of the blessing hand. Infrared reflectography reveals detailed changes in the drapery and a few spolveri which indicate the use of a cartoon and shows the use of Leonardo’s hand-print method to soften the modelling of flesh. The vortex curls and the understated anatomy of the hands are typical of Leonardo’s post-1500 style, as is the insistent blurring of the contours of the face. The interlace pattern of the textile bands is founded on an angular geometry of the Islamic kind and reflects Leonardo’s visit to Venice in 1500. The transparent orb is of rock crystal and is marked by gaps or ‘inclusions’, exhibiting optical effects of the kinds that fascinated him, not least the translucency of semi-precious minerals. The crystal orb refers in an innovative way to the crystalline sphere of the fixed stars, thus transforming Christ from the saviour of the world to the saviour of the cosmos. The other optical effect in the painting involves his notions of the working of the eye, with the hands shown more definitely than Christ’s face, akin to a ‘depth of field’ effect in photography. The optical softening of features also acts to render his emotional impact as suggestive and ineffable rather than overtly defined.

Abstract:
Digital wallet is expanding largely driven by the evolution of internet and smartphone penetration. Numerous digital wallet providers have risen in many countries including Brunei Darussalam. However, the level of adoption is still low, and cashless society is still far from an expected target. There's no magic formula in deploying a guaranteed successful digital wallet, but developing a digital wallet ecosystem that is tailored to the local markets will be expected to increase digital culture and cashless society. The research assesses the existing digital wallet ecosystem, then analyses the extent of compatibility of local market demand. Furthermore, it introduces an improved digital wallet ecosystem model in order to support financial inclusion achieved through a holistic digital wallet ecosystem. The chapter also examines external factors that contribute to the digital wallet ecosystem's width of usage.

Abstract:
As a form, science fiction conceals homogeneity beneath apparent diversity. The diversity can be seen by looking at the range of paperbacks in any bookshop. One finds lumped together ‘end of the world’ stories, galactic empire stories, stories of the near future and, via time travel, of the very far past, as well as stories that have nothing to do with science at all but depend on magic, or the fantasy type known as ‘sword and sorcery’. One might well think that the inclusion of all these under one heading is just a mistake, that the diversity is genuine. There are two reasons for thinking that is not so: that there is something holding all this diversity together. One is temporary and practical; the other is an element that regular readers recognise, something that forms a large part of the genre’s appeal....

Abstract:
While chapter 1 focuses on religion-oriented articles in fashion magazines, which situated Christianity alongside fashion, this chapter examines advertisements, which explicitly merged Christian language, concepts, and gestures with the world of fashion. This inclusion simultaneously demonstrated the de facto Christian character of the fashion industry and how fashion advertisements constructed a particular way of seeing Christianity. This chapter analyzes how fashion advertising’s visualization and materialization of Christianity constituted an important step in the movement of religious symbols from the textual and visual discourse surrounding fashion to its material embodiment in fashion accessories and attire. In combining elements of fashion with those of Christianity, advertisements made over Christianity into a modern and sophisticated consumer-oriented enterprise. These advertisements established Christian churches as places to exhibit fashion; put a modern twist on Christian theological concepts, such as miracles and angels; constructed Eve as a chic Christian heroine; and infused Christianity with some modern magic.

Abstract:
Scott intended to include ‘My Aunt Margaret’s Mirror’, a supernatural tale, and ‘The Tapestried Chamber’, a ghost story, in the second series of Chronicles of the Canongate. His publisher rejected them. Scott eventually sold the works for inclusion in The Keepsake, an elegant gift book. As communal fora for short fiction such ornate books did not allow for the same anonymity as the experimental, character-driven periodicals in which Scott first explored the shorter mode. Gift-book stories and poems might reasonably be construed as safe, homely works attached to dependable authors. However, these highly inventive stories are not cast-offs but recastings finely attuned to a bespoke word-and-image forum. To keep readers interested, Scott would need to employ some new tricks – as well as the old ones – within a condensed space. His Gothic gimmicks – a magic lantern show and a family ghost – apparently have little impact on the plots. But the unsettling effect they exert on the reader is real enough, thanks to the trusted skills of the narrators.

Full text
Abstract:
The Port Leyden nelsonite is small magnetite-apatite-ilmenite ore body occurring in Mesoproterozoic metapelitic gneiss on the western margin of the Adirondack Highlands. It is unusual in that no compositionally adequate parent magma (e.g. jotunite or oxide-apatite gabbronorite) has been identified in the area (Darling and Florence, 1995).The nelsonite typically contains elevated levels of Zr (1400 to 2500 ppm) largely present in abundant modal zircon. The Zr abundances are considerably higher than normal levels of Zr solubility in non-peralkaline melts and suggests that some of the zircon modal fraction is inherited (Hanchar and Harrison, 2003).The zircon grains display both euhedral, oscillatory zoned cores (interpreted as igneous) and anhedral, irregular, compositionally homogeneous rims (interpreted as metamorphic or igneous). The oscillatory zoned cores contain small (2-10 micrometer), solid inclusions that have energy-dispersive X-ray spectra (EDS) consistent with quartz, K-feldspar, plagioclase, biotite, and apatite. Remarkably, no low-silica mafic mineral inclusions (e.g. orthopyroxene, clinopyroxene, olivine) were observed in zircon.Felsic mineral inclusions in zircon from an igneous rock that has mafic magma affinities provides further evidence that the included cores of zircons in the Port Leyden nelsonite are inherited. This unusual occurrence may be possible considering that the mafic igneous rocks described above are part of the bimodal anorthosite-mangerite-charnockite-granite (AMCG) magmatic complex in the Adirondacks (McLelland et al, 1988). It is conceivable that during magma mixing, zircon from granite or charnockite may have become incorporated into coeval jotunite or oxide-apatite gabbronorite. Subsequently, the latter magma experienced either unmixing (Philpotts, 1967) or crystal settling (Dymek and Owens, 2001) to produce the Port Leyden nelsonite.

Abstract:
In this article we outline our practices for the inclusion of electronic translation devices in specialized French language courses and reflect upon the changing landscape of language teaching. We describe how the use of Google Translate can increase students' awareness of linguistic, stylistic, and cultural differences in our culturally and linguistically diverse clasrooms. Although we characterize our didactic approach as action based, we differenciate our use of this approach from its common use in general language courses and point out the usefulness of intellectualizing it based on our use of Google Translate in work-place-oriented courses. Furthermore, we use our experience with action based approaches and translation devices to answer the following questions: why are students still learning languages; what are the language skills that they are interested in; and what is the role of a teacher in this new world of quasi-magic linguistic tools.

Abstract:
Volcanogenic massive-sulfide (VMS) deposits may have had metal contributions from magmatic degassing and leaching of footwall rocks. The Windy Craggy Cu-Co-Zn VMS deposit in northwestern British Columbia may include magmatic contributions, based on laser-ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) of fluid inclusions (enriched in Sb, Sn, and Bi) and lithogeochemistry. Sulfide-mineral trace-element abundances in the massive-sulfide orebody, underlying stockwork zone, gold zone, and altered and unaltered mafic rock and argillite were analyzed by LA-ICP-MS. Elevated Au, W, As, Bi, Sb, Se, Te, Tl, Ag, Co, and Mo contents occur within the gold and/or stockwork zones. Increasing 'magmatic metals' with increasing Co/Ni values suggest direct magmatic contribution to the deposit. Covariation of Co with these so-called 'magmatic elements' indicates that it, too, may be of magmatic origin, sourced via fluids exsolved from a crystallizing magma; however, evidence from the composition of rocks and sulfide minerals from Windy Craggy and other VMS deposits suggests that there is probably no meaningful distinction between hydrothermal leaching and direct magmatic contributions and that most - if not all - fluids that form VMS deposits should be termed 'magmatic-hydrothermal'.
