Contrasting textural record of two distinct metamorphic events of similar P-T conditions and different durations

2005

A structural, metamorphic and geochronological study of the StareMesto belt implies the existence of two distinct metamorphic events of similar peak P-T conditions (700-800 � C, 8-10 kbar) during the Cambro-Ordovician and the Carboniferous tectonometamorphic events. The hypothesis of two distinct periods of metamorphism was suggested on the basis of structural discordance between an undoubtedly Carboniferous granodiorite sill intrusion and earlier Cambro-Ordovician fabrics of a banded amphibolite complex. The analysis of crystal size distribution (CSD) shows high nucleation density (N0) and low average growth rate (Gt) for Carboniferous mylonitic metagabbros and mylonitic granodiorites. The…

Using calculated chemical potential relationships to account for coronas around kyanite: an example from the Bohemian Massif

2010

Corona textures around kyanite, involving for example zoned plagioclase separating kyanite from the matrix, reflect the instability of kyanite with the matrix on changing P-T conditions, commonly related to decompression. The chemical potential gradients set up between the kyanite and the matrix as a consequence of slow Al diffusion drive corona development, with the zoning of the plagioclase reflecting the gradients. Calculated mineral equilibria are used to account for corona textures involving plagioclase ± garnet around kyanite, and replacement of kyanite by plagioclase + spinel symplectite, in quartz + plagioclase + K-feldspar + garnet + kyanite granulite facies gneiss from the Blanský…

Plagio en trabajos académicos: diagnóstico y prevención

2020

Este documento recoge los contenidos del proyecto “Plagio en trabajos académicos: diagnóstico y prevención” financiado por el Vicerectorat d’Ocupació i Programes Formatius de la Universitat de València dentro de la convocatoria de Proyectos de Innovación Docente (UV-SFPIE_PID19-1095709). El plagio, en sus diferentes modalidades, constituye un fenómeno ampliamente extendido entre el alumnado universitario, hasta el punto de que incluso se llega a considerar como una práctica normalizada que no merece una excesiva penalización. Este trabajo trata de impulsar la pedagogía acerca del plagio, incidiendo en cuatro pilares esenciales: el desarrollo de instrumentos que faciliten la compresión de lo…

Corundum Anorthosites-Kyshtymites from the South Urals, Russia: A Combined Mineralogical, Geochemical, and U-Pb Zircon Geochronological Study

2019

Kyshtymites are the unique corundum-blue sapphire-bearing variety of anorthosites of debatable geological origin found in the Ilmenogorsky-Vishnevogorsky complex (IVC) in the South Urals, Russia. Their mineral association includes corundum-sapphire, plagioclase (An61&ndash

Plagiarism and predatory journals: A threat to scientific integrity

2018

This article presents an analysis of the concept of plagiarism in order to show the wide spectrum of manifestations that can be considered as such when committing a transgression of intellectual property, carried out with the intention of deceiving the authors’ true contribution and the originality and novelty of the information. It describes the different circumstances in which intentional plagiarism has occurred, and the damage that this misconduct causes in the credibility of the scientific system, in which authorship credit is the foundation of the academic career, of the prestige of the author in the scientific community, and the basis for financing research. Some circumstances are fav…

Pedagogical approaches for e-assessment with authentication and authorship verification in Higher Education

2019

Checking the identity of students and authorship of their online submissions is a major concern in Higher Education due to the increasing amount of plagiarism and cheating using the Internet. The literature on the effects of e-authentication systems for teaching staff is very limited because it is a novel procedure for them. A considerable gap is to understand teaching staff' views regarding the use of e-authentication instruments and how they impact trust in e-assessment. This mixed-method study examines the concerns and practices of 108 teaching staff who used the TeSLA—Adaptive Trust-based e-Assessment System in six countries: the UK, Spain, the Netherlands, Bulgaria, Finland and Turkey.…

Plagiarism Defined? : A multiple case study analysis of institutional definitions

2020

This multiple case study examines seven institutional documents from universities in four countries (Australia, China, Finland and Germany) with the aim of determining how plagiarism is defined in these institutional contexts. This research expands on previous analyses of university plagiarism policies in the Anglosphere (e.g., Kaktiņš, 2014; Sutherland-Smith, 2011), and particularly the notion that institutional definitions of plagiarism contain “six elements” (Pecorari, 2002). Using the six elements model of plagiarism as a theoretical basis, the documents in this study were analysed using deductive content analysis. The findings of this analysis revealed that the definitions of plagiaris…

Pore and mineral structure of rock using nano-tomographic imaging

2015

ABSTRACTIn order to better understand the micrometer-scale structure of rock and its transport properties which arise from it, seven monomineral samples from two sites (Olkiluoto and Sievi, Finland) were studied with micro- and nanotomography and scanning electron microscopy. From the veined gneiss of Olkiluoto we studied biotite, potassium feldspar, plagioclase (composition of oligoclase) and cordierite, and from Sievi tonalite biotite and two grains of plagioclase (albite). These minerals were the main minerals of these samples. Samples were carefully separated and selected using heavy liquid separation and stereomicroscopy, their three dimensional structure was imaged using X-ray tomogra…
