Cross‐Scale Seismic Anisotropy Analysis in Metamorphic Rocks From the COSC‐1 Borehole in the Scandinavian Caledonides

Metamorphic and deformed rocks in thrust zones show particularly high seismic anisotropy causing challenges for seismic imaging and interpretation. A good example is the Seve Nappe Complex in centralSweden, an old exhumed orogenic thrust zone that is characterized by a strong but incoherent seismic reflectivity and considerable seismic anisotropy. However, only little is known about their origin in relation to composition and structural influences on measurements at different seismic scales. Here, we present a new integrative study of cross-scale seismic anisotropy analyses combining mineralogical composition, microstructural analyses and seismic laboratory experiments from the COSC-1 borehole, which sampled a 2.5 km-deep section of metamorphic rocks deformed in an orogenic root now preserved in the Lower Seve Nappe. While there is strong crystallographic preferred orientation in most samples in general, variations in anisotropy depend mostly on bulk mineral composition and dominant core lithology as shown by a strong correlation between these. This relationship enables to identify three distinct seismic anisotropy facies providing a continuous anisotropy profile along the borehole. Moreover, comparison of laboratory seismic measurements and electron-backscatter diffraction data reveals a strong scale-dependence, which is more pronounced in the highly deformed, heterogeneous samples. This highlights the need for comprehensive cross-validation of microscale anisotropy analyses with additional lithological data when integrating seismic anisotropy over seismic scales. 1 I n t r o d u c t i o n Seismic anisotropy is a powerful tool to investigate the continental crust at depth. In the upper crust, the anisotropy of seismic wave propagation is generally associated with layered sedimentary basins or extensively fractured regions, where in the former the anisotropy is caused by bedding (e.g., Bois et al.,

Quantitative and Qualitative Aspects of Advanced Learners’ L1 and L2 Mastery of Polysemous Words

In the present investigation, 15 fi rst-term university students were faced with forty decontextualised polysemous words in English (L2) and Swedish (L1) respectively and asked to indicate which, of a set of six meanings, adhered to the item in question (two to fi ve of the meanings were correct). The polysemous words were of varying frequency. The investigation thus addresses the following research question:In quantitative and qualitative terms, what knowledge do advanced students have of polysemous words in their L2 as compared to their L1?Results show that most students have a relatively poor knowledge of polysemous words in both languages, especially in their L2. Furthermore, while the frequencies of the test items have no impact on the students' achievements, the relative frequencies of the meanings of the test items and the number of meanings of each test item stand in direct relation to whether the item is known or not in both languages.

“…The literature on the political economy of media has grown rapidly and several excellent surveys have already been written on this topic (DellaVigna and Gentzkow 2010;Prat and Strömberg 2013;Sobbrio 2014;Strömberg 2015). Nevertheless, most of the empirical research has thus far focused on highly consolidated democracies (e.g.…”

The television channel TV3 has played a controversial role in the Catalan politics since its creation in the early eighties for its alleged partisan bias and support for the Catalan secessionist movement. This paper examines the impact on electoral results stemming from the exposure to TV3 exploiting its staggered expansion across Catalan municipalities in the 1980s. We find that the introduction of TV3 increased voter turnout in the 1984 Catalan parliamentary election, but it did not have a significant impact on the share of votes received by Convergència i Unió, the Catalan nationalist force that has been commonly associated with this channel since its foundation.
