Electron Backscatter Diffraction (EBSD) data from metabasaltic fault rocks, Woodlark Rift, Papua New Guinea
No full textHere we provide compositional and crystallographic orientation data on metabasaltic fault rocks exhumed by the Mai’iu fault in the footwall of the Suckling-Dayman Metamorphic Core Complex, SE Papua New Guinea. The present dataset was collected with a SIGMA-VP field emission gun scanning electron microscope (FEG-SEM) equipped with an electron backscatter diffraction (EBSD) detector at the University of Otago, using 30 kV acceleration voltage, 50–100 nA beam current, 20–30 mm working distance and 70° sample tilt. Electron backscatter patterns (EBSP) for the mineral phases actinolite, epidote, titanite, albite, calcite and quartz were collected by an HKL Nordlys camera and indexed with the AZTEC software by Oxford Instruments. The analysed fault sequence includes five units: a) non-mylonitic schist (protolith); b) mylonite; c) foliated cataclasite; d) ultracataclasite; and e) gouge containing the principal displacement surface. To resolve the microstructures of this fault sequence, step sizes between 0.2 µm and 5 µm were used. This detailed dataset reveals changing deformation processes in the Mai’iu fault rocks as the footwall was exhumed towards the Earth’s surface. A processed and interpreted version of this EBSD dataset can be found in the doctoral dissertation by Mizera (2019): “Deformational Processes Accommodating Slip on an Active Low-Angle Normal Fault, Suckling-Dayman Metamorphic Core Complex, Papua New Guinea.” (http://hdl.handle.net/10063/8666).
The EBSD data is provided in a folder with 25 subfolders for 25 samples. Detailed information about the sample locations is given in the file EBSD_sample_locations_and_structural_orientations.xlsx. Contact person is Marcel Mizera - Utrecht University - [email protected]

CAPRI versus AGLINK-COSIMO: Two partial equilibrium models - Two baseline approaches
No full textThe agricultural modelling world has generated several models aiming at the analysis of the response of the sector to certain changes in exogenous mainly policy variables. Among those, the CAPRI modelling system developed by a consortium centred on the University of Bonn and the AGLINK-COSIMO model, a joint product of the OECD and the FAO, are well known and accepted as comprehensive tools. This analysis focuses on a qualitative comparison of both models and particularly on the process of setting up the baseline. The baseline is a medium-term projection of agricultural markets reflecting current policies and those already decided upon. This projection in turn serves as the base for comparisons when analyzing scenarios. It is shown that CAPRI uses generic and automatic procedures whenever possible for conducting the database and the baseline, while AGLINK-COSIMO puts more emphasis on expert knowledge in this process. Both approaches are shown to have certain advantages while the conclusion that a combination of them would potentially improve both models will be drawn from this analysis.CAPRI, AGLINK-COSIMO, Baseline process, Agricultural and Food Policy,

Jean-Marcel Jeanneney à l'OFCE - Fondations et contributions (1981-1989).
No full textJean-Marcel Jeanneney était un économiste rare, à la fois théoricien, empiriste et praticien. C’est son aventure à la tête de l’OFCE que ce livre raconte, ou plutôt qu’il laisse l’auteur lui-même conter au travers d’articles écrits depuis le premier jour de son premier mandat de Président de notre institution. Ce recueil s’ouvre sur une introduction qui rappelle l'attachement du fondateur de l’OFCE au « libéralisme intellectuel», cette indépendance vis-à-vis des idées reçues qu’il jugeait indispensable à la conduite de politiques publiques raisonnables. Il est ensuite structuré en trois parties dont les titres font écho à une oe uvre marquante de Jean-Marcel Jeanneney : Vouloir le débat public en économie, Une mémoire au service de la prospective et Écoute le monde qui vient : intégration globale et unification européenne. Ce volume est un hommage à la mémoire de Jean-Marcel Jeanneney mais plus encore à sa présence. Les textes rassemblés ici par Jean-Paul Fitoussi et Éloi Laurent nous rappellent l’actualité des enseignements les plus précieux de Jean-Marcel Jeanneney : honnêteté, courage et espérance.
Deformational Processes Accommodating Slip on an Active Low-Angle Normal Fault, Suckling-Dayman Metamorphic Core Complex, Papua New Guinea
No full textDetachment faults that can be shown to have slipped at dips <30° in highly extended continental crust are referred to as “Low-Angle Normal Faults” (LANFs). Their apparent low-dip angle exposed at the Earth’s surface contradicts Anderson-Byerlee frictional fault mechanics theory, which predicts that normal faults initiate at dips of ~60–70° and frictionally "lock-up" at dips <30–45°. LANFs also lack significant associated seismicity; yet, a small number of normal faults are demonstrably active today at low angles (<30°). To address the longstanding paradox of LANFs, this thesis focuses on one of the few known, and probably best-preserved, active LANFs on Earth: the Mai’iu fault in SE Papua New Guinea—a structure that bounds the topographic massif of the Suckling-Dayman Metamorphic Core Complex (SDM). In particular, three fundamental questions are investigated regarding LANFs by studying the deformational processes accommodating slip on the Mai’iu fault: (1) "How do continental detachment faults achieve low dips at the Earth's surface: do they originate as low-angle normal faults, or does the footwall of an originally steeper fault deform in response to a ‘rolling-hinge’ unloading process?”; (2) "What micro-scale deformation mechanisms accommodate slip on LANFs in a metabasaltic protolith, and how do they vary with depth—are LANFs prone to aseismic creep, or earthquakes, or both?"; and (3) "What stresses (principal stress orientations, differential stresses, stress ratios) drive slip on an active LANF, and how do they vary with depth?".
Structural field data and geomorphic data interpreted from GeoSAR-derived digital terrain models (gridded at 5–30 m spacing) and aerial photographs show that dip-slip on the active Mai’iu fault has exhumed a little-eroded, strongly corrugated, continuous fault surface on its footwall that is >28 km wide. The Mai’iu fault emerges from the ground at the range front near sea level with a northward dip of ~21°N (locally as low as ~15°) and flattens southwards over the ~3 km-high crest of the domal SDM. The southernmost mapped portion dips ~12°S. Uplift and exhumation of the footwall was accompanied by progressive back-warping of both the exhumed fault surface and an underlying foliation through >26° about an axis parallel to the fault strike. Antithetic-sense (i.e., northside-up) dip-slip motion on a widespread set of faults that cut the exposed footwall of the Mai’iu fault, and strike parallel to it, accommodated some of the inelastic footwall bending that caused the Mai’iu fault to develop a domal shape. In agreement with this rolling hinge-style bending, bedding-fault cutoff angles in a stranded rider block of former hangingwall rocks indicate that the Mai’iu fault had an initial surface dip of ≥40°. Today, aligned microseismicity 12–25 km downdip of the Mai'iu fault trace delineates a convex upward fault zone that steepens downward to a 30–40° dip.
Detailed microstructural, textural and geochemical data combined with chlorite-based geothermometry of fault rocks rapidly exhumed from 20–25 km depth (T~425°C) reveal the processes operating inside the Mai’iu fault zone. Deformation in mylonitic rocks in the footwall of the Mai’iu fault is controlled by sliding and rotation of a pre-existing fine-grained (6–33 μm diameter) mafic assemblage together with syn-tectonic chlorite precipitation. This diffusion-accommodated grain-boundary sliding in the mylonites took place at >270–370°C. At shallower levels (T≥150–270°C), the mylonites are overprinted by an overlying <3 m thick zone of foliated cataclasite. Fluid-assisted mass transfer and metasomatic reactions created the foliated cataclasite fabric during inferred periods of aseismic creep. Pseudotachylites and ultracataclasites mutually cross-cut both the foliations and one another, recording repeated episodes of seismic slip. In these fault rocks, paleopiezometry based on calcite twinning yields peak differential stresses of ~140–185 MPa at inferred depths of 8–12 km. These differential stresses were high enough to drive continued slip on a ~35° dipping segment of the Mai’iu fault, and to cause new brittle yielding of strong mafic rocks in the exhuming footwall of that fault. In the uppermost crust (<8 km; T<150°C), where the Mai’iu fault dips shallowly and is most misoriented for slip, active fault rocks are clay-rich gouges containing abundant saponite, a frictionally weak mineral (μ<0.28).
In summary, the Mai’iu fault evolves by the "rolling-hinge" mechanism involving progressive flexural back-tilting during exhumation of an originally moderate dipping fault. The Mai’iu fault is frictionally weak near the surface, where the fault is poorly oriented; the fault is strongest at 8–12 km depth, where it both creeps and nucleates earthquakes. Locally high differential stresses drive this slip on a part of the fault that is not particulary misoriented. This research elucidates the mechanics of low-angle normal faulting in the best-exposed and fastest-slipping LANF on Earth

Marcel Schwob Digital Collection
No full textThis project outlines the discovery and digitization of previously unpublished correspondence composed by late 19th century author and literary critic, Marcel Schwob. Inspired by the inquiry of Bibliothèque Nationale Librarian Bernard Gauthier, Professor Daryl Lee alerted me to the presence of Marcel Schwob materials at BYU. I found that former BYU Professor John Green established a Marcel Schwob Memorial Collection and successfully published two books using the materials he gathered: Chroniques and Correspondance Inédite. After thoroughly researching the catalogued Schwob materials at BYU and comparing the contents to other Schwob publications, I found 72 previously unpublished letters. The majority of the letters (62) were written by Schwob to family members, and the remaining 9 letters were written to Schwob by colleagues. International interest in Marcel Schwob materials is one of many indicators representing renewed interest in the author, his work, and his influence. Recent publications also reflect growing Schwob interest. In Marcel Schwob, d\u27hier et d\u27aujourd\u27hui (2002), Christian Berg and Yves Vadé shed new light on Schwob through the observations of his contemporaries and modern-day essays on the importance of his contes. In addition, Jean Lorrain: Lettres à Marcel Schwob (2006) furthers the effort to better understand Schwob through a collection of correspondence. In light of this renewed interest, I determined that the previously unpublished correspondence would serve as a useful research tool for Schwob scholars. With the guidance and assistance of employees at the Harold B. Lee Library, I subsequently converted the correspondence into a digital publication. Creating a digital publication is a multifaceted undertaking requiring the involvement and expertise of different individuals and library departments. I successfully learned how to use both the hardware and software involved in the digitization process, thereby facilitating my completion of project deliverables, including: scanning and transcribing the letters; writing letter summaries (in both French and English), extracting names, and completing other metadata; uploading metadata using the Lee Library\u27s external database; establishing authority control records; writing website content (in both French and English), and publicizing the project. This document contains the major deliverables found in the digital publication, specifically the website content, the letter transcriptions, and the metadata
