Microstructural and crystallographic fabric analysis of stretched-pebble conglomerates in central Vermont
Microstructures and quartz crystallographic fabrics of conglomerate lenses from the Tyson Formation, which composes the basal portion of the authochthonous Paleozoic cover sequence in central Vermont, were analyzed to investigate the complex deformational history associated with a polydefonned …

Identification of Fold Hinge Migration in Natural Deformation: A New Technique Using Grain Shape Fabric Analysis
… with the folding event. Rf/phi grain shape fabric analysis was conducted for each sample and used to calculate the orientation and magnitude of the final grain shape fabric ellipsoids. Flexural folding and passive-shear folding models predict that the highest finite strains will be recorded …

AnalyzeThis: An Analysis Workflow-Aware Storage System
… for expediting I/O, but also for the in-situ analysis of the simulation output data on the flash device. An array of such active flash elements allows us to fundamentally rethink the way data analysis workflows interact with storage systems. By blending the flash storage array and data …

Republican amphorae in the Auvergne central France
… from Western Europe. A detailed programme of fabric analysis,using thin-sectioning, of 408 rim sherds,has created96 fabric groups,many of which have been assigned to specific kilns. The distribution of Republican amphorae in the Auvergne and for the whole of France is studied and discussed. …

The formation, properties and behaviour of coastal soft soil deposits at Perlis and other sites in peninsular Malaysia
… tests, strength tests, chemical tests and fabric analysis were carried out on undisturbed samples obtained from the trial site.Field behaviour of the trial embankment was monitored using several types of instrumentation, including pneumatic piezometers, inclinometers and settlements plates. …

Washboard moraines in northeastern North Dakota
… moraines was determined by using pebble fabric analysis.</p> <p>Washboard moraines in northern Nelson County are generally 4 to 15 feet high and are spaced 250 to 550 feet apart. The moraines are subdued, discontinuous, irregular ridges paralleling each other. The moraines are composed of …

Aspects of Deformation and Strain in the Appalachian Fold -Thrust Belt (New York) and the Shear Zones of the Sveconorwegian Orogen (Norway)
… Rosendale. Normalized-Fry and Rf/&phis; strain-analysis methods suggest that this unit accumulated only very low shortening strains (e.g., Fry results yielded <3%; max. 8%). Notably, long axes of grain-scale fabrics revealed by Fry analysis do not consistently parallel regional structural grain …

Terrestrial cosmogenic nuclide dating applied in glacial stratigraphy and transportation studies on a greenfield exploration project in Kaarestunturi, Finnish Lapland
… different types of glacial transportation. Till fabric analysis shows that the Kaarestunturi and adjacent Kiimajänkä have been subjected to both pronounced and indecisive ice flow directions. The most strongly orientated till fabrics portray repeated flow from NE for the lower till units and a …

The primary structures and fabrics of the upper mantle and lower oceanic crust from ophiolite complexes
… outcrop. A detailed crystallographic and shape fabric analysis shows that they have,been formed by two different ductile shearing episodes. (D1 and D2). Both D1 and D2 are essentially simple shearing events. Individual olivine and orthopyroxene crystals deform by a combination of slip along …

The permeability of fine grained soils: an investigation into unconventional methods of measurement in the laboratory
… testing methodologies: BS, AP and RAP tests. Fabric analysis was carried out on specimens derived from post-test samples to assess the affect of testing methodology on soil fabric. Results produced indicate that AP testing in general<br/>underpredicts permeability values derived from the BS …

Structural setting and petrogenesis of Silurian granites in the Caledonides of northern Scotland
… been studied using field and microstructural fabric analysis. Their emplacement mechanisms and pre, syn or post-tectonic status with respect to phases of Caledonian ductile deformation have been detailed. The petrogenesis of the Strath Halladale and Helmsdale granites has been examined within …

Strain path partitioning during forceful emplacement of the Papoose Flat pluton, Inyo Mountains, CA
… pure shear or simple shear deformation. C-axis fabric analysis of quartz tectonites within veins in the gneissic border of the pluton, and quartzites within the pluton aureole, indicate that quartz tectonites deformed under approximately simple shear deformation, and suggest that the pluton/wall …

The role and fate of fluid inclusions in natural and experimental deformation
… of olivine grains, and a pervasive C'-fabric defined by the alignment of FIs. Like in the anneal experiments, samples that were hydrated by talc contain FI-rich and FI-depleted domains, but in this case domain boundaries have been distorted by deformation. Olivine pole figures obtained …

Desarrollo y aplicación metodológica para el análisis espacial de yacimientos paleolíticos al aire libre y en cueva
En esta Tesis Doctoral se propone un protocolo metodológico que permita la comprensión de las dinámicas de formación de un yacimiento, a partir de la combinación de técnicas espaciales ya empleadas en arqueología con otras aplicadas en otras disciplinas como la geología o la ecología. Para ello, se …

Nuove frontiere dell’analisi dei dati mineralogici e strutturali nell'era del machine learning: strumenti per la petrografia moderna
Nell'era della digitalizzazione e dell'analisi dei big data, la petrografia può trarre vantaggio dall'implementazione di tecniche di data science su dati geologici (geodati), come gli algoritmi di machine learning (ML). Lo scopo di questo lavoro è fornire tecniche statistiche basate sui geodati …
